Never had one until a year ago. I bought wood Burke and James 5x7 on Ebay for $150. It's an amazing camera. I put it in my old RZ bag with one lens and 2 film holders and it weights about 6 pounds. It doesn't have the precise scales and movements like my Sinar 4x5, but its a perfect field camera. I make my own lens boards too. I"m going to take it to Yosemite this winter.
