That is however not what my comment said - I believe it was completely
unambiguous :-) You guys are just too used to bashing from 35mm
enthusiasts. Since both are miniature formats to me, I happily use them
both when required, and have no personal issues about them. Facts are
facts.

I don't believe there is a rectangular sensor array on the market
anymore that is of such low resolution to render higher quality images
at f/16 than, say, at f/11, unless your lens *really* sucks.

I stand by my statements 100%.

Answering Dawid.
