Looking for recommendations for a small light meter that does well in low light. I have (and like) a Minolta IVF and a Pentax Spotmeter, but want something small to use with my Russian rangefinder. Outdoors I'm OK with sunny 16, but need help indoors. Searching, I read good things about the Gossen Digisix and the Sekonic L-208. Any thoughts on these? Any other recommendations? Again, size and low light capability are key.
