I use this particular lens on my most challenging Nikon D2x, which shows any weaknesses of lenses used with it.
As a user of Nikon digital full format and APS-C format cameras I have to totally disagree: the D2x cannot show any lens weaknesses at all.
Mainly because of two reasons:
1. The 12 MP sensor simply does not have enough resolution to challenge lens performance. You get only about 75lp/mm resolution with it.
With films like TMX, Delta 100, PanF+, Velvia, Provia you get 60-100% higher resolution values.
And with microfilm based films like Adox CMS 20 II you will get up to 250 lp/mm. With that material you really see what a lens can deliver, but not with a 20 year old low resolution D2x.
On these old(er) 10-20 MP DSLRs almost all old lenses look quite good, simply because these sensors have very limited resolution (by Nyquist frequency) and do not really challenge the lens performance.
Put your old Nikkors on a recent D850, or better, use the above mentioned films. And then compare to the recent lens designs. Then you will see very big differences.
2. The D2x is a crop-sensor cam. So only the central part of the image circle of the lens is used. Therefore it is impossible to evaluate and judge the lens performance of the non-central parts of the image.
But with 35mm film we are using the non-central parts of the image circle, and they are important. Consequently a crop-sensor / APS-C digital cam is the wrong tool to test lenses for 35mm film.
The only real weakness I have detected with the vintage lense in question is a variable corner performance. It's center sharpness resolution is very high, while it's level of contrast is never found to be less than adequate.
You find the performance of the older lenses adequate for your personal photography. That is fine.
But that does not change the fact that
- the performance of newer lenses is significantly better
- other photographers have other needs and therefore benefit from the improvements in lens design.
I have done exactly that sir, and have found the multicoated Nikkor 50mm f2 to be the most accurate, refined and realistic rendering 50mm lens ever made.
Technical performance differences mean nothing to me compared to the above.
So again you are referring to your
subjective findings. It's o.k.
But other photographers go for objective differences. E.G. I prefer the much better three-dimensional impression ("3D-pop") I get with the Zeiss Milvus Makro-Planar 2/50 and Milvus Distagon 1.4/50 compared to the Nikkor 2/50, Nikkor 1.8/50 and 1.4/50.
I also prefer the better sharpness, higher resolution, better coatings and more pleasant color rendition of the Zeiss 2/50 and 1.4/50.
