    600 shots into a new A900...some observations

    I've had the A900 and lenses for a bit less than a week...about 600 shots.

    The build quality on the A900 is not as solid as that of the 5D, D300, and the D200.My particular favorite is the D200: solid, compact, fits my hand real well.First reaction when I took it out of the box: too plasticky.

    The on-off switch is in the wrong place (for me)...I'm used to the Canon and Nikon locations. The switch is not very sturdy, either.

    The CF card door is flimsy...every time I open it I have trepidations that it was the last time. The slot for the card seems more confined than on other cameras I have owned...I have trouble getting my pudgy fingers onto the release button.

    The viewfinder is really great...large and bright..no complaints here. The diopter wheel off to the side is another story. Again, too small for my pudgy fingers.

    The in-body vibration reductions works really well. Compensates very nicely for my shaky, 77 year old hands.

    The in-body dust reducer sounds and feels real nice...but...I picked up two dust spots the first time I switched lenses...and can't get rid of them.

    I have other observations that I would like to make (especially about the 24 MP sensor), but I'm afraid I will use up too much posting space, so I will defer for another time.

    Roy,
    Be careful with those new "dust specs" on the sensor (cover glass). They may be residual oil/lubricant from the mirror assembly. The sensor shaking will never dislodge them. Most cameras take a thousand or so actuations to "settle" all the dust and stuff, so you may be there with the A900. At this point, it might be worth trying to get a look at those dust specs and see if they are just dust or some residual lubricant specs. If the latter, one good wet cleaning should do the trick....maybe for as long as you use the camera. Once the sensor cover slip is thoroughly cleaned, the shake mechanisms seem to work really well at fending off new dust particles.....but they cannot dislodge anything really sticky. Just a thought.

    Thanks for the input, LJ. I agree with the oil residue idea...the dust spots would have vibrated off by now. The two spots (very small) only appear in a bald sky and are quickly and easily removed with the healing tool in PS Elements. So I'll live with the spots for now...but when they get to the salt and pepper skies that I get with my M8, I'll clean the sensor.

    Re: 600 shots into a new A900...some observations

    I was going to wait until tomorrow to make another post, but this issue has been nagging me since I started using the A900. The large files that are produced have really slowed computer functions down...and eaten up hard drive storage space. I have the early version of the Mac Mini which is perfectly adequate for processing files from the 10, 12 MP cameras...processing zips along pretty well in PS. But since I have been processing the larger A900 files, things have really slowed down. So...upgrade the Mac Mini? Go back to the 10-12 MP cameras? The M8 images, in my opinion, stand up to anything that I have gotten, so far, with the A900. I only print 11x17s and it's hard to tell the difference when comparing prints at arm's length.

    More later on the 24 MP sensor.

    Re: 600 shots into a new A900...some observations

    Roy be it in C1 or LR you can down res at the time of processing so you can make your files smaller. Now another trick and fair warning with it you don't want to edit the jpeg and than keep saving it, this will degenerate the file. But here is what you can do output the full 16 bit Tif file and do all your edits to it and get everything completely done. Now the file will be big and such but you will have to flatten any layers . Now from here you can save this as a jpeg and store it and it will be much smaller. Now here comes the warning again you simply don't want to keep playing with it at this stage and keep saving it as a jpeg at some point the file will go down.

    Now the real way out is get a bigger box with off line storage . I know not something you wanted to here but hard cold facts as you move forward in the digital era.


    Now if you can tell us what program you are using to process and what you have in the mini we might have some upgrade suggestions for you.

    Thanks for the input, Guy...and I appreciate the availability of more posting space. I'm using the LaCie Porsche 250 gb external hard drive(s). I don't save everything I shoot...only the stuff that will hang in the Louvre...but I store them as fully processed Tiffs and they do take up quite a bit of room. I'm using Photoshop Elements 6 to process...works fine...quick and easy with 10-12 MP output, but very slow with 24 MP output. I've been 8 bit processing, rather than 16 bit. I'm not really interested in downsizing using jpegs, for the very reason you bring up, which is the degradation of the image.

    I think upgrading my Mac would be the simplest and most beneficial first step...and I will look into that this week.

