This genuine Nikon flashgun has TTL dedicated auto flash control, and is suitable for many Nikon AF and selected manual focus SLR cameras, but not the F55 or any digital models.
It's in good used condition(we haven’t tested it with batteries), and comes in the original box and a copy of the instructions.
The guide number is 20 (meters) and 65 (feet) with ISO 100 film. This gives a theoretical maximum range of up to 11m (36 feet) with an f/1.8 lens, and these distances double with ISO 400 film. The flash covers lenses down to 35mm.
The flash provides fully automatic, dedicated exposure control, with TTL auto or full power manual operation. Thyristor circuitry provides faster recycling and more flashes per set of batteries at closer distances in auto mode. Dedicated flash control with auto setting of shutter speeds and/or apertures, and viewfinder flash ready indication with suitable film cameras (see below). TTL auto flash works through the lens while the shutter is open for the most accurate exposure possible, at any aperture and taking account of filters, bellows and other factors automatically. Please note that the flash doesn't have an external auto sensor, so on non-TTL cameras it will only work on full power (manual)
The rear of the flash has a comprehensive exposure table with film speeds from ISO 50 to 400, apertures from f/2 to f/16 and distances from 0.6 to 10m (2 to 32 feet). Ready light provided. This flash is very well made (in Japan) with high quality materials, clear markings and a very good standard of fit and finish, as you'd expect from a Nikon product. It even has a serial number, which is increasingly unusual for flash units.
The flash measures around 113x66x42mm (4.5x2.6x1.7 inches) and weighs approximately 145g (5oz) without batteries.
It takes 4x standard AA batteries including disposable alkaline (supplied) or rechargeable NiCd and NiMH types. The battery compartment cover is semi-captive so it can't easily be dropped or lost. There's a standard hot shoe fitting, with locking wheel for secure mounting.
An excellent little flash unit for many Nikon film users.
