EOS Bodies - For Stills / Re: How good is the 7D autofocus system?
« on: August 12, 2012, 10:13:49 AM »
I just read sproggit's entry. My experience with the Canon 40d and the Canon 100-400mm was completely different. Sproggit mentioned that the said lens was not a USM, I just checked mine out and is says Ultrasonic and the literature says it is a USM. Maybe not. Nothing but soft images with this combination, began to think it was the lens. But once in a great while I would get a very sharp image and wondered why that was such if in fact I got a soft copy of the 100-400.
Last December I left my home in New England for a couple of weeks in California. I just purchased a Canon 60d and took that with me. My wife and I like bird watching. We noticed that a local state park was doing a bird watch. On the watch we spotted a California Scrub Jay. Took out the 60d and the 100-400mm and took two pictures expecting the worst. To my shock both pictures were perfect. Took a lot of pictures of Canyon Towhees, Acorn Woodpeckers and such. When I went inside to get out of the California Sun I was surprised at how good the captures were. It was then I decided that the Canon 40d and said lens has some front or back focus issue. I am more certain of that now having read sproggit's entry and his experience with the 40d.
I decided to acquire a Canon 7d. It focused just as well as the Canon 60d except in AI Servo in which to me was a little faster then the 60d going near to far. Pictures are just as sharp but the 7d seems to have a slight banding issue. To me there wasn't a lot of difference between the two. The points do cover more area and I kinda of gotten some decent picture of birds in flight. Personally for me it's more about good mono pod and technique but I am no master of that. NOW should I get my 40d fixed?
