It appears Tamron isn’t the only lens manufacturer having issues with Canon’s recently-released 5Ds and 5DsR cameras. Sigma has just released a service advisory regarding a firmware update a handful of lenses need to be compatible with the Live View mode in EOS 5Ds and 5DsR cameras.
The incompatibility between a handful of Sigma’s lenses and Canon’s Live View mode first came to light when Canon released its Rebel T6s and Rebel T6i cameras.
The incompatibility meant that the LCD on the back of the DSLRs wasn’t displaying an image when the Live View Mode button was pressed on the camera body. Sigma quickly got to work on a fix and subsequently announced a firmware update that fix the problem.
Thankfully, that same firmware update works with lenses having compatibility issues with Canon’s EOS 5Ds and 5DsR cameras. Sigma says any lenses purchased after May 11th 2015, or already updated to solve the issue with Rebel T6s and Rebel T6i cameras is good to go.
