Help with my 15-85 new lens - DPChallenge Forums

Nikon AF-S DX NIKKOR 18-200mm f/3.5-5.6G ED VR II

I just got my 15-85 lens and mounted it on the Canon 550D better known in USA as T2i. I was trying to check if the camera had any sensor dust so I shot a blank white surface only to notice that the image had a darker vignette on the corners.
Is this normal for this lens?

In the end, you may need to download the new correction profile and install it in your camera (You need to use the canon software that came with your body)... That will at least help, - it's also possible that you do have the profile, but it's not activated for that lens..

" ... The Canon lens has a fairly large front lens diameter. Normally this should translate to well-controlled vignetting but the EF-S 15-85mm has significant problems at large aperture settings unfortunately. The worst spot is, as always, the wide-end with a rather extreme vignetting of ~1.9EV at f/3.5 (which is outside of our standard scale actually). This is easily visible in most field situations. The vignetting improves at f/5.6 but it takes f/8 till the problem is more or less resolved. Other focal lengths are not as affected but you should still reckon with about 1EV of vignetting here at max. aperture. ... "

That looks about normal.. Now, stop worrying about those slightly dark corners and go check out how well the IS works, and just how crisp and contrasty your photos are...

Is this designed to scare me!! You do have the same lens any problems there?

It always looks about the same at the wide end, no reason to be scared, go try shooting something besides a test image - you'll see why the lens rates as well as it does..

And make sure you have the correction profile installed.
