While boosting precise numbers, camera shutters are often not as good as we think they are. I tested all my camera as described in this article, and published the numbers here. If you would like to help me extend the list, feel free to contact me.

Notes:
(1) Top shutter speed is 1/400, mapped to 1/500 in the chart
