Macro telephoto lens Samyang 100mm F2.8 ED UMC Macro

The Samyang 100mm F2.8 ED UMC MACRO is a macro telephoto manual-focus lens for full-frame and SLR cameras, offering true 1:1 magnification for close-up photography. Its optical design of 15 elements in 12 groups, including High Refractive (HR) and Extra Low Dispersion (ED) elements and Samyang's Ultra Multi Coating (UMC), delivers high resolution, reduced color aberration and controlled flare. With a bright F2.8 maximum aperture, 9-blade circular diaphragm and a minimum focusing distance of 0.307 m, the lens is suitable for detailed shots of flowers, insects and other small subjects, and can also be used as a 100mm telephoto for portraits and distant details.

Advantages

The lens provides true macro 1:1 reproduction combined with a bright F2.8 aperture for precise control of depth of field. Optical elements (HR and ED) and UMC coating reduce chromatic aberration and flare, producing high-resolution images with accurate color. A 9-blade circular aperture yields smooth bokeh and attractive out-of-focus rendering. The metal barrel with detachable petal-shaped hood ensures durability and minimizes stray light. Manual focus control gives fine-tuned focusing for close-up work.

Suitable for

• Macro photography of flowers, insects and small objects
• Close-up product photography
• Portraits where a 100mm focal length is desired
• Detail shots in nature and landscapes

How to use

Attach the lens to the compatible camera mount and secure it according to the camera manufacturer's instructions. Use manual focus to achieve precise focus at short distances; move the camera or subject slightly to refine composition and focus. Start with a wider aperture (F2.8) to isolate the subject and create soft background separation, or stop down toward F8–F16 for increased depth of field when more of the subject must be in focus. Use a tripod and remote release for maximum sharpness at high magnification, and consider focus stacking for extended depth of field in macro scenes.

Recommendations

For sharp macro results, stabilize the camera with a tripod, use controlled lighting or a ring flash to illuminate the subject, and fine-tune focus manually. When shooting live subjects such as insects, approach slowly or use a longer working distance and higher shutter speed to freeze movement.
