Sony A1 Sensor Review (DxOMark): “Speed and Quality in One”

Kevin Carter has just posted a full review of the newly released Sony Alpha a1 (Amazon/ B&H/ Adorama) at DxOMark.com. Sony Alpha a1 achieved an overall sensor score of 98, which puts it in 9th position in their overall sensitivity ranking (including medium format) and in 7th place for full-frame 35 mm. That places Sony A1 fractionally behind the Sony A7R IV and Nikon Z7 II at 99 and 100 respectively, and just slightly in front of the Canon EOS R5 at 95 points by less than 0.2EV in overall sensitivity.

landscape 14.5 14 14.8 14.7 14.6
sport 3163 3434 3344 2841 3042

Below is the conclusion, “Sony A1 combines the best of the A9, A7R, and A7S series in one package, and naturally that doesn’t come cheap… Sony A1 has a high-resolution 50 MP sensor that produces exemplary images and is practically identical in performance to existing high-end sensors which feature far lower pixels counts, such as those found in the superb Leica SL2-S and in Canon’s equally superb flagship EOS-1DX Mark III. Combined with the wide range of available native-mount lenses, its sensor makes the Sony A1 a highly attractive option for professionals working in a wide range of genres and markets, and will no doubt be on the wish lists of a tranche of enthusiasts and amateurs alike...”
