My marriage of an Aero-Ektar on a Speed Graphic started off rather rocky, but now that I have made a dozen or so images I am starting to appreciate what this combination can do (so I'm no longer trying to sell it!). So it's a keeper, at least for now. Which gets me wondering - I really like using my Technika IV much more than a Speed Graphic. The Tech's RF is in the right place, it is more solid, and it has usable movements. However, it does not have a focal plane shutter. Has anyone ever used one of those rare Linhof focal plane shutter attachments? I see them on eBay a couple of times a year, and suddenly they are looking attractive. The other lens that looks neat is the 150/2.8 Xenotar in a shutter, because it could be cammed and used as-is. Any caveats? That really looks like a great lens - also very rare.
