Hey Mark, Try the Canon 15mm USM fisheye at Adorama or B & H. To see a sample using this lens, try this link at Fred Miranda forums, there is a sample pic with a MK II of seal on a beach in the 8th post, plus some other samples further down...

Mike, Looks like Cannon does not make a specific fisheye lens for the 350/400/20/30/40D line. They do make a wide angle, 10mm-22mm lens. Thats the widest I've found, but it's not a true fisheye. so you will get wide angle, but not the fisjeye effect you are looking for. Link to the lens is Here Sigma makes an circular 8mm...

Yeah Squid, you're right that only a full framed body will show the entire results from a fisheye lens. Since the sensors in Nikon and Canon 1.6 bodies are smaller than the full frame, the light that is bent around the edges to pull the extra field of view in falls outside the sensor. You may get some, but not...

I just posted one of mine from a few years back... here 'tis... a photo of Seth Edwards and Hemond's MX park in Minot, Maine shot close-up. I was standing on the 60' table about 12' from the lip with a 24-70 2.8 at 24mm. I was just practicing my timing trying to get the riders just after they left...

Canon f2.8L 70-200... versatile, fast, and add a 1.4 tc and you have nearly the 300 (280) with f4.

Another tip... when the lightening to horrible (overcast skies or rapidly changing from sunny to cloudy) try to take shots with a dark background. Get higher than the rider or on the same level so you have trees/people/hillsides in the background. This will help keep the camera from being "fooled" when calculating the exposure. You might end up talking more...

Nice framing on the jump sequence. Good timing to get the look-back. Nice job with the new camera! Overall, they look underexposed. First try shooting with the sun to you back or near to your back as much as possible. Remember, the sun moves so if you are shooting for any length of time, move as the sun moves. You...
