Hi I just found my father's old ae-1 (not pro) and thought it would be fun to start shooting with it. Bought battery and film but it turned out it needs some mechanical fixing before it works. Parts have been ordered and I think I'll be able to fix it. What I'm curious about is the different types of lenses. I will partly use this for shooting birds and other animals which may be pretty far away. Let's say 15-25 meters away. I've checked eBay and several lenses are to be found. What would your recommendation be? The one I got today has zoom between 80 (75?) - 200. Greetings from Sweden!
