The chrome NKT 35mm finder with no brightlines is an excellent finder with a manual parallax correction cam and it fully covers the 24x36 format. If you wear glasses you can see the whole frame for composing with no problem. Basically, what you see in that finder is what you see in the Nikon Varifocal finder once set to 35mm. It's very similar to the Canon chrome finder looking almost the same externally.
Note : the Nikon S has 24x34mm frame (the 24x32mm frame belongs to the Nikon One and the Nikon M).
There are lots of excellent 35mm finders out there, from the prewar Zeiss 432/5 finder (still remarkable even by modern standards) to the recent CV brightlines finder, of all specs., sizes and budgets. This is not a difficult hunting.
Thank you, Nicolas, for correcting me.
Neither the Varifocal nor the chrome Nikon 35mm finder are satisfactory in use. Even the Nikon 35mm brightline finders aren't perfect, because the brightlines are straight but the finder distorts (barrel). The best finder in my opinion is the Leitz SBLOO, altough it is rather large. Unfortunately I do not know the Voigtländer 35mm brightline finders.
The brightlines of the SBLOO anticipate on the barrel distortion of the finder, they are curved, so they are easy to use.
