This one for me is more of a hypothetical question, or question for far in the future as I am currently saving for a FA31.
But which lens is your favourite? Both are really quite different and both have high image quality.
The DA* has the advantage of weather sealing (would provide great piece of mind with my sealed k-5), Zoom, SDM (Im not worried about the failures). It does look like a whopper of a lens, but maybe it will make me look pro.
The FA is faster, smaller, metal...er, prime-er. Probably a bit nicer for portraits, but maybe the extra zoom of the DA would bokeh similarly to the FA?
As for my own personal photography style it is a mixture of landscapes, friends and travel (nepal this year, woot!)
Opinions? Personal experience?
