40mm Nokton vs 35mm Nokton F1.4

Ok I just learned that "edge fall off" also refers to vignetting. Is that caused by not using a filter/hood? It seems that when shooting wide open causes vignetting. Why is that so?

Interesting that you get this corner vignetting. I haven't found any on either of my 40's. Doesn't bother me, but I will now look for it on mine!

Tom, I had that several times with my Noktons. Don't really understand when it happens / cann't reproduce it. For example:

Note that digital post-processing makes it typically worse of course (contrast enhancements, S-curves, etc.).

Best,

Roland.

I'm not bothered by the vignetting in my shots so far... in fact I've not noticed it at all until you highlighted it, Tom. On the other hand I quite like the effect of it, I guess its a personal taste.

But theres one issue I would like to clarify, thought I might be a lil off topic; Does vignetting occur on all lenses inherently?

Roland, there is something wrong with your lens. I'll be happy to take it off your hands, tho. 🙂

PS>Thanks a bunch for the spool.

What is interesting is that the 35f1.4 and the 40f1,4 are pretty close in their design and I haven't seen the vignetting on the 35. It is pretty normal to have it, particularly on a fast lens like the f1,4's - but then it usually only shows up at wide-open. Rolands 2nd shot looks stopped down a bit and it is still there. It could also be in post processing of course.
If the damned rain stops here I might break down and find a white wall to shoot and see if I can duplicated the effect.

Light fall-off is quite apparent in these shots from my Nokton 40 S.C. (probably shot at f/2). I don't have anything handy from my Nokton 35mm f/1.4 S.C. to compare.
