DxOmark (Click here) tested the new Sony 24-70mm GM lens. Unsurprisingly it is the best E-mount zoom lens from Sony yet.

Given the emphasis on the high-grade components and construction to match the maker’s high-resolution sensors, we had high hopes for the Sony FE 24-70mm F2.8 GM, and we weren’t disappointed. It is the best-performing zoom in the maker’s range and can easily hold its own against the new AF-S Nikkor 24-70mm F2.8E ED VR. However, for edge-to-edge to sharpness, the Sony isn’t quite in the same league as the Canon EF 24-70mm F2.8L USM II, but we still have to add the Sony A7RII to propose a fair comparison with the 50 Mpix Canon EOS 5DSR. Nevertheless, the Sony does have certain strengths — better transmission and lower lateral chromatic aberration than many high-grade primes — and while certainly pricey, it’s still a competitive and tempting addition to the range.

Please note that the sharpness point system highly depends from the sensor resolution. So it’s not fair to test the GM lens on a 36MP sensor camera and the Canon lens on a 50MP sensor camera

DxOmark (Click here) published the Sigma 30mm f/1.4 E-mount lens test results. And as you can see the lens scores and impressive result beating the rest of the APS-C E-mount lens crowd:

The Sigma 30mm f/1.4 DN is an excellent standard prime option for Sony E-mount cameras and ranks at the top for all lenses we’ve tested on the A6000. Sharpness is outstanding, delivering excellent center resolution at all aperture settings up to f/8, with only minimal drop-off in the corners. Vignetting is pretty heavy at f/1.4, as the lens struggles to achieve the same intensity of light across the large APS-C sensor at its maximum aperture, but it improves greatly by f/1.8 and is all but eradicated by f/2.8. Compared to the significantly more expensive Zeiss 32mm f/1.8 and Sony’s own E 35mm f/1.8, the Sigma version is both sharper in the center and more consistent across the frame. Add to that the faster maximum f/1.4 aperture, and the $339 Sigma 30mm f/1.4 DN looks to be a very attractive standard prime option for Sony mirrorless photographers.

Photozone published the full Sony 50mm f/1.8 FE lens review.

It is a bit difficult to come to a conclusion about the Sony FE 50mm f/1.8. It has its moments but there’s also darkness. The resolution characteristic is fairly solid. The outer image field is very soft at large apertures but to be fair – your main subject tends to be near the image center so it’s probably not all that of a deal-breaker in the real life. The center itself is already very sharp and contrasty at f/1.8. The situation is very different between f/4 and f/8 where the quality is impressive indeed. Lateral CAs are generally not an issue. The lens produces some heavy vignetting at maximum aperture. Some may like this effect as a creative element but those who don’t may prefer to correct this either via camera setting or in your favorite RAW converter. Otherwise you should stop down by about 2 f-stops. The quality of the bokeh is fairly good with smooth highlight discs, albeit with a bit of outlining, and a smooth albeit asymmetric general blur. A fair share of bokeh fringing is also present (see one rather extreme example in the sample image section).
The mixture of good and bad continues on the mechanical side. The build quality is actually very decent and in line with most modern 50mm f/1.8 lenses. There’s a pain point though – the auto-focus. Some lenses get nicknames and we’d like to call this one “Captain Slow” (we hope James May doesn’t mind …). It is embarrassing to witness such an AF in a brand new lens really.

Which brings us the question whether this lens is worth it? We are not convinced.
