You'll want to have either a preset lens, or one with fully manual diaphragm your dSLR cannot trigger aperture pin on an M42 lens, sometimes the pin can be glued though. I have three different adapters, and Pentax original one is clearly the best one as it allows focusing to infinity and the lens fixes with correct right side up. With third party adapters, make sure it is of the thin makes-even-surface-with-bayonet design - the ones that have a metal layer over bayonet will not let your M42 lens focus to infinity. Adapters are not too expensive, available from both Pentax and third parties. There's a huge selection of those lenses available. Those lenses are quite heavy and you'll need an expensive adapter for them.īefore K-mount, Pentax used a screw-mount called M42 you'll need an adapter to use an M42 lens. In addition to the K-mount still used on most current Pentax DSLRs (except medium format, like 645D or 645Z), there were Pentax 645 and Pentax 67, both are medium formats. They will have focus confirmation, IS, center/spot metering, and can actually use Av mode as they will stop down with the aperture ring.

You can also get a M42-PK adapter and use the endless supply of great cheap screwmount lenses available at ebay, pawnshops, etc. They have an extra pin which will get stuck if it is not removed. There is a rare breed of K-mount that Ricoh used, called "KR" mount.

These two series do not get matrix metering, just center-weighted and spot, but do get focus-trap. Metering on these digital SLRs tends to be noticeably more inconsistent than on on the film SLRs they were designed for. It can also suggest a shutter speed if you push the +/- or green button (depending on camera model and settings). Instead, you'll have to use M mode, but you will get meter readings.

The oldest two series, K and M series ( database), do not have aperture contacts, and thus do not work with Av and Tv mode. This includes autofocusing (if applicable), focus confirmation, metering, IS, etc. Yes, all Pentax DSLRs accept all K-mount lenses.
