Hello,

My question is in the title.

With film, a center filter is good and reduces extra work at print stage.

With digital, hardware flter in front is not needed, as there are software solutions.

Which option is better or equal?

Thank you everybody.

Also, consider that the lens profiles that include vignetting correction expect a certain amount of vignetting. Some software (Adobe) even does not allow turning off built-in lens profiles. Vignetting also changes with the aperture.

As Jim wrote, with plenty of light, the noise increase due to vignetting is small. In low light, you would be adding noise to the center of the image, not removing noise from corners.

When you increase exposure to get the corners right, the center will be right there with them and the noise will be good overall for the first time.

It may not always be possible to increase exposure (shutter speed and DOF constraints).

I’d definitely want one if I was shooting chrome film in a Fuji 6x17, otherwise I never think about it.

Yes, for the film, it is certainly helpful. GX617 came with a center filter, AFAIK.

Yes indeed, But caveat emptor, many of those filters are long lost.
