Optical Performance and Image Quality
The Samyang AF 75mm F/1.8 delivers exceptional sharpness across the frame with beautiful bokeh thanks to its fast f/1.8 aperture. Its 9-blade diaphragm creates smooth out-of-focus areas perfect for subject isolation. The OM System M.Zuiko 60mm f/2.8 Macro offers outstanding edge-to-edge sharpness optimized for macro work, with excellent color rendition and minimal distortion even at 1:1 magnification ratios.
Autofocus Speed and Accuracy
The Samyang features a fast and quiet STM motor that provides reliable autofocus performance for portraits and general photography, though it can occasionally hunt in low light. The OM System 60mm excels with its precise MSC (Movie & Still Compatible) autofocus system, offering exceptional accuracy for critical macro focusing with smooth, silent operation that's ideal for both stills and video work.
Build Quality and Practical Use
Both lenses feature solid construction with weather sealing. The Samyang is compact and lightweight, making it an excellent walk-around portrait lens with comfortable handling. The OM System 60mm is slightly heavier but offers superior durability with professional-grade sealing against dust and moisture, plus a focus limiter switch that speeds up autofocus by restricting focus range when not shooting macro.
