<p>[QUOTE="rmpsrpms, post: 1542641, member: 31773"]Well, a microscope has additional optics not present in the MPE-65. There's really nothing special about the MPE-65, it's just a 65mm lens with a long throw. I suspect it shortens focal length, because if it didn't it would have to extend almost 300mm to get to 5x. This further reduces working distance, unfortunately. Microscopes generally have objectives that are optimized for a given magnification, while the MPE-65 is rated over a wide range of mags. So using the MPE-65 is still in the realm of PhotoMacrography, not PhotoMicrography.[/QUOTE]</p><p><br /></p>
