Not a flame war. A legitimate lens comparison

A little problem ..

No, the 25 1.4 does not equal 50 2.8. It is a 1.4 lens. Comparing the Olympus 2.8 in the wide angles to f4 lenses is also unrealistic. Fast glass is always heavier and more expensive. It doesn't take as much light to properly expose an m43 sensor as an APS-C one. So the apertures values are comparable on a one to one basis while the focal length is not. A 25 1.4 lens is a 25 1.4 lens, period. Put on a smaller sensor it will have a visually greater focal length and depth of field but exposure won't change.

For a given aperture and equivalent focal length, assuming such a lens exists will result in the m43 being lighter. Price will be all over the place. Martin actually gave you realistic equivalents.

Regards,

Kurt
