The variances between your two Luna Meters is minuscule. Such could be accounted for by as little as not having first ensured that each meter is correctly zeroed. The angle of acceptances between the Lunas and the EOS in evaluative mode with a 50mm lens would probably acount for the Luna/EOS differences. In theory - light values are absolute but in practice there are abundant variables such as component tolerances, battery diode regulation accuracy, and of course the progressive changes in ambient light which the eye does not reasily perceive. If your EOS gives good results - trust it. Electronic cameras with sophisticated integrated metering seldom produce the readings which are identical with those taken with an external meter - so the EOS is not a good reference point for evaluation of your Lunas. One third of a Stop is innocuous given the lattitude of modern films. It is a difference which you would be unable to detect upon super-lupe examination of the resultant negatives or positives. Sounds to me like you are in good shape to take award-winning photographs. Happy New Year |
