I thought this made for some interesting reading although this may be "old hat" for some of you.

I'd like to get some clarification on this part:

Canon cameras have the opposite characteristic. They are incompatible with most vintage Canon lenses, but with cheap adapters can mount dozens of brands of third-party vintage lenses.

Olympus D.S.L.R.’s can mount most of the same vintage lenses Canon cameras can, along with vintage Olympus lenses if you have the adapters.
Does this mean that Olympus can mount dozens of third party lenses except for Canon or can it mount Canon as well? Is there a list of compatible lenses and necessary adapters somewhere? This seems like a great way to build up an arsenal of lenses on the cheap. It also would suggest that Olympus would be the best choice for using vintage lenses as it offers the most compatibility.

I would agree with the quote in the article that says it's easier to manually focus the older lenses than to switch the new digital lenses to manual focus. I'm used to some kind of split prism or other visual cue other than a flat palate you get with the digital lenses for Olympus. I guess it takes practice but I find it difficult to fine tune the focus that way.
