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… [Read More]

LensRentals has loaned me a Hasselblad XCD 55mm f/2.5 V lens for testing. It arrived today, and I’ll be testing it over the next three or four weeks. One issue the new V lenses have had — at least the 38 and 90 both had it — is odd bokeh at very high mechanical shutter… [Read More]

In another context, the question of the shutter latency of the Hasselblad X2D in mechanical shutter mode came up. I have a way of accurately measuring shutter latency by triggering a camera and a scope at the same time using a remote release on the camera, and measuring the delay between that triggering and the… [Read More]

In the previous two posts. I looked at the out of focus point spread functions for the XCD 90V lens on a Hasselblad X2D 100C camera. The shutter blades were visible. In this post, I’ll look at out of focus images with the lens set at f/2.5 and 1/4000 second. The subjects have both strong… [Read More]

In the last post, I looked at the out of focus (OOF) point spread functions (PSFs) of the Hasselblad XCD 90V 90mm f/2.5 lens on a Hasselblad X2D 100C. I did the test with a new production lens I’d just received. As expected, at high shutter speeds the OOF PSFs departed quite significantly from the… [Read More]
