I'm looking at metering alternatives for when using my Hasselblad CM500. It occurred to me that I might already have what I need ... My Canon G3 ... It's metering readings match those of my Pentax ME Super (which is accurate enough for my style of shooting) and it has the added advantage of spot metering and digital capture if wanted/required. And it's not much bigger or heavier than the dedicated meters such as the Gossen Lunar Pro SBC that I have been considering. Any thoughts?
