    Re: Fun with the 645D

    I use my M9 quite a lot, and since March, I have about 2000 shutter clicks, so to reach the 645D's 50,000 shutter clicks is reasonable at that rate. However, I can easily shoot 500 images in a day for a client, but again this camera is intriguing and I would use several cameras to add to that shutter count. I am also curious about lenses and the absolute best for this system. It really comes down to the glass and its resolving power, and from what's posted in these galleries, i'd say the 645 D's is becoming a viable contender!

    Nature put on quite a show last night -dramatic sunset and a cresent moon appearing through the clouds. Same lake that was covered with ice a few months ago. No saturation or any other enhancing PS work. 45-85mm

    Not sure if anyone knows if the 50,000 figure is just a conservative estimate or not, so its hard to say. Lets say for example you kept up the rate of shooting with a 645D as you have initially with your M9...then you would reach 50,000 in a little over 8 years. Thats assuming you would keep up that rate all year long. How much I would worry about this aspect, I'm not certain.

    Regarding lenses, many have excellent resolution, especially when stopped down. They don't compare to S2 lenses in general and certainly not when used wide open as many do with the S2. As important as it is to pick those focal length lenses that are noted to have excellent performance, sample selection with many is equally important and thats a fact thats often overlooked with those purchasing the FA af 645 lenses (unless one shoots at beyond f9.5 all the time. Lastly careful adjustment of the 645D AF fine tune in the body with each lens I found is a must and makes a substatial difference with some lenses and samples.

    Wow Tom, stunning colors...and very dramatic! IS there any way for you to lighten the lake just a little? I hadn't noticed it was actaully a lake (vs. solid ground) till you mentioned it, but I think if it stood out just a fraction more, it might enhance the impact of the image.

    Interestingly, in my neck of the woods we've been having similar skies (that striking purple-orangy colors at sunset and I would have stopped, but alas the foreground to the sky I noticed while driving (and in the area I was at the time), can't come close to matching yours....That is if one considers a foreground of McDonalds, Burger King's and strip malls an attractive addition to such an image? I think not and no doubt would take your image with lake anyday of the week. Really nice Tom!

    Camera companies tend to be conservative with this number, but there are older cameras with more mileage on them than this (that is about 1400 rolls of 35mm film or 4200 120 rolls). But look at it this way, that is 20 cents per exposure. You can change that to your clients.

    Thanks Dave. I tried lightening the water, in fact I have 3 exposures at + 2 EV for HDR. I didn't like the way it looked, very unnatural to my eye. I only spent a few minutes this morning, may try again.

    I like the black water. I don't mind it is not obvious to the viewer. This allows some exploration of and mystery to the image.

    Hi Tom,

    As you know, it's all subjective and it was just a thought. Sometimes one looks at an image and thinks it might look better if an element is altered in some way...but after seeing the alternative perspective, it doesn't always work. All one can do is try and from your description, it appears your posted image is the one that's most effective. Thanks!

    Re: Fun with the 645D

    Well it wouldn't be the 4th of July without the obligatory 4th of July fireworks shot

    For a variety of logistic reasons, this shot taken with the 645D and FA 300 f4 lens was not from my usual vantage point for capturing fireworks, which generally is with the backdrop of the Potomac River along with the Nations Capital, Washington monument (among other historic monuments & buildings). Those images were taken with the Nikon DSLR a bit earlier. In trying to get an alternative view, I quickly moved equipment etc. a great distance, only to find on this one particular occasion, a very restrictive view due to the placement (or should I say misplacement) of a "Dept of Transportation" portable light tower assembly with wires, placed right in the line of sight. Grumble grumble. At one point, while quickly groping around in the dark to make on-the fly adjustments, I inadvertantly turned the ISO dial to both 400 (this shot) & 800 on others...rather than holding to my desired ISO 200.

    Hooray for the red white & blue

    7/04/2011 645D w/ 120 Macro, ISO 250

    Every year I make my trek to the roof deck of a building in Arlington VA to shoot the fireworks. The typical summer heat generates a haze which precludes crisp shots, but the D performed well in these conditions nonetheless. The detail is truly amazing, about twice as sharp as the D3x I used to use.

    Thanks all, it's appreciated! The reason I've been holding off posting images all this time is I've been in the process these past few months of deciding on a new "more secure" hosting site. In the recent past, I've had some serious instances of images of well known individuals/performing artists "lifted" for unauthorzed use. I thought once securing the secure hosting site, I would be able to post pics in their full web size (as most have posted) as opposed to the small images that have to be "clicked" 2-3x when loaded through Getdpi. Posting though a independent server is definitely a convienience and a much more attractive way of posting. Maybe if no one minds in the meantime (until which time I load my images onto a hosting site), I can continue to post here the usual way (through GEtdpi)

    Aboud, lovely shots of the fireworks with D.C. as the backdrop! As usual, you have a incredible vanatge point in which to facilitate some great shots!

    Dave (D&A): I LOVE the fireworks shot. Just for fun, I made an irregular outline around the obtrusive part and used Content Aware Fill. Hope you don't mind. I deleted it from my PC right after I posted.
    Great shot....

    Pentax 645D and 120mm A Macro f13 or 16, monopod. Converted to B&W with Silver Efex Pro, with orange filter, Plus X 125 film emulation. Edges and corners
    burned in, similar to my dark room prints. This image will go to 24"x32" no sweat.
    Best regards

    I first make the small low res jpg, usually 72 to 90 dpi, widest dimension 10". I then do select all and Edit>stroke, and put a narrow outline around the image. I then do a COPY. Then I make a new image and make it about 12" wide, the do a PASTE. This puts the image in a white mat. Then I select all, and Edit>stroke with a wider grey outline. It takes longer to describe it than it does to do it!

