RE: Overexposure problems – 5D and new 24-105mm f/4.0L
I was like a kid on Christmas day when UPS showed up with a new 24-105mm f/4.0L lens today. This lens was intended for my new-to-me 5D body.
Needless to say, I was immediately disappointed at the results. All of my exposures, no matter the ISO, shutter speed, or aperture setting seem to be overexposed by about 1+ stop; maybe even as much as 1 and 2/3rds.
At first, I couldn’t believe my eyes, so I tested it with the 16-35mm f2.8L at the same focal length. Then I went to a friend’s house and had him look at it too. We even tried his 17-40mm f/4.0L at the same focal length. Same results… the new 24-105mm is overexposing. I tried everything I could think of, including resetting all of the 5D’s settings back to factory default. But I'm still having the same issue. Your comments/suggestions would be greatly appreciated.
Below are results of a side-by-side comparison that represents tests with the other lenses we tried.
