Questions, corrections, or a camera whose sensor details you'd like built in? Get in touch.

Email gpcgabriel0@gmail.com and I'll read it. Helpful things to include:

• The camera model, its crop factor, sensor width in millimetres and horizontal pixel count.
• The lens and aperture you were using, and the shutter time where you started to see trailing.
• Any browser or device where the calculator misbehaved.

This is a small, independently run site, so replies may take a little time, but genuine corrections about the formulas or sensor data are always prioritised.
