What is the Sony Ultra Wide Converter SEL075UWC?
The SEL075UWC is a dedicated ultra-wide converter designed specifically for the FE 28mm F2 (SEL28F20) lens. It attaches to the front of the lens to provide a 21mm angle of view on full-frame cameras, with dedicated optics and a visually matching design.
Which lens is the SEL075UWC compatible with?
The SEL075UWC is a converter dedicated to the FE 28mm F2 lens (SEL28F20). You can verify camera-to-lens compatibility using Sony's compatibility tool at support.d-imaging.sony.co.jp/www/cscs/lens_body/.
What focal length and angle of view does the SEL075UWC provide?
When attached to the FE 28mm F2, the converter delivers a 21mm focal length and roughly a 92° angle of view on full-frame cameras. On APS-C E-mount bodies, it provides approximately a 31.5mm equivalent field of view with about a 68° angle of view.
Does the SEL075UWC control distortion well?
Yes. Independent tests report very low barrel distortion (around 0.7%) for a wide converter, and the distortion pattern is uniform enough to make software correction predictable and effective. Sony cameras also correct distortion automatically in JPEGs.
Is the SEL075UWC good for architecture and interiors?
Yes. When used with in-camera correction or proper lens profiles, the SEL075UWC can render straight lines accurately, making it usable for architecture and interior photography. RAW files may need post-processing, but the geometry corrects without unusual artifacts.
How does the SEL075UWC affect aperture and image quality?
The effective maximum aperture becomes f/2.8 when attached. It's designed to maintain high resolution across the frame with good central sharpness and controlled chromatic aberrations, though corners may be softer.
Is the SEL075UWC weather resistant?
Yes. It features a dust and moisture resistant design that matches the weather-resistant construction of the FE 28mm F2, making it suitable for outdoor reliability.
Does the camera detect the SEL075UWC automatically?
Yes. The camera automatically detects the converter via an internal sensor system and records the appropriate EXIF lens data, such as focal length and aperture.
How much does the Sony Ultra Wide Converter SEL075UWC cost?
MSRP is listed as $299.99. Given that, these models can go on sale from time to time, and there are several other opportunities to save on price like through their group discounts for education, healthcare and military/veterans (ID.me & Unidays) along with their free loyalty program that gives up to 5% back in points.
Can I use filters with the SEL075UWC?
The converter has a built-in shallow petal hood and no front filter thread, and the original 28mm filter thread cannot be used when the converter is mounted.
