A perfect macro prime for everyday use
This versatile 50 mm “normal” macro prime lens for full-frame sensors is ideal for everyday photography as well as capturing impressive 1:1 macro images. You can get as close as 16 centimeters from the subject while the normal angle of view makes it possible to include background elements for added creative freedom. Controls and operation are optimized for easy, efficient close-up shooting.
Get close for spectacular macro
Focus as close as 16 centimeters with 1:1 macro capability. Shoot subjects without having to move the camera back to find a usable distance. A great lens for everyday situations.
Excellent image-wide sharpness and bokeh
A high-performance optical design that includes an ED glass element minimizes chromatic aberration, even when shooting close, contributing to outstanding corner-to-corner sharpness. Out-of-focus backgrounds are beautiful too, with a circular aperture mechanism helping to produce smooth, natural-looking bokeh that can make your subjects stand out.
Compact, lightweight design
Max. 70.8 mm diameter and 71 mm length with a total weight of only 236 grams 8.4 oz for outstanding mobility and easy handling. This lens is a perfect match for the compact α series, and an ideal choice for everyday use.
Magnification and distance scales
Magnification and distance scales enhance convenience with precise numeric indications that can be an important aid in achieving the desired magnification and focus for macro photography.
Comprehensive control for easy macro
A focus-mode switch can be used to quickly switch between manual and auto focus, adapting easily to any macro opportunities that arise. A focus-range limiter sets the lens’s focus range for the fastest possible AF operation, and a focus-hold button freezes focus wherever it is pressed for controlled, stable shooting.
For snapshots as well as macro
The lens’s “normal” 50 mm focal length makes it ideal for shooting scenery and portraits as well as close-up subjects. An aspherical element carefully compensates for field curvature, maintaining top image quality from image center to periphery.
Reliable in challenging conditions
A sealed dust and moisture resistant design provides extra protection and ensures reliable operation in challenging environments. Shoot with confidence in light rain or windy conditions.
Lens Configuration
Impressive optical performance for Sony cameras, precision engineered for versatility and reliability in a wide range of applications.
MTF Chart
MTF (Modulation Transfer Function) describes how well a lens can reproduce fine details, measured as the degree of contrast achieved between finely spaced lines.
