It can be done on le cheep:

Image

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.

Image

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.

Image

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.

Image

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.

Image

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:

Image

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.

Regards,

Doc Sharptail

The 135Q shot came out great! SW

Yeah, it did if you aren't sniffing pixels with your nasal cilia.

I have used the 135 Q a bit on film, and it is a fine lens when used as designed for.
It is one of Nikon's earliest f-mount lenses, albeit a slightly budget version with the slow aperture.
The early single lens coatings give a warm edge that is not seen in later lenses.
The lower corners suffer on an extension tube with it though:

Lower left corner is just barely legible compared to the sharp contrast of the printed letters along the top of the image.
It is one of the sharpest lenses I have.
It is too bad that I cannot mount it directly to the D-810.
I would have to modify the aperture ring to get it safely mounted.
It is fine on the earlier cameras that I have- the 2 FT nikkormats and the 2 F-2's.

Regards,

Doc Sharptail

I have another extension tube set, mentioned somewhere previously here- probably on the Something New page.
It is a little bit more spendy.
It aperture couples to the camera, and there are gold-plated A/F contacts inside it which I will likely not be using in the fore-seeable future. :P

At any rate, it is interesting with some of the older vintage lenses I'm enamored with.
This set all with Nikkor "H" 50mm f2, ISO 200 and f5.6 on the shortest tube of the set- 12mm.

Image

This is after nine days without rain.
Public street planter flowers.
Nothing outstanding in terms of sharpness- it's definitely not a modern lens.
The color rendering and contrast with this old glass is the real standout.

Image

100% center crop of the image above.

Image

High key subject in brilliant sun.
I normally avoid this sort of thing, especially with out an external meter.
Just a for the heck of it we'll see shot.
Slightly manipulated in post for contrast.
55% crop.

Image

Un-touched straight out of camera fine j-peg, except for slight crop and re-size.
This dark flower is suffering from some kind of spider related blight, as well as thirst.
An extreme example of the way this single coated lens sees color, but still interesting to me.

I of course need to run a parallel test with the "K" based A/I 50mm f2, which was previously my "go to" lens...

Regards,

Doc Sharptail
