Panning using a fully manual Vintage lens isn't the easiest of challenges, but get it right and the rewards are great......I seem to have cracked it here, because he was going at a fair lick quite close to me too.

The lens, was my newly acquired Vintage Carl Zeiss Jena 29-2.8 fitted to my M 4/3 GX8 ..... a lens just right for Street Photography.

Whilst idly twisting the focus and aperture rings, I noticed a small red dot, close to the infinity mark.....I wondered if it was significant?

I set the focus ring to it, then the aperture to f worked, everything was confirmed in focus from infinity down to around 8 feet, making the camera literally a .....Point and Shoot, with everything in focus between those points.

Unless of course one of knows another reason for that red dot?

I love my vintage lenses, and the skills they have forced me to learn.

Another example of my Leica type processing.

If the red dot is fairly close to INF then it is most likely the "Infinity" to use with IR film which stems back to the days well before digital.
Very good panning too

The Wiki in the sky agrees:

Most lenses, however, cant tackle infrared wavelengths and make them focus on the same plane as visible light. This makes it necessary to shift the focus of our lenses when we attempt to shoot infrared film. To make this easier, lens makers have put an infrared mark on most of their lenses to aid in this shift. Exceptions are most auto focus lenses and many zoom lenses.

If you are new to infrared you may not have seen this focusing aid so lets look at what and where it is. As you can see in Fig. 1, there is a red R located on the depth of field scale on the lens. Check your lens. This may be a red dot or an R. As many newer lenses dont have depth of field scales, they probably wont have this feature either.

To focus using this, focus as you usually do, and then look down at your lens. In the middle of your depth of field scale you will see a centering mark. (See Fig. 1 again) This centering mark will be pointing at a distance on your range or distance scale opposite of the depth of field scale.

After noting the spot where this mark is pointing, simply rotate your lens so that this spot is now lined up with the red R instead of the centering mark. For Kodak IR film this will probably be in focus. I say probably because there is room for error when you rotate the lens. You may want to test this by shooting a roll with a wide open aperture, to verify that it really is in focus.
