There must surely come a time, and not too long hence, when even the best lenses will not provide sufficient resolution for more and more densely-packed sensors. Pentax has already replaced one lens - the original 18-55 - because it couldn't cope with the K20D's sensor. I would guess that at 18M...

18.2-19.2 mega pixals on an APS-C sensor will be the last nail in the coffin for Pentax. Unless they have an ex Canikon noise reduction engineer lined up for a job they will flunk big time. I would much rather see an APS-C sensor (or FF) with a pixel density of 1.5 to 2 for either size. I base th...

:PWe have the 'Megapixel race' We have the "High ISO race' What I would really like the next big technological advancement to be is a 'Dynamic Range race.' If Pentax could concentrate on that one instead of following the herd, it could make things very interesting! I couldn't agree more and it...

I actually believe that it would be very sensible for Pentax to produce two variants of the same body, one aimed at low noise (K-x sensor?) and the other aimed at very high resolution (Ben's 19MP suggestion) similar to the Nikon D3/D3x concept. A K-8 and K-8x maybe? I think that there would be su...

With all the post processing that can be done these days the thing I would like to see on the next Pentax is a square format sensor then a simple crop would save a lot of twisting and turning with the camera. There are all the other things as well but surely that would be a simple modification to a ...

I've just sold my 645 to SRS which of course was 3 x 4. however think of the other M.F cameras that were 21/4" x 21/4" = 6 x 6cm. which many Pros. used and still do in 6 x 6 Digital. So far I haven't heard of a 6 x 7 or 6 x 8 or 6 x 9 Digital. Surely the shape of the camera could remain the same but...

Years ago a wedding photographer told me that he used a 6x6 Mamiya TLR film camera, so that he could take portraits and groups without having to turn his camera 90 degrees. He just cropped in processing. I suppose that a square sensor would be used in the same way and photographers would no longer ...

well - recently a lot uf users turned round and found the K7 good indeed - how strange ... even they consider the K-x as far better, at least about AF and noise reduction; so some bright minds - in France - suggest that Pentax puts Sony 14 Mo sensor + an improved software to upgrade the K7 performa...

I have no idea which sensor my camera has and in this world of multi national cross border co-operation it could have been as you suggest. My comments on the noise levels comes from the review on the 'dpreview' website. But the 'Amatuer Photographer' magazine test found the noise to be better th...

I have no idea which sensor my camera has and in this world of multi national cross border co-operation it could have been as you suggest. Most of them are Sony besides the K20D and the K7, many sensors Pentax use can also be found in Nikon cameras and Sony so they all preform basicly the same.

...or do something similar to the Phase One backs. Super high resolution for "normal" ISO range, and use clever "bucketing" of the photosites to increase the ISO & quality while sacrificing pixels. (Though their method of using diagonally arranged G pixels is obviously patented) Who knows... :D...

Pixel grouping would be nice for low light photoghraphy. My GF has a Fuji F200EXR compact and it normally works as a 12MP sensor but if you switch to the 'EXR' modes it becomes a 6MP sensor with higher sensitivity and lower noise levels. I wonder if you can get better results when you apply noise r...

I think you will find that the Fuji sensor has a different layout of the RGB light sensitive pixels to a normal dslr. It isn't as simple as just using two adjacent pixels to represent one in the image because of the ditribution of red, green and blue sensitive sites on the array. If it were, then ...

Here is some info on how the EXR CCD sensor works. The layout is indeed different.

Have Pentax shot themselves in the foot?
Just a thought but couldn't it not be that Sony stop producing the sensor that was in the KM, it was after all a pretty old one with his 3 years?
