I've been thinking about purchasing one of the Olympus OM wide angle primes for use on my 5D. I know the adapters has been discussed before, and I have read several threads, but I was hoping for some recommendations: 1. The adapter prices on ebay vary enormously, from $20 to $100 plus. I know you frequently get what you pay for. Can anyone recommend a good quality medium priced adapter? 2. I see now that some adapters provide AF confirmation by means of a pc board and contacts on the adapter. These look kind of fragile in the photographs. I know the OM-EOS adapter has to be very slim (2mm?), so there isn't much to work with there. Again, does anyone have positive experiences with a particular brand? And has the AF confirmation been worth the extra expense? Thanks for any advise.
