420-800mm f/8.3 Manual Zoom Lens, Moon/Wildlife | Manual Focus only, 3 T-mount Adapter, f/8.316, Bright Daylight + Sturdy Tripod Required, No AF/IS/Electronics

100% MANUAL NO ELECTRONICS, NO AF, NO IS. Zero electronic contacts means pure mechanical control. You must focus by hand and enable "Release shutter without lens" + shoot in Manual (M) mode. Ideal for learning photography physics; not plug-and-play. ULTRA TELEPHOTO REACH + 3 MOUNTS INCLUDED. 420-800mm zoom brings the Moon, distant birds & landscapes closer. Includes T-mount adapters for Canon EF/EF-S, Nikon F & Sony E. Best for stationary/slow subjects only not for sports or fast action. VARIABLE APERTURE F/8.3F/16 BRIGHT DAYLIGHT ONLY. Designed for compact size and low cost. Requires strong sunlight for usable exposures. Indoors, dusk or overcast = dark/noisy images even at high ISO. Not for low-light or indoor use. TRIPOD IS MANDATORY HANDHELD WILL BLUR. At 800mm, camera shake (even heartbeat) ruins sharpness. Use a solid tripod + remote/timer every time. Focus carefully; many returns cite blur from freehand shooting or rushed focusing. COMPATIBILITY REALITY CHECK BEFORE YOU BUY. Works only after setting M mode + "shutter without lens." Confirmed issues reported on some Sony (a6700, A7 series) and older Nikon bodies. Verify your camera supports T-mount + menu override. No auto-detect, no electronic communication
