[QUOTE="DocPit, post: 427497, member: 38004"] Hello Everyone, I'm hoping someone can help me figure out why the metadata produced by my Nikon D3200 often specifies settings that are not possible. I've been running manual flash tests, using a Nikon D3200 with a Tamron 150-600mm f/5-6.3 zoom lens, a Tamron 2x telextender, and two vintage Vivitar 283s synched to the Nikon hot shoe via a Wein SafeSync. With the 2x telextender, the focal length ranges from 300mm - 1200mm, and the aperture range for the Tamron goes from f/5-6.3 to f10-13. But the metadata will specify, for example: frame #2: f/2.2, 1/20, ISO 400, 10mm (f/stop and focal length out of range) frame #3: f/13, 1/320, ISO 2500, 1200mm (all metadata in range) frame #5: f/10, 1/125, ISO 6400, 10mm (only focal length out of range) I can't identify any pattern. Can anyone tell me under what conditions the camera will specify settings that are not within the range of possible settings? [/QUOTE]
