But then there still is not Pentax 14-24.... so how's that going to work? By 24mm, they're practically identical.
There's a line on a lens roadmap labeled DA Wide zoom...

Right there above D FA Standard zoom and D FA Large diameter wide zoom.

It looks to be about 12-28...

Might well be an upgraded DA 12-24. It already performs extremely well optically, add DC focusing, weather sealing and HD coatings and you've got a highly capable ASP-C UWA.

On the other hand, a decent, but very affordable UWA along the lines of the Canon 10-18 f/4.5-5.6 would make for a very tempting option for beginners and those who don't need an UWA that often and don't want to spend a lot on it.

Several posts have been removed that were NOT pertinent to the subject posted and definitely were not about Pentax News and Rumors. Please keep on track guys.
So, now, the photo associated with this thread on the "Pentax News and Rumors" page is not actually in the thread. Is there some way to get the rodent off that also??

Which would be the Tokina 12-28/4.

I do not need 36MPIX in one frame, usable in ISO400-800... If I need panorama in 36Mpix-360Mpix, I'll due this with few shoots, using only best optical part of frame.
For my printed works in 90cmx60cm 16Mpix sensor is big enough. Even, when i printing larger than 1m prints, i know, how to make shot and how to edit, to get good Quality.
Pixels - not most important thing in camera.
The D810 seems to be the among the best if not the best at many of those things, as far as i can tell. it's got the best Dynamic Range for landscape of any camera on the planet. And the A7r is right up there in low light performance. Those small pixels don't seem to affect them much. You've been reading too much anecdotal evidence.

I can see I caused offence and that wasn't my intention.

I'll delete it.

If Pentax really will use 36Mpix CMOS sensor in new FF, I'll say "good bye, Pentax", and buy some other brand FF with NO MORE, than 20Mpix.
Note that the Pentax 36MP output is probably going to be optional/adjustable - eg look at the Nikon D810 image size options:

36MP FX (35.9 x 24.0 mm).
7,360 4,912 pixels (L, 36MP), 5,520 3,680 (M, 20MP), 3,680 2,456 (S, 9MP).

Not to mention the use of various crop modes:

5:4 crop
30 x 24 mm.
6,144 4,912 pixels (L, 30MP), 4,608 3,680 (M), 3,072 2,456 (S).

1.2x crop
30.0 x 19.9 mm.
6,144 4,080 pixels (L, 25MP), 4,608 3,056 (M), 3,072 2,040 (S).

DX crop mode
23.4 x 15.6 mm.
4,800 3,200 pixels (L, 15.4MP), 3,600 2,400 (M), 2,400 1,600 (S).

Much the same with for eg the Sony A7R.

So the 36MP is there if you need it, but you don't have to shoot with 36MP all the time.

I assume those crop modes (L, M, S) produce a smaller RAW file? Or are those just for the jpgs?

They produce smaller RAW's since they use a reduced area at the centre of the image sensor to record the photograph, according to the Nikon manual..

If I understand correctly, gedasst's concern relates to pixel density on the sensor, which is what affects image quality, and these crop modes don't affect that.

Aha. True - the sensor pixel density will be the same even with the various crop options.

But 36MP is not much to fear in terms of IQ generally - normalized down to 8MP (DxOMark style ...), higher MP and greater pixel density for most purposes don't harm image quality.

Plus 45% of megapixels are lost due to lens or sensor defects anyway, so the more MP you have to start with, the better

Thanks. I hope Pentax implements something similar. There are times I would love all the pixels in a 36mp (or 42mp) image, but for a lot of my work I down size the image to about 12mp anyway so a smaller RAW would be nice.

As a user of the 36 MP sensor, I can attest to its greatness. I don't know where people get the notion that it's noisier than the K-5 (which I have, too). It's not and the dynamic range is excellent, too.

@ gedasst : i suggest you take 10 minutes to read this blog, posted yesterday by one of our members, before changing your mind on sensor resolution :
