Sony FE 100mm f/2.8 STF GM OSS E Mount Lens

Sony FE 100mm f/2.8 STF GM OSS E-Mount Lens

Sony offers this versatile prime lens to bring bokeh and sharpness in one neat package. Your new go-to lens for portraits, weddings and fashion utilizing both contrast AF and focal-plane phase detection to make sure your image is sharp as a tack. The high-precision Direct Drive Super Sonic Motor (DDSSM) brings you in focus with exceptionally fast, quite and accurate AF. Built-in ring-switch on the lens barrel gives you macro capabilities, bringing you the benefits of two lenses in one.

Also here to please the moviemakers, the responsive manual aperture ring offers an "Off" mode to give you the least aperture operation clicks possible for silent transitions and beautiful videos.

Unique Smooth Trans Focus G Master

G Master design combines extraordinary sharpness and smooth bokeh in one lens. STF (Smooth Trans Focus) realizes an ultimate collaboration of impressive bokeh and high resolution that only Sony can offer. It is not easy to achieve spatial frequency of 50 line pairs per millimeter at a lens' widest aperture and produce smooth beautiful bokeh at the same time, but that is Sony's baseline for G Master design. Unprecedented resolution and other demanding design parameters yield outstanding reproduction of the most detailed subjects and scenes with superior contrast throughout every frame. G Master resolution is simply the highest in its class.

Defocused Highlight Distortion Eliminated

A unique feature of the STF lens is the special optical apodization (APD) element which produces exceptionally smooth background and foreground bokeh. The APD element acts as a graduated neutral density filter, with light transmissivity highest at the center and then gradually decreasing towards the periphery to ensure extraordinarily smooth bokeh. The APD element ensures equally smooth foreground and background defocus, without double-line effects.

Selectable Macro Mode

Besides being a perfect portrait lens, the Sony FE 100mm f/2.8 incorporates a convenient ring-switch on the lens barrel to select from full range to a macro range. With close-up focus capability up to 1.87ft. min. and 0.25x max. magnification. It's like having two lenses in one.

Blur Reduction

High-performance Optical SteadyShot image stabilization is built right into the lens for sharp, blur-free images with a wide range of subjects. The stabilization lens is driven by a linear motor for fast, precise stabilization. Additionally, 5-axis image stabilization becomes available when used with α series cameras that feature built-in image stabilization.

11-Blade Circular Aperture for Gorgeous Bokeh

The 11-blade circular aperture maximizes the beauty of this large-aperture prime-lens, contributing to impressive images in which the subject stands out against a smoothly defocused foreground and background bokeh as well as perfectly round points of defocused light. Conventional aperture blades have flat sides creating unappealing, polygonal shaped defocused points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.

Aspherical Lens with Super ED Glass and Muiltiple Coatings Reduces Spherical Aberration, Flare, & Ghosting

Aspherical lens design dramatically reduces spherical aberration while also reducing lens size and weight. Spherical aberration is a slight misalignment of the light rays projected on the image plane. This is caused by differences in refraction at different points on conventional spherical lenses which degrade image quality in large-aperture lenses. Specially shaped "aspherical" elements near the diaphragm restore alignment of light rays at the image plane, maintaining high sharpness and contrast even at maximum aperture and can also be used at other points in the optical path to reduce distortion. Well-designed aspherical elements can reduce the total number of elements required in the lens, thus reducing overall size and weight.

The refined optical design includes an ED (Extra-low Dispersion) glass element which dramatically reduces chromatic aberration and provides superior contrast across the entire image, even at large aperture settings, resulting in corner-to-corner sharpness.
