I have found some Nikon lenses are using rear focusign system, where front stays static. All of them are quite modern, and I was wondering if ther eare any vintage ones in the 35mm range that focus by moving jsut the rear element?

I believe the first (or one of the first) rear focusing designs was the 80mm f/2.8 AF lens for the F3AF (released in 1983).

How vintage are you thinking?

Thank you, this is great!
I am looking for a set htat has no green in the coatings. some AI and AIS seem to have had a purple/blue coatings with orange, which I am after.
Do yo uhappen to know about anything in the 35mm range? That 80 2.8s is actualyl very interesting, but has green in the coatings.

You sparked my curiosity. Why are you looking for rear focusing Nikkor lenses without green in the coating?

Because this is for video purposes. Typically when you hit bright light soruce the lens flare take the color of the coating, and in motion attracts a lot of attention. I generalyl don't like green flares.
Rear focusing because I plan to use a system of filters in front of the lens that barely fir the 35mm angle of view. If lens is rear-focusing entrance pupil does not move as much during focus, so I will avoid vignetting like that.
Now question is if such lenses exist in 35mm. Does not have to be Nikon actually, any 35mm that is rear docusing would do.

The color of the coating is based on the lens' design. Nikon's goal is to have uniform color balance throughout the entire Nikkor line-up.

Some super-telephoto mf Nikkor lenses, such as 300mm f/2.8 AI-S, have internal focusing and the front element/s stay still. But as far as I know none of the normal lenses focus that way. The way most mf lenses work is by moving all of the elements away from the film plane, because there was no reason not to do this for still photography and it was much cheaper than making a lens with internal focusing. There are some wide angle lenses with close-focus correction but the front element is still moving forward and backward as you focus.

Strictly, rear focusing is different from internal focusing. The 105/2 DC and 135/2 DC lenses have rear focusing. The 28/1.4 D lens and the super telephoto lenses have internal focusing. A lot of the Nikkor professional lenses from this era have a plain glass (i.e. it is not an optical element) element at the rear of the optical system - presumably to stop the focus vacuuming dust into the barrel. Rear focus is more susceptible to chromatic aberrations, but Nikon controlled these pretty well. Most of these lenses are ~30 years old and aren’t as technically capable as the newest Nikkors.

Hmm, mm, well, I think the OP needs to re-examine some concepts regarding coating of lenses. Green flare from green coatings makes little sense, since actually seeing a Red coating means that Green would be the flare. Or its 1/4 to 1/8 wavelength. Since it will be used on "video" (multi frame digital) the sensor, sensor filter stack and the coatings on those will most likely have a more visible effect on creating flares. Good luck getting reliable information about sensor filter stack coatings.
That being said, to answer some of the OP questions; Post F Nikkors up to Pre-K Nikkors and some K and Ai versions of Nikkors have the desired 'red' coatings on the front elements; most notably is the Nikkor 50mm S.C in F (Pre-Ai) and very early K series. (http://www.photosynthesis.co.nz/nikon/lenstype.html).
No Nikkor 35mm prime has rear focussing, which was developed for the AF Nikkor 85mm f/1.8 (https://imaging.nikon.com/history/story/0032/index.htm).
I would think the way to go with the addition of filters is to use a Matte box to add on filters.
In regards to flare color and control, the only true way to see what flares are created is to actually use and test the individual optic. Each lens within each lens makers line and as well each lens maker has their own 'special sauce' and results will vary from each maker and each lens design. Nikon and others fine tune the coatings to be consistent (for each generation of coatings) lens to lens, and series to series, (meaning similar era Nikkors will mostly match in color).

Interesting, about the effect of coating color on flare color. Note also Noserider's remarks about that. I'll be following with interest.

Additional thought; I seem to recall that the flare-tastic look of the Remake of Star-Trek was enhanced further by an intentional shining LED of certain colors onto the front element of the anamorphic cine lens, so if that look is desired the OP may want to try that.
