Thread: What filters

  1. #1

    What filters

    I have a Nikon dslr 3100, I am am a newbie so bear with me. I have a 18-55 and a 70-300 which I have used with success but have just bought a used Sigma 4-5.6 10-20mm wide angle zoom, there are no filters with it. I think I need a UV filter which will also protect the lens but I believe there is a filter that will enhance blues and greens outside.

    You don’t need a UV filter – putting an extra bit of cheap glass in front of a lens isn’t going to do anything positive for image quality and unless you’re in extreme conditions it doesn’t need protecting
    The other one you refer to is a polarising filter

    UV filters were used back in the film days, but with digital sensors their usefulness is mostly just relegated to protecting the glass on the lens.

    Polarising filters also have the benefit of cutting out reflections, so it’s a good addition to a kit.

    I highly suggest a polarising filter and an ND filter.
    I have a polarising filter for both my Canon 24-105 and 50mm and leave it on all the time. It protects the lens and is much cheaper to replace if it gets damaged.
