Same site, same author, who has done many shootout tests between the two cameras recently and shared his results:-
The lens was put at f/5.6 at 50mm which could one of the possible sharpest settings of the lens.
This time, IMHO, the difference between the K-5 and K-5IIs is almost non-existent. In fact, with the extra-sharpness setting +1, the K-5 sample and crop seems to be a bit sharper, even! See this:-

Btw, do you see and like the moires? :-o
The measurbation results seem to be in line with what PhotoZone found long time ago. I now understand why Pentax Germany replied Klaus that the lens under test was "within factory specs"! :-o
If we compare further of the above against those of the original Canon EF-S 18-135 IS, the new Canon 18-135 IS STM and the Nikon 18-135 DX by the SLRGear, the Pentax results are really pathetic.
Still, I like my DA18-135, maybe the lens IQ, especially the image corners, are not good at close distance, where a test chart is usually placed.

Latest Pentax Reviews: DA18-135 and K-5 Vs 7D
Saturday, October 27, 2012
First played with a M with the 18-55 STM kit zoom for about 15 minutes and here are what I found:-
- The body is really nicely built and it feels very solid in hands. Unlike all other mirrorless bodies, the M is actually made in Japan.
- The body is thicker than the NEX but is obviously thinner than the K-01. It feels a bit heavier than my NEX-3, which is yet the lightest and most compact APS-C mirrorless body ever.
- The M does not have a built-in flash nor supports an EVF neither, which is even worse than the K-01 which has a built-in flash!
- The LCD monitor display quality is good, the touch screen is fairly (but not very) responsive.
- The AF is rather sluggish, though. The environment I tested it is fairly bright. It sometimes missed the focus when the DoF is large, say, at close distances. To focus on far object, the AF time was shorter.
- When using the AF with touch focusing, the camera seems to focus slightly faster. But I just wonder why, or my feeling was wrong. Under this mode, the camera will shoot immediately after the focus is achieved, which may not be good for this design if you want some control for when to take the picture but I understand that this is intended for the novice.
- Also, turning off the touch focus function the camera seems to focus slightly faster, too.
- The mechanical shutter action is smooth, light and quiet, better than all NEX here (I just used a NEX-7 of my friend the week before). Unlike the NEX and the K-01, I can't really hear the double shutter actuations of the M. Indeed, a light touch is important as it would cause less camera vibration caused by the first shutter actuation.
- The shutter lag of the M is long but I think it is comparable to the NEX and is a bit faster than the K-01.
- As for the operation, I haven't yet adapted to its menu system and operation interface as there are very few direct buttons and no mode dial at all. On the other hand, there is a record button at the right thumb position at the camera rear which is very handy to use (same as the NEX' design).
- I haven't tried the video function yet, maybe I shall try later.
- Still, I think the NEX-6 maybe a better package and offer all in all for that very close price range, of which the ILDC related technologies should be more mature.
Two Really Good Things of the K-01!
See what 43 Rumors report:-
So, this is a camera with a 16MP Sony sensor without an AA filter in front of the sensor, resulting in a "higher image quality" as people say.
This must be the cheapest AA-filterless body in the market then. Similar to the K-5IIs, it is in 16MP and uses a Sony sensor.
Speaking of the Amazon sales charts that 43 Rumors have pointed us to, we can see that in the ILDC chart, the best Pentax result is at #40 for the Black Q dual lenses kit. The other Pentax offers that stay in the chart are #71 for the Yellow K-01 with the DA40XS and then the Black K-01 with the DA40XS at #100, as being the last one that stays in the chart, just! :-o
As for the DSLR chart, the best Pentax result is K-5 body-only offer at #41, followed by the K-30 with DAL18-55 (non-WR) kit at #43, and then at #61 for the K-30 with DA18-135 WR kit. The more surprising thing is we can see the K1000 Pentax film body with the 50mm F2 lens is on the chart at #62 (and jump the boat?)! It seems that a lot of the old Pentax users are selling their old Pentax classic gear like this! >:-( Btw, the last Pentax thing that we can see in the chart is the White K-30 with DAL18-55 kit at #86.

