I've got my first "pro" lens in this range, but at first blush I'm not very impressed with it. I'm not sure if there is something wrong with it (it makes a noise when I rotate it, which I don't think is Good). Before I send it in for service, I'd like to try the front/back focus adjustment. However, I'm not sure I understand the whole process yet and whether the K-5 can "remember" this lens. Does anyone know if this lens has a "Lens ID" that communicates with the body so the setting can be remembered?
If doing the adjustment doesn't solve the problems, I'm going to have to see what it will cost to get this thing serviced. I've read good reports about this lens, and although it is heavy that's a property of its construction and the big glass it contains to get you the constant f2.8. -- 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.
