Yes I think that the OM4 is unique among modern cameras in the
implementation of spot metering--at least among the ones I am familiar
with, which would include Contax, late Leica R, and Nikon 8008s/N90s.
I think the reasoning, which is not bad, is that normal center-weighted
metering should be a kind of 'default' which will cover most photo
situations, and spot mode would be used only when conditions would cause
center-weighted to fail.
The opposite situation, which has already happened to me more than once
with other (lesser? :-)) makes, is that you switch the entire camera mode
from matirx or center-weighted to spot, and then forget to switch it back.
Your next photo might be a rush, and you don't see the spot indicator in
the viewfinder, and so blow the shot.
Which design is better? Would you blow more shots by not having the time to
hit the spot button on the Oly, or by forgetting to take a camera out of
spot mode on other cameras? I think the latter...
I would have a slight quibble with your last statement, depending on
camera. If you're perfect, and only have a camera in spot mode when you
intend it to be, _and_ have a body that uses light pressure on the shutter
release as an AE lock, you simply point and lock your reading with the
shutter, recompose, and finish the shutter squeeze. In that case, it's a
one-button operation.
