Here it is on the Nikkormat FT-2, which is wearing the body-half of it's leather ever ready case.
That case half provides very good grip.
What's interesting here is that the slide copy unit is set up to handle 35mm roll film as well.
I may be able to play around somehow with B&W negs with the D-810...
Shown with my high mileage 55mm f3.5 Micro-Nikkor aboard, which was one of the design intentions.

Image

This unit is fairly devoid of markings.
It pre-dates Nikon's penchant for letter/number model designations.

Image

Serial # location under the rails.
Nikon was not first out of the gate with these.
I think Asahi came out with them first.

Image

Branding on the other-wise unmarked slide copy unit roll film pan.
The bellows and slide unit are incredibly well made.
It is all s/s, aluminum, brass, and leather.
I can't find any plastic on it anywhere except for the diffuser on the slide copier.
That may not even be plastic either- there's a possibility it's bead blasted glass.

Image

One of the first images taken with it.
Vignetting is due to over extending the bellows beyond the camera's image circle.
Backing off 2 or 3 mm on the bellows clears that right up.

Where this system beats extension tubes is that there is a bit of focus distance range with it.

I have a lot of reading to do on this.

Regards,

Doc Sharptail

That would be just the ticket for copying ranching pics Dad took in his cowboy years. Unfortunately, there isn't much interest in them from the younger generation. SW

I am going to find out what I can on digitally reversing negative images.
It may take a while.
I don't have much of a negative file left anymore.
What survived the fire was very badly heat bled. Some of the chemical stabilization simply evapped off.

There is one more item to complete this unit, and make it much easier to use~ a rail for focusing that moves the whole works in and out on a tripod head.
Using this unit hand-held is quite a challenge.

Doc Sharptail

thats a unique item that i did not realize existed - could have used it a couple times back in the 70s , how complicated is it to operate ?

It's a bit trick getting it on to the D-810.
Once it's mounted, use is not that difficult.
There is no automation to the aperture at all, or communication with the camera.
Viewfinder image is a bit dark- especially stopped down- external lighting sources help a lot.
From the testing I've done, f5.6 or f8 seem to work best in terms of image quality.
High ISO settings are a must with this for hand held work.
The length of the bellows interferes with on-board flash.
A remote unit, or a seperate head with a coiled sync cord to the camera are a huge improvement in image quality.

From the bit of reading I've done on the MIR site, the 105mm should achieve infinity at some point, unless the translation on that site is poorer than I recognize.
I don't think I can go heavier than the 135 "Q" with this rig.
It is quite light in construction compared to the later variants.

Doc Sharptail

Series "E" Nikon 100mm f2.8
Other than a slight divot on the filter threads, I can find little wrong with it.

Image

At infinity...

Image

...And minimum focus distance.

No, it's definitely not a Nikkor- we'll get that cleared up right away.
It's a first variant "E", and has some favorable reviews for it's image taking ability.

The plastic on it is a detraction.
The focus ring turns a bit stiff- they did when new, so no real concern there.
The plastic aperture ring-uggghhh!
At least the clicks are positive, on the stiff turning ring.
As to the images, a few very hurried samples.

Image

Fluorescent sign frame at f5.6.
Some slight pin cushion here, but not really noticeable unless you are looking for it. At a little over 100 ft.

Image

Dirty windshield shot at MFD and f5.6. Close to the markings on barrel.

Image

Hefty crop of the same image.

Image

Purple Loose-strife growing under a dead jack-pine. f5.6.

Image

Crop again.
Colors a bit on the muted side, but still interesting rendering.

What gets me about this lens is the dimunitive physical size.
It's not much bigger than the nikkor 28mm f3.5 A/I-s

Regards,

Doc Sharptail
