So far my 21 SEM and Lux are holding up the best in my Leica stable. And I do use them fairly frequently, but not as much as the 50 Lux ASPH and 28 Cron.
Allen - ~2 months is standard lens service turnaround with NJ. If you convince them of your professional need for the equipment, they will try to expedite it... within a month.
The 28 Cron is now starting to loosen up a touch, and while I tightened all visible screws on it (that could be tightened), it didn\'t seem to fully address the matter. So I\'m guessing eventually it will need service. Good to know you had good results with DAG. I also stopped using the Leica hood for it, because I was always handling the lens by the hood. Instead I\'m using a modded 3rd party vented screw on hood that lets me better grab the body of the lens when changing lenses.
M240, 50 Lux ASPH x3, 28 Cron (self portrait in the spirit of Joakim ) Yes, I\'m shooting with the EVF, which I tend to do now for these kinds of building detail shots. It\'s also great for shooting up without having to crane my neck.
