Was in Washington DC last week with some school kids and used the kit lens and an Olympus 40-150 almost all the time. I also carried Sigma 19 and 30's but hardly used them. In the past I always carried several legacy lens and mostly used them. I didn't even carry them this time. I did notice on this trip that I have a spot or two on my G2 sensor. I see a spot on one of these pictures that I forget to remove. First and last pictures were taken with the kit lens and the middle one was with the Oly 40-150.
