Setup #1

Setup #2

What is this?

This is a simple tool that compares the size of bokeh balls between two camera and lens set ups using a 4K image and equivalent subject framing.

Select the two sensor sizes, lens parameters and subject distance for the first setup. The second set up subject distance will be computed for you.

What you see on the chart is bokeh ball (circle of confusion) size in pixels plotted against the distance behind subject.
