Canon EF 70-300mm f/4-5.6L is USM Telephoto Zoom Lens Exclusive Pro Kit

Fjor shooting face shots at weddings or other interiors, this is without peer. Fills the frame , works v. well with flash, iso at 1000-1500. Clients love output. Have had/traded several of these, sharpness varies, good to very good, sharpen in post-production. On the other hand, comparable to old canon 135 soft focus if lose focus. Have read other comments, have 70-200 f4 is, v. sharp lens but lacks reach and is conspicuous. Sim, have 100-400 is, great birding lens, but way to heavy and conspicuous for weddings and indoor photos, and it's not that sharp really, is it.

There are two kinds of wildlife photography - setting up with a long lens on a tripod and waiting and those shots where you have to move and shoot quickly before the subject disappears. This lens is absolutely perfect for the second kind where you have to be ready to react and shoot in an instant. The sharpness is very good; color rendition excellent; and the size makes it virtually instantly deployable. Combined with an SLR with the smaller sensor ( a 1.6x effective focal length boost), you can have, in effect, up to a 480mm magnification. Yet, because of the IS, it is very steady and camera motion is quite effectively dampened. Its only two slight drawbacks are that the IS is somewhat noisy and that the lens barrel is slightly loose...even after I sent it back to Canon for adjustment. It does not seem to affect the crispness or clarity of the shots, however. This is one lens I would not be without.
