So the first "good" lens I bought for my 60d was an efs 15-85. I bought it for all around, day to day pictures. However, what I'm finding is that I don't use my lens because I don't feel like dragging my big dslr everywhere.
So what I'm thinking of doing is selling my 15-85 and getting a used X100. I'd only be paying about $50-$100 more. My thought process is that I would much rather bring along a camera that size, that I can just throw in my bookbag.
