I am not a 'professional' photographer, meaning I don't make my living from
photography, but I have done so in the past. I am something of an 'expert'
by virtue of 45 years of experience, study and teaching. BTW I plan to do a
photography workshop at the gathering if anyone is interested.
Many 'pros' are resistant to digital and other advances in photography. You
can often spot them by their attachment to old mechanical cameras. I am in
the middle. I still love the old equipment but also recognize what the new
stuff will do that the old couldn't.

There are digital cameras that produce can photos which blow away the old
mechanical camera's results. A Canon 1Ds, for example, can produce a higher
resolution photo than ISO 100 slide film. Its problem is that it is very
expensive (lists at $9K for the body only) and it's heavy. A friend who
owns one (he's richer than I) tells me that with his favorite lens, a
24-70mm, it tops 4.6#. Not exactly a hikers camera. If you are willing to
tote even more weight and have an unlimited budget I can point you to some
medium or large format digital equipment that has even better resolution.
The point here, however, is that *if you want the highest image quality for
your dollar* film still beats digital.
FWIW - I suspect that re-scanning the film from your disposable could give
you better files. I say that because you said the prints were better.
Although the cheap plastic lenses in disposables don't make for high
quality negatives, most consumer photo processors doing photo CDs from film
scan at very low resolution thus compounding the problem. You need to find
someone to scan your original film at a minimum of 2700 dpi. I'm not saying
it will be great but they should at least match the quality of your 4X6
prints and may well be better.

I have to question your pros explanation of diameter of the lens because it
is not measured in mm. The diameter of the glass (or plastic on cheap
lenses) is indicated by the maximum f/stop. Digital cameras use shorter
focal lengths (the mm part) because the CCD or CMOS that records the light
has a smaller area than standard 35mm film. The same is true for APS. The
Canon 1Ds is an exception. The CCD on a 1Ds is the same size as 35mm film.
The light gathering power of the lens is the ratio of the diameter to the
focal length thus you can have a small diameter lens the same focal length
as a large diameter lens of that focal length (i.e. 50mm f/8 VS 50mm f1.8).
Neither set of numbers indicates the quality of the lens.

The Canon AE-1 is a good camera but as you observe, it is heavy. And
although the lenses are very good, so are newer lighter lenses. I would
recommend that you carry an SLR on LD hikes *only* if you intend to take
advantage of the other capabilities of an SLR meaning, multiple lenses,
filters, extension tubes, etc. If you are going to use the camera as a
point and shoot, buy a quality point and shoot camera. They are smaller,
weigh less and generally less bulky.
I'm still in the process of making up my handouts for the Gathering Grey
Owl, but I'll forward a copy of the equipment recommendation handout
separately since the list doesn't accept attachments. I invite everyone to
come to the workshop.
