Thanks Lowell, which lens IYO is better optically 300/2.8 Sigma or Pentax FA ?
I cant honestly say as I have neither, I am still stuck in 77mm land (front element diameter that is
) I think, however that given the much newer design of the sigma lens, it might have an edge, and it is available new as opposed to used. What ever you do, go for a pair of sigma TCs as well.
At the present time, my sigma 70-200 F2.8 plus their 2xTC work very well on my K10D, as does my SMC 300F4 and 1.7x af TC (used with a flash on my *istD)
A bigger diameter lens, either 112mm for 300F2.8 or 500 F4.5 or something larger, is the next step, but given the quality of the optics I have now, I think i might be better off with the next pentax DSLR which will hopefully have K10D ISO200 quality at ISO 1600 or ISO3200. For me, better high ISO is
MUCH more important than more megapixles
