So I accidentally won an eBay auction for a 5D, and it arrived this evening. I figured what better way to test it than to do a quick photo shoot with Julie! 1. 2. 3. 4. 5. My only disappointment is that due to space constraints I had to shoot with the cheap 50mm 1.8 instead of one of my better lenses, but I'm still quite pleased. The detail over the 50D is just astounding. I gave it a try outdoors at ISO3200 with both the 100L and 70-200L and got some decent results for being quick test snapshots. At 3200 it has only a little less noise than my 50D straight out of the camera, however, it cleans up with virtually no trace of noise very, very easily. The 50D cleans up to a usable state, but requires much more work and the banding at the top of my frames still causes me issue. I'm going to test it a bit more tomorrow with some action shots (shooting another dog event) to figure out how it's going to track with Ai Servo, but I think for the indoor dog show I have on the 28th-31st it's looking to be very promising thus far! I think the hardest part is trying to figure out which lens/camera combo I'd want to use. Since focal length won't be an issue I'm thinking the 17-50 on the 50D and the 70-200 on the 5D makes the most sense at this time.
