I have an Ex1 with very little hrs. Just had the entire lens assembly replaced at out cost by sony. We shoot on RED epics, so it has sat for some time and is in excellent condition with original box/manuals etc.. Llet me dig up the invoice from sony and do a little math. I'll get back to you late monday?
Feel free to send details via PM as I believe prices/negotiations are done that way here as opposed to posting direct. I'll PM you now so you can just respond that way.
