Sigma 35mm f/1.4 HSM lens group classification
The 5D Mk III's user manual says: "Although the camera has 61 AF points, the number of usable AF points and focusing patterns will differ depending on the lens. The lenses are thereby classified into eight groups from A to H." As this lens is not made by Canon, I wonder which group it belongs to. If A group, there should be 5 dual cross AF point available, but who knows. Exif tool identifies this lens as Canon EF 16-35 f/2.8 or Sigma lens. What's your opinion?
