FF sensor rumors
The size of the FF sensor is fixed. It's not elastic. A 23.7mm x 15.7mm crop out of that is also fixed. It's as simple as cutting a 23.7mm x 15.7mm hole in a 36x24mm film frame. There's only one answer and only one way to do it :lol: There might be a slight adjustment in the APS-C size to fit in...

:lol: When it finally comes out, I wonder how many pages the 'FF Cropped Mode vs K3 Comparative Image Analysis ' forum thread will run to ....? :wink: And 3 of the pages will be argument over whether you need to own both a FF and a K3 in order to be able to see the differences !!:shock: Can't fin...

FF sensor rumors
We don't yet know how a lens is mounted on the FF (ie. dimension from the rear element / lens mount to the sensor) so for simplicity if we consider the reduction in sensor coverage when the 1.5 x crop factor is applied (as a reciprocal) we should be able to calculate the number of photosites utilis...

FF sensor rumors
It's been confirmed by a reliable source that the FF will have a NEW sensor and be less than 46MP..... So probably between 36 and 46MP. It may well be released later than originally stated. --

FF sensor rumors
It may well be released later than originally stated Two NYC mega-sellers, and also retail locations throughout Asia have stated the same exact thing. They know of release dates at least six to nine months in advance. Nothing has shown that ANY Pentax full-frame will be making release this year. ...

FF sensor rumors
pentax has the option of moving the sensor forwards and backwards during exposure to adjust focus for different wavelengths of light and merging the data to remove aberrations and increase sharpness for every lens ever made... just an idea... I dunno

FF sensor rumors
It's my understanding that no one moves the sensor in/out towards the lens, as that directly impacts on the focus point of the shot. Agree with the comments above about the cost of FF cameras. It will only drop as more manufacturers start using it. Presently 3 Canon, Nikon and Sony, but soon Pe...

FF sensor rumors
It's my understanding that no one moves the sensor in/out towards the lens, as that directly impacts on the focus point of the shot. Contax used this system on their only AF film SLR, the RX - probably because users having bought a collection of excellent (and expensive) Zeiss glass, wouldn't want t...

FF sensor rumors
I'm suggesting the sensor could be used to make a precise focus for each colour and merge the data to eliminate aberrations... ;) Oh right, got you now.

FF sensor rumors
Nothing has changed in this forum. 50% of members think FF or similar is worth then what they have now, 25% don't give a damn and 25 looking forward to using a FF with all the advantages and possible disadvantages it may have. I am one of the FF enthusiasts. Pentax fell behind, not only beca...

I won £25 on the lottery last night - perhaps I should change my view of ff and use this to start saving for one :twisted:

pixel shift tests come back very positive
I hope this does filter down to the existing models. How? Via a firmware patch? Doubt that's even possible.. Even if it was, it would be unlikely that Pentax would want to interfere with sales of the K-3II. Obviously depends on how it's done. If it's using the sensor shift, and nothing else, th...
