So I have to make some tough choices, I'm only selling this lens to find a 150mm SS XL for my 8x10 shooting, essentially the same focal length, and sadly THIS lens is technically better, especially with weight and light falloff which is virtually non-existent on this thing from my experience. It's for 4x5 work, and an image circle of 195mm at f/16-f/22 according to Rodenstock. I've shot with this lens wide open on my 4x5 and not had any edge light falloff issues. Here's an example of an image I shot with this lens that shows you how the light even in the corners is pretty well even. Rodenstock wouldn't shoot themselves in the foot and they do say that for "critical motifs" work they suggest a center filter, but truly the light falloff is so marginal, I've never seen anyone who used one for this lens. It's a beautiful lens, but I'm not shooting as much 4x5 and something has to give. It comes with front and rear caps and the retaining ring, I'll include the toyo recessed lensboard if you want it, but will keep it if you don't shoot with a toyo as I have other uses for the board. Has the modern BLACK copal-0 shutter, not the older silver ones. "Sounds accurate" you won't need a CLA on this one it's practically brand new, strong and accurate shutter at all speeds. No dust or marks that could affect the image and frankly the glass looks perfect. I got this from an APUG forum member about a year ago and I'm selling it for the same price I got it for. No mold or must it anything like that has ever been near this thing, I kept it in my pelican case surrounded by desicant packets so it's been moisture free and out of the dust except when I was shooting with it of course. Here are some pics... More pics to come, see what Rodenstock says about it here... "The Grandagon-N with its wide field angle of up to 105° can really display its strengths in wide photos in close conditions, e.g. in architecture or industrial photos or in panoramic views. With the Grandagon-N, all the problems which occur in con- nection with large field angles have been ideally taken care of: The distortion has been reduced to a small residual value; the light fall-off at the edge has been greatly reduced thanks to an optical trick (“pupil distortion” = the entrance pupil diameter increases when viewing at an angle); the sharpness sets stan- dards for this class of lens. The Grandagon-N is available in two versions: With the maxi- mum aperture 4.5 in focal lengths 65 to 90 mm it has 8 ele- ments in 4 groups, and with the maximum aperture 6.8 in the focal length 90 mm it has 6 elements in 4 groups. The eight element lenses offer not only a high maximum aper- ture, but also a field angle of 105°, an even more uniform illu- mination and distortion values of less than 1%."
