Are the black frames intermittent?

If so, this looks like it could be a shutter, mirror, or sequencing unit issue.

If you don't want to spend as much as Nikon charges, it is worth having an independent repair shop evaluate it, as it is now out of warranty, right? I can personally recommend Midstate Camera Repair in Warwick, RI. I'm a satisfied customer. Their name gets tossed around here every so often.

Check the battery and electrical contacts first.

At this point I believe it has to be a battery issue until I see it occur again. I shot a

Sure is nice to hear your good news.

The reason I suspected 99.99% battery issue was because of what you wrote and my little understanding of how the shutter, sensor, micro-processor and memory works.

The electronic shutter will trip as long as the capacitive charge pump that is hidden in the grip of the DSLR reaches a certain set voltage level, it than release the latch that sets off the spring load shutters.

While the shutters (1&2) are open, the processor will process the signals from the sensor and store them in the Flash memory. While this is going on the set voltage level must be kept stable without rippples, but in case of unstable voltage level the process can be corrupted, interrupted or even reset. If that is the case the camera will not know, but the shutter will be ready to fire once again once the voltage level in the charge pump reach the set limit.

Note: The power requirement for the charge pump is a lot less than what is require for the sensor, processor and memory combine, and that is why it is causing what looks like a dark frame problem.

Hope your next test will be as sucessful as your last one.

Best of Luck!