Wow, this OM-D user is really clever and brilliant!
However, this tricks does NOT with any existing Pentax bodies which do not have the focus peaking feature built-in, i.e., those models without a PRIME M processor, including the K-5, K-5II/IIs and the Q. It is because the in-camera digital filters of the Pentax cameras are applied in post-editing, but not viewable at real-time in Live View.
Remark: To those particular fanboys: Whoever wants to argue again, do read the relevant Pentax user manuals and try before hand. If they don't have those Pentax cameras (which they usually don't have the gear they defend!), I would ask them to get the soft manuals online first! :-o

Well, the poster commented that the difference in sharpness is negligible in his opinion. Besides, I found that the colour rendition of the K-5 is better, once again! The K-5IIs shot is somehow greyish for the blue.

Via Post @ the Chinese Xitek Forum
I like the colour rendition of the old K-5's LCD monitor better. It looks more faithful and detailed than the new air-gapless LCD. In particular, just view the heavy blue cast of the white sky of the air-gapless mon. and that the green colours do look odd and unnatural. But yet, the outdoor visibility in the field is not differed by that much against what is officially claimed!
After all, it is really not good to run bare, for both the sensor and the LCD! :-o ;-p

Below is a snapshot of the ISO 3200 comparison pair:-
(Left: K-5, Right: K-5IIs, @ ISO 3200 - Click to Enlarge.)
It is obvious that the colour response of the K-5 is more favourable. The colours produced by the K-5IIs is dull and less pure. As for the details and sharpness, I even found that the above K-5 picture is better! The noise of both cameras are very close and comparable, nonetheless.
Wednesday, October 24, 2012
Test shots were made with the same FA31 Limited lens under the same lighting and test condition from f/1.8 to f/11 with an addition test shot at f/5.6 with the "extra sharpness" setting:-
K-5: http://pentax.briefing-paper.com/1121 (in Japanese)
K-5IIs: http://pentax.briefing-paper.com/1864 (in Japanese)
In particular, the following is the side-by-side f/5.6 pair of the comparison shots:-
(Above: Left: K-5 100% Crop at f/5.6; Right: K-5IIs 100% Crop at f/5.6; Normal Sharpness; Lens Used: FA 31mm F1.8 Limited - Click to Enlarge.)
Btw, with the removal of the integral AA+IR filter of the original K-5, the K-5IIs seems to produce colder picture than the K-5, with a purple tint and tendency.
In fact, the amounts of details of the two cameras are close enough, whilst the K-5IIs pics look a bit "sharper" and "harder" on edges. The fortunate thing is that the focusing accuracy of both cameras is good enough. The K-5 pictures are yet a bit brighter, though, despite that a +1EV exposure compensation was applied for both cameras. Last but not least, the micro-contrast of the K-5 shots seems to be somehow better.
See this Flickr page:-

K-5II/IIs: Central Cross AF Sensor Will be Disabled with Most DA Zoom Lenses, and even Some DA Limited Primes!
(Source: Pentax Japan K-5II/s page, Credit: Blog reader "jaad75".)
Look at the above official diagram and illustration. For the "new" K-5II and K-5IIs, the first thing is that only the central AF point is equipped with the f/2.8 sensor, for the horizontal one. That f/2.8 sensor is unique for being the one and only one f/2.8 AF sensor that the camera has. However, this sensor will NOT work with any lens that is slower than f/2.8! Under such case, the horizontal AF sensor will have no function! That means that the central cross sensor will simply become only a vertical linear sensor with most zoom lenses, except for those very few f/2.8 ones. Moreover, even those slower primes are affected, e.g., the DA21 F3.2 Limited and the DA15 F4 Limited!
At the end of the day, I would rather keep my K-5 and do the AF fine adjustment in a precise way instead if I have to sacrifice like that, which is even more problematic IMHO! :-o
After all, my last prediction is correct! Pentax is yet to do thing in the easiest but cheapest way, without taking the real drawback caused as a result into account! >:-|

