I'm looking for a new "general" lens. Right now, my combination is the 12-24mm and the 28-70mm, both of which are enormous and heavy. I use a Nikon D300 body. I'm basically looking for suggestions on where to go next. I've looked at the 17-55mm, hoping it could replace both (I don't shoot ultrawide that often, 17 might cut it) but that's also a very big lens. I looked at the 16-85 VR, which has a perfect range, but I don't like the variable (and slow) aperture. The 35-70 would be nice, but they're hard to find in good condition now and demand an unreasonable price premium as far as I'm concerned. I'm not in love with push/pull either. Anything I'm missing? I'm very open to 3rd party lenses (I've had good experiences with Tamron, Sigma and Tokina) and I'm not against using primes and switching up a lot. I don't want to spend any new money, just what I would get from selling one/both the 12-24 and 28-70 (probably $1600 or so). Wants: Lighter than "The Beast" 28-70mm. Good range (doesn't have to go wide if I'm keeping the 12-24). Very sharp - the whole idea here is getting nice images and I'm just a hobbiest, so I want the very best for my money. Thanks for your help!
