I find myself lately wanting to use lenses with manual focus and manual aperture on my EOS cameras. This is mainly to simplify full manual operation on cameras where the shutter speed and aperture use the same control. I understand that the FD-EF adapter is only useful with some of the telephoto lenses. I want something that allows use with both wide angle and telephoto lenses, possibly with zoom, though that is not important. Ideally, I'd like to be able to use this system on both my older 35mm cameras and my current model D... camera. I'm most interested in starting off with just a few lenses. I'd like something wide, around 18-28mm, a fast 50mm, and something around 85mm. I may want to add more later, like something around 200-300mm, but I can usually walk, so long lenses aren't terribly important. I have two problems with this project. First of all, I'm on a tight budget. The cheaper this can be done, the better. The second problem is that I don't know where to start. I'm unfamiliar with non-Canon lens systems. What would be the best system to look at?
