A reader asked me to test the high shutter speed bokeh of the Hasselblad XCD 90V on the X2D. I made the tests with my recently acquired production version of the lens. For a source, I used an LED flashlight with a 15 or 20 mm aperture at a distance of about 10 meters. That’s… [Read More]

The dubious search for GOATs
It’s always been the case that humans crave simplicity, even when it masks reality.

The basic argument is that we have passed the era of quantum leaps in performance, and that today’s cameras are so capable that you can do almost any… [Read More]
The Nikon Zf has both an AA filter and pixel shift

I don’t know that that’s true, but I can’t think of any counterexamples. Erik Kaffehr found a counterexample, the Nikon Zf. In the spirit of scientific reproducibility, I… [Read More]

This might turn out to be just one more hopeless “there’s something wrong on the Internet, and I must fix it” posts, but maybe it can rise above that. I’ll do my best. In a DPR forum, there is a thread about 4-shot pixel shifting. Under that protocol, which is available on Bayer color filter… [Read More]
