Product Features

Sony 20mm f/2.8 Alpha E-mount Lens (SAL20F28)


The 20mm f/2.8 Alpha E-mount Lens from Sony is a compact 20mm prime lens for the Sony NEX line of APS-C sized mirrorless cameras. Its 35mm focal length equivalent is 30mm which classifies it as a wide-angle lens with multiple applications. Its maximum aperture of f/2.8 is bright enough for low-light capture and shallow depth of field imaging and its optical design consists of three aspherical elements which correct distortions and aberrations and provide clear, high contrast, detailed images. A smooth, quiet internal stepping motor is used for both focus drive and aperture actuation and makes this lens ideal for shooting video. Less than an inch long and built with aluminum alloy, it is both compact and durable. Autofocus and Direct Manual Focus, which allows for precise manual focus even in AF mode, is supported for both photo and video. 

Wide-Angle Focal Length and Fast Aperture
With a 20mm focal length (35mm equivalent of 30mm) and a bright maximum aperture of f/2.8, this lens provides a wide-angle focal length ideal for numerous applications and shooting situations. Its maximum aperture is fast enough for effective low-light shooting and shallow depth of field imaging.
Compact Aluminum Design
The aluminum alloy lens barrel is inlaid into a molded-plastic component for a lightweight yet durable construction. It measures 0.8" (20.4mm) in length and fits well with the compact design of the NEX-system cameras.
Image Quality
Three aspherical lens elements correct distortions and aberrations and richly detailed images with high resolution and excellent contrast are possible even in the periphery of the frame.
Smooth, Quiet Focus and Aperture Actuation
An internal stepping motor is used for focus drive and aperture actuation which results in a smooth, low-noise operation ideally suited for shooting video.
Direct Manual Focus
Direct Manual Focus allows for precise manual focusing at anytime, particularly useful for critical focus when shooting video.
Circular Aperture
This lens features seven aperture blades that form a near circle which provides a pleasing defocused circular effect (bokeh) on the background of your image when the aperture is set wide open.
This is f/2.8, image resized to 1800 pixels to make it manageable - as you can see the bottom left and bottom right are blurred (not soft, actually blurred). When you flip the camera, the problem moves to the top of the frame - it seems the QC issues are present here.

The SAL20F28 is a circular aperture lens with superior optics to suppress image aberration across the focusing range. It is also able to suppress image aberrations from infinity to the minimum shooting distance of just 20cm. At smaller apertures, the SAL20F28's Depth of Field is so great that it effectively becomes a pan-focus lens with the amazing ability to capture both foreground and background elements with equal sharpness and clarity.
