Fixed focus lens Samyang 100mm F2.8 ED UMC MACRO

Samyang 100mm F2.8 ED UMC MACRO is a macro telephoto manual-focus lens for full-frame and MILC cameras, offering 1:1 magnification for close-up work. With a 100mm focal length and bright F2.8 aperture, the lens is suitable for detailed macro subjects such as flowers and insects and can also be used as a short telephoto for portraits and landscape details. The optical design uses 15 elements in 12 groups, including HR and ED elements, and features Ultra Multi Coating (UMC) to reduce flare and ghosting. The minimum focus distance is 0.307 m, the filter size is 67 mm, and the lens is available in multiple mounts including Sony E.

Advantages

The lens provides 1:1 true macro reproduction and a bright F2.8 aperture that allows faster shutter speeds and controlled background separation. HR and ED glass elements together with a 15/12 optical construction deliver high resolution and minimized chromatic aberration, while Samyang’s UMC reduces flare and ghost for improved contrast across the frame. A smooth manual-focus ring and a nine-blade aperture that rounds at smaller stops give pleasing out-of-focus rendering. The metal housing and detachable petal-shaped hood ensure durability and reduced stray light.

Suitable for

• Macro photography of flowers, insects and small objects
• Portraits with compressed perspective and blurred background
• Close-up product and detail shots for e-commerce and catalogues
• Telephoto detail work in landscapes and nature

How to use

Mount the lens on a compatible camera body and set the camera to manual or aperture-priority mode for full control of exposure. Use manual focus and the smooth focus ring to achieve precise focus at close distances; for 1:1 macro shots position the camera so the subject is at or beyond the minimum focusing distance of 0.307 m. Select a smaller aperture (higher f-number) such as f/8–f/16 when greater depth of field is needed, and increase shutter speed or use additional lighting to compensate. Attach the included petal-shaped hood when shooting in bright or backlit conditions to reduce flare.

Recommendations

For best macro results, use a tripod or focus rail to keep the camera steady at close distances, consider focus stacking for greater depth of field, and work with diffused lighting to preserve color and detail while avoiding harsh shadows and reflections.
