Well, not trade per say, but I just ordered the Canon 15-85mm lens two weeks ago, making it my third lens (other two are 50mm 1.8 and 18-55 kit lens). The lens was $700 and I love how fast it focuses compared to the kit lens, however, it's a bit heavy for travel photography in my opinion.
I've recently been looking into mirror less camera systems and the Fuji X series cameras/Sony/Olympus systems all look pretty good for travel and just shooting in general. It seems like a pretty good alternative to a DSLR. I'm just wondering if you think it'd be worth it to return my 15-85mm lens and buy maybe a Fuji system? From what I've seen the over $1000 price tag seems to be worth it in the long run as the image quality looks to be on par if not better than the t3i. My only concern is that the mirror less system won't be very good for fast shots and from what I've seen of the Fuji cameras the controls look frustrating to handle.
Anyone have any personal experiences switching to a mirrorless system? What camera/lenses do you recommend? Any regrets?
