I bought a 0.42x converter at a camera fair. It didn’t have the right adapter for my fuji so I just held it in front of the lens. It and the bus window were pretty cruddy, so after defishing the shot with panotools I thought I’d add to the low quality look and ran a lomo action on it. The lomo action blew out too much detail for my liking so I backed up a bit in the history. I’m fairly sure the action came from here, but I can’t connect to the site to check at the moment.
The converter is destined to sit on an old 6x9cm folder and is part of the ongoing investigation into finding cheap ways to do medium format panoramas.
