I have been using the canon 75-300 usm ( non is) lens and would like a lens which gives me better quality images and full zoom. I was looking at the 70-200 F4 (possibly with 1.4x extender). However I read a few reports that is suffered from some issues on the 300D. Just wondered if anyone had any problems with this setup

I borrowed one for a weekend during the summer and I had some backfocus problems with that lens. The strange thing is, the person that I borrowed it from also uses it with a 300D and he has no problems with it at all. A shot I took with some backfocus is at http://webpages.charter.net/stevekempf/70200f4backfocus.jpg . The F16 fills the frame and the red AF lights were lit on the the airplane. The cockpit is blurry but the trees behind it are much sharper. I don't want to scare you off from the lens because I know I am the minority but I did get several shots with this problem over the course of that weekend.. Good luck with it.

I too used to use it with a 300D and now a 10D and never had a problem - one of the best lenses I've ever used. I use the 1.4x extender on most of my aviation photography telephoto shots and again, never a problem or noticeable loss of quality.

I have it and have had no issues with it at all. I love it. I don't get to shoot too many aircraft, but have liked the results where I have. If you are close to the airport, it should work well. I don't think it would be good for real long-distance shots, but for moderate to close, it should work well. It is also a great lens for many other uses.

Well I decided to go ahead and get the 70-200 F4 it arrived today and if nothing else the quality of the lens is fantastic. The focus speed is much faster and you can only just hear it. I will be getting out this weekend and hope to add some shots to the database soon
