What the Nerds Do / Re: Nikkor 400mm f/5.6 ED IF Ai-S
« Last post by richardHaw on May 04, 2025, 03:40:28 »I specifically selected the non-IF 400mm f/5.6 ED because of the chromatic issues with the IF version. It's much slower to operate, though, so really most suited for landscape work.
Interestingly, there is exact same dichotomy in behaviour - and performance - between the [elusive] Nikkor 300mm f/4.5 ED and the [ubiquitous] Nikkor 300mm f/4.5ED-IF. The former is very sharp, no CA, and operates very very slowly; the latter is also pretty sharp and remarkably fast operating, however with CA issues not unlike the 400 ED-IF. Again, I'm using my 300 ED mainly for landscapes and for IR, since it is one of the very few Nikkors without any focus shift visible-to-IR.
I see...
So it's just not me and my copy. Thanks for verifying it for me.
If you may, do you have links of your photos taken with this lens? I will share them in a gallery in the article
