I've got exactly the same setup. The good thing about mine, is that I know my
pinhole is 0.1mm, and about 5 cm away from the film, making it f512. But I've
tried auto-exposure too, on slide, and it came out great on the first attempt.
Even better: when I turned the exposure compensation dial for an extra stop, it
came out over-exposed. That was 8 and 16 seconds resp.
Great little meter in the OM-4Ti :-)
Peter.
