  No other camera in the world can come close to matching the specifi- cations of the Nikonos IV-A. It's a watertight, automatic exposure 35mm camera that offers a system of lenses and accessories plus dedicated flash operation. Capable of going down
  to depths of 160 feet without a special underwater housing, the self- contained Nikonos IV-A remains totally waterproof. In fact, its extraordin-
  arily rugged construction makes a

Nikonos the ideal camera to use in situations where you wouldn't risk a regUlar camera, from boating to mountain climbing or exploring caves.

The Nikonos IV-A is very easy to use, because exposures are auto- matic. Pressing the shutter release button halfway activates the camera's built-in exposure control system.

A highly-visible LED at the bottom of the bright albada viewfinder glows continuously if the exposure is within the camera's shutter speed range- 1/30 - 1/1000 sec. If the exposure is beyond this range, the LED blinks as a warning to readjust the aperture or use flash. Shutter speeds are stepless and electronically timed for precise exposures above or below the surface. The Nikonos IV-A may also be used at the mechanical "M" setting (1/90 sec.) or "B" for time exposures. Since illumination fades fast as you dive, a flash unit becomes an indispensable accessory. And with the Nikonos IV-A/Speedlight SB-101 combination, flash photography is as easy and mistake-proof as taking an available-light picture. When connected to the camera and activated, the SB-I0l automatically programs the Nikonos' shutter to the correct X-sync speed (1/90 sec.) and activates a viewfinder flash ready-light. The SB-I0l provides automatic flash exposure as well as manual with a power ratio control to facilitate close-up and synchro sunlight photography.

Oversized controls, from the shutter release to the focus and aperture controls on the lens, make it very easy to use the Nikonos IV-A, even when wearing gloves. And, the Nikonos system further extends the camera's capabilities. In addition to the SB-101 flash, four interchangeable Nikonos/Nikkor lenses are available as well as a special kit for close-up photography.
