Summary: This is my second 1D Mark III. The first one I received from Amazon, although beyond the registration number from Canon that had problems, it didn't perform well. Out of 1236 test wildlife photos, only about 30 were in focus.
Summary: I purchased the Canon 1D Mark III about 1 year ago from Amazon for $4300.00. I liked the feel of the camera and the battery worked great, but the images it took were nowhere near the quality they should have been.
Summary: I had semi-switched from Nikon to Canon with the purchase of this camera. Despite reports over focusing issues, I haven't had any real problems with it. The frame rate and high ISO on it is phenomenal.
Summary: I want to give this camera 5 stars I really do but I use and love it to much to be anything but honest. I have used this camera for everything and have never felt like I needed something else. Coming from a 7d, 60d, and a sl1. This camera excels even past these semi-modern day cameras.
Summary: After reading bad reviews on the focus problems with this camera I waited a while to pull the trigger. I shoot sports, equestrian (some indoors), and stage dance. I bought this camera for low light useage, and the superior focus speed. I have not been dissapointed.
Summary: This is a hand-on impression and not a detailed review. I used the EOS 1D and the EOS 1d Mark IIN before. In addition, I also own a EOS 30D and a EOS 50D. The first good surprise is that this camera is NOT as heavy as you would expect from this bulky size.
Summary: Overall this camera is amazing. The only problem is the focus problems that are well documented elsewhere. The mirror fix and firmware upgrade from Canon helped, but there is still a tendency for focus to drift when shooting rapid fire.
Summary: SYNOPSIS I have had this camera for two months and LOVE it! The build quality, colour "truth", speed between frames, and ability to set custom features is remarkable. I am disappointed with the AI Servo reliability but relieved to see that there is a hardware fix.
