Been a long time Canon user, sold off all of my FD and EOS film equipment a long time ago, now all digital. Recently acquired a Canon AE-1 with a 50mm f/1.8 lens for nostalgia sakes. Just won an A-1 on eBay, it comes with a 50mm f/1.4 lens. Can someone please supply me with the correct lens hood numbers for these 50mm lenses? And where I might find them? I see some on eBay but don't know what I need. Thank you!
