The following image is from identical crops of 7 frames shot RAW at 2 fps. Crops are 2:1. 2 linear pixels on the image is 1 linear pixel on the original file (If I processed it right). There is a funny bright spot on the fifth frame. At first, I thought it was from a piece of lint on the sweatshirt but on closer examination it looks more like some sort of sensor glitch. All seven frames were shot at ISO 1600, 1/250 at f/8 using an SB800 in TTL mode. Camera body was set to Matrix mode metering. Active D-Lighting was turned on. Lens was a Sigma 8mm full-frame fisheye. The last exposure was noticeably brighter. I attribute that either to the aperture blades sticking or the flash deciding to give a little more output. (I forgot to do this with manual flash.) RAW files were processed with Lightroom. No noise reduction. Same LR parameters for all seven frames. I guess I'll send the NEF to Nikon technical support to see what they say. But I'm wondering what people here think of it.
