It has been confirmed that when using the RF 70-200mm F2.8 L IS USM to perform AF shooting to capture a subject at close-range with the focus distance approximately set to the Tele-end (200mm), the image may become slightly front-focused.
To Users of the EF 300mm f/2.8L IS II USM and EF 400mm f/2.8L IS II USM, some specifications for the lens hood have been changed to address this phenomenon.
Canon plans to issue a firmware update that will improve video autofocus speed, accuracy and subject detection performance.
Firmware Version 1.0.8 corrects a phenomenon whereby, during movie shooting, when attached to certain EOS DSLR cameras with the camera’s shooting mode set to M or Av mode, some exposure flicker may happen.
We have determined that a firmware bug may occur with the PowerShot SX740. Find out more about the details of the phenomenon and support plan.
