I'm looking for a small (size, not focal length) lens that will cover 8x10 and a llow for reasonable movements. My preference is for something in the 210-240mm range. I found a reference to a "mystery lens at: http://www.photomall.com/gele ns.htm. Check this list for a 210mm f/8 lens that is not identified, but is all eged to cover 11x14! Any idea as to what this lens is? Are there any good alte rnatives?
