Asahi Pentax Spotmatic

Asahi Pentax Spotmatic SP

Why a Spotmatic?

It was the first SLR that I had in my hands, I should have been about five.
My uncle Jorge bought one with a lot of accessories. At that moment I decided that SLR was the kind of camera that I was going to use when I grew up.
In fact I've been using SLR cameras for more than twenty five years.
It took me more than forty years to get a Spotmatic.
Now, thanks to my parents, who gave me one for my last birthday, I have this beautiful black specimen.

Some Facts about it:

The Pentax Spotmatic was presented in Cologne at the 1960 Photokina, as a prototype, by the Asahi Optical Co. Ltd.
This prototype had in fact a spotmeter, that gave the name to the camera.
The production version, that was introduced in the market in 1964, had an average meter, that later was substituted by a centre weighted one.

The Spotmatic was one of the pioneers of the TTL metering and became a cult camera among both professionals and serious amateurs.

An interesting fact is that the Asahi Optical Co. Ltd. changed it's name to the name of its product: Pentax Corporation.
The name Pentax was given to SLR cameras with a pentaprism, as opposed to the older models, with waist level finder, the Asahiflexes.

Main Features and review:

In the picture above, you can see the double flash pc sockets, for electronic flash or flash bulbs, and the exposure meter switch, marked SW.
When it's on the up position it closes the diaphragm, on the lens, to the chosen aperture and gives us the light meter readout.

In the picture on the left the meter is on and the diaphragm of the lens closed to the chosen aperture.
You can see now that the meter needle is between the brackets.
When the shutter is released the lens diaphragm opens and the meter is turned off, automatically.

This is called stop down metering.
It also allows to check the depth of fileld, once the diaphragm is closed.

On this top view you can see, on the left, the film rewind crank, surrounded by a film reminder, the prism casing, with some abrasion marks, made by an accessory shoe.
On the right, the shutter speed selector, that doubles its function as ASA selector by pulling it up and turning to the value corresponding to the film we are using. The shutter index, turns to red if the parameters of film sensitivity and or shutter speed are out of the meter range.
The shutter release and barely noticed, by its right, the reminder of the film advance state, if it's black the film it's not yet advanced, if it's red it's ready to shoot.
Finally the advance lever with the exposure counter. This exposure counter is reset when the film door is opened.

What can we say about this side, we have the iconic SPOTMATIC  logo, the self timer lever and the amazingly sharp SMC, from super multi coated, Takumar 55mm 1:1.8 lens.

Even the lens cap is great.

This is a very nice and perfectly usable camera. With its forty something years of work it still delivers a pin point metering, with an adapted battery, the shutter speeds are perfect and the lens is sharp.
Another positive point is that I can use all my m42 glass with it and I have some.
In conclusion I'm very pleased with this camera and its results, that you can see on the end of the page.
