Nikon F Photomic T (1965–c. 1967)
The Nikon F Photomic T sits between the original non-coupled Photomic finder and the later FTn. Introduced in 1965, the "T" stands for transistorized - the meter head uses a transistor amplifier circuit instead of the earlier passive bridge-balance design. It reads through the lens with a CdS cell in the viewfinder (with a window for the cell on the front of the finder). Unlike its predecessor, it couples to both the shutter speed dial and the aperture ring.
Metering is full-field with no center weighting. You set exposure by aligning two needles in the viewfinder. Period users and modern collectors alike describe this match-needle system as finickier than the FTn's later 60/40 averaging. The viewfinder itself is bright, with 100% coverage and 0.91x magnification, which makes it excellent for precise composition. The meter reads an ASA range of 6-6400 and covers EV 2.5 to EV 17. Shutter speeds run 1 sec to 1/1000 sec plus Bulb, with FP, M, and X synch up to 1/1000 sec.
The finder sits between the original Photomic and the FTn in the family line. The FTn arrived in 1967 and has a different coupling shoe and a different metering pattern. The Photomic Tn is a follow-on variant mentioned in research, though the precise differences beyond coupling shoe and metering pattern aren't well documented.
Collecting one today comes with caveats. The meter originally ran on two PX-400 mercury cells, now banned. Modern users typically adapt silver oxide or zinc-air batteries, but exposure accuracy varies. The CdS cell is known to degrade with age, the meter needle can stick, and the coupling arm between finder and shutter dial can wear. Replacement CdS cells aren't made, so parts must be scavenged from donor cameras. On the positive side, the meter calibration can be adjusted via a potentiometer inside the finder, though it's delicate work. Foam light seals on the back are a routine replacement.
Prices on completed eBay listings generally run $150 to $450 depending on condition and whether the meter works. No original price or production numbers are documented, and the record is thin on dimensions and weight.
