While driving home from work yesterday, I saw an incredible cloud formation. It was one of the very high, whispy clouds well offset from the sun. There must have been a lot of ice crystals in it though because the sun, even it was a good 30-40 degrees away from the cloud, was shining through it like a prism. Unfortunately, by the time I got home to my camera, the effect was gone. This has happened to me several times. I often carry my camera with me and have caught some good pictures just by happenstance. There was a brush fire on a hillside, a bald eagle, some nice sunsets, etc. Over time, however, my main camera bag has grown from a small thing with 2 lenses, a few filters, lens cleaning materials, and some extra film into a backpack style bag with 2 bodies, 5 lenses, a mass of filters, reference material, etc. Some days, I am just not motivated to carry it with me to work so I leave it at home. So, what do you do? Obviously you don't carry your camera everywhere, but what do you carry on a regular basis and why? I have been thinking of buying another smaller camera bag (I donated my original bag to my kids for their equipment) but have been debating on what to carry in it (and what I carry will dictate the size I buy). I've been thinking of just my two zooms (28-80 and 70-300) with polarizing filters for each. I would take my 50mm instead of the shorter zoom but I need the macro capability of the short zoom until I get my 105mm micro.
