I have to admit to being totally ignorant of optical theory, so it's possible that this is a really dumb question. But here it is. I recently bought a cheap Canon FD adapter for 4/3 from a Chinese company on ebay. The ad clearly stated that it would not allow the lens to focus at infinity, so I didn't have great expectations. What happens when I mount my 50mm FD lens on the G1 is that I end up with a really good 50mm macro lens that won't focus beyond a foot or so. I'm not complaining because the lens only cost about $30, and it really does make a wonderful close-up lens. But I was wondering why this happens, and why an adapter from RayQual, for example, doesn't have this problem. I'm thinking about getting the RayQual adapter too, but I am curious as to the mechanics behind all this voodoo and witchcraft. Can anyone explain it in such a way that even I can understand?
