Canon has released a firmware fix to the dreaded "lock up" issue that has plagued some 1D X Mark III users, making the camera unusable for high-speed shooting. Firmware version 1.1.0, released earlier today, fixes the problem and adds a few additional features at the same time.
A couple of weeks ago, a number of Canon 1D X Mark III users began reporting that their cameras were locking up mid-burst, making them unusable for any sort of high-speed photography. Canon has now confirmed the issue, has found a workaround, and is preparing a firmware fix.
After receiving several complaints from professional and private sources alike, Nikon has finally stepped forward to admit to and address the reported "lock up" issue with its new D4 and D800 DSLRs. The issue, which Nikon maintains only affects "a small number of D4/D800 users," causes both cameras to lock up unexpectedly and up until now could only be "fixed" by removing and reinserting the battery.
