5D3 Duplicate image & strange behaviour
7 months ago

I love the 5D3 (mostly) but once again it has done something very strange and I don't know why this has happened.

At a wedding last weekend, my second shooter shot 9 images over a time period of 15 seconds. We shoot Raw + small JPEG so we have both versions of the files. In the middle of the set of images, there are 2 photographs timed 4 seconds apart according to the EXIF data but they are obviously exactly the same image, except that one JPEG file appears slightly darker than the other.

Image 5DMO5311 Timestamp 14:10:07

Image 5DMO5312 Timestamp 14:10:11

The RAW file images are exactly the same, with no difference in exposure.

The EXIF data for both images appears to differ in only 2 values, the time is 4 seconds later for the second image and the lens is listed as 110mm in the first and 90mm in the second. The actual lens used was the 70-200mm f/2.8

Has anyone seen this sort of behaviour before? Is the camera buffer becoming full and causing an issue with writing images to the CF & SD cards? Any thoughts appreciated.
