I have had a Nikon D3100 with a Tamron 18-270mm lens for about 5 years now and I take thousands of shots a year, but I’m ashamed to say that I’m stuck in auto!
My defense, and it probably isn’t a very good one, is that I take hundreds of 5k Parkrun photographs most weeks, in sunny old England, and I just don’t have time to mess about with my camera because the runners are going past very quickly. There are about 300 runners a week, and I like to get at least one shot of everyone. With that said, I put it in “Sports mode” while this isn’t so much of a problem in the summer (which incidentally is about two weeks here), but in the winter months with cloud and rain, my pictures aren’t so good.
My question is, would I be better off learning more about my D3100, that is coming out of auto, or upgrading to a camera with a better sports mode?