    Re: 600 shots into a new A900...some observations

    One other trick is doing the work in stages, renaming as you go ; save w/layers as name 1, flattening when fairly sure you are done, re-name, add more layers, save, flatten rename -etc., so you can always go back to the last stage if needed. That and purging histories as you clear a stage to free up memory.

    Other than the lower RAM and processor of the Mini, the other issue will be the graphics card - which is typically a little on the weak side in the mini. If thinking of upgrading, you can get nice-priced refurb machines from Apple directly. Latter copies of the iMac (if looking for a budget machine), for example can be stretched to 6GB RAM for (now with dropping RAM prices) very little coin using after-market kits. Check www.digilloyd.com's Apple performance section for some good info.

    Roy,
    If you have the time, interest and an espresso machine, here is a link to some performance ideas for Macs, and how to wring the most out of what you may have or plan to use. A lot of the stuff listed in this compilation has been discussed in various ways on this forum, but this is a good starting place to get up to speed.

    I'm surprised that you feel that way about the A900 build. It's got a magnesium frame internally, and a full magnesium shell, so maybe it's light weight is throwin you off??

    Ben,

    I agree with you about the CF card door which doesn't open enough and it is a bit awkward to remove the card. But that's about all what I agree with in your post

    Re: 600 shots into a new A900...some observations

    Hi Roy
    I'm with Douglas on this one. If it feels flimsy, it's because it's lighter than the D700, but I don't think there is any evidence that it's less tough (D700 card door isn't great either). Personally, in 10 years of digital cameras, I've only once broken a card door, and that was on an Olympus E1, which certainly had the toughest of all I've had (metal). I think that if you give them a good bang when they're open, they're all going to fail at the hinge, however solid the door might feel.

    Actually, I do agree with you about the on/off switch, but it's a small thing and doesn't take long to get used to.

    As for the processing - why not try Aperture or lightroom? it means that you don't have to save ANY tiff files, as your modifications are saved in a datafile and reapplied when you look at the image. It allows you to have any number of versions of a file without using more space. You could also convert the files to .DNG files, which are considerably smaller.

    But you are going to need a new computer - I use one of the new iMAC 24", and with 4gb of RAM it sings along with the A900 files in Aperture - added to which it is a joy to have around.

    I hope this helps

    Just this guy you know

    Re: 600 shots into a new A900...some observations

    Thanks, Jono, for the tips on Aperture and Lightroom...also for the info on the iMac. I'll look into these things today. I really enjoy your photos...especially the black and white ones.

    I'm sure I got off on the wrong foot with my A900 observations...initial remarks appear to be carping and petty (on-off switch, CF door, plasticky).
    I should have completed what I had to say rather than leave it as I did. The A900 is a fine camera...great viewfinder, handles well, easy to get at adjustments with the Fn button. I still have some issues with the 24 MP sensor...and the size and quality of the resultant files.

    I'm a 77 year old retiree who used to be in the business, but am now just a hobbyist who takes his camera with him on his daily South Florida walks. I enjoy the nice images that the A900 and the great Zeiss lenses produce, but my career doesn't depend upon my work output and I have other things I have to do other than process large files each day. Another thing: it takes twice as long to get the file from the computer to the printer.

    Thanks again to all for the advice, suggestions, and also some deserved criticism for my "sweating the small stuff" as my students used to remind me.

    6GB RAM isn't recommended/necessary per se, but many of the newer imacs (last gen included), if a viable upgrade for you, can be stretched as high as 6GB (again see the Llloyd Chambers site) if so desired.

    I second the recommendation for Lloyd Chambers site. His testing is very thoughtful and his tips on optimizing my Mac and Photoshop have been very worthwhile.

    Hey Roy, are you down Miami-way? If so I can give you hand picking out an iMac for your needs. I don't own a Sony, but I do own a D700 and a Mac Pro (which is quite beastly @ 8-cores + 12GB of RAM) and Aperture/LR2/C1-4 all sing on this system. Heck, I gave Hasselblad's Phocus a whirl this weekend with 50 Mpx images and it handled them quite nicely.

    Hi Roy,

    [hijack] Though I'm 4 years your junior, we have the same initials and are in some respects 'kindred spirits".

    I was sorta in the business when in the late 60s and early 70s I did weddings on weekends for 'pin money'. (Got so I could remove the spent roll of 220 film and insert another in the Graflex XL in 15 secs flat!) Only now has my interest in digital been kindled so my learning curve is very steep.

