I've got an EOS 300 (film version, not digital) and I was thinking about getting a new lens for it. All I've got is the one which came with it. It feels plastic and I'm sure I can getter better lenses. Anyway, I was browsing the web to see what kind of a lens mount is uses, and it's got whats called EF. I went on to Jessops site to look at what they've got , but there's nothing called EF. There's something called EF-S but they are all really expensive. Can this camera use the Canon AF lenses? Also any suggestions for cheap lenses, i.e. £150 and under?
