Well, I am trying to get started in wildlife photography. So I walked into the local Photo store with my Canon Rebel XTi/400D in one hand and the latest issue of DU in the other. I said "Well I have this, (my camera) and I want to do this (The DU cover pic.). What do I need and how much money do I need to save?" He tells me, "All you are going to need is this." Then sold me a 70-300mm tameron. "This is all you're going to need, you can get published photo quality with this. You can always upgrade later but I doubt you will ever need anything more than this." Sounds great. I can't wait to get it home. I slap it on and head to the park where I know the local park ducks will be. I see a bunch about 20 yards away and zoom in with my new lens. Very disappointed. So i find a few more birds all within about 10-15 yards of me and quickly realize this isn't what I had in mind. The only way this lens seems to be able to bring the subject into your face is if you get close enough to be...well...in your face. I am VERY new to this so I'm wondering if I am missing something, or did the photo guy miss something. I read all the paperwork that came with the lens, which isn't much, and it appears I am getting all I can out of it. I think I need a more powerful lens to get the kind of picture depicted on the DU cover. I just wish the store guy would have told me that. Maybe he knows something about the lens that I have yet to figure out?
