Hi,
thanks to Frank for the sneak preview of his review, which I look forward to. Star test results would indeed be very interesting - although it's probably going to be difficult to identify the culprit with the fixed EP. Since my TSN-3 body is a fluorite doublet at f5.5 too, but with 17mm more aperture and is very sharp and contrasty with no visible CA at 55x with the SDLv2, the 55mm doublet at the same focal ratio should be at least as good in theory...
From comparison of the Kowa small body zoom TE-9Z vs the SDLv2 in my TSN-3 body my main gripe was the lack of edge sharpness with the Kowa zoom at all magnifications while the SDLv2 is sharp to the edge for my eyes. On axis sharpness at 60x was ok iirc - but it's some time ago and no star test with it was made as this was at a very nice store that has since closed down after the death of the owner :-(
And yes, it really is the small body zoom TE-9Z - just look at the image of the sample in this link which still shows a zoom labeled 60x...
