Hexar AF viginetting

[agricola]

Hi - have been lurking for quite some time.
I've acquired a Hexar AF - the Silver version with the databack and 35mm f2.0
I took some shots in poor light and program mode. The scans which came back from the Kodak shop who developed the roll showed what looked like pronounced viginetting at the corners.
Is this a known quirk of the Hexar AF lens when operating near max. aperture in poor light?
Other shots taken in good daylight conditions were clear and sharp edge to edge.
many thanks

are you using a filter by any chance?

There is probably some, but not very noticeable to me. What might be happening, is if your images wide open are very light (sky, light walls, snow, etc.), then the auto-contrast program of your lab may be darkening the corners.

Thanks. No. Filter not used. Only thing that could have caused it from the outside was the lens hood which was pulled full forward as the lens cap was removed.

I think I have just found out how to imbed images in messages. Here goes -
1. Indoors in shopping mall, from the first roll through the Hexar AF, as developed and scanned by Kodak shop (they were all near perfectly developed and scanned).
2 & 3 are from the second roll via the same Kodak shop - and contrary to what I said earlier they were taken in broad daylight - I had forgotten about them, the ones I remembered from the second roll were evening shots but these at the beach in bright sunlight are 'glaring' examples of what I am talking about - you can see what has happened at the corners.

@agricola - this is surprising. i have heard of the tendency of the hexar af lens to vignette wide open but that is definitely not the case with your attached shots. looks like ampguy is on the right track.

i find the slight vignetting desirable but the last shot is something else!

 

[agricola]

thanks infrequent - yeah ampguy must be right - the first roll was spot on - will just have to get off my backside and run a few more rolls through it - the first lot were spectacular, but none of them were in high contrast situations at the beach

also may be try different labs just to make sure?

 

[agricola]

true - or do it myself - apart from being lazy I gave all my darkroom/developing gear away a couple of years ago - then this happens!!

some scanned b&w

here are some bw photos I developed and scanned myself - there is some vignetting, but on your 3rd photo it looks like the vignetting may have come from auto-contrast. With some labs and drugstores, you can ask them to turn it off or process "as shot"
