EOS 5D Mark II and EOS 50D Firmware Updates

February 28, 2012

The latest firmware updates for the EOS 5D Mark II and EOS 50D are now available from the Canon website.

EOS 5D Mark II Firmware Version 2.1.2 and EOS 50D Firmware Version 1.0.9 include the following improvement:

Optimizes the EOS 5D Mark II and EOS 50D’s performance when using certain UDMA 7-compatible CF cards released in February 2012 or later, such as the 16GB, 32GB, 64GB, 128GB, and large-capacity 256GB CF cards in the Lexar Professional CF 1000X series that were sequentially released from late February onward.

When using these CF cards with the EOS 5D Mark II, a card error (Err02) may occur during shooting or when initializing the card. This is caused by a change in the UDMA 7’s control and process method of the above CF cards, that is different from that of the conventional cards, and outside the margin of compatibility of the EOS 5D Mark II (depending on the controller used in the cards).

Although the camera complies with the standards, this update will expand the margin of compatibility of the camera, making it compatible with the target CF cards once the firmware update is installed.
