    65mm Super- Angulon f/8 vignette solutions on 4x5

    Instead of trying to find a $400.00 center filter for the 65mm Super-Angulon, does anyone have a tried and true work flow to minimize the vignette issue with this lens in Photoshop? I have worked some on this, but it seems like it might be a combination of overexposure of the neg to compensate for the dark edges and a vignette controls in Photoshop. I would like to have anyone else's experience with this issue. Thanks!

    I couldn't find any $400 CFs, but look to Igor for some that are less than $200.

    Super Angulon 65/6.8? Ain't no such beast. Angulon 65/6.8, for 2x3 (6x9 in metric) that barely covers its intended format. Super Angulon 65/8, claimed coverage @f/22 @infinity 155 mm. Super Angulon 65/5.6, claimed coverage 170 mm.

    Which do you have?

    The list has a link to my article on center filters. Read it.

    I have a SA f8 that allows for a few mm rise, but covers fully (with some fall-off that doesn't bother me too much on chrome film), but an Angulon f6.8 cuts off the corners considerably... So no, does not completely cover...

    Mine ended up on a DIY panoramic camera made from a stereo 35mm camera with the area between the two windows milled out to about 3 5/8" wide opening, or like Dan sez; 6X9...

    Jimbo, with a 65 mm lens centered on 4x5 the corners will be ~ 2.5 stops down from the center. With decentering movements -- shift, rise, fall -- the difference will be greater. But with a 65/8 SA decentering movements will lose image quality ...

    If you're shooting reversal film, you'd best ante up for a center filter. If you're shooting negatives, film latitude should save you if you burn and dodge.

    Try things out.

    Wow!! I did not suspect a 2.5 stop difference in exposure from center to outside! I will be shooting B&W negs primarily. I'm not sure what Center Filter model number to look for. Igor has various Center Filters for the larger, 67mm. They are very $$. My lens has only a 49mm filter size. I imagine this filter is very rare indeed. My thinking now is to expose maybe 1.5 over normal and handle the rest in Photoshop. I have no darkroom and use a local lab that does a fine overall job. They are closed down now, but can hopefully open up soon. Thanks!
