Heliar 15 exposure

[nobbylon]

Hi all, a question to everyone who uses 15mm lenses on m6 or mp's.
Do you have to compensate for exposure using this lens or does the meter cope ok with the wide view. I'm off to the Himalaya later in the year and I know a stop or so wider is in order for the snow and brightness but wondered if it's necessary to add a bit more? I only got the lens yesterday so not had a chance to experiment!
regards j

Watch out with TTL metering. Big field of view often means big piece of sky. Underexposure is the result. I sold my Bessa L because of this. Use an external meter for landscape stuff.
Or no meter at all.
