1.4x Magnification — and Up to 2.8x with Teleconverter
The standout feature of the FE 100mm F/2.8 GM is its 1.4x maximum magnification, which goes beyond the typical 1:1 reproduction ratio of most macro lenses. Paired with the Sony SEL20TC 2x teleconverter, the magnification reaches 2.8x, allowing photographers to capture microscopic-level details not visible to the naked eye.
Inside, the lens uses 17 elements in 13 groups, including two XA and two ED elements, to suppress chromatic aberrations and fringing. Sony’s Nano AR Coating II helps reduce flare and ghosting, while the 11-bladed circular aperture produces smooth, natural-looking bokeh.
Autofocus and Video Optimization
Autofocus performance is handled by four XD linear motors, which Sony claims deliver focus speeds 1.9x faster than the FE 90mm F/2.8 G OSS. The lens is designed to track fast-moving subjects accurately and works seamlessly with the Sony a9’s 120 fps burst shooting.
Video shooters also benefit from the design. The FE 100mm F/2.8 GM minimizes focus breathing, operates silently, and includes Advanced Optical SteadyShot stabilization for handheld shooting. Internal focusing ensures that the center of gravity remains stable when mounted on tripods or gimbals.
G Master Build and Handling
As part of the G Master line, the lens is built to premium standards. It features dust- and moisture-resistant weather sealing and a fluorine-coated front element to repel fingerprints, water, and oil.
For handling, Sony has added several pro-level features:
- Sliding focus ring for instant switching between AF and MF
- Two customizable focus hold buttons
- Aperture ring with click on/off and lock functions
- Three-point focus range limiter, letting users quickly restrict focusing for faster acquisition
Despite its capabilities, the lens weighs just 646 grams and measures 147.9mm in length, with a standard 67mm filter thread. It ships with the ALC-SH173 lens hood.
Pricing and Availability
The Sony FE 100mm F/2.8 GM is priced at $1,499 and is available now for pre-order at B&H Photo. The lens is expected to ship starting November 13, 2025.
Sony will continue offering the FE 90mm F/2.8 G OSS Macro, giving photographers a more budget-friendly alternative to the flagship G Master option.
