While in Seoul, I went to the main camera shop area of the city, and had a look for lenses that would be of interest. I found a few examples of the EF 180L macro around at various ages and prices, and also had a look at the tamron 180 f/3.5 macro, which although it was very sharp, the focussing motor was pretty loud on it. The price was a little more than the second hand 180L I bought in the end. This was my first real shoot using it as a macro lens:
