Most primes do not rotate, pk and pka lenses mostly don't , most af zooms do
Good in terms of the front element not rotating for focus:
Pentax F 1.7 50mm doesnt
bad front element rotates:
PentaxF 70-210 does
Sigma 70-300 does
I'm not looking for IQ that can be searched for i just want to find which lenses do not rotate the front element and preferably auto focus
I have or had the following:
zooms: F 35-70, DA 18-55, DA 17-70, DA 16-85, DA 55-300 SMC, DA 55-300 PLM, of these only the F 35-70 has a rotating front element.
primes: F 28, FA 50, all DA Limiteds, DFA 100 Macro WR, DA* 200 and 300, none of these have a rotating front element.
I think it is safe to say that none of the current FA, DA and DFA lenses currently in production have rotating front elements. Many of the current DA zooms are also internal focus so the inner element doesn't move in and out as well doesn't rotate while focusing but will extend when zooming out.
