I've had the 450D and 70-200 f4L combination and I absolutely loved it for sports! The image quality shot wide open at f4 is very good and sharp. Therefor it's a lot easier to use in certain circumstances. However it all depends on what your needs are. What sports are you refering to? One type of multiple types? Do you think you'd need IS for the other purposes? Are the sports indoors or outdoors? Let us know!

In this case it doesn't really matter. Since the 70-300 would not even take an adapter and retain AF on your camera. So unless you want to try and have an extender and manual focus lens....it's not something you should pay too uch attention to. And yes the 70-200 f4 is capable of an 1.4x extender and retains AF while having one on.


Quote from the review:


"With the 1.4x, the 70-200 f/4 becomes a 98-280mm f/5.6 lens that retains excellent image quality (adding more barrel distortion and some additional CA). But, image quality starts declining more noticeably with the 2x and the resulting 140-400mm f/8 lens only autofocuses on Canon's 1-Series bodies. This combination also results in a very dark viewfinder. The extenders increase the maximum magnification to .31x and .45x. "

The topic titlemakes a small suggestion [A] The new 70-300L is listed at 1500EUROS here.
