Originally posted by Buckeyemikie I would appreciate comments on the number/percent of keepers those of you shooting with the DFA 150-450 on a KP achieve on average.
A bump for your question, which seems to have slipped by unnoticed (in a flurry of awesome images). I assume that you are asking about moving subjects (e.g. birds in flight) rather than stationary ones.
I don't have the 150-450, but I'd be happy with 20% keepers for BIF with the FA*300 f4.5, Sigma 400mm f5.6 or even the DA 55-300 PLM (very fast AF), whether mounted on the K-3 or KP. Of course it depends on the subject - a slow-moving pelican is one thing, but a swift is something else.
