Ok guys, so this weekend I had a photoshoot at a softball game. I got some great shots, but the ones I got were with my 50mm 1.8 on the INFIELD. The outfield might as well have been 3 miles from me, since even with cropping, there were only a few decent shots. So I KNOW I need to get a decent zoom lens. I don't care if it's fixed or not, but at this point I just DON'T have the cash for something expensive right now. SO my question is this: Are the cheap zoom lenses WORTH using, assuming sunlight? (at the shoot I was able to set my kit lens at shutter speed of 1/2000 and get decent shots because it was really sunny) If so, here are the lenses I was considering, perhaps someone wouldn't mind telling me which of these would be best? 1. http://www.adorama.com/NK70300AFG.html (OK I admit I like the silver color for some reason.) 2. http://www.adorama.com/NK55200DXR.html 3. http://www.adorama.com/TM75300NKAF.html 4. http://www.adorama.com/TM2880K3NKAF.html (This is a kit, is it worth it?) Anyway, some advice would be really appreciated. I'm hoping to make one of these a present from Santa in a few months. If you have other suggestions, lay them on me.
