If I use a 50mm ƒ1.4 lens on APS-C I can only get a little bit of blur in the background.
If I use a 50mm ƒ1.4 lens on FF I can get a nice and creamy soft background.
I'd have to use a 85mm ƒ1.4 lens on APS-C to get a similar effect but then I'd have to stand farther back to get the whole person in the frame
So just saying that there are plenty of valid reasons why people may want FF.
Yes this is one true reason for sure.
And AF works more better when have more tele like FF 45mm than APS-C 30mm
And FF can use about double ISO with same noise as APS-C
And FF have bigger, more clear and brighter viewfinder
And APS-C ultrawide is only FF wide and that mean better images at ultrawide end
And FF bigger sensor means more sharpnes and less noise in photos
And FF means also more pixels
But are we ready to pay much more to get FF body than we pay now for great aps-c K5...like over 2x more...i am not...1.5x or so would be my limit. So Pentax should make cheaper than Canon and Nikon cheapest FF.
