Hey,
I've got a little problem with shooting timelapses: I use a Sony a7s with adapted Canon lenses (17-40mm f4L, 70-200mm f4L). When I'm doing a timelapse sequence (using an external Intervalometer) sometimes a few photos in the sequence are too bright and appear to be shot at f4, although I set the camera to use a smaller aperture. The EXIF data still says that the photo was taken at the correct aperture but apparently the lens didn't stop down properly for that photo. Does anybody know what I can do against that? Does that have something to do with the adapted lenses? I tried two different adaptors (from Commlite) and I get the problem with both.
