In the previous post I reported on the odd bokeh at high shutter speeds of the Hasselblad 55V on the X2D. I repeated the test with the camera’s electronic shutter, making exposures of a LED flashlight about 25 feet away with the camera set to ISO 64, the lens wide open and focused to 0.45 meters. I used 1/200o second shutter speed and 14-bit precision for all the exposures in this post.
Here’s a blowup of a sample image with the flashlight positioned on the lens axis:
No sign of the strange bokeh.
Now we’ll look at mechanical vignetting.
Compare those to the ones for the 38V and you’ll find a lot of similarities.
I did notice one analmoly. There are some banding on these images if you zoom in tight and increase the contrast:
The spacing is not uniform. I’m not sure what the source of the banding is, but I don’t think I can blame the lens. It might be something in the camera, or it could be modulation of the LEDs in the flashlight.
Jim,
You could have used a MAX (images) composite for the mechanical vignetting series, so it would just one image.

Indeed. I’ve done something similar in the past, but the presentation has confused some people.
