I have a Chronos 1.4 and am using a zoom lens that I bought (either the 2.8-12mm f/1.4 zoom lens or the 6-60mm f/1.6 zoom lens). Unfortunately at the largest resolutions I get vignetting. Note I don't have the Chronos 2.1 HD, which has a larger image sensor chip. I just have the Chronos 1.4. However I'm still getting vignetting with this lens. So I want to get a fixed-magnification lens (no zoom). And I have several choices (Computar 12mm f/1.4 prime lens, Computar 8mm f/1.4 prime lens, and Fujian 35mm f/1.7 prime lens). Which one or ones of these will avoid vignetting on a Chronos 1.4 on even the highest resolution setting? And of these, what field of view should I expect to get on the highest resolution setting, for each of the non-vignetting lenses?
