Question for F experts: metering dial

[jeroen dommisse]

I have a Nikon F Photomic T with a serial number in the

67xxxxx-series. Research tells me that the Photomic prisms from this

era go from ASA 10 to 1600, whilst the dial on mine goes from 25 to

6400. I'm a bit puzzled. Anybody who has a clue about this?

Jeroen,

 

I'm puzzled too. The only Photomic meter to have 6400 ASA is the FTn (6 ASA to 6400 ASA)

 

If you don't get an answer here, maybe some old guy in the Classical Photonet forum could help you.

 

Greetings.

Hello,

My books show the following;

Nikon F Photomic, 10 to 1600 ASA -

Nikon F Photomic T, 25 to 3200 ASA later changed to 20 to 6400 -

Nikon F Photomic TN, 20 to 6400 ASA -

Nikon F Photomic FTN 6 to 6400 ASA

I can confirm Bill's informations. My source says the same.

I'll post some photos in the morning!

My 1965 (Tn-era) Cooper and Abbot handbook says both the T and Tn came in 20-6400, but their illustration shows a T with a dial clearly marked 10-1600. They also mention that the mode for indexing the lens changed during the production of the T (earlier ones require turning the inner dial, later require lifting and turning the outer ring). I'm guessing that the two changes occurred together.

So here it is:

It looks as if my surmise above was incorrect, since it looks like the earlier version of the setting ring, but the later ASA range.
