With how well the 300/2.8 and the 80-200/4.5 did on the Zf, I had started thinking about the matching teleconverters. I was mostly interested in the TC-14B, but any of the main three would do. I had to get out of campus yesterday...it was super busy and one of my coworkers was being a giant jerk...so I went off campus for lunch. Right next to the taco place was a mom and pop thrift shop. I had a few minutes while I was waiting for my order so I popped in. I usually only look for vintage stereo gear and camera stuff, so I went to the back of the store first (stereo stuff). They didn't have anything good, so I peaked into their glass case. Hiding in the back, behind a pair of boots and some costume jewelry, I could make out Nikon. I asked to take a look at the Nikon stuff and it was the TC-14B, TC-201, and TC-301! They were all in very nice condition so I asked how much. She said they had been in there for almost 10 years and since they weren't lenses and were "broken" she said I could have the lot for $100. I had $80 in cash and she took it! I looked them up and only the TC-200 is selling for under $40 on eBay. The other two go for around $100 each. I got lucky! Might have to try my hand on some birding.
Oh yeah, that nice weather. I left Great Lakes Naval Training Center in the middle of the winter of 1980/81 and went to San Diego. Was supposed to go straight to Connecticut but in true Navy fashion they changed the school location to San Diego. I remember getting there and had to buy clothes because all I had was winter clothing.
Super nice weather, but the Pacific waters were still too cold

Congratulations Kevin, it is good that bargains still exist, the internet info and ebay almost killed them all.

I used to surf in Santa Cruz in December, had to wear a wetsuit hoodie to avoid ice cream headaches, and booties to be able to feel your feet.
I may have told the story 100 times, but one day long ago while surfing with no booties my feet were numb and I was stepping on sea urchins without feeling it. When I came out my feet were full of maybe 20 spines, they are not very strong so they did not go deep, was able to take them out by pulling them with a razor.
A week later I was with my boss in Aix-en-Provence, and asked to a surprise local raw seafood.....guess what they served me...they actually tasted good, mild but good....we don't eat them in California.
I am sure I have posted this old film scan before. Shorts were shorter then
An industrial monster still in production, with cam focusing so it is a bit hard to set it, but of course a master of sharpness and easy for the F mount version to deploy on Z cameras (hard to mount on F and it sticks out too far for any good use, there are several other industrial mounts, not too practical).
On the Zs it will focus from infinity to, I guess, 1/2x and exceeds the camera resolution at all distances.
Just for Kicks here is a spine lens sharpness test at 1:4 - prickly!
(Full size on Flickr)
For more kicks here is the same photo I took with the 8.5cm 2.0 rangefinder, this was at 1:2.8 so there is no comparison, my real point is I like the photo below a lot more! even though it is not sharp enough to poke you.

You are not kidding about the sharpness of that lens! That’s a very unusual lens that I’ve never seen before. What was/is the lens purpose? Macro? Super flat plane with no distortion?
And that's just the 105's !!
A friend has a great collection of shotguns and his great fear is that after he dies his wife will sell them for the price he told her he paid!
Laura, looks like the worst is behind you and are on the mend. Wish you a super speedy recovery!
A bit more of my fave structure in Rome, The Pantheon. Commissioned by emperor Hadrian, completed in approximately AD 126. It is amazing that it has been in continuous use since its completion, probably the reason it is so well preserved.

It is not a regular photo lens, this is what Nikon says about it:
Features
Rayfact MJ 90 mm F4: Variable magnification range of -0.05x - -0.5x
For high resolution, large-sized line and area sensor cameras.
High performance guaranteed in all range of magnification.
Aperture lockable screw and floating ring lockable screw for easy use.
Unit sells with a wide range of mounts to fit in your camera.
Applications
Image receiving process by both line and area sensor cameras
Flat panel inspection
PCB inspection
Wafer inspection
Printed materials inspection
The image size is 86mm, more than twice the diagonal and 5.7 times the area of the Z sensors, great for George's use of large format sensor cameras, at the sensor pixel spacing of the Z6 it would support 136 megapixels for the 86mm image size.
My copy has an F bayonet and the way I mount it gives me about .5X to infinity, which is pretty much what it is designed for: 1/20x to 1/2x. The difference between 1/20x and infinity focus is insignificant for resolution on a Z sensor. Lens is heavy, my only complaint is that the lens is intended to be locked with a fixed focus in imaging equipment so it does not have a helicoid, but a cam and locking screws, it is still usable but not for anything that moves, stepping it for image stacking may be a challenge unless mounted on a stepping track.
There are many for sale in eBay at all kinds of prices, I paid $400 for mine in perfect condition.

So it would be perfect for one of my projects that I want to do. I have a few bibles from the 1800’s that have beautifully hand painted illustrations inside. The outer leather covers are totally disintegrating, but the pages inside are still in great condition. I also have a family album that is even older that I want to document. What I have planned to use is my EL Nikkor 100/5.6. I need a bellows or helical for focusing.
Is the optical assembly internally one unit and moves together with the focusing unit? You piqued my interest with the stated image circle. I am wondering if I could remove the optical unit itself and mount remount it for use on a technical camera with a digital back.

Not sure exactly what you mean about the movement of the focusing unit George, so let me describe it:
The lens assembly rides inside a thick heavy aluminum tube, once mounted you turn the heavy outer tube to focus......however... different lenses move in different cams that ride in the outer tube, it spaces the elements differently as you focus.....I think if you remove it from the outer tube it would not be able to focus properly.
There are many screw type mounts that this same lens and other Rayfacts come in, Mine is F, but there are the following mounts and backspaces:

Kudos to Kevin on being awarded Nippi through Rafael's generosity! With the lens now out of my hands and back with Rafael, and being currently between sets of summer photos to process, now seems like an appropriate time for me to post some images from that lens. These were taken at nearby Jack Point with Nippi mounted with an adapter on my converted Fuji X-T2.
Thanks. That answers my question. The optical elements move independently of each other as floating units while focusing.
You just saved me some money

So I have been working out the little mechanical defects on my C3, the only one apparently left are small power steering leaks, the system is an old complex design with pumps, control valves, pistons and lost of hoses, all components are relatively new but it may leak at certain positions only, so the mechanics do not see the leak. Will look seriously into a replacement modern system.
Took the car to Julian a 'mining' mountain little town in San Diego, it was sunny and 80F, the car climbed to 5,000 feet not exceeding 190F in coolant, tracking the curves with the new control arms and purring like a kitten, roaring when passing, sunscreen and top down.
People go to Julian as a fun mountain drive with a destination full of pies, beer, local wine, and cider. Motorcyclist love the San Diego County mountain and desert roads. If you take the main two lane ones it will be slow going with all the traffic, but there are many secondary roads.
This thread is not about C3s but it is about Nikkors, took a lens no-one seems to use - the 45mm 2.8 auto Nikkor C., I will spare you how this lens can couple the aperture to the focusing ring to provide proper flash exposure for the old single intensity flash as measured by its guide number. As flash intensity diminishes with the square of the distance, the lens does not focus on a linear helicoid but a non-linear cam which is nice and smooth, a little weird on the fingers as it moves different amounts depending on the distance.
It is a neat little lens that makes for a light Z outfit, at 2.8 the edges get a little soft, but from there down it is decent.

On the way there is this realtor in the town of Ramona who owns several old Corvettes and other cars, they are not precisely pristine and seem to always be outside, but it is a curious sight:
