I just wanted to get out and take some shots and play with settings since I need to be on the top of my game tomorrow and all I got was rubbish- one or two okay-ish shots apart from anything else I had a stinking cold so I didn't feel too good. The good news is it seems to have passed off....but which zoom for tomorrow? I know my 18-55 but is that going to be long enough? My other options are a 18-200 Tamron I picked up the other week secondhand and have only put on the camera to check it worked and the 300m Sigma that I only just found out works with the D7000. I'm okay on the primes, Tamron 90 macro and the Nifty Fifty but is this a good set up for wildlife?
