Hasselblad XCD 90V bokeh at high shutter speeds

February 23, 2024 JimK Leave a Comment

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 and weak specular highlights.

Weak specular highlights

The bokeh is edgy.

Strong specular highlights

The shutter blades are visible.

Strong specular highlight

Same.

Edgy bokeh visible.
