So I'm looking for suggestions with pros and cons for a fisheye for me 40D. Not a converter, a real lens. My buddy on here (FRODO.) has the Tokina 10-17, I've been thinking that's a good choice. Any other suggestions?
Another nice thing about the Tokina 10-17 is that it can fit with any crop sensor (1.6 and 1.3) and even full frame. My vote stands for that lens. If you're simply looking for a wide angle though, go with the Canon 17-40 f/4L. Incredible quality, literally zero distortion and almost no vignetting. Very high quality.
With the 1.6x crop factor there aren't a lot of options. The Tokina fisheye is the best bang for your buck fisheye for this camera. There is a Sigma 10mm f2.8 that I've heard is pretty good also but pricey.
Nikon 10.5mm. Yes you heard me right. It's an awesome lens and canon users use nikon lenses regularly. I have one for sale if you're interested. Check my threads.
I have the 10mm on my 40D and I love it. I have been using it for skating, snowboarding, skiing, and even portraits. Its really good quality lens. only downside is its for 1.6 crop only I believe
I don't. I shoot nikon but I'm sure they're out there somewhere. When I was doing my research on the lens I remember reading about a lot of canon users buying them because it was the perfect price point for them. Try flickr.
