x-post.....vignetting with S50....need advice

[Trevor Ash]

Okay. I'll have to admit that I wouldn't be especially happy with that amount of vignetting either. While I've seen that amount of vignetting before in supremely wide angle lenses (like the Sigma 14mm EX) I can't say that I'd call it "normal" for your camera.

Question: Did you perform ANY adjustment at all on those photos? I ask because any increase in contrast or saturation will amplify the amount of vignetting in a photo.

I've attached some photos I just took using my G3 pointed at the wall. First photo is widest angle at largest aperture. Next is widest angle at smallest aperture. Then it's longest angle at largest aperture. Finally it's longest angle at smallest aperture. I did no adjustments except chose "convert to grayscale". I highly recommend you take these photos of mine into your image editor and increase the contrast to see the vignetting even more.

I hope this helps. Personally, I wouldn't be too thrilled with your camera based on what I know and am seeing so far.
