    I especially like the Translucent Mirror design of these cams. Finally the first vendor to introduce EVF in their DSLR models - this will be the future I guess if we all like it or not

    I am still missing a new FF DSLR from Sony with Exmor sensor.

    Very interesting design for effective video AF.

    >Finally the first vendor to introduce EVF in their DSLR models - this will be the future I guess if we all like it or not

    Right, if the resolution and frame rates are fine we will be ok with it.

    Vidoe AF only with lenses wide open is a minor downer. Still very interesting.

    Looking good! Can't wait for the A75 and A95, should be cracking cams....always assuming that this is Sony's future road map.

    Sony are really going for it as the number of international patents posted by them indicate a really active future. They are deservedly following the Minolta pedigree of innovation IMHO.

    Looks good, except no viewfinder with continuous shooting, which leaves 10fps rather meaningless for most applications (unless one wants a long sequence of photos with the subject almost in the frame ).

    I hope the mirror could be locked up in future high end models to allow for manual focusing without the unnecessary light loss. This EVF will be great for mf.

    Really exciting developments!

    I hope the EVF and the swivel LCD will be implemented in the next iterations of the NEX line.

    BTW, does anyone use the Zeiss 24mm f/2? I can not find that listed anywhere here.

    I think I would go for a A55 / 24/2 combo.

    Not sure how this one works but it seems the LCD still works only the EVF blacks out. I would think panning would be easier with the LCD, but anyway I have never shot faster than 1 fpm so what do I know

    Michael Reichmann's article is very interesting.

    Not being familiar with Sony cameras, would my legacy lens collection I've amassed for my m4/3 system work with the A55 with appropriate adapters?

    It depends on what glass. The A55 is an A mount camera and not an E mount. That means that essentially non of the rangefinder lenses would work. because the mount is much further from the sensor than either M4/3 or the NEX. Old dslr lenses could potentially work but I wouldn't approach this camera in the same way you think of m4/3 or NEX but more in line with buying a regular dslr and the lens choices that go with that sort of decision.

    m42 lenses are the easiest to adapt to Alpha. Contax CY and Leica R can be adapted through Leitax. Just about everything else require DIY mount removal or an adapter with a glass element in it (bad idea.)

    I shoot motorsports regularly, and when panning at slow shutter speeds, you don't only need to keep the subject in the viewfinder, but at exactly the same place. I guess optical viewfinders still has a role to play

    When shooting high speed, once you fill the buffer (20 RAWs - 2 seconds of shooting) it takes 50 seconds to recover! ouch. No sports here.

    I suspect the higher end products in the pipeline, will have far larger buffers and will be significantly more capable.

    In Sony's lineup, these (the 3-series and the 5-series) are the equivalent of a Canon Rebel level product. The 7-series, the 8-series and the 9-series are the ones to look out for, when it comes to higher-end features.

    Another interesting aside is that if they are announcing the A33/55 this far ahead of Photokina, then the conclusion I can draw from that is that the A33/55 are small news from Sony's perspective.

    They are getting all of these small news items out of the way, for the big ones that are yet to be announced.....which in turn will get revealed at or around Photokina. Exciting times ahead.

    I have a lot of M42 lenses. Will an m42 to Alpha adapter happen, or does it exist already?

    Some interesting tidbits from a person who was at the Sony A55's launch. The first post and some of the following posts from the same user, has more interesting bits about the product.

    Or is it clever marketing: everybody is waiting for Photokina, where the releases will be flooding and some may go nearly unnoticed. Now they get all the attention.

    They are all over ebay. I personally went with one from James Lao, because you can have the adapter chipped, and therefore it reports info to the cam like focal length (helps with image stabilization.)

    Keith,

    As you can see in my signature, I am using 3 M42 lenses on my A900 and the results are excellent.

    To me personally the 10fps is good news for what I call the "Uwe approach", high speed bursts to increase dynamic range. I am also curious to see how the 70-400G will act as a 600mm in that respect. I would hope for very acceptable ISO 1600, but I am not holding my breath on that part, would be nice though.

    Look like a lot of bang for the buck. Hopefully as flawless a launch as the a900 was. Fingers crossed.

    I wonder though.... if they show the A700 successor soon, based on this new stuff.... differences should be very interesting! Still, that baby looks very sweet to me on the paper.

    First in the camera shop - but I'm actually rather seriously tempted.
    We'll see . . . if it was out on September 6th I'd snap one up for the Crete trip, things may be different by the end of the month!

    How about you?

    I can't disclose that just yet....or I really might be forced to actually launch a site with the name i own gearwhoredom.com

    Seriously, all of my gear is up for review. I enjoyed Ireland with the A900/NEX combo. That leaves me thinking about what I do with all my M4/3 gear. I'm a bit gun-shy to sell it until I have a better understanding of what Sony is going to do on the high end.

    Although, when I seriously analyze my shooting it is mostly with smaller cameras and then the A900 comes out to do landscapes. If that is the case I should really just have a small system and perhaps a tech camera for landscapes. Tech camera and a lens or two makes for a really small (but very expensive) kit and my day to day kit is really small. These small cameras with really good IQ have changed the game a bit.

    Very interesting, so PDAF requires the lens to be wide open? That kinda defeat the purpose for video...

    Also, does that means the fps is now limited by how fast the aperture can stop down for shots and open up for focusing in between shots?

    Hi! Is it possible to have a link where I could find James Lao adapters.

    I was able to find some on Ebay that are chipped and give AF confirmation. Do you think that would do?

