Built this demon with some junk layin around. The only expense was the set of bag bellows I had to pillage from my 4x5 setup. I've only used them once so they were automatically volunteered for the task.
The setup basically allows me to use my 4x5 lenses with my Pentax 6x7. The SLR functionality makes this a perfect setup chasing storms which if anyone living in Brisbane knows are a huge part of landscape photography in summer.
The top of the Pentax can be removed to reveal a ground glass which makes me feel right at home.
