I've been having fun with a couple of Minolta Dynax cameras. These were very expensive beasts in the 1990s and 2000s but are now available for around £20 including a lens on the secondhand market. No duds yet. They seem pretty reliable.
Anyway I've been taking some Agent Shadow pictures with a one f-stop boost to get round the dull autumn light in Scotland and the results are on my Lomography site.
And here are a few pics to get you started.
