The CDC01 is the most classic chart in my toolkit — a solid all-rounder. It features a bit of everything: Siemens stars, resolution lines, numeric blocks — all laid out in a clean, symmetrical design. This is my go-to chart for testing lenses.

The CDC02 packs in extra Siemens targets for accurate focus checks (front and back), a variety of line targets to assess sharpness and aberration, and a super symmetrical layout.

The CDC03 was built with high-res sensors in mind — think 8K and beyond.

The CDC04 is the Siemens target chart. Great for focus tests on ultra high-res sensors thanks to the fine detail.

The CDD01 is the distortion chart. Just blocks — nothing else. Designed to help you spot barrel, pincushion, and mustache distortion fast. Clean lines, evenly spaced, so any bending or warping jumps right out at you.
