Prehistoric

Avebury Stone Circle, early October. Canon EOS 30D and EF 35-135mm f/4 - 5.6 USM lens set at 85mm (field of view equivalent to 135mm on a full frame camera). 200 ISO; f/11; 1/500th.
This lens was in production from 1990 - 2000. It's not bad on a crop sensor camera like the 30D and that's allowing for the parlous condition it was in when I bought it from a short-sighted person with very limited powers of description who was a seller on eBay. I had never seen a lens so dirty and neglected; the dirt concealed some scratches on the front element. But as I have remarked before, scratches to the front seldom make a ha'porth of difference, and the dirt didn't prevent a smooth operation of the zoom and auto focus. Not bad for £37.
