The new PME45 meter finder offers both spot and center-weighted, but the Hasselblad site doesn't indicate the size of the spot. Older PME45s, like the one I have, were center-weighted only. It uses a 3v Lithium, CR-2 battery, and eats them rather quickly, as I recall. For the premium price of the metered finder, I don't think it's worth the price. For the difference in price from the non-metered finder, you could buy a couple of good multi-function meters, and hire a member of the Swedish Bikini Team to take readings for you.
