I've been doing some thinking about my lens kit. I've got some top-notch wide-angle zooms, and a 300 2.8 AF that gets the job done. Between these, I've got the 70-200. It's a great lens - tack sharp - and it produces wonderful colors. The thing is...I just don't use it very much. The idea of selling it outright has crossed my mind, but I'm sure there will be times when I need a lens with a focal length between 70 and 300mm. I'm not interested in slower lenses, as I usually shoot in lower light. I'm thinking about going back to an 80-200 2.8. I'm sure I'd miss the VR, but I can always use a tripod or monopod. By doing this, I could put a substantial chunk o' change in my pocket for other fun stuff - or tuition. So, my question is...Have you ever "downgraded" lenses? If so, from which lens to which? Did you miss the original lens, or have seller's remorse?
