Asahi Pentax S3 Camera Value Guide

The Asahi Pentax S3, produced between 1961 and 1963, is a landmark Japanese SLR that pioneered the fully automatic diaphragm system. This innovation allowed photographers to focus through a bright, wide-open lens before it automatically stopped down during exposure, making it a highly sought-after piece for vintage camera enthusiasts.

What Is Asahi Pentax S3 Camera Worth?

The typical price range for Asahi Pentax S3 Camera is $140 - $155 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Mechanical functionality of the automatic diaphragm and the accuracy of the 1/1000 shutter speed.
• Optical clarity of the Super-Takumar 55mm f/2 lens, specifically looking for the absence of fungus or 'yellowing' common in vintage glass.
• Cosmetic condition of the chrome finish and the integrity of the synthetic leatherette covering.
• Presence of original accessories such as the leather ever-ready case or the clip-on exposure meter.

How to Identify Asahi Pentax S3 Camera?

• Look for the 'S3' engraving on the top plate for international models or 'H3' for those originally sold in the United States.
• Verify the presence of the iconic Super-Takumar 55mm f/2 lens, which was the standard pairing for this specific era.
• Check for the distinctive chrome and steel body construction with the original synthetic leather wrap typical of early 1960s Asahi Optical Co. production.
• Confirm the shutter speed dial reaches 1/1000, a key upgrade for this model over its predecessors.

History of Asahi Pentax S3 Camera

Introduced in 1961 by the Asahi Optical Co. of Japan, the Pentax S3 (known as the H3 in the United States) was a milestone in camera design. It was one of the first cameras to feature a fully automatic diaphragm, which allowed the lens to remain wide open for focusing before stopping down to the selected aperture at the moment of exposure.
