Which lens

Can i ask for peoples opinion which is the lens to go for between pentax 560 or sigma 500
Thanks Pete

SIGMA 500 pros : faster (f4.5), exceptional IQ and sharpness, robust as a thank, cheaper than Pentax 560, precise and quick AF. cons: no range limiter neither HSM with Pentax version .

Pentax 560mm. At £3000 it's an absolute steal IMHO.

However, I might prefer the Pentax 150-450mm with the 1.4x AW converter. This will cost less, be much more versatile and promises to be a really good combination. At the long end 450 x 1.4 = 630mm. You also get AW construction.

PS The 500mm f/4.5 Sigma in itself does have very nice optical qualities.

Best regards, John

maybe it is also worth to note that SIgma 500 is a FA lens, Pentax 560 is a DA one.
