>The one big variation is whether the camera meters at the taking aperture (early Spotmatics, or later models when used with older lenses), or whether the lens remains at full aperture while metering. This makes absolutely no difference in *how* you adjust the camera (you still have to position that needle), but it makes a big difference in how easy it is to do it in low- light situations.
Things are getting clearer all the time. But *which* way is easier in low light situations? Marnie :-)
