Rokinon FE75MFT-S 7.5mm F3.5 Fisheye Lens Micro Four Thirds

The Rokinon FE75MFT-S is a 7.5mm fisheye lens purpose-built for the Micro Four Thirds mount system, delivering a full 180-degree diagonal field of view that captures dramatically wide perspectives. With an optical formula of 9 elements in 7 groups, the lens produces full-frame fisheye images that fill the entire sensor area on cameras from Olympus and Panasonic. The f/3.5 maximum aperture allows for reasonable light gathering, while the aperture range extends to f/22 for situations demanding greater depth of field. At just 1.9 inches in length, it is one of the most compact fisheye options available, maintaining the small form factor that draws many photographers to the Micro Four Thirds system.

This is an entirely manual lens — focus and aperture are controlled via physical rings on the barrel, with no electronic contacts for autofocus, metering assistance, or EXIF data transmission. The remarkably close minimum focusing distance of 3.5 inches allows photographers to place the lens nearly against a subject, creating extreme perspective distortion effects that are a hallmark of fisheye photography. The protruding curved front element is protected by a built-in petal hood but cannot accept standard screw-on filters. This lens is best suited for creative photography, astrophotography, real estate interiors, action sports, and any scenario where the dramatic ultra-wide perspective adds visual impact to the composition.
