Hi Christian, A couple of reasons. First, a week or so back JCO made the assertion that by metering thru a lens set at the taking aperture, measuring the actual light transited rather than having the camera essentially calculate the exposure, would result in a more accurate, or precise, exposure. I'd like to see if there's any truth to that, and if there's any practical difference.
Also, I want to compare two similar lenses, one being a Super Tak that can only be used stopped down on K bodies and the other being a K mount version of the lens. It would seem that if the metering styles used were the same (assuming there IS any difference as suggested by JCO), the comparison between the two lenses may be more accurate. However, I doubt that I'd want to shoot that way when making regular photographs. Oh, there's a third reason: I've just a little too much time on my hands right now <LOL> Shel > [Original Message] > From: Christian <[EMAIL PROTECTED]> > > Is there a way to use a K-mount lens on the K, M, or LX bodies with stop > > down metering instead of having to use open aperture? > Just a silly question, and forgive my ignorance, but why would you want to?
