Nikon's compact 35mm AF zoom — 35-70mm f/3.5-6.5 lens, DX coding, four flash modes, CR123A power, 1995.
The Nikon Zoom 310 AF was a compact 35mm autofocus zoom camera introduced in 1995, promoted at the time as the most compact camera in its zoom class. It slotted into Nikon's consumer point-and-shoot range above the fixed-lens models, and a Zoom 310 QD variant added a quartz date back for imprinting the date on the frame.
The lens is a 35-70mm zoom of four elements in four groups, with apertures of f/3.5 at the wide end and f/6.5 at 70mm, paired with a programmed electronic shutter and autofocus down to 60cm. DX-coded films from ISO 100 to 800 set automatically. Four flash modes were offered, including anytime flash and slow sync. Power comes from one CR123A/DL123A lithium cell, and the body weighs about 200g.
It suits film shooters wanting a small, fully automatic compact with a little framing flexibility beyond a fixed lens. The slow f/6.5 telephoto end pushes it toward flash or bright light indoors, but at the wide end it is an easy street and travel camera with genuinely pocketable dimensions of roughly 117x63x36mm.
These are battery-dependent cameras: without a CR123A nothing works, so confirm power-up, flash charging and motorised film advance and rewind. Inspect the film-door light seals and check the zoom action through its range. QD-back examples should be checked for date-display LCD bleed, though the date function is cosmetic to most users.
