Hi guys, I've got some spare cash and will get one of these three options. Please help to point me in the right direction...
I want to use it/them for mostly nature and architecture type subjects, as well as airplanes (on the ground) and cars.
1.) Canon EF-S 15-85mm + Sell 18-55 IS- I'm not sure if 15mm is wide enough for what I want to shoot. 18mm was nowhere near wide enough for many airplane shots, and isn't wide enough for good landscapes.
2.) Sigma 8-16mm + Keep 18-55mm IS- I'm liking the idea of this combo, but the 8-16mm isn't really a good walkaround solution. I'm not too fond of the kit lens either.
3.) Tokina 12-24mm f/4 II + Nifty Fifty + Sell 18-55 IS- This is the most complicated of the options but it would give me a more viable walkaround/wide angle lens as well as a cheap prime to cover the 50mm range, which I don't use much anyways.
Thanks for any suggestions/votes you guys have!
