Canon Upgrades EOS-1D Mark IV Performance

by Johan on July 6, 2010



Canon has decided to upgrade the EOS-1D Mark IV by releasing the new firmware update version 1.0.8. The new firmware fixes a phenomenon in which the set aperture moves unexpectedly when shooting movies in manual exposure mode using some Canon lenses (such as macro lenses). What’s more, the firmware update version 1.0.8 also corrects misspellings in the French and Spanish menus for applicable products. You can download the Canon EOS-1D Mark IV firmware version 1.0.8 here. [Canon]
