| p.1 #14 · D600 exposure varies between 2 shots same settings |
The aperture lever look ok to me and I do not have any of the dynamic range, highlight stuff turned on. It may need a trip to Nikon.
Assuming there's nothing wrong with the sensor, the only way to get varying exposures in M from one shot to the next is if either the shutter or aperture mechanism is malfunctioning. Of the two the aperture is easier to verify. Shoot a scene with shallow DOF, where you'll be able to visually distinguish a stop difference of DOF. Take a sequence with the same shutter/aperture, using an aperture 1 stop away from wide-open. For two images with different exposures check to see if the DOF is different. If it is then the aperture lever is malfunctioning, otherwise it's the shutter.
