    Default Vignetting - now you see it, now you don't??

    Hi All,

    I used my Circular Poralizer to take the following 2 photos, seems that the second pic has vignetting. Just wonder why?

    I have an adapter tube, with a 62/58 step down ring...

    No vignetting, so happy.


    Vignetting occured in this photo


    Can someone help please??

    What lens were you using? What is your focal range (zoom lens I presume)?

    can I confirm that u r using 58mm CP? If yes then definitely u get vignetting when u r not zooming. CP also thicker than UV filter. if u do filter stacking then u cannot runaway from vignetting

    that sounds weird cause I dont find any vignetting with my 62mm CP. Actually FZ20 itself has a slight vignetting.

    Thanks a lot for sharing. Now that I recall the second photo is with CP stack on top of star-8 filter.

    Don't ask me why, but just for the fun of it to see if there is any effect...
