Boo-yah!!! DxO Tests show that not only is Sony FE 100-400mm GM OSS lens the SHARPEST tele-zoom lens in its class – it’s even sharper than $12,000 Canon 200-400mm L IS USM lens!
Quoting DxO Labs:
“Sony’s longest lens in the lineup, the Sony FE 100-400mm GM OSS lens performs exceptionally well, especially given that it’s a tele-zoom. It has very high levels of sharpness, low fringing and vignetting, all helping it achieve a high DxOMark score. In terms of optical performance, it outperforms the popular Sigma 120-400mm F4.5-5.6 and the Canon EF 100-400mm 4.5-5.6L IS II, and ranks alongside a couple of the pro favorites — the Sigma 120-300mm F2.8 EX DG on the Nikon 800E, and the much pricier Canon EF 200-400mm F4L IS USM. It’s even not far behind the latest iteration of the Sigma 120-300mm F2.8 (the DG OS HSM S model). More interestingly perhaps, in terms of sharpness levels, it outperforms them all, even those mounted on the Canon EOS 5Ds R with its higher pixel count sensor.”
“Sony’s new FE 100-400mm F4.5-5.6 GM OSS stands out not only for its seismic shift in sharpness, but also for being not much different in size to the FE 70-200mm F2.8. Best of all, perhaps, is that for once there’s a tele-zoom that offers seriously impressive image quality at that prized 400mm focal length.
The Canon 200-400mm L IS USM lens is an excellent benchmark – but this shows what many of us have already seen – the Sony FE 100-400 GM is SHARPER!
