Hi!

I would like to know what is selected for RX1's Transmission Score to decide it's SNR.
T = 2.1 or 2.0?

And if the above selection is not correct, RX1's SNR Score may be changed?
(E.g. If the selected value is 2.0 and the real value is 2.1, the total amount of the light, which reaches to Sensor in real value, is about 10% lower than the selected value)

Hello!

Thanks for your comment.

You’re right regarding the potential bias. In the example you note, it could be close to 14% meaning less than ¼ of Stop.
As we cannot measure the TStop on compact camera we decide to use the aperture, so in this case 2.0.

Best regards,

Emilie
