BTW: why some people diss the Angulon
I have been using Angulons for years and found them fully satisfactory, but online discussions always come up with people saying how bad they really are. This I discovered is an issue concerning how the individual lens was stored...
If you look at the old Schneider logo, with "Schneider Optik Kreuznach" in the diagram of a lens group, that lens group is half of an Angulon. since the inner surfaces of the two opposing halves have to be held really close to each other, each cemented group could only be held in the cell by the edge of the large front-most element. In other words, each half has two elements with no visible support other than the optical cement.
With an Angulon stored with its optical axis horizontal (as in leaving it on a camera), over time, the cement will gradually slip, making the elements slip out of alignment; that opens up a pandora's box of optical faults, even if the amount of slippage is tiny. In other words, Angulons (and for that matter, all large-format lenses) should be stored with optical axes vertical.
When considering the purchase of an Angulon, I always take the cells out of the shutter for a good look. After the elements were cemented, the edge of the whole group was painted with black paint; slippage of the element will result in the paint flaking off around the cement joints. If the edging paint is in good order, then you are in for a good start.
