after much soul searching, I think I am going with the newest K5. The major disappointment with Pentax for me has always been the auto focus, but that, for the most part seems to be better. besides it will be a good base for better future lenses.
now the question. I have a sigma 17-70 2.8-4.5. we have the fa50 1.4 and the M135 3.5 as well as other manual lenses.
would a Tamron 90MM 2.8 macro be a good fill in gap between the 17-70 and the 135?
I want a sharp lens that doesn't break the bank until I can afford a better lens to fill the gap.
for a general all around affordable lens for portraits, occational weddings, kids, pets, sports,etc. would it be a wise choice?
generally I pre-focus any lens I am shooting in order to shorten the time it needs to autofocus.
I really want the sharpest lens as possible that isn't in the thousands
thanks
