So, is the sensor cat officially out of the bag? Or do we still need to tally up and weigh the credibility of various reports that the sensor is 24, 36, or 42 MP? I wish someone who knows for sure would at least give a wink or something, about this 36 MP number.
Either way, let the analyzing begin!
The original Sony 36 MP sensor was a bit noisier and generally *slightly* inferior to the Nikon D800e sensor, although a tad sharper due to the true lack of an AA filter instead of the D800e's "cancelled" AA filter. In the real world, you'd probably never tell the difference.
All in all though, from an astro-landscape perspective I'd be disappointed in the use of that exact sensor, (if it received no processing upgrades / changes whatsoever from Pentax) considering how much better the Nikon D810 sensor is at both high ISO and long exposures, or the high ISO / long exposure capabilities of other sensors like the D750 and Sony A7R II.
The "next" Sony 36 MP sensor, seen in the D810 and D810A, offers a whole new base ISO of 64, and especially in the D810A the high ISO performance is pretty good, on par with the D750 in some ways and more useful in other ways.
TLDR; generally speaking I strongly hope that 1.) Pentax is receiving the newest 36 MP sensor possible, and not some warehouse leftovers from the D800 / D800e era, and 2.) Pentax is able to offer an equal or greater ADC processor that delivers a final result as good as the current champions at full-frame high ISO work.
Then again, I understand not everybody is interested in astro-landscape work with this camera. I do hope that no other compromises are made. I think we can all collectively hope that this sensor is as much of a younger sibling to the 645Z as the laws of physics will allow.
