Sony recently released 3 compact APS-C lenses and the Sony E 11mm f/1.8 is probably the most interesting. Photography Blog posted its full review which you can read here or you can check out the excerpt below:
It’s more versatile than a slower or narrower optic, ideal for both handheld vlogging to camera where you want to throw out the background and for more traditional landscape and architecture stills photography where you want to stop down the aperture.
The build quality is acceptably good, including full weather-sealing… it doesn’t have any OIS…The E 11mm F1.8 and ZVE10 did prove to be a great match when it came to auto-focusing… fast, reliable and virtually silent…
Optically, the centre sharpness was very high throughout all of the aperture range, even wide-open at F1.8. Edge sharpness doesn’t quite match the center, though, requiring you to stop down to F2.8 to get the best results.
Chromatic aberrations are almost completely absent, vignetting isn’t too obvious, and flare is present but well controlled… some very obvious barrel distortion in the RAW files, which is automatically corrected in-camera for the JPEG files…
…the new E 11mm F1.8 is an excellent, affordable ultra-wide-angle addition to the Sony APS-C sensor mirrorless camera system that offers a lot of bang for your buck…
