That is how I checked it: wide open - and it is
the best so far on the VX-2000 at the widest zoom
setting and widest stop for far corner performance
(a subtle bit better than the excellent WD-58 Canon),
and noticeably better for distortion. Its failing:
you cannot zoom through the entire range without
getting first flarey corners, then overall poor
performance toward the tele end. Darn! ;-)
I would expect it to perform similarly at the short
end stopped down, unless the optics are decentered.
I have not tried it at the long end stopped down
in bright light - it may be acceptable then...

Yes - it is ideal for this - except that it is not
very wide... (I prefer fisheyes for showing interiors,
since they show MUCH more, but keep size relationships
between parts of the scene more "normal" than with
rectangular-perspective wide lenses.

No - it comes with a native 58mm thread, metal,
as I recall. Most of the barrel is short and
light plastic, with a metal rear section.
It is MUCH lighter than the Canon, and shorter.

The 6600 would not be easy to remount fast, but could
be removed quickly. BTW, the much wider Sony ES06
screws in, but then has a quick-release for
mounting/unmounting. And the curvature is much kinder
to people shapes, and keeps people from looking fat
at the picture edges. I prefer having barrel distortion
when shooting people with wide-angles...

I have not tried filters yet to see how much clearance
there is on specific cameras...

>the now rounded corners.
Yes - it is generally slight, except with some fisheyes.

>around light sources.
"Ghosts" are a string of diaphragm images running out from
the light source.
>Barrel distortion is - how the pic bends all around the outside edges, seen
>as curves in straight items the further from center they get.
Yes. And "pincushion" distortion is the reverse. In some
lenses you can find "wavey-line" distortion which is
an unhappy combination of barrel and pincushion (a happy
combination would at least partially cancel the predominant
distortion type).
>Pass Through Distortion is- If your lenses are wacked to begin with, adding

>normal wide distortions.
The converter is unlikely to correct lens distortions;
if there is barrel (or the worse pincushion) in the lens
a no-distortion converter is added to, it is likely
those distortions will still show.
>Flare is - light bouncing off of all glass, seen as concentric circles or
>star shapes blowing through the lense off of light sources
This is more closely related to "ghosts", but is in the
fuzzy area between these two closely-related faults.
"Flare" is a diffuse illumination in the image that spoils
dark tones (especially black), and can often originate even
from very light-toned areas in the image (a fogged filter,
many scratches on the lens, or much internal fungus would
do this).
>Zoom Through is - the ability for the camera to maintain focus while zooming
>even with the addition of the lens, seen as you can still focus when zoomed
>up.
Yes - and one hopes lens sharpness will also be maintained,
but this is rarely true with fisheye attachments and, it appears,
it is also not true with the 6600, darn...
>Stepping Rings - adapters to go from one thread size to another
Yes. Rarely can you step down without vignetting, but the
52mm-threaded Sony ES06 will mount on the 58mm-threaded
VX-2000 with a step-down ring without vignetting. Many
simple and achromatic close-up lenses can also be used
with step-down rings without problems.
>.3 .5 .7X - are how much wider the pic is reletive to the original lens
It is the magnification factor for the lens FL when the
converter is mounted on the lens, at any FL the zoom is
set at; the converter also shortens the lens FL at its
longest FL setting. If the converter cannot be used through
the whole zoom range, it seriously limits the availability
of long FLs when mounted by shortening the lens at
any particular zoom setting, and also by restricting the
range of available zoom settings... (But, some of us are
WA nuts, anyway, so.....;-)
