BEST MACRO LENS FOR IPHONE 8 HOW TO

These cameras automatically correct for the effective f-stop and show it on the LCD display. Regarding the aperture, on the calculator, set "YES" to "Aperture is already an effective f-stop" if you're using a Nikon camera. It is calculated as Total depth of field × 0.8.

Safe step size for stacking (20% image overlapping): It's the maximum step you need to move the camera on a focus slider in order to capture the whole subject in focus when applying the focus staking technic.

Smallest Subject which can fill the image: the size of the smallest subject that can fit in the image.

Total depth of field: The distance between the farthest and nearest points which are in acceptable focus.

Then, effective aperture is: (1+ Magnification/Pupil Magnification).

For longer focal lengths (macro lenses), you need to take into account lens Pupil Magnification.This works pretty well for focal lengths around 50mm. This calculator computes effective aperture as: lens aperture × (1+ Magnification).This means that an aperture of f/2.8 becomes more like f/5.6. At 1:1 magnification, you lose about 2-stops of light. Effective aperture: Magnification has the “effect” of closing the aperture.Magnification: The proportion between the size of the subject image on the camera sensor and its real size.Just introduce camera model, aperture, focal length, focus distance, pupil magnification and extension tube (in the case you use one) to calculate: This macro depth of field calculator takes into account magnification and pupil magnification to give you a good approximation of depth of field values in macro photography. For focal lengths around 50mm, not taking into account pupil magnification may work pretty well.īut, when using long focal lengths, such as 105mm or 180mm, you should take into account pupil magnification to get more accurate results. This is the result of dividing the diameter of the exit pupil of a lens by its entrance pupil diameter. This CoC results from the combination of the selected camera sensor and the following viewing hypothesis: Most depth of field calculators you find online give DoF values based on an accepted Circle of Confusion (CoC).
