It does read P Auto on the barrel. According to mir. com is the newer type with diamond focus grip. I still don't know how it can compensate since there are no electronics to know what it going on.
Mechanical compensation, cams. "Auto" means auto diaphragm, it stops down when you take the picture and opens back to max. aperture for viewing and focussing, thay all said "auto", standards, wideangles, etc. Yours, if it is indeed the 'K' version, does not have a compensating diaphragm and does not focus to 1:1 without an extension tube. I have the identical lens, there are two ratio scales - one from infinity to 1/2 lifesize, and one from 1/2 lifesize to 1/1 lifesize for use with the tube.
No it doesn't say K, but the barrel has 1:1 marking that is reached when the lens is extended all the way. How much exposure should I add at the most extended point? two stops? 1 stop?
Yes it is P Auto with diamond grip. So, there is no "K" mark? And K version is the auto compensating aperture or not? Please excuse my ignorance with this lens.
This is a quote of my post #9:

As I mentioned, all (and more) of this information is available at the Mir site I linked you to.
There is no 'K' mark on the lens.
OK I see that now. There are two scales as you said. One goes down to 1:2 at 24.1 cm. The other one is etched on the barrel and reads 1:2, 1:1.5 and 1:1 ans it would be used with extension rings. And I assume there is no need to compensate the exposure when at 1:2, right?
Um, er, ah, ignoring complexities due to pupillary magnification not equal to 1.0, the magic formula for exposure compensation given magnification is effective aperture = aperture set (f/ number) * magnification + 1
At 1:2, magnification = 0.5 so you'll need approximately 1 stop more light or exposure time or to open up one stop from whatever the meter says. At 1:1, magnification = 1.0, 2 stops more light or exposure time or open up two stops from whatever the meter says. If your camera has TTL autoexposure it will take care of this for you, whether you want it to or not.

Yes, Thank you very much. I am enlightened now.
By the way, that lens works very well at infinity, and due to the recessed front element it is somewhat self-shading.
E., there are people who disagree with you. Not me, my first Nikkor was a 50/1.4 bought new in March, '70. I got a 55/3.5 in September of that year, not long afterwards retired the 50/1.4 for everything except shooting at twilight.
But, y'know, neither Modern Photography nor Popular Photography ever published a review of the 55/3.5. I once asked Norman Rothschild why not. He told me that in PP's tests the 55/3.5 Micro Nikkor came out unacceptable at infinity at a couple of apertures. I think the problem was coma. PP had a policy of not annoying major advertisers by publishing negative reviews of their products, so never published that test. MP had a similar policy.
If - and this is an important 'if' - you are using through-the-lens metering of any type, you need not compensate the reading you get. I have an FTN finder for my F and the only lens I use it with is my 55/3.5; I bought it for just this purpose.
