Infinity focus on Nikkor 10.5mm

I brought this topic out of the other thread.

Smooth can you describe a method for finding the real infinity focus point on the Nikkor 10.5mm

Gen.Lee,

Really this can only be done with eye sight. But in two ways

  • Looking through the view finder on a distant focal point until as clear as possible.
  • or by shooting a series of shot with tiny increments around the "infinity" mark of the lens and then comparing these shots at full view zooming in on the distant object you chose as the focal point of interest.

On mine when fitted to a Canon camera the infinity is just before the infinity mark on the lens (around 1mm before) of course this can and most likely will vary from camera to camera and lens to lens.

Regards, Smooth

Is this still the way you are fitting the lens to a canon

With a Chinese adapter ring my optimal distance is at the 5 from
0,5.
It's not infinity but it gives the best result.

Yes, it is the way I still do it. "If it isn't broke, don't fix it!"

It is still the easiest most practical way to do the conversion and works a treat. Albeit, you must take care when using this system not to go past the point and detach the lens when fitted to the Canon body.

Finding the real "infinity" mark as stated above is simply best done with eyesight comparison. Be it on a Nikon or Canon camera body. Once you find the correct mark, make note of it.