    I purposely stayed away from the MP kings and bought the D700 and, fortunately, my dual core Dell with 4GB RAM is handling my modest requirements with NX2 pretty well. No big numbers of pics to deal with, so this computer may work past when I'm working well!

    Let's keep on truckin', Roy. Ain't it a blast trying to stay with these talented young bucks and does? [/Hijack]

    Roy,
    While I would advocate something like a Mac Pro or MacBook Pro, that may actually be more than you may want and need. As Jono mentioned, the iMac is a decent machine also, and at a much more reasonable cost. There are a flurry of usual rumors about it being upgraded, possibly this month. The speculations are that it may be getting some of the newer, faster processors, and going with the dual video cards that are working rather nicely in the newer MacBook Pros. Those two features alone may make the iMac a whole lot closer to an entry point Mac Pro or even the higher end MacBook Pro, but at quite a bit less cost. Worth waiting to see what gets announced there. There is also talk of a Mac Mini refresh, but honestly, an iMac would run circles around the Mini. Stay tuned and watch for the Apple announcements.

    Re: 600 shots into a new A900...some observations

    From Mac Rumors


    Hardmac posts what it claims are the product numbers and rough descriptions of the iMac and Mac mini which are expected to be released tomorrow:
    The new iMac models and their corresponding references:
    - MB417: Entry level model
    - MB418: "Mass market" model
    - MB419: high-end model
    - MB420: ultimate model
    The entry level model should come with a 20" display, while the three other models will feature a 24" panel.

    For the Mac mini, the references are the following:
    - MB463: entry-level model
    - MB464 high-end model

    They cite a "reliable" source that has told them that both models will become available tomorrow. HardMac.com is the english counterpart to MacBidouille and are generally considered trustworthy.

    Earlier today a photo of the Mac mini packaging was leaked and is increasingly looking to be legitimate.

    Update: OneMoreThing.nl also "confirms" that the iMac and Mac mini will be released tomorrow and provides the following specs:
    Mac mini
    - 5x USB
    - 1x FireWire 800
    - 1x mini DVI
    - 1x Display poort
    - Nvidia chipset (net als de nieuwe MacBooks)
    - vanaf 2.0 Ghz Intel Core 2 Duo
    - 1 of 2 GB DDR3 ram geheugen (max 4 GB)
    - 120 GB harde schijf (max 320 GB)

    iMac
    - 1x 20" model, 3x 24" modellen
    - Intel Core 2 Duo (géén quad core dus): 2.66 Ghz, 2.93 Ghz en 3.06 Ghz
    - 1x Display poort
    - 20" 2 GB DDR3 ram geheugen, 24" 4 GB DDR3 ram geheugen (max 8 GB)

    Thanks to Cindy, Carlos, Roger, and LJ for their contributions to the computer search...if I could figure out how to PM each of you individually, I would.

    Carlos: I'm in Boca Raton. You bought my Zeiss 21 ZM, I believe.

    Furthermore, the consensus seems to be to upgrade the computer rather than dump the A900 system. I'm encouraged and grateful for all of your input.

    Roy Benson

    BTW: I just found the PM button...I'll try to contact each of you tonight. Thanks for your patience.

    I agree update the box and not the tool unless the tool is something you truly don't want . But i want one of those bad boys myself. LOL

    Thanks for the reference. FWIW we have 3 macbook pro's , 1 basic mac pro and two imacs.
    For photography the 24" 2.6Ghz imac is much MUCH MUCH faster than even the newest macbook pro - why? I've no idea, but it is the case.

    For processing A900 files in Aperture, a 2.6 Ghz 24" imac with 4Gb RAM is perfectly okay.

    Roy - you really should be using Aperture or Lightroom, if you are a professional trying to output large numbers of files for clients, then there are strong arguments for using Capture one or photoshop, but if you're doing stuff for your own pleasure you really do need to use a DAM with non-destructive changes, using TIFF files on a mac mini with small storage seems to me like real masochism

    Roy - looks like Apple just made your day. New Minis with 2.26Ghz C2Duo and up to 4GB RAM plus enhanced graphics processor for a very nice price. Keep the old mini as a music server, etc, keep your screen and away you go.

