Ugh. Yes I did. So what? One example on a cheap zoom versus thousands
of good photographs with filters. And the person with the 28-105
didn't even post the results after removal of filter. So how am I to
compate? The link doesn't prove anything.
Even more, his filter might have been badly seated. I wouldn't be
surprised at bad results when the filter is not planparallel to the
lens/film. And a lot of filters can get loose under use/abuse.
Good light!
