Is 35mm worth the effort?

[Lem0nade]

I have a 35mm Canon Eos with good macro lenses, and was wondering whether learning to shoot with it would be worth the effort.
I was thinking it may be obsolete, with digitals around now that take such great shots. I am looking for good shots of a fish tank, so I need one that can deal with glare and water.
So should I bother learning to use my 35mm or just buy a new decent digital?

Camera's don't take care of glare and reflections
You would use a polarizer filter to help with that.

Are fish tanks the only thing you will be photographing? Do you mean hobby type fish tanks one would have at home or Huge Aquarium type fish tanks you would see sharks and large fish on display ?

The one thing that digital affords you, is you can keep take the picture over if you notice too much glare in the picture.
With film, you won't know that until you already pay for developing
