Depth of Field Calculator
Find the near limit, far limit and total depth of field for any focal length, aperture and focus distance, with the hyperfocal distance for your sensor. Calculated in your browser.

-
500 Rule Calculator
Find the longest exposure before stars trail, using the 500 rule (and the stricter 300 and 200 variants) with your focal length and sensor crop factor. Calculated in your browser.
