Pentax K (Tower 29)

The 'S' model, was soon followed by the 'K' model, which improved the top shutter speed to 1/1000s. More importantly, the 'K' model introduced the first version of what was called auto-aperture: With the new Auto Takumar lenses, the camera would stop down the aperture to the shooting value just prior to firing the shutter. One then had to manually open up the aperture again with a lever on the lens. The later Super Takumar lenses solved this inconveniece - their aperture would open up again automatically after the exposure.

Pentax K (Tower 29) Camera Review

Pros Build quality, size
Cons No meter
Rating 8
Price (U.S. Dollars) $400
Years Owned 3 years

I can recommend this camera: Yes

Value, Features, Performance & Size
"Rating" and "Value" will be somewhat subjective to what someone is looking for. This is a legendary camera and very special to own, but obviously it won't outperform many of it's newer counterparts. Asahi Pentax cameras from this era were all small and well balanced. Regarding performance, the winder is smooth, all shutter speeds are reasonably accurate, and the shutter fires solidly.

Camera Review
I hadn't gone looking for this particular camera, but instead came across it and it looked to good to pass up. The camera looked new, came with the original case, zebra 55/1.8 Takumar lens and caps, so I probably paid a bit of a premium.

From the pictures it looked like a nicely made camera, but being a 50+ years old, I expected it to be a little "clunky". When it arrived, I was pleasantly surprised. The viewfinder was bright and clear and everything worked so smoothly. The next morning I grabbed some film, used my ME Super as a light meter and shot a roll. I presumed I would have ruined half of the roll, but not one shot was under or over exposed. It's a great little camera.

Here is a shot of the camera, and another from the camera.....
