Well, Pentax K-1 is the second best and the rebadged DFA15-30 is the only worst! :-o Btw, where are the originally designed Pentax lenses? Any prime?! :-(

1. Red-Lighted LCD Monitor Display Function
The PENTAX K-1 provides a red-lighted LCD monitor display function, which prevents the pupils of the photographer's eyes from constricting after they have become accustomed to a dark environment during astrophotography.
2. Bulb Timer Function
The bulb timer function comes in handy when photographing celestial bodies or fireworks. The PENTAX K-1 allows the photographer to expand the exposure time up to 20 minutes in Bulb mode.
During slow shutter speeds the PENTAX K-1 features white dot noise reduction processsing.*
Overall Improved stability for general performance.
* When Slow Shutter Speed NR is OFF and JPEG image.
It seems that Ricoh is reading my Blog, now there is a new version of the Image Sync, which can be updated at the Google Play, for Android only. The official website has not yet been updated, though. (Edit: The official website has just been updated and it indicates that the update is only available for Android only.)
Newly added feature on version 1.1.2
･Android 6.0.1 support
･Connection performance improved.
1.View and Copy Images
You can view images taken with your camera and copy them to your mobile device.
You can also upload them to SNS sites.
You can monitor the live view image on your mobile device. Various camera operations including EV compensation and shutter release are possible from a mobile device.
I will try and see if it improves.

It's just a Piece of Shit! The Wi-Fi function of the K-1 is virtually useless with such rubbish App and software but yet the development of the App seems halted. So, what did Ricoh want?! :-(

The default LCD display settings produce too bright colours and it has a blue cast. I therefore corrected it with the following settings, after checking against my carefully calibrated professional monitor, which is calibrated internally with an external colourimeter.
I checked two units of the K-1 and found that they are more or less the same and the above settings work. See if it would work for you and produce better and more accurate results! :-)

Good article! Btw, I found that most of my FA primes have a precise infinity hard stop at the infinity mark of the lenses when mounted on my K-1 and I am pleased.

Now it can save image under individual image view. But yet I still hope that it can save the downsized image from that preview, the resolution is simply enough for most mobile applications and sharing purpose.

The above news report is in Traditional Chinese. It writes about the Sony sensor factory at Kumamoto was seriously damaged by the earthquake and affected much the production and hence the supply.

Below is the 200% centre crops without PSR and with. In-camera JPEG pics with firmware V1.10. Lens used is FA43 Limited at f/11, exposure 30s, ISO 100, shot with 2 sec self-timer enabled plus cable shutter release. Mirror lock up was disabled despite user manual said that it could be engaged. :-(
For the resolution difference but the artifacts, I blog, you decide. :-)

Lens correction functions on distortion and vignetting, which are supported by the K-1 for the FA28, are disabled whilst for the DA35, it is not supported for any lens correction function in the FF mode of the K-1.
Well, how suitable are these lenses on the K-1 FF? Any how do they differ? I blog, you decide! :-)

The ergonomics of the K-1 is superb. It feels very comfortable to hold in hands and feels very solid and balanced. The overall build of the K-1 is very good, but the camera top feels a bit plasticky and hollow.
AF is really accurate, but hit rate is not 100%, sometime it missed, especially when focusing in a hurry or under low light. But when it hits, it is really accurate. Tried the three FA Limited wide opened, no problem. Tried several other A, FA, FA*, DA and DA* primes, they all focused accurately wide opened. The K-1 probably is the most accurate Pentax AFSLR ever made, since the MZ-S. I really like it! :-)
Focusing is faster and quieter than before. But the speed is not particularly fast when it is compared to other FF bodies of Canon and Nikon. Forget about focus tracking with multiple AF points for moving objects, the points are still not enough and are too much centred. There is still some room for improvement.
Exposure accuracy is good, probably maybe a bit bright for its tendency, especially with film glass. Seems a bit more accurate with digital lenses. Nonetheless, the EV compensation is always there. It is quite easy to use with the quick function dial. I set it to +/- by default. Or, one can customise the e-dials to directly control the EV compensation.
Resolution of the images from K-1 is really superb. The per pixel sharpness is better than the Canon and Sony FF bodies that I have, even with the same lenses put on them. That's only my own subjective impression, though and no scientific measurbation has yet been made, because I am now busy with shooting with a good camera, instead of doing endless measurbation tests for faulty cameras.
Colour rendition is contemporary, which is now very Canon alike. It do taste very CMOS, the AWB is very white, maybe too white IMO than one would like to preserve the atmosphere even under the warm sunlight. But K-1 do really "catch up" with the game. ;-) I found it works best in the Natural mode, with the Saturation turned up one step.
Dynamic range is good, better than the Canon's. Noise is acceptable up to ISO 3200 and beyond that, use it unless it must be.
Lens correction now works very well. It is fast and there is no more delay as in older models, even with all the four corrected function enabled. Supported all DFA digital and FA* film lenses. DA lenses are supported in crop mode. Lens correction does not work in FF mode for DA lenses, even if they are actually FF compatible. On the other hand, for supported FF lenses, lens correction does work even when crop mode is selected.
Liveview operation is good, the liveview image will change according to the FF or crop mode selected (and of course). The LV AF is fast but unfortunate insensitive. It often missed focus with lower contrast, even under bright light situations outdoor.
There is nothing special for the video recording (movie) mode. And there is no live AF under movie mode. AF can be remeasured upon pressing of the AF button on demand by the user. It is not possible to capture any still photo during video recording.
The super articulated monitor is sturdy and easy to use, better than imagined before. Most importantly, the closed position is well aligned.
Mirror action is crisp but yet gentle, resemble the old feel of the MZ-S film flagship. The *ist D had similar feel in the mirror but however its movement is obvious too slow. Now the K-1's is quite good but I still hope that it could move faster anyway.
Viewfinder clarity is not as good as my Canon 5DIII which is brighter and clearer to see than the K-1, despite both have an overlaid LCD information display on the finder frame.
The electronic level indication is now very easy to see and follow. It is sensitive and accurate provided that you got a good copy. My first copy has good accuracy for the horizontal sensor but the vertical sensor is a little bit off.
GPS is sensitive and accurate and is very easy to turn on and off, with the dedicated button. WiFi is also easy to on and off with the special function dial. The red and blue LED indicators is a good design. However, the Ricoh Image Sync App is just a piece of junk, undoubtedly. It is difficult to use, with limited features and its operations are completely nonsense, even for the basic functions of browsing photos and for downloading.

MTF curves are measured at wide opened and at f/8 across the frame. Vignetting is also measured.
