Hi Alfred,

as you may know, there is no correct frameline for the 105 in any Leica. If you want to use the built-in finder you can choose between the 90 and 135 adaptor (those from Leica or Voigtlaender are easily obtainable) - then either choose the outer 90mm or inner 135mm frames.
If you will use an external finder, the choice of the adaptor doesn't matter, any one will do.
Be aware that some LTM adaptors don't couple correctly with distances less than 1.8m (I have one myself and encountered another one already). Better stick to quality material (Leica and Voigtlaender) here.

I'd use the 90 frame and adapter.

The 90mm framelines of the M3 are almost 100% exact for a 105mm lens at working distances of 10-25 feet.

I use the Leica 90 with mine for portraits and it works great.

I guess it is a lens for a SLR Nikon, if so you need a Leinik-M adaptor from novoflex.

The 90mm LTM to M adapter is what I use with my 105 f2.5 LTM....What is cool is the lens has a 52mm filter size; so your modern day 105mm Nikon lens hood works on the 1950's 105mm Nikkor LTM.... My 105mm F2.5 LTM and 90mm LTM to M adapter (Leitz) couple correctly to my beater grade M3 all the way to its closest focusing distance of 4 feet...I am puzzled about Kai's comment that "some adapters will not couple correctly to 1.8m".....The lens feature that couples to the rangefinder is on the lens; and not the adapter.. The adapter only mates the LTM lens to the B bayonet; and also have different features to key to the viewfinder brightlines.... Kai; are you meaning parallax error instead of focusing??? --regards Philip
