I'm planning to finally jump into large format with a 5x7 Fotoman (when it's released). In the past I used a Pentax 67 primarily with a 45mm lens. What lens in 5x7 would be the equivalent?
Thanks!

105mm I guess. If you ignore the difference in format. 6x7 is a little squarer.
Simply using the ratios of the film diagonals, 88 mm and 209 mm, gives an equivalent of 105 mm.
But 5x7 is slightly more elongated than 6x7, so a slightly longer lens such as a 115 might be a better fit.
It also depends how much you want to spend and how light-weight you want the lens to be. Multicoated, faster, larger image circle will generally add to the cost.
A Schneider 110 Super Symmar XL is a good choice, light-weight, large image circle, multicoated. Can be found for a reasonable price used.
A 45m on the 6x7 is about 1/2 normal. Therefore, a 105 would be a rough equivilent. The only problem is that the proportions are not the same.
Go to
www.viewcamera.com
and then to the Free Articles section. There is a lens equivilent chart for getting as close as you can between formats. I would say anything from 105 ro 115 should work for you.
People will have different theories about matching - match the diagonal, the short dimension, the long dimension,etc., etc. When you change format proportions all you can do is get as close as possible.

Thanks for the info guys. Much appreciated.
