When testing and evaluating a camera, whether that’s a digital photo camera, video camera or digital cinema camera it is always useful to have a test chart or 2 (or more). While printing a chart at home isn’t always the best way to go, comercial charts can be very expensive to buy. So below is a link to an ISO 12233 chart, a Zone Plate chart and a Siemens Star chart that you can download for free and print at home. You will need a good printer and good quality photo paper for the best results.
For the ISO 12233 chart I divide this into quarters, print each 1/4 and then join them back together to make a larger chart.
The zone plate and siemens charts should be printed as large as possible, but in use they would not fill the frame, perhaps only a small part of the frame depending on the resolution of the camera you are evaluating.
I have not included any color charts or grey scale charts as it will be extremely difficult to know whether the colors or shades of grey your printer produces are actually correct, making the chart invalid.

I have been using a $5 bill as a focus chart. There are very fine lines around the presidential portrait, and the whole piece of currency, that makes it good for comparing resolution of lenses.
