Does M43 zuikos have diaphragm problems?
7 months ago

Hi,

I'm a long time user of 43rds equipment: E3+E5 with two lenses, 12-60 and 50-200.

Along the years I have had 3 problems with the diaphragm of my two lenses: first, the 12-60 got stuck completely closed in the middle of a vacation (hence the lens became unusable). Send it for repair (4 months here in Brazil!!). Then my 50-200 got stuck completely open (I use it that way for a year now). Now this weekend my repaired 12-60 got stuck completely open...

I've taken around 15000 shots with the 12-60, and almost 90000 with the 50-200. For comparison, my ooooold pany P&S FZ50 still works perfectly, despite being used around 30000 shots along many more years. As you may guess, I don't share the high praise for zuiko lenses.

So I decided to change system, and I like m43rds. Thinking about the em1 + 12-40 + 60 macro + 20 + 100-300. However, I am *deeply* worried about the two oly lenses, of course.

I would like to know if this has been a known problem for oly m43rd lenses? In that case, I'd go with pany.

Thanks,

L.
