I shoot landscapes and seascapes with long exposures up to 400 mm and even 560 mm with FF. What Medium Format lenses longer than 300 mm would you recommend? Does any of them have a leaf shutter so it can be used with the X1D?
What camera system are you using or planning to use? Though it is a 35mm lens, I know that the old Leica 560mm f6.8 Telyt was supposed to cover the Pentax 6 X 7 film cameras. I know that the mount or the rear tube needed to do this. If you want I can check with my friend Jim Lager, the author of 8 Leica Books and ask if he remembers what needed to be done with the lens. Of course this lens would need a focal plane shutter since it has no leaf shutter. Also, it takes some practice to use for focus, but for Landscape work it should be doable. The biggest issue is the field curvature so that the edges would not be as sharp as the center. But, the lens is a follow focus design and quite light.

Thanks, I have no immediate plans, just checking for possibilities. I am afraid the old Telyt lenses (not APO-Telyt) just won\'t cut it regarding optical quality and especially CA. Aren\'t they also very long physically? something I try to avoid, as it is disastrous to long exposures with the slightest wind.
Yes the old Telyt lenses are quite long. I am not sure regarding CA they are quite sharp in the center. I and Doug Herr (telyt) have switched over to the Canon new 500mm f4.5L FD lens for our Sony A7 series cameras because of the ease of operation and performance. I have no idea if they will cover larger than FF 35mm. But, back to the Leica Telyt, I totally rebalanced mine for work on a tripod and as I remember it is about 4 pounds and balances exceeedingly well on the tripod since I designed and had a bracket made to rebalance the whole assembly.
