It can be done on le cheep:
From my 3rd party aftermarket extension tube set.
This is the shortest extension tube possible out of the set.
It is glassless, so no worries about non-nikon optics here.
It is well made, and appears to fit precisely square and tight.
I ran a brief, hurried, hand-held test with it tonight on the D-810.
All are shot wide open at max aperture.
On board flash and ISO 400.
These are the lenses I used, and not just another excuse to post more lens porn.
Left to right:
Nikkor 200mm F4 from the late 70's to early 80's, Nikkor Q 135mm F3.5 from '59 to about '63, and Nikkor Q.C. 200mm F4 from about '64 to the early 70's.
Test shot from the modern 200.
It ain't too bad, with minimal light fall-off to the corners.
Image center is at "Black and White" on image for all of these.
Subject area is roughly 4 inches square.
Test shot from the oldest lens of the lot.
The Q 135mm shows distortion, fall-off and fringing in the lower corners.
It is a much better lens when used normally, without extension tubes.
Big surprise here is the Q.C. 200mm.
It is very nearly the equal of the modern 200 above.
Apart from some very slight fall-off near center, I can find very little wrong with this lens.
There's another method I may get into laterer:
The reversing ring.
It works very well with normal to semi-wide lenses.
It can be done with a telephoto, but I'm not real crazy about how close the rear element gets to the subject with long lenses.
