Well I would even prefer a large 4/3th sensor at the size of 28x21mm with 12 megapixel wiht large pixels (that is the size of the new Canon 1Dx) to get excellent hi-iso performance. So main goal is better hi-iso performance for me and keeping some crop to benefit with when using telelenses. And I guess that a lot of other things get better with it.

Well from my lensset only 14mm and 21mm would have to go. The rest is good to use. For my sigma I'm not to shure it will performe well enough on a FF.

for everyone except Ron this is a FF thread, for Ron it's an APSH thread
16mp h should out resolve c and provide closer to the true FOV on ff lenses. should be better noise wise as well. I doubt it will ever happen though despite the new Kodak sensor being made. It is the biggest you can make without complex tech like FF requires so there is a good arguement for it
You hit the nail
Originally posted by gazonk Almost... you'll need a 36 MP FF camera will give a 1.5 crop area of 16MP - but isn't 36MP exactly what rumors say about the new Sony FF sensors? A cool feature would be to implement some fancy mask in the viewfinder (lcd overlay?) which crops each DA lens to its individually recommended maximum image circle.
Maybe they are even the same wafer cuts as current K-5 is?
Originally posted by eddie1960 Sony is rumoured to have 2 new Ff sensors in the pipeline a 24mp and a 36mp.
From these choices I would vote for the 24 megapixel sensor.
Originally posted by Spag I know some DA lenses are FF compatible therefore most of (if not quasi all) DA lenses should work on APS-H, but the border quality will probably be very low anyway.
Well I guess that from my lenses the sigma 70-200 won't be a winner in the edges of FF. My other lenses would need more stopped down I guess to get better edge performance. Probably the DA 40mm/f2.8 Ltd. would be the best performer wide open. One off the reasons why I would want an APS-H and after we all bought a Full Frame camera we will all know that that APS-H was a smart thing to do.
Still in favor for having a body like K-5 with integrated grip to give room to all electronics and have a nice and comfortable camera to hold in our hands.
