I've had my 5D3 for 3 days now and have read the manual and played with settings for hours upon hours.
I really think the way focus points are displayed/illuminated on the 5D3 is broken.
Problem (low light): In low light, the AF point is not visible. It is displayed as a dark square outline in the viewfinder, but in a fairly dark scene, it is impossible to detect. It does not illuminate until it achieves focus on something, and you don't know where on the subject to aim the focus point because you can't see it!
Problem (bright):In bright busy scenes, it can be difficult to see the focus point unless the scene is fairly uniform. The focus point does not blink or illuminate in any way until it achieves focus, so it can be hard to spot until it locks on something. It is easier to see the AF point in bright scenes compared to dark ones, but blinking the AF point when AF starts would be a huge help.
It seems like Canon could fix this through firmware, since the level uses the same mechanism to display information in the viewfinder, but behaves differently.
If you use the level function through the vewfinder, the level indicators are always illuminated when the scene is dark, and turns into a dark outlines when the scene is bright. This is in contrast to the focus points always being dark until focus is achieved (a little late, no?)
I would appreciate any other 5D3 owner's feedback and recommendations for workarounds.
AF Point Display During Focus - Selected (constant) [tried all settings]
VF Display Illumination - Auto [tried all settings]
