Hello, and sorry if I interrupt something.
I don't think OM-4(Ti) has 'real time' spot. I wouldn't have sense to have it
as the spot is always pointed towards the middle of the scene, which is not
always
the interesting point to take a measure of.
'Real time' measures have only sense with average or 'intelligent' matrix light
meters.
Regards,
Leopoldo

And then you said...
>>No it does not. A simple test can reveal the OM-4(Ti)'s real time spot
metering. You don't even have to leave the house to perform it :-).
Take a piece of black cardboard, and cut a circle from it, the size of a
small plate. Tape this black circle on a window during daytime. Take your
OM-4(Ti), mount any lens in the 28-100 mm range, put it in Auto mode, take a
low angle and point the spot-centre towards the black circle so that only
the sky and the circle are part of the 'composition'.
Take a centre-weighted metering; this could be maybe 1/500 with the
dominating sky. Now take a spot metering of the black circle. This could be
maybe 1/60. Clear the spot-metering, move the spot-centre away from the
black circle and take a spot readig from the sky. This would be (almost) the
same as the centre-weighted meterig, 1/500. Now while retaining this spot
value, move the centre back towards the black circle. The second, moving
diamond will move towards 1/60, representing the previous EV value of the
black circle. Voila, real time spot metering. >>
Without commenting further on the merits of either camera method, your
demonstration is not what was meant. What was meant is that with lesser <g>
cameras, it is often possible to switch between metering systems and leave
the camera there. One would therefore not have to press a spot button,
clear it from memory, etc.
