I bet the Pentax FF body would not be released earlier! :-( Frankly, the new lens and body should be released on the 1st of April so as to celebrate the traditional Pentax BIG day for these years! ;-D That must be really great and please delay no more, Ricoh!! :-(

The new generation of Pentax rumouriser, Mr Asahiman, strikes again! :-o
I still remember last time he told the world that the Pentax FF was coming on October the 6th! ;-)

Has this lens not yet been released? How come they tested it back to April already? :-o
Saturday, November 14, 2015
They say, "In order to meet the performance which was originally expected." And the new release time will be advised later in December. So, what has gone wrong with this lens!? :-o

To improve AF sensitivity in the dark.
Wednesday, October 14, 2015
Someone at the Chinese Xitek forum hinted that he had tested the beta unit of the FF and told the following:
1. The new machine is not 42MP.
2. The AF speed is very high.
3. There are many AF points than ever.
4. SR Super-resolution mode now works handheld.
5. The result of the handheld super-resolution mode is good and it works!
6. Overall better experience than the D810.

The "DFA" badge looks cheap IMHO, though.

They look very close, but there are minor differences, probably due to sample variation or measurement method differences.

This is what I have compared with the images got from the camerasize.com. Here we go, the Pentax FF image has been accurately resized:
Maybe it's time to check and review the old figures, there are at least six months to go! ;-p
And, the Pentax lenses I own are marked in Bold, although not all of my FF/MF Pentax lenses were tested by the Photodo, e.g., my FA31 and 77 Limiteds! :-D

V1.02 is now available for download at the Japanese Ricoh site:
1. Stability of CDAF is improved.
2. Finer sound quality setting when external microphone is connected.
3. DNG RAW may not be displayed correctly at the PC when previewed with software, bug removed.
@ The PB: http://www.photographyblog.com/reviews/pentax_k3_ii_review/
Whilst PB has been positive about the AF performance of the K-3II, our respectful PF, on the other hand, has found something opposite, see:
Quoted, "Although on paper, the Pentax K-3 II promises to bring undisclosed improvements to AF-C performance, we did not observe any evidence of faster focusing, lower latency, or quicker target re-acquisition with the K-3 II."
So, whom should we believe after all? ;-p

I think I have been for long not posting shootout test and here it is, for my old cameras! ;-)
Measurbate and discover by yourself, for all the differences! Original photos are available for viewing by clicking the "Download" option per photo under album! :-D
EXIF data is available for all photos. Pairs of test shoots were taken at almost the same time for the same scene.
Lens used for A7R is a Canon EF35mm F2 (AE and AF adapted) and a FA645 45mm F2.8 for the 645D, for almost identical FoV.
Saturday, May 30, 2015
Friday, May 29, 2015
Both are done by measurbators, but one with real-world scenes as the shooting targets and the other with test charts in a "lab":
(Tested with K-3, in Traditional Chinese)
(Tested with K-5 II)
The lens model seems to be fairly good. However, it arrives just too late, Canon and Sony had similar models many years ago, when APS-C DSLRs still shined. Nonetheless, I myself feel that the DA17-70 F4 would still be a better lens optically, because of its constant aperture but only a slightly shorter reach. For size and weight wise, the HD 16-85 is not a compact lens anyway.

Contains fix for a major bug which was introduced last time.
Saturday, May 23, 2015
It is reported that Ricoh Imaging USA has confirmed this also.
It seems that the Pentax APS-C system is dying, but the new FF system has not yet been completed and arrived, bad! :-(

Everyone got an award anyway. And, I just wonder why the K-s2 is an "advanced" DSLR whilst the D5500 is an "entry level". They are direct competitors in the same market segment and price tag range afterall!
Btw, here is an YouTube direct comparison review of the two, for those who are interested:

I have re-downloaded 15 models of the Pentax cameras that I bought over years on the list! ;-D
Tuesday, March 31, 2015
Pentax is ranked #12, the model ranking is as follows:
Where K-5 is ranked no. 1, K-3 follows. But the strange thing is that the number of items made with K-3 is zero, but it still ranks no. 2!? :-o
Tuesday, March 24, 2015
The IQ is not bad IMO. But wait, a K-s2? APS-C, not FF?? ;-D Do note the aperture values also.
The 645Z is also side-by-side compared.

Well, I believe that the last lump of plastic thing is just to keep commercial secrets by the RP whilst letting interested users to know something is really coming soon, the testing prototype or even the beta machine should be more than that, in view of the launching date which is so close.
Different non-standard colour schemes are shown. New features and functions are briefed.

