Sigma has released details of lenses in its current line-up for which both AF and AE will operate without any issues on the new Canon EOS R and Nikon Z7 cameras.
The recently-released Sigma 60-600mm f/4.5-6.3 DG OS HSM extended-range zoom lens is one of the lenses listed as compatible with the Nikon Z7 and Canon EOS R cameras. (Source: Sigma Photo.)
Sigma also states that ‘lenses which incorporate Optical Stabilizer (OS) will work to maximum effect when both the lens’s OS and the in-camera stabilization are switched on simultaneously’. Click here for the list of Nikon lenses.
Cautions have been advised for four lenses in advance of future firmware updates that will correct them. The 24-35mm f/2 DG HSM | Art lens may occasionally stop recording while shooting video. The 50mm f/1.4 DG HSM | Art lens may suffer from intermittent problems with autofocusing when users start to shoot with the subject completely out of focus. The 85mm f/1.4 DG HSM | Art lens may occasionally show overexposure when narrowing down the aperture from f/5.6 while shooting. The APO 800mm f/5.6 EX DG HSM lens requires manual focusing since it is difficult to achieve sufficient focusing accuracy.
Users of Canon’s EOS R camera are advised that with Sigma’s interchangeable lenses, the Digital Lens Optimizer located within the in-camera Lens Aberration Correction function cannot be used and should be switched off. Peripheral illumination correction, Chromatic aberration correction and Distortion correction can operate when the in-camera Lens Aberration Correction function is switched on for the lenses listed here.
When lenses other than those listed are used, Peripheral illumination correction, Chromatic aberration correction and Distortion correction in the in-camera Lens Aberration Correction function may cause images to appear abnormal and should be switched off. When Sigma’s DC lenses are used, the 1.6x (Crop) function will not be set automatically and should be selected manually.
