Hi. I already have a tokina 10-17 but want to get to get a topside wide angle lens (for my D7000). It seems a shame not to get one that will also be useful for underwater use one day.
The nikon 10-24 looks ideal but it a bit out of my price range at the moment so I was thinking maybe a tokina 11-16 or the sigma 10-20 which would have a mode useful zoom range.
Any comments on these two lenses and/or any other recommendations? I'd like to photograph whales at some stage so I'm really after a lens that could handle that sort of thing too....