Btw, the K-01 and the previous disclosed new lenses are not mentioned anywhere and will not be displayed of course. It seems that Pentax Ricoh has firmly decided to abort the "line" and will continue to execute their that decision. That is really sad after all! >:-(

Read this lengthy incompatibility EF lens list with the EOS M (when the EF adaptor is added) and I am shocked!
Even the lens is compatible, the AF speed of the new Canon mirrorless is just terribly sloooow, even when it is worked with the latest Canon EF-M STM lenses, which are specifically designed for the EOS M! :-o
Oh, what a poor performance it is! Compare that against what the K-01 can do and it is different as day and night!
Furthermore, the K-01 guarantees full compatibility with any of the original Pentax K-mount AF lenses.
After all, the above two good things should be praised! :-)
Well, here is the PQI Air Card in SD format, it should be compatible with all the latest Pentax DSLRs and the Q inclusive, as officially tested and listed.

Last time I have searched for the whole document, there is no information of any for mentioning about the f/2.8 AF sensor for this "new" camera. So, the mystery about its layout and compatibility / usability with different lenses are yet unknown!

AF tests with the new firmware is starting from 04:55 and before that is with fw version 1.00. It is once confirmed that the new firmware provides obviously better performance with faster AF speed. The improvement is particularly obvious with the longer (focal) lens, i.e., the DA*300 in this test.
Update: One more exact comparison with the DFA100WR also, by another Japanese K-01 user, before Vs after:-

By What Blog is This?
Via 1001 Noisy Cameras.
Assuming the battery power levels were the same, the new firmware does significant improve the AF speed of the K-01. However, the CDAF still need to turn the lens to-and-fro so as to search for the focus but did never know which direction to turn first at the beginning. I believe that if Pentax will be able to get the new Sony sensor with PMAF sensor built-in, e.g., like the one used in the NEX-5R, this search should not be even required in most cases and hence the AF performance could be twice faster! (But provided that if Pentax can get any new sensor! >:-()

See this article:-
(Newly discovered website introduced by the 1001 Noisy Cameras.)
Well, we all know, DSLRs have mirror slap as well as the shutter movement that cause camera shakes right before the exposure and hence image blur. But then mirrorlesses have yet another shutter movement in lieu of the mirror slap, so the final results obtained could not be better! :-o
Btw, Sony has its electronic first curtain shutter by now in their latest NEX and A series bodies, I think it will decrease the shake effect and should improve shutter lag. However, the side-effect of it in particular to any possible impact on the IQ is yet unknown, if any. (I do not believe that it could be a perfect design, as for most of the time everything is just a trade-off!)