    Thanks for not commenting. A pretty bad example of HDR. I'm obviously still learning. I will stick to my polarizer and grad NDs. Two more 645D, 45~85 lens, polarizer, f13 monopod:

    Pentax 300mm A* with 1.4X

    I tested my 300mm A* today with and without 1.4 X Dedicated extender. I am very pleased with the sharpness. Shutter priority at 1/400 sec, mirror lock up. Camera selected f13 (reads f9 in data because of extender). First is a small jpg of entire frame. Second is a crop at actual pixels with 1.4X on the lens.

    Georgetown Marina Pano. 3 frames on 645D with 120 macro. Udo told me this was the lens to keep.

    Hi Dave,

    Don't mind at all. Actually two things about the image. I posted it quickly without any of the ussual color correction. Monument should be a bit more neutral. I actually left the partial building in the botton right hand corner on purpose when framing the shot, since this adds to the "sense of place"...but some might prefer it removed. I ussually shoot from a completely different vantage point but when the fireworks were about to start, the Dept of transportaion moved two large light towers right in the middle of the field of view and so thats why only part of the lower right hand building is shown. Thanks for the alternative view!

    Aboud, lovely shot! Both the645 MF 120 macro and the FA 120 macro are two of the best lenses for the 645D, hands down!

    Badlands, SD. The most amazing thunderstorm I've ever seen. Cloud-to-cloud and cloud-to-ground flashes for 3-4 hours. 30 sec exposure, so movement is visible in the clouds and the brush. 35mm A

    In a word...Wow....thats quite a capture (and storm too)! A week or so ago I was driving long distances and was caught in some tremendous lighting storms but as always the location I was at and the backgound and conditions, just didn't lend itself to any imagery. Well done! The movement of the clouds due to length of exposure, didn't detract from this image, in my opinion.

    Re: Fun with the 645D

    Hi,

    I am very curious about the 645D. What is the fastest flash sync I can get using wireless. I know the published speed is 1/125, but also it's mentioned that high sync speed can be achieved with wireless. Any insight would be appreciated.

    Re: Fun with the 645D

    The camera manual says high speed sync and wireless are compatible with the Pentax AF540FGZ and AF360FGZ flash models. You may be able to download the manual for those units from the Pentax website.

    Hi Shashin,

    Thanks for the reply, I would be interested in using this with a strobe kit with multiple flash heads and a wireless trigger. If I could get a higher flash sync, say 1/400 to 1/800, I would have ordered this camera already. Thanks.

    There's been a lot of discussion about this (top flash sync spped possible with the 645D) in other forums and evidence is scattered...meaning nothing with absolute certainty, one way or another. At least I haven't been totally convienced. With one of the Pentax manual focus LS lenses (which are plentiful and downright cheap), I think someone said they got their 645D to flash sync with a LS lens to 1/500th.

    I've used on occasion a couple of the latest Pentax 540 FGZ flashes with the 645D, but sync speed was at or below 1/125 for what I was shooting. I've been mostly on location with the camera as opposed to in the studio, otherwise I would have been using a multi strobe set-up and possibly would have had more definitive answers for you. I may in the future borrow one of the LS lenses and do some testing.

    Tom, you've posted many excellent images but the storm show in the Badlands is definitely one of your best. Nice capture!

    I'm not sure about wireless, but here's a shot I took after I read your post with the 135mm LS at 1/500 s using a 30-year-old 280T.

    Thanks for the comment Dave

    Tom, your shoot above of the flower (above) supposed my statede (a few posts above), that with one of Pentax's LS lenses, a sync speed of 1/500 is possible. I may be incorrect, but I don't see why it wouldn't be possible with this lens (LS) and wireless strobes? Of course nothing is a substitute foe actually trying such a set-up out.

    Re: Fun with the 645D

    Thanks for the replies. This is a good start...leaf shutter lenses! I haven't really given the 645D a real consideration until I saw a video of this camera being used in the rain! However, I shoot both landscape and studio and really need to use my Hensel kit with this set-up via wireless. Leaf shutters will get me closer to higher sync, so i'll try that route first. Thank you.

    I suspect it would work as well. At the very least, a small on-camera could be used to fire slaves.

    Exactly, I was thinking of the same senario!

    Fighting with the weather gods

    A week in California (Carmel, Monterey and San Francisco) didn't yield much. Lots of clouds and fog offered mostly flat light. In spite of that, here are a few images I managed to capture.

    I like the bridge shots Aboudd. I had the opposite weather problem at Yellowstone - sunny almost every day . Here's an exception. A shot of a photographer in the Hayden Valley and a actual pixel crop (400mm). Humans were the only wildlife to be seen that evening

    Re: Fun with the 645D

    Coming over from the Pentax K-5 forum having purchased a 645D. Bought a 55/2.8 A before making the purchase, using it on a Canon 40D. I use the garden on the other side of my fence as my studio. I am really impressed with this lens...haven't seen any raves for it in this forum, however.

    Re: Fun with the 645D

    Hi Roy:

    I see you took the plunge! In my experience and in the reports I've read, the 55mm is a good lens, sharp in the center and a bit weaker at the edges. For the images you've posted, soft corners are no concern. Many have found the 45-85mm zoom to be better than the 55 or 45mm primes. You pay a price in weight with that lens however. Did you buy the 645D new?

    +1 to what Tom expressed. The FA 45-85 lens is generally terrific, especially between 45-65mm and beyond 65mm, gets a bit weak in the corners/edges (varies from sample to sample). Unfortunately this zoom like many of the FA lenses, requires both finding a well calibrated sample as well as adjusting the 645D body's AF fine tune for this lenms. With zooms, the AF fine tune adjustment must be made with the lens at a focal length which has the most impact. On most samples of this lens, its generally between 65 and 85mm.