My Practical Review on the DA18-135
Friday, February 13, 2015
Transcripts in English and Chinese are as follows, dropped down and translated by a Chinese Xitek Pentaxian:
First of all, thank you for publishing the news about the upcoming launch of a full-frame DSLR.
The PentaxForums.com announcement reached over 200,000 Pentax fans on Facebook and was met with very positive feedback.
Do you have any thoughts to share with the fans that eagerly await the full-frame product launch?
To tell the truth, I was relieved because many Pentax fans don’t say “It’s too late!”. I’m very glad to hear the positive comments from Pentax fans. Thank you for waiting for a long time.
What kind of users and applications will the new full-frame Pentax DSLR be aimed at? How will it stand out alongside the competition?
The first users are Pentax fans, besides it’s important to get back the Pentax users from competitors. Therefore, it’s not up to making have many strength
of Pentax.(??) Besides, it’s important to have attractive features newly which other competitors don’t have.
What do you think is the most suitable resolution for DSLRs with full-frame sensors?
Current cameras in the industry have resolution as low as 12Mp and as high as 50Mp as of this month.
I think the suitable resolution is changing. According to the sensor technology, and environment to handle the image to date(??)
Can users expect more full-frame compatible lenses to become available together with the launch of the full-frame DSLR?
We are going to develop DFA lenses as soon as possible, you can see the new lenses on the newest lenses roadmap.
Do you have plans to re-launch or update any FA-series lenses as with the 645 lineup, or will you be focusing on new designs going forward?
We are going to design new lenses basically, however, we are also going to redesign some FA lenses which have good resolution performance.
You state that the full-frame will support DA lenses via an in-body crop function.
How would lenses with 35mm image circle coverage such as the DA* 200mm f/2.8 be handled?
Will you change any existing lens designations/specifications?
你们说全幅将通过机内Crop功能来支持DA镜头。那对于那些可以覆盖35mm图像范围的镜头呢？比如DA* 200mm f/2.8，机身将如何对待这些镜头？
It’s true some DA lenses cover the full frame image circle. However, we make it priority to develop the new lenses basically, rather than to redesign the DA lenses.
Do you plan to reintroduce the aperture coupler in the Pentax full-frame body so that legacy lenses can meter without having to stop down?
I think it’s important, but it’s difficult because of the limited space.
How would you describe the response to the Pentax K-S1? Has it seen success among gadget-oriented people?
Because K-S1, we try to attract non-Pentax users mainly, in that sense, we have very nice interests, but before that, the (??) so far we couldn’t get return as we expected.
Do you have plans to improve the speed of the SAFOX auto focus for fast-paced shooting?
The AF performance of K-5 II has been improved. We are improving speed one more, and new telephoto zoom lenses, have high speed actuator and new developed algorithm, so you can you then comfortably.
The Pentax lens lineup still lacks products such as leaf shutter lenses, tilt/shift lenses, and extension tubes. Is this an area you feel important to expand?
It’s important, especially for 645 series, so, we are considering.
Why is wired tethering not possible with the Pentax K-3? Do you plan to offer this feature in the future, i.e. via Image Transmitter 2?
Many users find the speed and range of the FluCard to be insufficient.
为什么没有办法在K-3上联机拍摄？你们有计划提供这个功能么？比如通过Image Transmitter 2？许多用户发现FluCard的速度不足以支持联机拍摄。
Image Transmitter 2 is developed for 645Z, however, some K-3 users requiring us, so, therefore, we are considering with firmware upgrading.
Image Transmitter 2是为645Z开发的，不过一些K-3用户反映了这个需求，因此我们正在考虑通过固件升级的办法来解决。
As industry trends change, do you have plans to continue pursuing more consumer imaging gadgets like the Ricoh Theta based on the market response?
Of course, it’s important to expand the market(??) with new imaging gadgets.
Would it be possible to leverage the SR mechanism to increase the effective resolution of a Pentax DSLR?
We have tried to increase the effective pixels with shake reduction, but dataset is big, but image quality is not improved. So, we are now trying to improve the resolution performance, without increase the effective pixels.
Do you have any comments in response to the technical feature suggestions presented by our users?
It’s really nice to listen to the end users, because they have requests and expectations. We study carefully, and depending on the necessity of the requirement, we might consider to implement onto the firmware upgrading.
Why has Ricoh Imaging decided to launch the full-frame DSLR now?
Can you comment on how it will stand out relative to the competition?
Ok, as you know, we have a lot of K-mount series lens, as well as 645 mount, so we had valued our existing customers, and we believe with this time has matured, it’s really nice time to release full-frame for whom waiting for that.
How does the size of the Japanese market for Pentax and Ricoh cameras compare to international markets？
Frankly, the comparison of Japan market for Pentax Ricoh is larger than the one for the global market.
Has the Ricoh Imaging international market share for ILC’s increased over the course of the past two years?
Which product category has been the most successful?
As you know, the market itself has really aggressively decreasing. We are facing that trouble, but we are safer than total market trend.
Sony has been dominant in sensor manufacturing the last few years.
Are you seeing other manufacturers wanting to partner with Pentax?
Does Pentax see some advantages to partnering with other sensor manufacturers?
Selection of sensor is purely for our engineers to make our product more attractive, so we are not attaching to A name brand or B name brand, so it’s merely to what kind of performance the device provide to us.
Would you like to share any closing remarks with the community?
Yeah, both of us are really thanks for this interviews. After the launching of the full-frames, everybody is exciting. So, please be happy, until the product come into your hands.
Thanks for waiting for Pentax full-frame camera for a long time. I’m glad to …(??)
Multiple view angles and "side-by-side" against the K-3, really nice! Good job, man! :-)

So, it is somehow big, as many Pentax fanboys have complained for years for *all* 135 Full Frame bodies of other brands. So, what would they say now? :-P
Besides, just found this PS job at the Chinese Xitek forum, does the mockup feel more realistic now? ;-D
