My 28mm is an f2.8, my 50mm is an f1.8, my 90mm is an f2.5.
That being said, I'm thinking about buying an "all in one" zoom lens for my
"camera and one lens only" trips... But I'm wondering, when is a lens too
slow?
The ones I've been looking at which are compact and still give great range
(28-105mm) are like f3.5-f5.3 or something like that.
Is that really dark? Am I going to have to compensate (for hand held shots)
with faster film and thus get reduced fineness on the film side, or else
bring a tripod so I can use longer exposures and thus defeat the purpose of
using a zoom lens as far as carrying convience??
Thanks.

It depends on how you shoot and what your normal film speed is. I
tend to use ISO 50 film. On rainy days and heavy clouds I find I am
frequently shooting at 2.8 or 4. Remember that shooting wide open
which is what you will have to do a lot is not always the best idea.
One or two stops down from wide open usually gives you sharper and
better corrected images.
