Can anyone who understands MTF charts help me with this?
I've had a bit of a mental block with MTF data and I've only just realised that I,
too, can understand and utilize MTF charts. I found an explanation here:
www.canoneos.com
in the Glossary that made sense. Here is what it says about the a
Why not lock the exposure value before taking your eye away from the
finder?

Has anyone tried this tripod with their EOS gear. I use a Elan7e and my
heaviest lens is a 70 - 200 f4.0 and am looking for a lightweight tripod
to use while hiking. This one got a pretty good write up in pop photo
but that could just mean that Velbon is a big advertiser with them. I

This is the problem. Once the metering values generated by the camera were
affected by the viewfinder light leakage, the final exposure would be
improper.
If say, metering through the lens produced 1/125 @ f/8 with blocked finder,
uncovering the eyepiece would produce, say, 1/200 @f/8 (we are worki
totally agreed. Nothing is more convincing then practical thing.
Perhaps I'll do it in some foreseen future.
However, the question of camera metering being affected by the excessive
light through the finder is still open. Any takers ?

I'm sorry, I thought we were talking about using extarnal (manual) metering,
i.e., B setting. Yes, light entering the viewfinder COULD affect metering by
the camera, but that same light WON'T reach the film/sensor surface.

Of course.
But even though you entered proper exposure for the scene photographed, the
actual amount of light will be increased due to stray lighting passed
through the finder. That may lead to overexposed frame to certain extent,
even though the exposure value where correct for the light amount th

You were asking about a B exposure, presumably of several seconds. The metering cannot

This is exactly what I meant. The metering will be affected causing the
improper exposure calculated by the camera.

Good point Mike, perhaps it would indeed block the leakage, however I doubt
it would help for camera metered exposure. The metering is done prior to
mirror going up and is fixed already when the mirror is going up leading to
the actual exposure value used just prior to mirror flaps up - will still
Any stray light entering the viewfinder could only affect the metering, not
the actual film/sensor. If you're trying to prevent stray light from
appearing on your image, there's no need to.

Joe I'm not sure I got your point, but I claim that the film exposure might
be affected from stray light entering the camera through the uncovered
finder in any case, would it be the camera metering or external one.
Suppose you are shooting during daylight (implying short exposure). Looking

Thanks guys, however, the case I was referring to isn't quite suitable for
the solutions offered (except probably of taping as offered by Peter).
Blocking manually by holding say a cap, black sheet of paper or something
like that would be fine
for relatively short Bulb exposures, however speaking a

There are several manuals for the D60 - hardware and software (Mac and
Windows). See the list and URLs at eosdoc:
