I did the coolest thing this weekend...

I fashioned a little hood for the 4x5 and photographed my daughter's birthday party entirely with the 4x5 on a tripod by guessing at the focus on the screen (no loupe) and shooting some 79 and 54 polaroid. It was GREAT!

The only problem was shooting 80 speed film in shade with a 5.6 max lens. I had shutter speeds down to 1/8th.

SO...any recommendations for a cheap, fast lens that covers 4x5? Maybe something from the Speedgraphic era?
