I'm shooting with a Vario Switar 100 POE with a Bolex RX5, but the built in exposure meter of the lens is dead (tried new batteries, but the contact seems to have been badly corroded away, so no joy), which means I'm working from a manual exposure meter. I wondered if any exposure compensation might be required when closely zoomed in? I would assume being zoomed in reduces the light entering the lens, so would have to open it up a little? Does anyone have any experience of this?
Sadly, I'm not right now in a position to develop any test footage.
I'm using a bolex lightmeter (which has built in compensation for the reflex viewfinder), taking incident lightreadings outdoors, mainly shooting high contrast light/dark subjects. Shooting on double-x 7222 b/w neg stock.
Many thanks,
Richard
