I just added a new Quick Poll to find out what lenses we use the most. I think I covered all the bases but if I missed something let me know. This poll will make the most sense for interchangeable lens camera users. But if you want to vote about your point-and-shoot lens, feel free.
What lens do you use the most?
For the past year, I've been using my Canon 18-200mm IS lens the most. It's light, compact, versatile, and the image quality has performed better than my expectations.
