Y'know what else would be interesting? For those of us that use a dbase program like Lightroom, Bridge, Elements or Aperture to see real statistics of what lenses and/or focal lengths they use most often it might surprise a few of us from what we think....
But MA I'm pretty much with you- all over the place, depending on what I'm shooting.
I have this one little lens that is special to me though- it's a Pentax DA 35mm 2.8 macro Ltd. That little bugger is tack sharp, compact yet made of steel, can close focus, and I like that focal length which on a crop sensor body is roughly 50mm in terms of 35mm film/full frame equivalent.
But it's not the one I use the most because I prefer zooms and have a mild aversion to in the field lens changes.....
