As noted in an earlier post I have a habit of running on trails with a camera. Generally I take a zoom lens. At first I used a kit zoom even though I own the upgrade, as I didn't want the speed anyway and certainly not the weight. I'd read a test that found that kit zooms (including mine) are about as good as the more expensive, faster zooms. However, I have switched to two better zooms because the kit zoom is too prone to ghosting (with the hood). This makes me a bit nervous. These are rough trails and while that means I jog not run I wonder if I ought to be using prime lenses. With my Nikon 35mm I can use primes but I simply refuse to spend the time scanning any more. Sorry to disagree with David Brooks on this point, but even if I value my time at a fairly small number I just can't justify the extra time it takes to scan rather than process a raw file. So I have limited prime choices, having bet on Olympus. (A 24mm Sigma is coming out in this mount and a 25mm Leica pancake is forthcoming; the 35mm Zuiko is a bit long for my purposes but I do use it sometimes.) So my long-winded question is, how much damage am I likely to be causing my zooms to be jogging with them?
When I finally get my website up - it's coming - I'll put in a post so people can see the results.
