Hi,
Thanks for your insight. May be, the reflections
originate from the inner part of the lens housing ?
(if the painture of inner side is not all matte).
I agree, that these lenses are difficult to use;
therefore,I decided in favour of the SMC-F fish-eye
zoom (zooming may allow adjustments of the degree of
line distorsion - this probably make the usage of the
lens less difficult).
However, I am still intrigued by the idea of a
circular image with an angle of 180 degree view in all
directions.

I have a Peleng, the lens is sharp but suffers a lot
from internal
reflections which are giving light rings on the
outside of the picture
circle. Its not flare but something different. The
picture circle is a bit
larger then the short side of a negative or slide
(about 25 mm). The lens is
cheap in it's kind, well build, painted instead of
anodized and mine came
with a Nikon adapter. When using it with a Nikon
adapter you can't use it on
a F-camera like the F, F2, F3 etc because there to
little space for the
cameramirror behind the lens (reason: backmounted
filters which you have to
use and are included) a Nikon FE didn't have the
problem. I didnt't have
problems using it on a MZ5n or a KX/MX but maybe the
LX will be problematic.
These kind of lenses are extremely difficult to use
and a IMO a bit of a
gimmick
Don't know about the Sigma, its a lot more expensive.
