The Df is the best only because nobody has run tests of the K-1 yet.

I wish!

A 100MP sound interesting but what does it really equate to. How big of a photo are you expecting to print?

Dynamic range and iso performance?.....isn't that what people pay for? The best camera for ISO is still the Df.....and it is only a FF camera at 16MP. Does that make any sense given it's sensor size? Can't someone provide a MF sensor with killer DR and ISO?
I don't know to what your refer exactly (DxOmark ? ) but the 645Z sensor is already better than the Df one, for both DR and ISO. DxO showed up briefly before erasing very measures of the 645Z on their site (I wonder why...). I own a Df and a 645Z, and there is not really any comparison on performances.

Well, the biggest issue will be...

What about lenses? They need to be renewal to cover 100mp sensor. I don't know the pixel pitch but FA lenses are quite old for 100mp sensor. Pentax should announce some new 645 DFA lenses.

Well, if it may be a clue, they have given up on replacing the DA 25mm, but they have launched a DFA 35mm recently... Maybe they'll continue to clean up the line ?
And regarding pixel pitch, you can make the check yourself : 51MP on 33x44mm vs 100MP on 54x40, the difference is quite low... so if an "old" lens works on the sensor of 645Z, you can think that it will be OK on the center of the larger sensor. But for the corners of older lenses, this is a question.

DFA 35mm is almost same with FA 35mm. The optics didn't changed at all. We'll see if FA and DFA support 100mp.

The pixel pitch of the 100 Mp sensor is 4,62 micron. Almost the same as K-1 (4,87 micron) and D810. If you put the 645 lens on this shift adapter and D810 you could examine the field of view at almost the same pixel pitch to get an impression of the resolution of various 645 lenses.

Edit: Or this shift adapter from 645 lens to K mount body.

That's 'full frame' 645, just like the fancy Phase One....

Resolution isn't the only thing - I'm after the DoF characteristics of the larger sensor. Bring it on.

Think i will stop posting stuff. Seems like people think i have confirmed a new 645..I haven't. I said they have a new sensor they CAN use in a camera.

I will copy my post from Facebook here:

"Regarding my post earlier about the 100mp sensor from Sony: I have never said/confirmed that Pentax is releasing a new 645 with that sensor. I only said I'm told they have signed a deal around a sensor they potentially can use in a camera. Ricoh (Japan) is not happy, since someone has told them i have confirmed this or that, i have not. Every sayings about which camera they can (not will) use it in, are rumours. People are too fast to make their own conclusions, so from now on i will be more careful around snippets i share. So, in the time to come now, let us talk about things that ARE coming soon; The mighty K-1! Have a nice day all!!

That's too bad, kenspo, we will miss you. Is there a close relative to inform of your impending departure from this life?
