Yes it was a bit of a sweeping statement but seeing Pentax being criticized for not going full frame with the K3 annoyed me. Reminded me of the marketing numbers games that went on with HiFi.
My comments where about the raw images as manufacturers can perform minor miracles with their in camera processing software. An example of that is Fuji with their Xtrans sensor. It is very difficult to better their jpges by raw processing.
I would love to go FF, but out of cameras I have tested to date, only the Sony RX1 has got anywhere near the gutsy 18in x 12in B&W prints that the Leica X1 or even the K30 with good glass can achieve.

Being an exhibition secretary, I get to process images from a variety of cameras.

Although full frame images have more detail, to me, they are too smooth they have no depth, guts or edge. Reminds me why so many preferred 35mm over 2 and 1/4 squared in film days. the same goes if resolution gets too high.

Example is the Nikon(spit)D800 full frame at 36meg - horrible results but the Nikon(spit) D4 images at 16meg are really good.

Not trying to show off but I have a K30, Nex3N at 16 meg but, I hate to say this,my Leica X1 at 12meg gives far more gutsy images.