    I feel like I'm in a situation that is a little similar. I really only see myself using the A900 for tripod work at this point, because the NEX IQ is so good for the size. I don't really need fast autofocus or anything. It'll be interesting if Sony brings an A99.

    Try this one: http://cgi.ebay.com/ws/eBayISAPI.dll...#ht_3508wt_913

    The English is a bit tortured but I bought two of them this spring. They set the focal length on the chip and the chip aperture can be set with the dial for the exif. Doesn't change the aperture in the lens just prints whatever you set with the dial to the exif.

    I'm pretty sure they still work the same way but as I said the english is a bit tortured.

    I take the chips off and put them on leica and contax adapters.

    Mike

    p.s. This is the same functionality that Lao offers for 3x the price.

    The initial article seems to bear evidence of Sony's claim that the Exmor sensor they've developed yields images at higher ISO's with lower noise (compared with previous Sony cameras anyways).

    While the 16 MP is certainly impressive I am wondering if with a lower concentration of pixel sites per cm2 whether the 14.2 A33 with it 3.9 MP/cm2 (vs 4.4 mp/cm2) may be the better camera of the two (although at these levels it may also be insignificant).
    Life is an infinite series of moments called..."now".
    My job is to capture them.

    It's tough to say, but more megapixels usually leverages the noise difference when you view the two images at the same size. ie. the more megapixels, more noise theory isn't usually applicable when it comes to actually printing or outputting jpegs for web.

    Not sure about the chip but you should stay away from aluminum adapters. They are too soft and particularly with a heavy lens can deform and result in poor focus. There is a good reason you don't see aluminum lens flanges on most lenses.

    I bought over a dozen of different adapters and most of what is sold on ebay is aluminum junk. The fit is lousy and the adapters are fragile. The best ones as I found are the Rayqual, built from one solid piece of brass. But they are expensive and not chipped, though I believe a chip can be added by the owner but I never tried that.

    So we are all happy or should be, about Sony's alpha mount DSLR future;-)

    I just got a look at the A55 with the new 24mm f2 on the LL review - it's tiny! 441 grams light, so what a great second camera to back up a big alpha with Sony's latest sensor - all for $750 release price...so it's not perfectly specced but is a very intelligent development by them - IMO.

    So good to see a new entrant innovating like this and the NEX. I feel if a player produces 1-2 fabulous middle market cameras, it reflects on all their output - let's hope so, and maybe Zeiss's cagey statement about more lenses might bear fruit also.

    That A55 sensor's pixel density will really stretch lenses, probably about equivalent to 40Mp in full frame...

    Actually the "cagey" statement about Zeiss lenses being developed for the e-mount, came from Masashi Imamura, the head of Sony's Imaging and Sound groups.

    I would not be surprised to see some of those during Photokina.
    A900 with a few lenses, flashes etc.

    I might buy one... lol...

    You can keep the 10fps though. To me, it says they're saying the AF is good... but 5 or 6 is I think enough...

    Auto HDR Built Into Camera
    Captures more scene dynamic range than a single exposure can handle-and more range than photo film. Combines the best highlight detail from one shot, the best mid-tones from a second and the best shadow detail from a third for one incredible shot. Captures in a split second. (Recommended for still subjects.)
    Sweep Panorama Mode
    Capture expansive landscapes automatically. Press the shutter and sweep vertically or horizontally. The camera does the rest, continuously shooting images and stitching them together. Up to 23 MP image size.
    The auto HDR sounds interesting and I wonder how well it would be in twilight or night/city pictures... probably would not get the stars in the sky, but probably would get the mountains in background... and also the panorama mode. I bought a Minolta 20 2.8, hopefully good, hopefully great with panorama mode... lol... I like taking photos, but am no computor whizz... New Zealand $1300 or so body only...

    I am near positive now that the a-55 will take the place of my Minolta 7D in October. My NEX 5 has made such an impression on me with its sensor that I am sure the a-55 will make a great complimenting camera to carry and use my A mount lenses on. I see the NEX with legacy lenses and the a-55 with alpha lenses as my mobile use equipment (with the NEX + adapter as backup for the alpha as well )

    The Minolta 7D has been a fine camera but at 6mp and with the weight with vertical grip it is dated and heavy equipment for carry use when other systems with great IQ are available today. Such as the a-55.

    I see the a-33 is now available here in the USA but the a-55 still has a October introduction date. This will be after the show which will be great so that nothing new will go unnoticed before purchase time.

    Anybody hearing any real deal breakers on the a-55 yet when using Minolta lenses or some issues that might be areas of concern. I have read something about "ghosting" but really didn't understand if it was just a viewfinder visible issue or if it was an image issue.

    Also saw a blip about a undefined issue with using some Sigma lenses ....

    For my needs .... if it produces IQ equal to or better than the NEX5 and can use my AF Minolta lenses and 5600 flash "off camera" I will be more than happy.

    DPReview and Luminous Landscape both talk about ghosting in their review updates. It isn't a viewfinder issue it is an image issue. It has to do with the light going through the mirror. Both have said you can find it if you look hard but it is not something that is a deal breaker.

    No matter how large the view Terry? I usually don't go over 8x10 or on screen views in presentations. You would think "ghosting" would kill IQ 100% of the time. Kinda like a very bad lens filters effect on film.

    Thanks for the heads up Terry .... I read it but really only half understood.

    My hope is someone on this site has gotten a a33 and has some feedback.

    I still do not have first hand experience on this wonderful toy.....coz lack of AF in Nex 5 really makes me to have an a55
