Really interesting thread. I looked backed through my photos and the lens that was used the least turned out to be the 27, but I actually like that lens quite a lot! I have quite a few Fuji lenses (14, 16, 23, 27, 35, 60, 10-24, 18-55, 18-135) but they've all got their purpose. For the type of shooting I enjoy the most it seems the lenses that I am least enthusiastic about - bear in mind they both are excellent - are my two longer zooms, the 55-200 and 100-400. I guess these days I just enjoy wider to normal focal lengths.
