Does your 5d Mark II overexpose when you’re not shooting full manual? Check your focusing screen setting.

I shoot M 95% of the times, gotta use that lightmeter whenever I can, you know. But when I shot Av in the last several months, the images were often bit overexposed. I would usually check the histogram and adjust and didn’t think much of it, but it bothered me that the exposure was a bit off if I didn’t change the EV compensation myself.

I was casually shooting at a park last weekend and it dawned on me that I forgot to change the focusing screen settings to Eg-S after I upgraded the firmware. I got the Eg-S for more accurate DOF display, but it’s a much dimmer focusing screen, and it pretty much requires f/2.8 lenses to be bright enough to see. After changing the focusing screen I changed the settings in the camera so it would meter appropriately, but I guess upgrading the firmware must have reset that setting to the default factory focusing screen, so the processor thought the frame was darker than it actually was and bumped up the EV.

Now the setting is back where it should, I find myself shooting at aperture priority a little bit more.
