Hi Guys,

I received a very attractive offer for a Nikon lens.

The reason for this is the bent filter thread.

Now I've researched the lens using the serial number.

It's about the Nikkor 50mm f2. Minimum focus distance 0,45m



I thought I found the lens at Ken Rockwell and in the photosynthesis database, but none of the lenses there has an aperture of 22.

The seller says that he doesn't know why a 22 is printed on the aperture ring. In any case, the aperture can only be closed to 16.

I hope to find someone here who is familiar with this lens or who may have a theory about the aperture ring.

The aperture ring looks like it is from a different lens. I do not see the secondary aperture scale, and I do not see the AI ridge on the back of the aperture ring.

Can you post a shot from the back?

I suspect the lens was damaged, and that ring was replaced.
 
Thanks you all for the answers!

Interesting, Richard de Stoutz (who has an exelent website!)has 37000001 and f/16.

f22 came with the 1,8 version.

Maybe a misengraving?

A friend of mine had the same assumption. Possibly a production error when changing from the 50mm f1.8 to the 50mm f2.

I don't like to rule it out, but somehow I can't imagine that the lens would have gone through quality control or a customer wouldn't have sent it back.

I've attached a photo of the back here on this post.

Okay, so we're getting closer to it.

Meanwhile I also assume that two lenses were tinkered together to one lens which is then in working condition.

Your photo shows it is a 50mm f2 AI lens with a pre AI aperture ring, with AI prong. I still think the ring has been taken from a 35mm f2. Because of this mod it is effectively a pre AI lens at the moment, so less useful than an AI lens. How do you plan to use it? You could, of course convert it to AI yourself or get it converted. It isn't worth a lot so I wouldn't spend a lot on it.

Check out the back of a 50mm f2 AI here..... https://www.destoutz.ch/lens_50mm_f2_3700001.html
 
More or less echoing the answers already made:
This is not an AI lens.
Both my non-AI and AI 50/2 goes to a max of F:16
This is not how it was shipped from the factory - it is modded later with another aperture ring.
Where I live the 50/2 is quite cheap, thus I would want a significant reduction in price or I would pass and find another normal one.

Thank you both to bring it down and for the clear advices !
I have no lense knowledge but vintage Nikon Lenses are pricey here in Germany.

50mm lenses are offered in a price range around 120 Euro in near mint condition.

I bought a Nikon FE and have also a Nikon D3100.
Primarily i need a lens for the analogue Nikon but it would be great if I could use the lens also for my D3100 in manual focus.

I would like to use the Nikon FE primarily for night photography / long exposures.

The Nikon FE is said to handle night photography in automatic mode very well.

I can get the fakey Nikkor 50mm f2 lens for 40 EUR.
 
You should be able to use the lens as shown in Stop-Down metering mode on the FE, and use it on the D3100 in full manual mode, manual focus, manual exposure. I don't think the meter will work with it on the D3100.
 
Who knows what else has been tinkered with on this lens? I would stay away from it - there are plenty others out there.
 
Hi guys, I finally got my first analogue Nikon:

Nikon FE with a 50mm f2 lens (yes the lens with the ominous aperture ring).

The camera is in very good condition and everything seems to be working correctly as designed by the engineer.

The lens seems to be ok so far. Apart from the aperture ring already discussed here, the focusing ring runs nice and smooth and the aperture ring clicks nicely when you adjust it to a different f-number.

Only light metering gives me a headache.

Probably unfounded, but photography has not really been my hobby for long and therefore I lack the experience to be sure that everything is ok with the camera or lens.

The thing is, I don't understand the exposure metering.

To shorten it a bit, here are the following questions:

1. To get a correct exposure time, do I have to use the exposure time that I get when I press the "Aperture preview"?

2. How does the camera determine the correct exposure time in automatic mode without using the aperture preview?
Do I have to hold down the aperture preview when the shutter button is released?


Thanks in advance for your answers!
 
To get a reading, stop down the lens using the dof preview lever.

Stop down process from mir.com.my:

For automatic diaphragm lenses with no coupling ridge:

AUTO: Hold in the depth-of-field preview lever to stop down the lens diaphragm. Then, adjust the aperture ring until the black meter needle indicates the desired shutter speed. Trip the shutter with the preview lever fully depressed toward the camera body until the completion of the exposure. An alternative way is to use the built-in memory lock function [note -- memory lock: press the self timer lever towards the lens.] In this case, after reading the meter in the same method as mentioned above, use the memory lock to freeze the reading (be sure the preview lever is still depressed when “locking in” the reading), and then free the preview lever. Release the shutter while keeping the memory lock depressed.

MANUAL: Select the desired shutter speed, depress and hold the depth-of-field preview Lever, and while keeping it depressed, adjust the aperture ring until the needles in the viewfinder overlap. You may free the preview Lever before releasing the shutter.

1. Since your lens is not an AI lens, you need to press the aperture stop-down lever (preview) to determine the proper exposure (proper aperture for the shutter speed you've chosen). Once you know the aperture /shutter speed combination, you don't need to hold the lever down when you make the photo because the aperture ring is already at the proper aperture even though the blades are open. When the shutter is tripped, the blades will automatically close to the selected aperture on the ring.

2. With an AI lens, you meter wide open even though you turn the aperture ring. When you turn the ring, a ridge at the back of the lens tells the camera which aperture is being selected even though the lens is wide open. The camera's exposure system looks at the wide open reading and then knows whether the aperture you've selected (based on the ridge position) would be underexposed, overexposed, or correct.
