Honestly Im about to pull my hair out with this kit lens that came with my S5II. I thought the 20-60mm would be enough for my trip to the Swiss Alps in three weeks but it just feels so flimsy and the range is driving me crazy for the stuff I actually want to shoot. I keep missing shots because I'm swapping lenses constantly and I'm just sick of it. I want one lens that can just stay on the camera most of the time because I hate carrying a massive bag around when I'm hiking.

I've looked at the Sigma 24-70 but people say its a dust magnet and that makes me super anxious considering I'll be outdoors a lot. Then there is the Panasonic 24-105 but is it actually sharp enough for professional prints? Ive got about 1300 bucks saved up for this and I really need to make the right choice before I leave or Im gonna regret every photo I take. Is there a goldilocks lens for the L-mount that actually balances weight and image quality or am I just chasing something that doesnt exist? I just want something reliable that wont fail me when I'm halfway up a mountain...
