Sony FE 100mm f2.8 STF GM OSS Lens Sony

The Sony FE 100mm f2.8 STF GM OSS Lens is an exceptional mid-range telephoto prime lens that offers remarkable creative opportunities, featuring innovative STF (Smooth Trans Focus) optics for magnificent bokeh, and outstanding G Master resolution.

As a fitting addition to the G Master series, this lens combines extraordinary resolution and breathtakingly soft, smooth bokeh that ideally sets off the in-focus subject. The optical design, featuring an innovative optical apodization element and new 11-blade aperture, achieves consistently high performance throughout the image area.

Resolution true to the G Master name

The lens’s spherical aberration compensation, ED (Extra-low Dispersion) glass, and aspherical elements produce extreme resolution and sharpness that fulfill the demanding 50 lines per millimeter MTF requirement that is a basis for G Master optical design. That sharpness extends throughout the image area.

The original Nano AR Coating from Sony suppresses spurious reflections that can cause flare and ghosting, especially in backlit situations, delivering outstanding clarity and contrast with deep blacks in a wide range of photographic situations.

Bokeh doesn’t get better than this

Specifically designed to produce extraordinarily smooth, natural bokeh, this lens features a unique optical apodization (APD) element, a newly designed 11-blade circular aperture, and minimal highlight distortion at the image periphery. Each lens is individually fine-tuned to ensure that the highest G Master standards are realized.

Sony’s original circular aperture design has been improved with 11 blades for even greater circularity. The design and materials have been revised to ensure that an almost round aperture shape is maintained whether open or stopped down, and strict circularity standards are applied to ensure that the full beauty of STF bokeh is achieved without compromise.

Beautiful peripheral highlights

The optical APD element is a special type of filter that exhibits gradually decreasing light transmission towards its periphery, resulting in exceptionally smooth, beautiful bokeh in both background and foreground areas with an absolute minimum of double-edge effects. The lens has been designed to minimize vignetting that can distort highlight geometry at the image periphery, reproducing point light sources with consistently circular bokeh throughout the image.

The lens has a macro ring switch that extends the lens’s range into the macro region, providing 1.87 ft (0.57 m) minimum focus with 0.25x maximum magnification, without any compromise in resolution performance. A DDSSM (Direct Drive SSM) focus drive system provides fast, precise, quiet autofocus, making it an ideal match for modern high-performance Sony camera bodies.

The lens’s optical SteadyShot image stabilization makes it possible to achieve maximum subject sharpness with lower shutter speeds. Additionally, the lens is dust and moisture resistant, with a rubber seal ring at the mount, providing extra protection and reliable operation in challenging environments.

Professional handling and control

Other advanced features that enhance operation for still photography and moviemaking include an aperture ring, switchable aperture ring click stops, a Focus Hold button, an AF/MF focus select switch, and a wide focus ring for sure, comfortable control.

The FE 100mm F2.8 STF GM OSS is an exceptional lens that offers outstanding G Master resolution and unparalleled bokeh, making it an indispensable tool for professional and amateur photographers alike.
