Omegon M48 Extension -<\/strong> More play space, perfect image<\/strong>
Omegon M48 20mm Extension Piece gives you exactly those extra millimeters you need to set your camera or corrector at the right distance. No more forced back focus. You achieve sharpness all the way to the corners, without vignetting or tilt.<\/p>\n\n\n\n

Simple and firm coupling<\/strong>
Both sides have a wide M48x0.75 thread. Screw your flattener, reducer or camera directly onto it. Everything sits tight and stays perfectly centered.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

Compact and light<\/strong>
Only 51 mm in diameter and all aluminum. Adds almost no weight and fits nicely into your existing train.<\/p>\n\n\n\n
