I am still exploring how I want to photograph on the streets of Hanover, PA. I had thought that I would be able to use a fixed 23mm lens on an APS sensor camera, but I have changed my mind. I will need a zoom lens if I wish to correct for distortion, etc. and get both close-ups and wide shots of how it looks. I am now considering different cameras and lenses … maybe a zoom lens that starts around 16mm.
