Gossen, Seconic sound interesting, thanks for all the information. Also will consider the Kenko. I will still need some time to make the decision. Got to avoid loosing good images once more as I did last monday night when most of my night exposures at the idustrial heritage site in Dortmund turned out to be failures . Arrghh. The meter of my camera just didn't cut it.
