Hey all, since I started using my first FM2, I've been using a 35-105 zoom as a single lens to carry for backpacking. I have been pretty happy with it, but would enjoy something a little wider. Some folks don't feel this is the best quality and that there are newer zooms that are better. I'm looking for some recommendations, taking into account sharpness, contrast, distortion, speed, weight, size, etc.
What would be your choice for an all-around, carry it for multiple day hikes, lens?
Thanks.
