Even my 1939 90mm Angulon is coated.
- but my 1938 210mm Angulon is uncoated.
It doesn't always make that much difference!
This picture was shot with the uncoated 210mm Angulon, using absolutely maximum front rise as well as front and rear tilt to get even more rise, on 8x10". You can see that I managed to exceed the sharp coverage of even this lens, but keep in mind that everything in the picture is above the camera position. I tried "forcing" an image circle well in excess of 500mm, more like 650mm! The bellows is intruding in the bottom, too...
Is the Angulon design the same as the Dagor or the wide-angle Dagor? I've heard them called Dagor- and reverse-Dagor designs...
Keith ~ If you're going to be doing landscapes, you probably won't need a whole lot in the way of movements. The 210 Angulon might be expensive overkill. A 215mm f/4.8 Ilex Acuton (aka Caltar-S) is a lovely coated plasmat that covers 8x10 sharply to the corners with a little bit of movement, and converts to a 360mm, (even has a factory scale for the conversion on the shutter). They're often in the $150-$200 range for a nice one. There are quite a few other lenses that would work well on 8x10 in that focal range too...

BTW, with 382mm image-circle the Angulon 210mm at f/16 can be shiftet 60 resp. 49 mm.
But there is a much better lens with 500 mm image-circle: the Super-Angulon 210!

I bought a `new` Nikon 240mm f/5.6 Nikkor-W today. Mr Cad in Croyden, UK still have some of the final batches of the Nikon lenses in stock. I also bought a Sinar Norma 8x10 which also has a 4x5 reducing back and two 8x10 DDS`s. So I should receive my first 8x10 Camera by Tuesday.
The Nikkor-W is a fine lens, and multi coated too with an image-circle of 336m at f/22 it fills 8x10 but only not much more. So a nice Angulon 210mm, or Super-Angulon, could be your next lens in the short direction.
Much success with your LF-camera!
A "Dagor" is a lens where each cell has three cemented elements in the order +-+. "Reversed Dagor" is used to designate a lens where the elements are in the -+- order. One example of this is the Zeiss Doppel-Amatar, another is the Angulon. The Angulon, as Peter writes, has an enlarged front element to avoid vignetting.
Schneiders stated image circles are very conservative, as my example above shows. That was shot with almost 250mm vertical shift - way more than 49mm! Admittedly it goes soft in the top, but 200mm vertical shift in portrait orientation should still give enough sharpness for contact prints.BTW, with 382mm image-circle the Angulon 210mm at f/16 can be shiftet 60 resp. 49 mm.
Also: The construction of the Angulons was changed several times, and earlier examples have a less abrupt drop in sharpness when the stated image circle is exceeded. Many will find these quite acceptable for much larger image circles than Schneider states for the newer lenses. The original specification for the very first 210mm Angulons was 500mm image circle - but that is overly optimistic...
