I used to have a Canon non-digital SLR. I used a Canon-compatible Tamron zoom lens, can't remember the exact spec, 35 - 200? That's probably showing my ignorance! It was reasonably light and easy to carry, very versatile, and took excellent pictures of people, landscapes etc when I went travelling. It was also very reasonably priced. ETA: And I only needed to carry one lens so didn't need to keep changing over lenses.