The K-01 is not completely dead, Pentax has provided a new firmware for it today!
It is said that the AF performance and compatibility with SD cards are improved as well as the new firmware is generally debugged. If you are a K-01 user, just follow the download link in the above page to get and install the new firmware.
Well, this is a gun camera:-
It was modified from a real gun by the Japanese traffic police back to 1954, the purpose of it was to shoot with one hand and steadily! Clever design, I have to say.
But then there was a real gun which looked like a camera by the CIA in 1966. Well, it was modified from an Asahi Pentax Reflex! Oh yes, it was the big glorious days of Pentax which Canon and Nikon only knew to follow!!
Don't press the shutter release button of this "camera" too causally, it would really make a *killer* shot! :-o
Now, in 2012, what does the meaning of the first gun camera? Back to the 90s and early 2000s, there were such cannon/gun looking film and digital cameras:-
Above: Sony F717, 2002, Picture Source Here.
Above: Ricoh Mirai, 1988, Picture Source Here.
Above: Olympus AZ-4, 1989, Ricoh Mirai Twin, Picture Source Here.
And finally here is the Pentax Optio MX/MX4, of which I purchased my "MX" back to 2004. I must say its ergonomics is excellent and is very suitable for prolonged time video shooting. Whilst the user can hold very steadily for both video and still picture shooting, the camera can also be operated with one hand basically. Well, the Optio MXs had a flipped LCD with great freedom for its movement, which is really great!
Above: Pentax Optio MX, 2004, Pictures' Source Here
Now, it is heard that Pentax Ricoh is going to abort the K-01 line and is not developing it further. That is sad as they should make the K-01 in such form factor and design, which they should be able to do. That will surely hide the long flange distance of the K-mount and adding an EVF and include back a flipped monitor with a similar design of the MX', that will be a clear winner, I am almost certain!
We all know that the K-01 is by now the "best" video shooting Pentax body in the line. However, I do think that it is just not good enough. Change the form and shape of it, add also a stereo microphone! Then it could rival the Sony NEX VG900, even it is a Full Frame, just because this proposed Pentax mirrorless can be sold far cheaper for its much lower cost. Also, if there will be such a cannon K-02, all the R&D efforts paid by Hoya will not be wasted, and possibly it will form a new line of Pentax K-mount APS-C mirrorless that could finally succeed, as it is being unique in the market but yet have a great usability and being very practical to use!
Furthermore, they should buy the new NEX-5R 16M sensor from Sony, which will do PMAF on sensor to further enhance the AF performance, especially during video recording. The last time I tried, the CDAF of the K-01 was not that bad indeed. In fact, I am much impressed with the CDAF performance of the latest Pentax cameras which is better than any Canon DSLR and close to my NEX IMHO. And who says the K-01 CDAF is meaningless? I am sure that it is more accurate with all different K-mount lenses than all those Pentax DSLRs after all, the K-5II/s inclusive! The CDAF is WYSIWYG, what thing else can be more accurate?
Don't you guys agree with me this time?!

Thanks to Blog reader "qwe" for his alert, we have the latest Pentax Ricoh interview by the Japanese DC Watch, as follows:-
The above is in Japanese, you can read also the machine-translated English pages by Excite here and Google here.
The interview has just been published today, it seems that the tone of Pentax Ricoh has changed considerably since the last series of Photokina interviews (by IR, PF and etc.) a few weeks ago. This time, the interviewee is the head of (product?) development division of the Pentax Ricoh HQs, Mr. Toshiyuki Kitazawa:-
(Mr. Toshiyuki Kitazawa, Head of the Development Division of Pentax Ricoh Company Japan.)
So, I would like to summarise the more important things and key messages contained from my best understanding:-
1.The aspiration of a Full Frame camera and body for even better image quality by the users is understood.
2. The trend of traditional DSLRs (with mirrors) for being go up to the Full Frame sensor size and with lower prices is recognised.
3. They have started to develop a Full Frame digital system. However, the current faced problem for not marketing a FF system right now is the lack of a complete FF lens lineup, which is yet to be developed.
4. They are continuing to liaise with sensor manufacturers and try to source a suitable sensor unit for the new body.
5. He believes that the APS-C format still has its advantages, for its compactness and flexibility, and which the image quality is already not bad. As such, the development of APS-C and FF will be carried out in parallel.
6. A Pentax FF would come true within the fiscal year of 2013/14, but still maybe later.
7. The advantage of a camera body without an AA filter is for its highest possible resolution out of the sensor but with trade-offs of possible moire and false colours and noise, which is less likely to happen with the higher pixel density of model sensors.
8. Pentax has planned to make more AA-filterless camera bodies in the future, with new technologies being developed and involved.
9. The Q system will continue its development as an unique product line of its own.
I like the style of this Japanese Pentax Ricoh guy than the previous PR sales guys at the Photokina. I do have a far better impression on the way he is talking things in a far more practical way. He has touched on something technical but it is not too difficult. All in all, I think his statements are concise, clear, direct and fairly honest plus humble enough of himself, on what are being asked! Good! :-D Of course, at the end of the day, we don't have to agree with what he says and the Pentax plans as told, nonetheless!
Update (10-11): I have just checked that Mr. Toshiyuki Kitazawa is an engineer by himself who owns quite some patents related to cameras over years. See this profile of his for details. Now I know why I have had a good impression on him by feeling at the beginning! ;-) I don't like those sales guys btw, who often have too much crappy sales talks for most of the time but without knowing better for the technical stuff behind! >:-( They will never tell you something concrete also, neither, at the end of the day!
Yet Another Pentax Full Frame Rumour
(Click to Enlarge.)
This should be the first K-5IIs sample that posted online, via a forum post at Photo Malaysia here.
In the same thread, we can see a pair of comparison pictures on the K-5II and K-5IIs sensors and their different appearances:-
Via this post here, in the same discussion thread.
Well, I like the appearance of the K-5II sensor better, it looks clearer and more transparent after all.
Btw, if you wish to see the official comparison illustrations by the PR about the difference between the K-5 and K-5IIs, read the opening post of the above thread here. The diagrams were displayed at Photokina as exhibits.
Everything has no proof of any and rumour is rumour. So, just believe it or not! Btw, these Pentax FF rumours have been with us for years, which seems to be a dream that never vanishes amongst we Pentaxians, maybe until one day a FF Pentax body really comes! ;-)
This time the samples seem to be look better than those of the last review at Optyczne.pl. The measurbation results seem to be better than what SLRGear measured and found also.
However, I discovered an obvious quality issue (minor or not) from the outside appearance of the lens under test at my first glance. That is, the white painting of the "focusing" mark (but which points to *nothing* for this lens design!) spilled over in the front and too much paint was applied at that position in the factory, resulting in a rather uneven white line. Indeed, this little error causes the lens looks cheaper which gives an even poorer impression on the build quality and QC of the lens! >:-o

