Novoflex
... novoflex's 0.2um number sounds great to me, but I'd expect that to be rather optimistic (ie marketing) numbers. should work up to very high magnifications. also, novoflex does provide the thing as a fully featured integrated system, so it should be useable straight of the box. that also means t...

Big Update! ....None of the results were anything special until the last one, the Schneider Makro Symmar 5.6/120 and results are fantastic. Rodagon WA 4/40 + Schneider 5.6/120 Makro Symmar, at 3X and 100% view... The image is better all around on the MS120. The field is flatter and the corner sharp...

Others mentioned the improvement wasn't exactly striking but for me the difference was more than I expected and I was really glad to see that the SK lens didn't introduce any CAs. ....

Christian, maybe we are miscommunicating. (...) The specs clearly say that the lens is NOT apo corrected over the whole visible spectrum. It is corrected for 480nm-1800nm. In contrast, the wavelength range of the normal 10x apo is 435nm-655nm. .... I don't know how bad they will be, but there must ...

No, for the reasons I just gave. The specs clearly say it is not corrected for blue light. Lou, perhaps I said it not clear enough: I'm, for myself, not interested in the near UV correction / blue light at all and did not point to the correction of the blue light. I just wanted to explain, that the...

... Yes, the spectral range is bigger than that of the ordinary Mitutoyo lenses, but the range is also shifted toward the IR end of the spectrum. Lou, if I try to read it critical AND if the wording in the Mitu description is not just plain / fooling advertising -- for "our" normal use of light in ...
