My cousin is very interested in getting into photography, in particular sports photography. He's been taking a lot of pictures lately with his P&S camera and is interested in moving up in the photographic world. So far he's leaning towards the Canon Digital Rebel XT. It seems to limit the user less than the Nikon D40 (because you are able to use AF on all lenses). However, it seems the harder decision is the lens. Third party lenses are not ruled out due to price restrictions. He'd like to spend around $400 for the lens. Since he wants to do some sports photography, the vast majority of which will be in the daylight. I thought that a lens with a reach of around 135mm minimum would be good. This would give him an effective reach of 216mm, which, I imagine, would be fine to start with for sideline shooting. However, I imagine that one would need a decently fast lens and the only ones that I see, from any company, are ones with an aperture range of 3.5-5.6 or so. Would such a slow lens allow for fast enough shutter speeds to stop the action in daylight? Sorry for the lengthy post, but if anyone has any suggestions, they would be greatly appreciated.
