I went down with the SPB to the camera market in Ultimo. It mostly has old stuff. I was unable to find what I was looking for. I wanted some extension tubes and a light meter, and some ND filters. The problem for the extension tubes was that my mount on the camera is too new and they only had the old canon mounts. Talsit suggested a bellows, which was something I had never thought of. But no luck there either. For the light meters, I only found two and neither worked. And with the filters, well my lenses need very big filters, but older cameras all used very small ones. So it is hard to find any in the second hand market. Afterwards we went to super bowl for lunch.
