Focus Chart - Printable | CSC01
The ultimate full-frame reference tool. This chart is a dense, comprehensive package for stress-testing every aspect of a lens: sharpness, distortion, and chromatic aberration. Download, print, and gain immediate confidence in your glass.
Industry Standards:
Each chart utilizes essential photographic targets, including Siemens Stars (for identifying limiting resolution and aliasing), Numerical Blocks (for clear resolution values), and Linear Patterns (for checking astigmatism and distortion). These tools give you objective data, not guesswork.
The Professional Edge:
Custom Branding Available
We offer a sleek, unobtrusive custom branding option to integrate your company logo or name directly onto the chart. This is essential for rental houses needing asset tracking, production companies establishing proprietary testing standards, or DITs who require immediate, recognizable documentation of their lens test reports. Maintain professionalism and streamline your workflow.
How to print a top-quality focus chart
To get the best possible print, ask your local print shop if they can print at 1200 DPI. This gives you sharp detail across the whole chart. Also, go for matte paper — it helps avoid glare from overhead lights.
My print shop here in Haarlem prints it on a 5mm thick board called Vorex. It's super handy — you can just stick it to the wall with double-sided tape or a screw. No frame needed.
In a nutshell:
1200 DPI (or as high as they can go)
Matte paper (Tecco PM230 is great, but can be pricey)
Thick paper – at least 230 g/m²
A1 size (your print shop will know what that means)
