PENTAX SPOTMATIC II

The Pentax Spotmatic II is a 35mm single-lens reflex (SLR) camera introduced in 1971 as an upgrade to the original Spotmatic. It has open-aperture TTL (through-the-lens) metering and an improved shutter mechanism. It was a significant refinement in Pentax's line of manual-focus SLRs in the early 1970s.

Overview

Asahi Optical Co. (later known as Pentax) released the Spotmatic II in 1971. It was positioned as a mid-to-high-end 35mm SLR for serious amateur and semi-professional photographers. It succeeded the original Spotmatic (SP), launched in 1964, which was among the first SLRs to offer through-the-lens (TTL) metering with standard lenses. The Spotmatic II fixed several limitations of its predecessor, most notably by adding open-aperture metering. That let users compose and focus at full aperture and still get accurate exposure readings without stopping down manually. It was faster and easier to use in changing light, particularly in low light.

The Spotmatic II kept the M42 screw-mount (also known as the Pentax Universal or "Pentax Thread Mount"). That means a vast array of lenses fit, from Pentax and third-party makers such as Super-Takumar, SMC Takumar, and lenses from Zeiss, Yashica, and others. It did not change much in looks from the original Spotmatic, but the insides were refined. The shutter mechanism is more durable and rated for 100,000 actuations. The film advance was redesigned with a shorter throw and smoother operation.

The Spotmatic II played a transitional role in Pentax's move toward fully integrated electronic SLRs. It sits between purely mechanical designs and the coming generation of aperture-priority and electronic-shutter models like the ES series. The Spotmatic F (which offered semi-automatic exposure) succeeded it in 1973, yet the Spotmatic II stayed in production until 1976, which points to strong market acceptance and durability.

Key Features

Historical Context

The Spotmatic II arrived at a time of rapid advancement in the SLR market. The early 1970s brought more competition from Japanese makers such as Nikon, Canon, Minolta, and Olympus, all pushing metering, ergonomics, and automation. Pentax had pioneered TTL metering with the original Spotmatic, and it chose to refine that camera rather than jump straight to automation. The Spotmatic II keeps the mechanical reliability of that platform and adds open-aperture metering.

This put the Spotmatic II in direct competition with models like the Nikon F (with Photomic finder) and the Canon FTb, both of which also offered full-aperture metering. Unlike those, the Spotmatic II stayed fully mechanical except for the meter circuit. A single PX625 (1.35V mercury) battery powers the CdS meter. There is no electronic shutter control, so the camera still shoots without batteries, just without metering. Photographers who wanted dependable performance in diverse conditions liked that.

Collectibility & Value

Today the Pentax Spotmatic II is sought after by film photography enthusiasts and collectors of vintage SLRs. It is not as rare as some limited-production variants (such as the Spotmatic SP500), but it is less common than the original Spotmatic or the later Spotmatic F. That makes it a desirable upgrade path for M42 system users. In good working condition, prices typically range from $150 to $300 USD, depending on shutter accuracy, meter functionality, and lens inclusion.

When buying a Spotmatic II, check the shutter across all speeds, particularly 1/1000 sec, which can become inconsistent in aged units. The CdS meter needs a 1.35V mercury battery (now obsolete), though modern adapters with zinc-air or WeinCell substitutes can restore it. A common problem is meter inaccuracy from aging CdS cells or corroded battery contacts. Cleaning or recalibration may be necessary. Replace the light seals to stop light leaks, and check the mirror bumper foam, since degraded foam can cause mirror slap or damage.

Cameras with original leatherette, clean viewfinders, and sharp focus screens command higher prices. Units paired with Super-Takumar or SMC Takumar lenses, especially the 50mm f/1.4 or 85mm f/1.8, are particularly valuable because of the optical quality and collector demand.

Repair & Maintenance

The Spotmatic II uses a PX625 (1.35V) mercury battery to power its CdS exposure meter. Mercury batteries are no longer produced, so users typically substitute 1.35V zinc-air batteries (e.g., WeinCell) or use adapters with 1.5V silver oxide batteries. The latter may cause slight overexposure if not compensated. Battery leakage is a common problem in stored units, and it often calls for contact cleaning or a new battery holder.

Shutter servicing is occasionally needed, particularly if the 1/1000 sec speed is inconsistent or the shutter curtains show wear. The cloth shutter is sensitive to humidity and age. Replacement is complex and best left to experienced technicians. The film transport system is generally sturdy, but worn advance levers or worn gears can develop play over decades of use.

Regular maintenance includes checking and replacing light seals, cleaning the mirror and focusing screen, and making sure the lens mount's automatic diaphragm pin moves freely. Lubrication of internal mechanisms should only be done during a full CLA (Clean, Lubricate, Adjust) service by qualified repair specialists. The camera is mechanical with minimal electronics, so it remains highly repairable and suitable for continued use with proper care.
