The lengthy review I read on the AF2 that discusses the vignetting stated it was caused by the in-camera processing. It didn't go into detail.

What review was that ?

Can you provide a link ?

Vignetting is caused by the lens , not the film processing , typical of wide angle lenses built to a lower budget .

I suspect ya'll's understanding is a bit limited; as was mine. It's a little more complete now due to this Interesting article. The link I looked at was called the Casual Photophile. Here's a different link that describes vignetting in more technical terms. The types of vignetting that might be affecting these pics is described in The paragraphs under Optical and Natural vignetting and would especially affect Rangefinder type cameras.Vignetting - Wikipedia

There's nothing in that article that I didn't already know .

Nor is it a review of the camera in question that you referred too , which is what I asked for  .

I've been shooting film a long time , and still do , from sub miniature formats to 8x10 large format film .

Vignetting can affect all formats but are always down to the same reasons .

A badly designed lens or mechanical blockage in the light path .

Vignetting with wide angle lenses on range finder cameras is still an issue with the lens design that's harder to correct than SLR lenses .

Large format lenses can also suffer from this where the solution is an expensive centre spot ND filter .

That's basically a screw on graduated ND filter that radiates out from the centre of the lens to darken the centre of the image as much as the outer to give even illumination .

I have one for my 90mm Super Angulon for when I'm using 5x7 film .

Same lens used on 5x4 doesn't need the centre filter as any vignetting is well out of the frame .

IIRC these filters are also available for some rangefinder lenses to correct this flaw .

.

As already pointed out , there is no in camera processing with your camera .

The film is exposed , depending on the aperture the camera selects , vignetting occurs at the larger aperture's .

The film is removed from the camera and then processed .

The end result is as seen .

Unless someone sprinkled pixie dust on your camera , no processing takes place in camera .

I have quite a few point and shoot cameras as well . Most exhibit this flaw .
