Hi,
> Oooooops, my mistake. It was only wishfull thinking.
It seems we both unintentionally caused some confusion [something wrong in
Amsterdam yesterday that caused us to not think correctly?!?] :)
I just re-read one of my own replies, and had to chuckle at yet another
great mistake I typed in it, and which much to my surprise wasn't pointed
out by anyone on the list (yet), so I'll be honest and do it myself. In said
reply I first wrote:
"Well, I use the memo function very often in spot mode (in which I'm certain
that the first exposure has the same exposure time as the subsequent ones
stored in memory, since the spot mode enforces these spot metered values,
instead of using the OTF metering), which works fine."
And then a bit further down in the same message I contradicted myself by
writing:
"To me this does make sense. In spot mode you do perform an OTF reading, BUT
only of the centre 20f the frame. You then actually override the camera's
CAM measurements by enforcing the camera to use the value measured in spot
mode. Hence, if you use the memory function after having taken say 3 spot
readings you will have the averaged value of these three readings stored in
memory (as desired), AND you will still have the same values set for the
first picture you're taking, so if you use the memory function or not, the
CAM measurements will still be overridden by the spot measurements."
So, _almost_ correct, but of course in spot mode the light isn't actually
measured OTF, but off the mirror (otherwise you would get some interesting
overexposed 2% big dots on your pictures whenever you perform a spot reading
:) )...
I apologise for having caused the intitial confusion (and for this typo
(thinko?)), so now to get back to some of the new input on this topic:

You specifically mention a "T flash", does this mean that the function does
work with the F280, or does that flash also cancel these readings?

O.k., this makes some sense. Down to an electronics level that probably
simply means that there's an external memo signal, which will then always
trigger storing the readings in memory as soon as an exposure is made. Fair
enough.

Well, it's not so much the "not understanding" it, but rather the "assuming
it to be working differently" (which, one can argue, comes down to the same
:) ).

Unfortunately I only have a German 4Ti manual, and my German is not half as
good as my Dutch/English/Spanish, so at the time when I read it I probably
misinterpreted it...

:)
A nice camera for Fox Mulder... I'll check what's on page 116...
O.k., well this thread proved to be very useful, as I didn't realise the
memory function works the way it does. Now I do, so I can take that into
account...
Cheers!