    You will want the most ram the fastest hard drive 7200 but I think they only offer 5400. Also go for the fastest processor . You cannot upgrade the processor after the fact so real important get that as priority the fastest processor . Ram and hard drives can be upgraded later and I think THINK they are user friendly to upgrade . Is that correct on the mini's

    Not sure on minis, but on iMacs and Macbooks RAM upgrades are easy (and MUCH cheaper after market). I suspect Minis are just as easy. HD upgrades on the laptops easily done - on the iMacs, it's not an options. Minis, not sure,

    That said, FW800 (or e-sata if macbook pro or mac pro) external 7200 drives are dirt cheap and getting cheaper and my personal pref vs one large internal drive.

    As said earlier, for anyone not really versed in this stuff, LLoyd Chambers site is awesome for all the gory details and recs, instructions, performance stats, etc. for choosing, upgrading and optimizing all varieties of Macs for photo processing - and at various budget levels

    Re: 600 shots into a new A900...some observations

    Greetings all, my first post here. As a new A900 user and something of a computer dunce, how much difference will there be between the three processors of the new imacs? I read Lloyd Chambers' site and he seems to think that there isn't a huge performance increase with the faster processors. FWIW, I'm a low volume shooter who won't be doing batch processing. I want to keep my computer expenditure as low as possible, without hindering my workflow, as I need some money for lenses!
    I'll also be using it to work on drum scans of 6x7 slides and B&W, also low volume.
    Thanks in advance for the help. It's great to see a dedicated Sony forum here.

    Cheers,
    Scott

    I did an undergrad degree in software design (before I wised up and went to business school ;>) and Lloyd's advice is on-the money in all aspects...and while I won't even attempt to replicate it here, some thoughts:

    You'll get the best bang for the $$$ in any computer by maxing out RAM as much as budget allows followed by ensuring fast hard drives (e.g. 7200 rpm+). Solid State Drives or SSDs (basically big internal CF cards) vs mechanical hard drives are the fastest, but still, as yet, spendy.

    The more memory the less swapping the machine does to/from disk and the faster tasks get done - and the less strain processing large files.

    Biggest mistake folks make is getting THE whopping processor and not having enough $$ left to max RAM and ensure fast drives. Like hooking a garden hose to a fire truck...

    CPU can't really be upgraded and if the upgrade fee is very modest and in-line with %'ntge increase in performance, it's not a bad idea if budget allows.

    E.q. 2Ghz-2.26Ghz = a 13% (on paper) THEORETICAL improvement in processing speed. However, that's on paper. A boost in clock speed for a processor doesn't necessarily (and usually does not) mean a linear improvement in processing speed. It varies by application, amount of RAM installed, HD speed - you get the idea..... That's why it's not always the best bang/buck.

    In our example, if price premium required is in-line with 13% or (ideally) better, it's worth it if the budget allows AFTER (stress AFTER) RAM is maxed and drives upgraded.

    Go for a decent internal drive at 7200 rpm if you can, partition it, etc as Lloyd suggests and then add cheaper external 7200+ rpm drives . No single point of failure, makes backups easier, etc. LC's RAID advice is also a VERY good idea for boosting performance and cost free if using APPLE.

    Oh, the other thing when buying a new machine is to make sure it has at least one Firewire 800 AND ideally an e-sata port and buy external drives with multiple interfaces (or a separate drive/enclosure system). Drives depreciate like a rock off a cliff and having a good 7200 RPM unit with multiple interfaces out the back can last you thru many computers.

    Problem is the applications C1 wants processing power and the more the better. Adobe products love ram. So it is a balancing act .Most folks tricks are buy the higher processor since you can't do that after you purchase but but your Ram and hard drives elsewhere at a cost savings and sometimes those cost savings a huge compared to what Apple sells there Ram and Hard drives for. The cost savings alone going outside the Apple store on Ram and Hard drives usually pays for the higher end processor. My issue right now is the processor. i have all my machines maxed out for the highest performance possible but now limited by processing speed in C1 due to the processor. So know what apps you will be running and what they like to run with. CS4 is a ram hunger pig.

