Sigma Issues Lens Alert for Canon’s 1D X Mark II

June 2, 2016

If you own a Canon 1D X Mark II and have been experiencing some underexposure when using your Sigma glass, read on.


Sigma UK has issued an advisory for three lenses–the 20mm F1.4 DG HSM Art, the 35mm F1.4 DG HSM  Art and the 85mm F1.4 EX DG HSM--saying they're not fully compatible with Canon's new flagship DSLR, the 1D X Mark II.

When mounted to a 1D X Mark II and when using center-weighted average metering or evaluative metering those lenses can result in improper exposure.

Fortunately, a firmware fix is in the works to correct the issue, though exactly when it will be available wasn't spelled out.
