This is the real deal, not some triplet wannabe. This is quite small. Therefore the aperture is not a whopping f4 or something which of course makes a whopping giant of a lens that tips your camera over. This is 14" f9 It will fit on a Linhof board! I don't have a flange for it, sorry. Just make a nice tight hole and friction it in. This would just cover 8X10 I think even at infinity. Maybe the corners would be dark, not sure. But at portrait distances this is a dream lens for your 8X10 field kit because it's so small. It retains all of the lovely Petzvally bokeh, but probably won't swirl for you. Need $225 for this. You pay shipping please.
