Do you still have any Leica R lenses? You can mount them on a Pentax with an adapter. If you don't want them anymore, I'd be interested.
Originally posted by zapp Now I am building a Pentax system, starting with the K5 and the 31 mm lens. Next will probably be the 55 SDM and some other lenses.
IMHO, the 31mm is an excellent choice but the 55mm does not live up to the quality of the FA Ltds.
Some might want to shoot me for saying this, but if you don't mind MF, I suggest you should get a K55/1.8 rather than a DA* 55/1.4. That would be my choice (regardless of price).
After the 31mm, I'd suggest the FA 77/1.8 Ltd and the FA 43/1.9 Ltd. These are lenses that have the quality and character that should satisfy someone coming from a Leica.
The newer, DA Ltds are competent but not quite as magical as the older FA Ltds.
Are you considering zooms at all? The Pentax DA* 50-135mm is very good optically. Unfortunately, it has a bad history of SDM failures. Some users seem to luck out though and don't have issues.
