Conclusion

The E PZ 10-20mm F4 G is an excellent addition to the rather neglected Sony APS-C sensor mirrorless camera system. This incredibly small ultra-wide-angle zoom lens offers a lot of features and performance for a reasonable asking price.

This latest generation lens is notably leaps and bound ahead of the similar Sony E PZ 16-50mm F3.5-5.6 OSS, which dates back to 2013. If you were put-off by the slow to respond power-zoom mechanism on that lens, the new E PZ 10-20mm F4 G should help to change your mind about power zooms in general.

Whilst the PZ mechanism on the FE PZ 16-35mm F4 G is one of the best that we've ever used and will undoubtedly please videographers, it still doesn't quite rival the feel of a mechanical zoom for stills.

You may want to consider the 10-18mm f4 OSS instead, which has a traditional zoom ring and also offers the benefit of built-in stabilisation, although that lens is over 10 years old now and doesn't have the newer optical design of the G-branded lenses.

The other main rival is the Tamron 11-20mm F2.8 Di III-A RXD, which offers a faster maximum aperture but is larger and heavier than the E PZ 10-20mm F4 G.

Optically, the centre sharpness of the E PZ 10-20mm F4 G was very high throughout all of the aperture range, even wide-open at F4. Edge sharpness doesn't quite match the center, though, requiring you to stop down to F5.6 to get the best results.

Chromatic aberrations are almost completely absent, vignetting isn't too obvious, and flare is present but well controlled even when shooting directly into the sun.

The only real notable optical issue is some very obvious barrel distortion in the RAW files, which is automatically corrected in-camera for the JPEG files, meaning that you'll need to do some post-processing or apply a lens correction profile if you shoot using the former file type.

The build quality is very good considering how small and light it is, including full weather-sealing, although you'll ideally want to pair it with an equally weather-sealed lens for full peace of mind (unlike the ZV-E10 that we tested it with).

You'll also ideally want to pair it with a stabilized camera body like the Alpha A6600 as it doesn't have any OIS, which again meant that the non-stabilized ZV-E10 was a less than ideal partner.

The E PZ 10-20mm F4 G and ZVE10 were a great match, though, when it came to auto-focusing, which proved to be be fast, reliable and virtually silent thanks to the dual motor system.

Overall, the new E PZ 10-20mm F4 G is an excellent ultra-wide-angle addition to the Sony APS-C sensor mirrorless camera system that with its power-zoom is more obviously tailored towards videographers and vloggers, but still offers a lot of performance for photographers.
