Thanks DPR. I enjoy the videos.
I wonder if Ricoh will re-badge Tamron 15-30 f/2.8 & Tamron 150-600 S as Pentax lenses? Apparently, the new Pentax will be manufactured at the same Tamron plant as those two.
JJ1983: Am I the only one that finds it an actual pity that Ricoh Pentax does not make original lenses anymore, only rebrands?
Pity? FA 150-450 & FA* 70-200 f/2.8 are original Pentax lenses also the D FA 645 28-45 that was recently released.

Jim; I found nothing about Tokina/Nikon collaboration, except Tokina makes F-mount lenses of course. I did find this in Wikipedia;"As of March 2009, the six lenses co-developed and released in both Tokina and Pentax versions are the AT-X Pro 12-24mm f/4.0, AT-X Pro 16-50mm f/2.8, AT-X Pro 50-135mm f/2.8, AT-X 10-17mm f/3.5-4.5 fisheye, AT-X Pro 100mm /2.8 macro, and AT-X Pro 35mm f/2.8 macro."The Pentax DA*50-135 is considered by many to be optically superior to the Tokina ver. Maybe the Pentax ver. of 24-70 f/2.8 will be superior to the Tamron ver.
bernardf12: This is the benefit of IBIS. Cheaper and lighter lenses. Unless you look at super telephoto of course, then OIS should be included.
Did you hear that from a photographer?
Petroglyph: "The company says it will continue to listen and will investigate the development of a lossless compression system if there's sufficient user demand." -
Lossless compression will require a bigger processor and use more power - shortening battery life while reducing the file size. It would make a nice 3rd raw option (one that the other makers seem to offer OOTB). Yes, I'd like to see that option also if they can add it via FW to current cameras.
Good first step from Sony IMO.
Possibly, to hedge their bets & everybody would quiet down a bit. Sounds like the lossless compression will come eventually. I'll definitely load the FW as soon as I can.

Scales USA: I'd like to see lossless compression, but uncompressed? 130-150 MB files?? All other camera manufacturers use lossless compression for raws, you can save files to memory cards faster, and store many more images.
My Nikon D800 has uncompressed files on the order of 103 MB.
I hope Sony will clarify that they are using lossless compression. We should find out before long.
I agree, the 14-bit lossless compressed files (typical of Pentax and Nikon (and probably Canon) are about a 2X compression but don't loose any information and are easily interpreted by PP software. Sony always seems to have to go their own way. Could it be a type-O?
ttran88: Canon has DR starving sensors. Nikon has service advisories.Fujifilm has little MP sensors.Olympus and Panny has small sensors.Samsung has dish washers and fridges.Pentax has screw drive lenses.Sony had lossy Raw.
It's not fair game anymore Sony. Bring back lossy Raw.
Nikon has service advisories. - Okay a coupleFujifilm has little MP sensors. - Bet that will changeOlympus and Panny has small sensors. - Well they don't call it m4/3rds for nuttin'Samsung has dish washers and fridges. - And 4K BSI 28MP sensor.Pentax has screw drive lenses. - I guess you meant the plastic fantastics. Every lens lately for several years has a beefed up DC motor AFAICT.Sony has lossy Raw. - Not no more - :)
Glad to see it. Technically, it differs from a 16-bit Tiff (uncompressed file) by dropping the top two bits in a word. One probably didn't get any information from those bits in ADC anyway. Making this an optional selection in the menu is excellent and I look forward to seeing what the files look like.
Some of the technology for unloading the signal quickly would work well in a mirrorless cam (or live-view in dslr). Hand held sensor shift high-rez or global electronic shutter that has fewer artifacts.
RedDog Steve: Adobe's DNG file format also allows for some lossy compression. Not clear if Pentax also applies the lossy algorithm to their RAW (DNG) data.
Pentax raw format is PEF & is lossless 14-bit raw. DNG is supposed to be non-proprietary digital raw & can be any bit depth.
It makes the Sigma 35 Art even look a little small.760 gm vs. 665 gm.72mm filter vs. 67mm28cm MFD vs. 30 cm.106mm long vs. 94mm
What a stealth lens that Sigma is.
Looks like a 3:2 sensor at 45X30 for 1350 square mm & 37.5 MP. The Sensor in the 645Z is a 4:3 sensor at 44X33 for 1452 square mm & 51 MP. So a bit more cropped but should have big photo sites from the lower pixel count despite a slightly smaller sensor surface area. For comparison a FF camera has 864 square mm of sensor surface.
Hey, I didn't see the lens-mount disassembled in this series (or sitting with the parts at the last photo). That would have been interesting to see since I'm expecting a strong A7s-like mount on this model. Also, where is the 'dampened' shutter mechanism come to think of it?
This camera is such a step up from the previous model. They really ticked off a lot of boxes on my list. I am more confident now Sony will offer a lossless raw compression option for the A7 series cameras via firmware than I was before. My normal workflow, which results in a 16-bit Tiff in the middle, might need reconsideration, as my current over-clocked quad cpu seemed to bog down when I sent a batch of about 150 raws through the other day. Let alone sending a 4K vid through Power director or handbrake. Might be time to shop for a new CPU.
photoaddict: Wow, the pixel shift version does definitely show a huge improvement in resolution compared to normal version. Reminds me of Foveon images.
Please select "pixel shift" in drop menu to compare against normal images if you overlooked. I noticed some of you complained there's no difference.
I noticed the RAW file is massive - 123 MB for a pixel shifted file. Eeek!
Interesting, a Foveon tiff is about 120MB. I guess all that information has to be stored somewhere. Doesn't Silkypix convert the raw to something smaller though?
DPR, Thank you for including K3II pixel shift in the studio test scene. It looks like an excellent feature under limited circumstances (some product photography & maybe architecture). As technology is always evolving, I look for Pentax to possibly include this feature in their new FF camera this fall and subsequent models of the K3 might have hand held pixel shift or even moving subject capable PS. Won't those be interesting to see.
Interesting sensor technology. Sony will debut it in this model and, if it works out well move the tech up the line. The price might cause many to pause, myself included.
dholl: high-end Canons are "made in Japan". high-end Nikons are not.
I believe this fact bares further investigation as there lies the answer to Nikon's problems.
Right about that. Also, their shutter assembly are probably not manufactured in the same place as where the body is assembled in any case. I needed an excuse to go handle one in a shop, thx. :)
