60-250 is dual AF, as are 16-50 and 50-135, 200 and 300 AFAIK Which means it sports screwdriven AF as well but since the lens communicates with the body, only SDM will work (even if dead).
To circulvent that, one should short the digital info pin presented on the from Kmp: http://kmp.bdimitrov.de/technology/K-mount/Kaf.html This pin came with KAF mount but is still there. Shorting it will get you screwdrive AF, but will prevent any digital info which means focal length, MTF, lens ID etc. Annoying, but you can get AF back if needed. Better than nothing. 60-250 really does miss an aperture ring. 2010/12/19 Boris Liberman <bori...@gmail.com>: > On 12/19/2010 12:45 PM, Thibouille wrote: >> >> If you tape the digital pin, the 60-250 will focus noisily enough :) >> And this is an FF zoom. > > Can you please elaborate about this digital pin??? > > Boris > > -- > PDML Pentax-Discuss Mail List > PDML@pdml.net > http://pdml.net/mailman/listinfo/pdml_pdml.net > to UNSUBSCRIBE from the PDML, please visit the link directly above and > follow the directions. > -- Thibault Massart aka Thibouille/Thibs ---------------------- Photo: K-7, Sigma 28/1.8 macro, FA50/1.4, DA40Ltd, K30/2.8, DA16-45, DA50-135, DA50-200, 360FGZ ...
