The Pentax K1, has gotten some good and bad press lately, but one review on Dpreview over a month ago really started a negative chain reaction. This review has since been corrected, but as with many things, first impressions tend to be the most important.
I wanted to attach 3 images, from a test I was working on yesterday. Good lighting, and a bit of wind. The wind was not consistent and tended to hit different parts of my scene with more or less force. What is so impressive to me is just how bad the LR conversion is vs the one from Silkypix. If all you have is LR or ACR for the K1, you really need to look to Silkypix for now. I have no faith that Adobe will attempt to revisit their current conversion for Pixel Shift on the K1, and I base this on the fact that Adobe never has fixed their less than stellar conversion for the Fuji X-trans files. The problems with that conversion have been known about now for over 2 years.
There are three images attached, the first two are Silkypix conversions on image 724 and a follow on image 725. The third image is LR’s conversion of the same file. The point being that if you are only using LR for Pixel shift raw conversions, you are more than likely missing a lot. The LR image is totally blurred and basically worthless, where as the exact same raw file from Silkypix is very good, in fact amazing, when compare the two conversions. The other Silkypix conversion is from the next shot, 725. I included this to show how the shadow area to the left of center improves considerably. Both conversions have a bit of trouble on the same part of the file in image 724, however more than likely the Silkypix conversion of 724 would hold up.
These conversions were done only for the effect to show the differences in blur recovery. By default I feel Silkypix has too much sharpening applied and a bit too my saturation. But a small price to pay for recovery of the image. You can also see in first two files that the part of the tree just to the left of center, in the shade, is still having trouble, even with Silkypix, as it’s blurred. However I took several test files and in the very next frame you can see much more detail in this same part of the image.
So for now, if you are using pixel shift or testing it, outdoors make sure you work with Silkypix Developer’s Studio. You can download the software for a 30 free trial and it’s not inexpensive at $295.00. It’s a issue to take into consideration if you are looking at the K1 as the extra cost of this software takes the K1 into the $2,100.00 range. Still a margin compared to other cameras in this class.
I would like to see Pentax step and address this software issue, by at least giving a coupon or discount towards the full Silkypix software, as their version which ships with the camera might as well just be left out of the box.

02/15/14 News from the CP+ Show in Japan–Pentax 645DII CMOS 50MP Camera
A view of the Pentax 645D 2014 from the back showing new LCD design
CP+ the Japanese eqvilent to the U.S. CES (Consumer Electronics Show) is going on through tomorrow. and one of the highlights as far as larger camera systems goes, is the information about the upcoming Pentax (now Ricoh) 645D2014. Instead of calling it the 645DII, it seems for now that the camera will be just called the 645D 2014. Interesting name indeed.
From looking at the announcement literature by Ricoh, this will be a pretty significant camera system for Medium Format users. Here are some high points that I gleaned from the overview.
Side by side shot showing the original 645D and the new 645D 2014
Pentax first shook up the Market 5 years ago, when they first started listing a new 645D Digital camera, that would be based on the Film Pentax 645II. I was originally excited by this announcement but Pentax did little more than talk about it for several years and showed mock ups. I owned several good Pentax 645 lenses, that I was using on my Canon system with a Zork adapter, so the 645D would have been a perfect fit for me. However the long delay, pushed me to the Phase One camp and I purchased the P45+.
Pentax did finally ship the 645D about 1 year later, with a similar sensor to the one in the P45+ (it’s my understanding it’s not the exact same sensor) and they brought out basically the body with no new lenses. About 1 year before the actual ship date of the 645D, Pentax had a pretty good lineup in their primes and zooms for the 645II in the FA lenses. I had both the 35mm FA (excellent) and the 55mm FA, and had been thinking about the 35mm to 55mm zoom. Since Pentax still had a manual aperture ring on all the FA lenses, you could stop them down on other camera systems, like the Canon with a Zork adapter. However by the time the 645D shipped Pentax was no longer selling the 35mm FA in the U.S. (it’s my understanding that this lens is still sold in Japan). Also there was not much of a dealer network in the U.S. so anything that involved service would be possibly a bit of an issue. All repairs were still done in Japan, and there was only a 1 year warranty. Phase One at the time had their 3 year (now 5 year) value add warranty and I found that I preferred that type of warranty, even though the cost of the 645D was much less than the P45+.
Now with the 645D 2014, Pentax is showing that they have listened to the photography market and it seems that they are bring out this new camera with some much needed refinements. For studio photographers, the lack of a tethering solution on the 645D was a big issue. I am assuming that the 645D 2014 will have tethering since it’s shipping with USB3 support. The LCD on the camera is significantly larger, has more resolution and provides more information to the photographer, not to mention it has a tilt option which allows the camera to be used at waist level (a big plus to me). The CMOS sensor should be 50MP, not a huge jump over 39MP from the first 645D, but if it’s the same sensor that’s in the Phase One IQ250 or a similar Sony design, then I think you can expect some great things from this camera. The IQ250 (see this article I wrote on the IQ250) has shown to have an amazing dynamic range and this should cross over to the 645D 2014 when it ships.
What’s key here is that Pentax ship this camera on time i.e. April of 2014. If they miss their dates and push it back then they will loose momentum and photographers will look elsewhere. I don’t think they will have any problem showing good quality images, as I don’t think this chip can take a bad picture. I also hope that Pentax steps up with their dealer support in the U.S. and possibly offers a similar program to the Phase One Value add warranty. Time will tell on this. If the price does come out at under 10K U.S, I expect that it’s possible the flood gates may be opened in the U.S. since this chip is showing to be such an excellent performer and is definitely changing the game in the world of medium format digital. One thing that Pentax does not have here in the U.S. is a strong dealer channel pushing the product to the market, and allowing demo’s for both landscape and studio shooters.

I have no idea how long these links will stay up, but hopefully they are kept in good order as they contain quite a bit of details on this new exciting MF camera.
