Old brass lens in a SLR camera

<p>Hi, I got a old brass lens and I attached it to a Canon A1 SLR camera using a extension tube as an adapter. The maximum focus distance is around 40cm (16in).<br>

I took some pictures of objects at home and the results are interesting.<br>

You can see other pictures here<br>
