Sony E 24mm 1.8

The Zeiss Sonnar T* E 24mm f/1.8 ZA is a great little lens - if you can get a well-centered sample at least. In terms of resolution, it delivers everything that you expect from such a high-priced lens. It's already very usable at f/1.8 and razor-sharp at optimal aperture settings. Lateral CAs are low. A Zeiss-weakness is, once again, vignetting so auto-correction is a good idea here. Auto-correction also helps to eliminate the slight pincushion distortion that is present in RAW mode. The bokeh is a bit sub-par but this applies to most wide-angle lenses. The build quality is top-notch in terms of materials and smoothness of the focus ring. However, there is no weather-sealing which is really a pity at this price point. It's worth noting that the lens can focus down to an object magnification of 1:4 (0.16m) which is interesting for dramatic close-ups. If you want a high-performance, yet low-profile wide-angle lens for your APS-C Sony camera, the Zeiss is an obvious choice. The pricing is a bit of a problem though. Sony has always charged a premium for Zeiss-branded lenses but at close to 1000USD/EUR it's really over the top here. For comparison - the Sigma 16mm f/1.4 DN DC sells for just 400USD/EUR and that's an even wider and faster lens. And if you can live with something bigger, the new Sony 24mm f/1.4 GM is probably the better and more flexible alternative.
