So far, I think this is the lens I am most interested in so far, unless Canon surprise announces a 100-400 replacement . Although, the 24mm Pancake is a bit interesting, I'll take one on an SL1 for street photography

I've been wanting a fisheye for a while, and was considering buying Canon's 15mm f/2.8 used, (don't want to drop $1,000 on their L fishy) so this coming along now is great, assuming it's going to be around $500~

What does everyone else think of it? I plan on using it, if I get it, for shows, landscapes, starscapes, and maybe some extreme sports like BMX, skateboarding, snowboarding, etc.
