Lenses and sensor format

This page lists equivalent lenses for various sensor sizes. Equivalence is made by choosing lenses with same field of view and same depth of field at maximal aperture, for sensors with the same number of pixels, but not the same size.

What does "equivalence" mean here?

We consider that MFD has sensor size the double of FF, which has sensor size the double of APS, which has sensor size the double of Four Thirds.

In conclusion, taking the same picture with equivalent lenses on sensors of different sizes should give the same result. We say "same result" when field of view and depth of field are the same, for the same print size. More precisely, there will be differences between the results: level of detail, bokeh, flare, ... But they depends only on the lens formula, the quality of the glass and the quality of the sensor (and the development process), but not on the sensor size. NB: Richard Butler from DPreview published a long explanation of what "equivalence" means in practice.

Caveat: this "equivalence" is not relevant when speaking of AF capabilities. The size of the AF sensors is usually not proportional to the size of the image sensor, and therefore no conclusion can be made by using this "equivalence". In fact, many APS reflex bodies have the same AF sensors as a FF body (or MF body) by the same camera maker. Therefore the amount of light available to the AF sensors directly depends on the f/N value. This means that a 400/2.8 lens on an APS body will allow a better AF than the equivalent 600/4 lens on a similar FF body. For AF using the image sensor (liveview or mirrorless cameras) the comparison is even more difficult to make.

Why do we look at weight and price?

Weight is a good measure of the difficulty of designing the lens. Price is an interesting characteristic too!

The conclusions that we can deduce from the table below are:
