The only exception I know is the Nikkor K / Ai 4,5/300mm ED (non-IF!). It's corrected from 400nm to 1000nm, and it's color aberrations have been reduced to 10% (compared to the non-ED Nikkors).


Well, unfortunately I have a Nikon allergy; i.e. it's unacceptable for me that these lenses operate in the (for me) wrong direction. I've already given away all my Nikkors for that reason. Wink

I've no problems with the "wrong direction" (even though I'm coming from the "right" side as well: Mamiya / Minolta / Sony) - but most of my Nikkors in some way have focusing problems such as stiff focusing, dry focusing, or even completely blocked focusing (AiS 2.8/105mm Micro). Those which haven't (e. g. the AiS 1.8/105mm and some of the 2.8/55mm Micro which both have a very smooth focusing) do have stuck apertures!! To me it seems that Nikon didn't use the same quality of lubricants that were used in Minolta MC-II / MC-X or Leica lenses.

So can someone show samples of the image from this lens ? Your thoughts compared to other old 300mm ? We sell one sample for about $ 150 Is it worth it?

You want to see images of the lens or taken with the lens?

Anyway, here are pictures of the lens, taken quick and dirty with my smartphone:

Anyone compared this lens to Nikon ED IF? Is Nikon better or not? Thanks

At infinity, the Nikkor AiS 4.5/300mm IF-ED has much less lateral CAs than the Minolta MD-II 4.5/300mm IF. Corner resolution wide open is comparable, though the Nikkor may have an edge.

The Minolta has a a more sophisticated IF system than the Nikkor (two elements moving independently for better close range correction, compared to the Nikkor with only one element moving). I haven't tested the lenses at close range so I can't comment on whether the difference actually is visible.

At least in the German "MinoltaForum" the Minolta MF 300mm lenses always had a mixed reputation. The MD-II 4.5/300mm is surprisingly lightweight (as is the Nikkor AiS 4.5/300mm IF-ED), and focusing is a joy. Central sharpness is very good, but it's not a "landscape lens". It's more of a sport/animal lens, and as such I can recommend it. If you can correct its lateral CAs during PP, you may also use it as a landscape lens.

Minolta was saying at the time that the 4.5/300 was using "new" glass. Most certainly was NOT using ULD/ED glass (V=80), but only LD glass (v=70).

Only a few years later, when releasing the Minolta AF 2.8/300mm APO, Minolta had their first "AD" (anomalous dispersion) glass incorporated into a lens (the Minolta proprietary "AD" glass was similar - but not identical - to the Schott / Nikon "ED" glass). That lens was as good as Nikons 2.8/300, finally. Also the later MinAF 4/300mm as well as the (even better) 2.8/300mm APO G SSM were excellent.