The K-5II and IIs will be on sales in Japan on October 19 and the official initial (Japanese) selling prices are published.
So, I would like to see what's your buying intention of these new models. Are you intended to buy?
Thanks to Blog reader "flomatix" for his email alert, I have noticed this:-
Which is supposed to be an online survey created and conducted by Pentax Ricoh, although it is not clearly stated anywhere in the survey, except the PR logo.
I have participated in the survey anyway and you are encouraged to do so as well. But since the identity of the survey creator cannot be verified, I suggest not to put in too much personal information especially those sensitive ones at the end of the survey as such. Also, I think they focused too much about "making money" with the Pentax gear, which I bet most of we Pentax users are just amateurs whom take photos as hobby and buy gear solely for hobby and so their thinking had been in the wrong direction right from the beginning! :-(
Btw, I conducted a brief poll around the Photokina which in principle was asking something similar to some of their questions, but in a more concise and direct way, of course. You can still make your vote in the following poll of mine if not yet:-
That's All What Pentax has Shown us at Photokina! What Will You Do Next?

(in Japanese, Excite English Translation Here.)
Via Photo Rumors.
This new patent has just been published yesterday. Do note that it is specified that the "Image Height Y = 21.64mm", which simply tells that it is not a 135 Full Frame lens for the image circle, despite that the focal range is really common for many of those Full Frame F2.8 tele-zoom lenses made by others. The slightly larger image circle than APS-C will allow the in-body SR to work and also that the sweet spot of the optic could be utilised.
Btw, it is yet another piece of evidence to hint that a Pentax Full Frame body and system is not going to happen in the foreseeable near future, as Pentax Ricoh is still putting much effort and resource in the development of those hopeless APS-C stuff! >:-(
Updated: Thanks to the reminder by someone and I have checked again the performance chart diagrams as published (example here), I think it is actually a Full Frame lens! The Y is simply the distance that is measured from the optical centre! So, it is just a Full Frame lens! Well, the dark cloud has suddenly disappeared and been turned to bright light then! ;-D Sorry for the confusion anyway and I am really glad that I have been wrong! Still, the new lens and design is yet 10cm longer than the old FA*80-200/2.8, which *also* has an internal zooming mechanism and is much shorter and "compact" enough.
Besides, this new lens should include an in-lens IS (or SR in Pentax' terminology), as the image circle just fits and there is no spare space for the body SR anymore.
And the following are posted by the same person, which are Pentax and K-30 related:-
