I spotted an affordable Linhof Technika III I think it was, but maybe it's a model IV. Before I get too interested at the price it is at, I'm trying to figure out what the limits are on wide lenses and telephotos. I'm thinking my 90mm Super Angulon will work out on the Linhof due to rear movements possible so I'm not worried about wide angle. What's the longest lens that can be used on a Technika with a standard setup. Forgetting any rangefinder concerns, could a 600mm be used?
