A reminder for some memebers as to what the F stop is all about.

To all who continue to accuse me of all kinds of photographic sins...

Or why the light meter doesn't care.

Hello, again.

Let me repeat my point:

Given the same light source conditions and ISO setting the illumination, measured in lumens, received by any size of sensor is equal across all formats (no Ifs , no buts) , when cameras are set to the same A , S, ISO values. So, in practical terms this means, that the illumination received by my tiny c7070 at 125/5.6 and ISO 100 is exactly the same as on the so called FF sensor camera set to the same values. This will result in the same picture brightness/darkness , subject to DR and noise differences.

Please, do not feed me things like "amount of light", "sensor area", "light power" , "bigger lens opening" etc. and try to operate , using known physical terms and concepts.

Here is the final word. Please, do me a favor:

get hold of ANY light meter (be it a 40 year old analogue one, or a modern Sekonic) and look at it carefully and then tell me , where do you see "Canon FF" or "Olympus c2020" or Fujifilm X100s ??? And then prove me wrong.