    Gets even trickier when you start investing in Pros, etc - where some apps use the extra processors (read $$$) efficiently and some do not . Gotta love SW developers ;>

    I have the MBP 2.4 dual core and I just bumped the ram from 4GB to a 6GB kit from OWC for 175.00 there is a small rebate for my existing RAM which would reduce this price further. They say it should make a big difference in PS.

    Re: 600 shots into a new A900...some observations

    Well, I'm way past 600 shots now - much closer to 6,000! And I've used the a900 in -24C all the way to +36C temperatures. (I just got back from Polynesia - very hot!).

    For DSLR work, primarily wildlife, I'm a Canon convert so my comments tend to be based on my experience with the 1D series of cameras. (I use Mamiya/Phase for landscape work, so I deem myself pretty critical.)

    What I like about the a900 - fabulous viewfinder, great menu structure, easy MLU and delay, two batteries with the vertical grip, lovely tonality and SSS works with all lenses. (I always wanted Canon to produce an IS macro lens!) And did I mention lovely tonality?

    Things I don't like are quite minor - the SSS doesn't inspire the same confidence that you're steady as Canon's IS does, because you can't see it in action. But it does work. Also, the shutter sounds clunky because of the mirror's articulated design, I think. The a700 which I have as a back-up is much quieter.

    My only serious gripe is that if you leave the camera turned on, hanging around your neck, you can inadvertently change some settings. Seems some buttons/joystick can be depressed by one's chest or maybe belt buckle. This is especially true if you're using the vertical grip. I leave it turned off now until I need it.

    And finally - the lenses. My 24-70 Zeiss is way better at the short end than my 24-105 Canon was. The 70-300 G is fabulous as long as you can live with the smaller aperture. (Definitely better than my Canon 70-300 DO at the long end.) I like the 500 mirror lens but find I really need to use a tripod, despite SSS.

    The 300 f2.8 and a 1.4X arrived just before my trip and I didn't take it with me so I'm just now trying it out. It's heavier - I think - than Canon's 300, but at first glance gives results that are comparable. It is eerily silent in operation. I'll check it out thoroughly in the next few days and report with pix....

    And incidentally, much as I love Lightroom, ACR is a lousy converter for Sony files. Aperture seems best to me, but Capture One is very close and that's what I use for critical work because I use it for my Phase files, naturally.

    An unabashed fan,

    Bill

    Nice report Bill, love to hear more. That instilled a lot of confidence for me

    Try Ctrl dial Lock = ON in menu 2 of the Gear Menu.

    Then the dials etc only work after you wake the camera up with a half press.

    I learn something new every day! (I should have known, actually, as my Phase back has the same feature.)
    Thanks David,

    Bill, I'll admit it isn't obvious from the manual what that feature does and a few folks thought that you had to go to the menu again to unlock the dial each time, which of course would have been hopeless!

    Question Re: 600 shots into a new A900...dust .....

    I'm a new member and also a new owner of the Sony A900. I am interested in the comment that:

    "The in-body dust reducer sounds and feels real nice...but...I picked up two dust spots the first time I switched lenses...and can't get rid of them."

    The same has happened to me, but I have lots of small dust spots that are most visible on skies when apertures of F16 and F22 have been used (which isn't often). When I take shots at F5.6 through F11, the dust spots aren't visible. However, for a short time, I got a really large dust spot that the sensor shaker couldn't remove immediately, and this was quite visible even at apertures of F5.6 and F8.

    So are the dust spots you describe visible at wider apertures (which means they may be large spots) or can you only see them when you use smaller apertures, such as F16 and F22? If the dust spots aren't visible at the wider apertures, then to me, the dust problem isn't that significant and perhaps needs only to be dealt with when dust is showing on all the shots you take. Does anyone agree with this approach?

    I've had the A900 for 6-7 weeks now and 1000 shots done, I am just starting to see 1 single large dust spot which is by far better than my previous cameras. I have not even done an air blower sensor cleaning yet. For me, anything less than 10 visible spots is better dealt with in software.

    Yes, I think I could tolerate a single large dust spot if it only appeared on say F16 and F22 exposures, but if it was on all images, even those taken at wide apertures such as F5.6, then it must be a very large spot that an air blower may be able to remove. Although I usually have sucess in removing dust spots using the healing brush tool in Photoshop, I wouldn't like to have a large dust spot that is visible on all images that I take.
