When i go out, i find myself switching macro and UWA lens alot -_-
Sometimes, by the time i get my macro lens on, and flash and etc etc, the insect disappear liao. Just an extreme example. I think i was mainly thinking about shooting for event, have a sigma 50 f/1.4 and a 24-70 to swap around. I've never done that though, so it's pure speculation ....
Yeah I think that make sense... so the solution is to get other DSLR... and in the future, buy new body (better one) and I get 2 DSLR.... lolz...
How about getting camera that can accompany you to the rough condition (like really cold place), or maybe camera that waterproof (can I use DSLR when it is raining?), or maybe camera with ultrazoom (because DSLR lens for ultra tele is really expensive).
