The DA*'s offer both options (SDM and screwdriver), the sole DA SDM lens (the 17-70) only does SDM.
I'd look very carefully at the K200D as an upgrade from the DS, it's a downgrade in many ways (smaller buffer, worse viewfinder, only P-TTL flash) but does give weather-sealing, a grip, more pixels and SR. A used K10D would give more camera for much less money as it lacks the limitations of the K200D other than flash protocols (P-TTL only as well, but it can wirelessly command). -Adam On Mon, Jun 9, 2008 at 3:37 PM, gldnbearz <[EMAIL PROTECTED]> wrote: > Can someone educate me on the SDM enabled lenses?
