Sony FE 100mm f/2.8 STF GM OSS Lens

STF™ delivers incomparable bokeh and sharpness

This 100mm mid-range telephoto prime lens is a superb creative tool that offers outstanding G Master resolution plus innovative STF (Smooth Trans Focus) optics for magnificent bokeh. It features fast, precise, quiet DDSSM autofocus, and close-up capability up to 0.25x magnification. Built-in Optical SteadyShot image stabilisation minimizes blur that can occur during low light or macro shooting.

Exemplary G Master resolution and bokeh

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.

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.

Resolution true to the G Master name

With spherical aberration compensation, ED (Extra-low Dispersion) glass, and aspherical elements, this lens boasts 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 image area.

AF that lets you concentrate on creating

A DDSSM (Direct Drive SSM) focus drive system provides fast, precise, quiet autofocus. Fast, unobtrusive AF performance allows the user to concentrate fully on capturing superlative stills or movies. This lens supports both contrast AF and focal plane phase detection AF, making it an ideal match for modern high-performance Sony camera bodies.

Outstanding clarity and contrast

Sony’s original Nano AR Coating suppresses spurious reflections that can cause flare and ghosting, particularly in backlit situations. The result is consistently high contrast and clarity with deep blacks in the widest possible range of photographic situations. (1. Nano AR Coating / 2.Glass / 3.Transmitted light)

Beautiful peripheral highlights

In keeping with this lens’s emphasis on bokeh, it has been designed to minimize vignetting that can distort highlight geometry at the image periphery. Point light sources are reproduced with consistently circular bokeh throughout the image, so that sunlight filtering through or reflecting off leaves, for example, is rendered with serene elegance.

Apodization for unbeatable bokeh

An optical APD element is a special type of filter that exhibits gradually decreasing light transmission towards its periphery. It attenuates the edges of point images, resulting in exceptionally smooth, beautiful bokeh in both background and foreground areas with an absolute minimum of double-edge effects

Get close and explore the details

Because one of the main features of this lens is bokeh, it has been provided with a macro ring switch that extends the lens’s range into the macro region where bokeh can be used to great effect. The macro mode provides 0.57m (1.87 ft.) minimum focus with 0.25x maximum magnification, with no compromise in resolution performance.

11 blades enhance bokeh beauty

Sony’s original circular aperture design has been improved with 11 blades for even greater circularity. Design and materials have been revised to ensure that a 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.

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.

High reliability in harsh conditions

In addition to a rubber seal ring at the mount, the overall design of this lens is dust and moisture resistant for extra protection and reliable operation in challenging environments. Shoot with confidence in light rain or windy conditions.

FAQs

1. What makes the STF (Smooth Trans Focus) technology unique?

The STF technology uses an optical apodization (APD) element that gradually decreases light transmission towards the edges. This creates exceptionally smooth, natural bokeh without double-edge effects, making it perfect for portrait photographers.

2. Is this lens suitable for macro photography?

Yes, it features a dedicated macro ring switch that allows you to focus as close as 0.57m, providing a 0.25x maximum magnification for detailed close-up work.

3. Will the autofocus keep up with fast-moving subjects?

Absolutely. The Direct Drive SSM (DDSSM) focus system is fast, precise, and quiet, fully supporting both contrast AF and focal plane phase detection AF on modern Sony mirrorless cameras.

4. Can I use this lens for pro video work?

Yes, the quiet DDSSM autofocus and switchable aperture ring click stops make it an excellent choice for smooth, silent iris pulls during video recording.

5. Is the Sony FE 100mm f/2.8 weather-sealed?

Yes, it features a dust and moisture-resistant design, including a rubber seal ring at the mount, allowing you to shoot with confidence in challenging Australian environments.
