LOMO's exclusive MVP™ (Microscope Video Pointer) allows you to point at anything on your monitor screen without an expensive electronic device. Controlled by a knurled Joystick, the needle pointer is omnidirectional, easily focusable and, if necessary, completely retractable for unobstructed observation. The MVP accepts any CCD camera with C- or CS-mount and fits any standard (Ø23mm) compound (monocular, binocular or trinocular) microscope. Used with the A-ETI eyepiece tube adapter, it also fits any stereo (Ø30mm) microscope. The MVP incorporates a focusable 16mm, f/1.6 lens with a convenient rubber grip.
