Just for a little perspective, there is a fellow forum member and large format hiking buddy (who shall remain nameless) who purchased a new digital light meter before a previous hike... Pity it was trapped inside a canon 7d, but still, it metered well, and also replaced his Linhof viewer at the same time... Quite a useful accessory really... And you can't tell me his chromes looked any worse for not using a composition card and a sundial...
