Nikkor AF-S 300/4 and AF 300/4 same tests results?

By: contaxfan 5955 days ago
Hi everybody
My favorite lens on my Nikon F5 and D200 for wildlife is AF-S 300mm/4, it is sharp, light and affordable, so I was inrerested to see tests results for it. Unfortunately, it is not present on the old site, only older version Nikkor AF 300/4 was tested. I was suprised to find on a new photodo site, that Nikkor AF-S 300/4 showed the same identical tests results, as old Nikkor AF 300mm/4 on the old photodo site, when all other new lenses on the new photodo site were tested differently, showing just MTF graphs.
So, I wonder, are these test data just copied from the old Nikkor AF 300/4 version and new Nikkor AF-S 300mm/4 was never tested properly at all?
How to explain these completely identical data, if all new lenses were tested differently, and these two lenses have different optics and comletely different focusing distanse?

With all respect
Val, contaxfan

Hi Val,

I'm not sure what tests you are refering to, but I have never tested the Nikkor 300mm f/4 AF-S lens, only the AF-S 300mm f/2.8. I am a freelance and don't have anything to do with the other data on the site.

Merry Christmas,

Hi everybody,
I found another strange mistake in the specification information of Nikkor AF-S 300mm/4 lens on new photodo site, which claims that this lens has optical design of 8 elements in 6 groups, which is wrong.
Nikkor AF-S 300mm/4 optical design is 10 (ten) elements in 6 groups, closest focusing distance is 1.5m (1.45m presicely) or 5ft.
Old Nikkor AF 300mm/4 has indeed opical design of 8 (eight) elements in 6 groups and closest focusing distance of 2.5m or 8ft.
These are completely different lenses with different optical design and different focusing distance.
So, I still suspect, that MTF data for Nikkor AF-S 300mm/4 is actually MTF data of older version Nikkor AF 300mm/4, which was just copied from old photodo site.
It is sad, because I really wanted to know all true specification of my favorite Nikkor AF-S 300mm/4.
I must add, that lenses specification data on old photodo site is much more informative and precise, than new lens specifications by new methods, and I am very gratufull for opportunity to see old photodo site.
Thank you, photodo
