Which center filter for SW-Nikkor 65/4?greenspun.com : LUSENET : Large format photography : One Thread
Unlike Schneider and rodenstock, Nikon does not market center filters for their LF lenses. Which center filter would be appropriate for the 65/4 SW lens? TIA, Åke

I owned the Nikkor 65mm for a couple of years and bought for it, recommanded by Robert White, the Schneider IIIC (2stops) center filter. It worked perfectly well. Now I replaced the 65 mm with the Rodenstock 55mm and the center filter still works nicely.

Heliopan, Rodenstock or Schneider

The faloff is severe with that lens. I use my Super-Angulon 47XL center filter on it with good results. (+ 2 stops)

Hoya also makes center filters, 2 stop, a lot cheaper. You can buy them from Adorama.

Ake, I'd go with the Heliopan 0.45ND center weighted filter, but to determine the strength you should run a couple of tests shooting a very large even toned and evenly lit surface, making sure the camera is focused at infinity, to see how much fall off there actually is. Do your tests with the lens centered and then shifted to the point where you see the edge of the image circle in two corners. My recommendation of the Heliopan 0.45ND center weighted filter is based on my experiences with that brand and strength when used on a Rodenstock Grandagon 90mm /4.5.
While the physics of why you may need a center filter are pretty fixed, I do know that Nikon uses a different optical formula from that used by Rodenstock & Schneider. Might this be an influence on what strength filter you need? perhaps, and that is why you should test. o rlisten to someone (not me!) who uses that lens either with or without a c.w.f.
