General photography but some moving sports, I have been shooting a lot of soccer lately. Because of that autofocus speed is pretty important. I am talking on an amateur level though not pro.
I have had decent results with the 100-300. From reading these boards and others I am getting the impression that a zoom lens with a fixed aperture like a 75-200 2.8 is a lot better for that kind of work. A LOT more expensive though.
I guess I would like to keep my pentax lens's but I don't want to kick myself down the road. I feel kind of burned by the 8800 the shutter lag is maddening and I don't want to make that mistake twice.
My budgt for the body is roughly 6-800.
I also have Photoshop CS2 so I can handle raw images
