Sigma has issued two DC DN f/2.8 zooms and three DC DN f/1.4 primes for the RF-S Canon mirrorless APS-C cameras: the 18-50mm f/2.8 DC DN, 10-18mm f/2.8 DC DN, and f/1.4 primes at 16mm, 30mm and 56mm.
The 18-50mm f/2.8 came out last summer and its R7 profile came out two months later, after many requests from me - and Sigma sending them a copy to test.
The rest came out in the fall, including the 56mm f/1.4 the first week of December (which I bought) but over four months later, and many requests from me, DxO has issued no profiles for any of the other Sigma RF-S lenses.
These lenses have already been profiled by DxO for Sony, Fujifilm, and Leica mirrorless APS-C bodies, and even in the EF-M mount for Canon’s earlier M series mirrorless APS-C bodies, including the M6 Mark II, which has the same resolution sensor as the R7.
I can’t understand their foot-dragging on this. Maybe if others here also submitted requests through their “Supported Cameras” page they’d do something.
