Most of them are crap, so my use of the example was purely theoretical. I have limited personal experience with WA convs. Any Conv is a major PIA in general. Period. Some are OK for specialized shoots, but for normal photography while in the field or travelling. Bah!! I have used both of the WA ones Nikon make ffor there 9xx series, and the most expensive one is decent, but it still of course magnifies the distortion of the native lens and exacerbates the CA.
I have used Sony WA adaptors, and in general they have been mediocre quality, but knowing Sony, and given the lens design of the 707, I have to believe that they will soon have a convertor ready to sell you--and I suspect it may be of better quality than in the past, but the price will also be better--knowing Sony (I have had lots of Sony stuff in my day).
In the end you are probably right that it is very hard to meet my theoretical standard of a WA that won't degrade the image some at least.
If anyone has a good one out there it is probably Oly--and there might be one that will work on that 58 mm Sony, but it will not have been designed to optimize the optical connection to the native lens, so it would be a miracle if it wan't problematical.

I've been questioning whether it's even possible to put a converter
on the front of a very good lens without degrading the quality.
What I've experienced so far says "no", but certainly haven't tried
them all. Ergonomics and added cost aside, it's hard to imagine
that there wouldn't be a significant loss in optical quality with
any converter. What's been your experience?
Anyone else had positive results using wide-angle converters with
their digicams?

But I would choose the D7 over the Sony for the differtial cost of
a WA convertor that did not degrade the Sony glass and had at least
as good optical quality as the D7--and I still have until next
Monday to return it, so it is not posturing on my part. I don't
know quite what dollar value to put on the pure PIA of having to
contend with a convertor for WA, but I suppose that should be added
to the differential as well.
