Canon EOS 5D Custom Mode Issue
Luminous Landscape have published news about a design flaw with the Canon EOS 5D’s new custom function.
“Let’s say that my custom setting is for AV mode at f/10 with +2/3EV. I put the camera to C mode and the settings appear as stored. As I continue to shoot, I decide to change the aperture to f8 and change the EV to +1/3. Because the 5D has almost instant power-on, and high battery usage, unlike previous Canon cameras where I would set the power saver to 8 minutes or more, on the 5D I set it to 2 or 4 minutes, so in fact the camera power will time out from time to time when I am idle in relation to shooting. So, I am waiting for the next shot. I see it coming, the camera springs to life almost instantly, but rather than have my new f/8 and +1/3EV setting where I left off minutes ago, the camera apparently says, “OK we are now powering up in the Custom mode, so we will make sure that all the settings are as stored”. GOTCHA!”
