    Default Question on shot taken..

    Hi,

    Need to seek help from experts out there for the shot I took recently.
    Looking at the thumbnail from afar, there is a halo ring on the shot itself. Not sure if this is the so call lens flare?

    I had a UV filter attached to my 18-200mm. The shot was taken at 200mm.



    Thanks for any replies.

    Cheers!

    i dun think its call a lens flare.. most likely is vignetting effect due to the lens or filter..

    Vignetting at 200mm? Not sure how likely that is. Try taking 2 shots of the same thing with and without filter, then see if there is a problem.

    It's not due to any filter. I also have this same issue with my 70-300 at 300mm end when i took the NDP aerial displays and it's mainly due to light fall-off at the corners. At lower lighting conditions, this effect is pretty common i would say.

    looks like lens flare rather than vignetting because the cranes are still very visible at the corners

    Looks like an interference pattern to me.

    What is the best way to take a shot at such conditions? Any advise?
    Thanks.

    It's due to lens construction, if i'm right. Pics taken like this can only be corrected after doing some post-processing.

    Real freaky man, a white ring around the helicopters. Did you take a photo through a glass window?

    I'm no expert too, but there's a huge difference between flaring and vignetting. Go figure out.

    Hi,

    See section under vignetting @ 18-200mm
    http://www.imaging-resource.com/PRODS/E50D/E50DA.HTM

    This is exactly what I have been experiencing although peripheral illumination correction has been enabled.

    Any advise from experts out there?

    Thanks in advance.

    Cheers!
