Many years ago bought a 260mm f/10 Nikkor=Q lens. Lens is engraved: Nikkor-Q 1:10 f=260mm.
f/10 to f/32 4/4 double Gauss f/10-68 degrees, f/22-74 degrees. Lens only stops down to f/32. Rear element sticks out way past the lens, fortunately have the extended rear lens cap. Have the retaining/mounting ring that is located in the middle of the lens.
From what I have found out:
Lens is actually 267mm in focal length
S K Grimes lists mounting it in a Copal #3 but with the following "Expensive – Risk lies in cutting lens out of mounting bracket"
Front & back elements honestly look like they should cover 105 degrees or more
Presently the lens only stops only down to f/32. Would really like it to stop down to at least f/64
Hand written note found with the lens: "covers 11x14" but unfortunately no source of this info noted.
Testing the optic on my 11x14 will take a lot jury rigging for sure.
Ideally would love to use this lens on my 11x14. Even have a Copal #3 shutter to potentially mount the optic in but not sure if this is feasible... remember one time reading that one of two versions of this optic not being able to be mounted in a Copal #3.
Does anyone have any experience with this lens?
thanks
