As I recall from reading various threads, the III had all sorts of problems and there were focusing issues, mirror issues and so on, which frustrated professional photographers no end. Not much fun for serious enthusiasts either.
When the IV comes out, will you wait and see if there are issues or buy it as quickly as possible? I'd be tempted to buy it quick but I don't earn my living with a camera so repair issues won't be so critical, just annoying.
Opinions?
Thanks.
