The Canon 50mm lens is a great buy. It's around $80 and gives you a fast prime lens at a reasonable price. I used mine for a number of pictures and enjoyed it. At some point, I guess when it was sitting in my car during a hot summer day, the lens assembly which I think is held to the case by glue became well unglued.
When I sent it to Canon they told me it is "Beyond Economical Repair" and they would return it unrepaired. As it was $80 I understood this. As I had only owned it for a couple months, I was less impressed by their warranty (or lack thereof). I suppose you could argue I put in it "harsh" conditions but really, my car reached maybe 90-100 degrees? I guess there is a reason it's only $80.
Since then, I've managed with it, getting some great shots even in it's broken state.
But those times are over. After the last wedding, the 50mm had enough. The autofocus cable that was keeping the lens to the case snapped and that's pretty much all she wrote.
