Yikes. I love to come back to these threads from a couple of years ago and revisit the idea to see what has changed. Sadly I am not carrying Kodachrome anymore. I am not really shooting all that much slide film either.
Here is the inventory in the bag: 21mm f2 Zuiko, 24mm f2 Zuiko, 35mm f2 Zuiko, 85mm f2 Zuiko, 100mm f2 Zuiko. Kodak Ektachrome E100VS, Kodak T-Max 400. Filters, cable release, spare silver oxide batteries.
I generally carry my old beater tripod and I have the OM-4T with either a 50mm f2 macro or a 50mm f1.4 mounted and I leave the camera body on the car seat beside me.
