YASHICA MAT-124G

The Yashica Mat-124G is a twin-lens reflex (TLR) medium format camera produced by Yashica from 1970 to 1986. It represents the culmination of Yashica’s TLR development, combining high build quality, precision optics, and one of the first integrated through-the-lens (TTL) exposure meters in a consumer-level TLR.

Overview

Introduced in 1970, the Yashica Mat-124G succeeded the Mat-124 and was the final major evolution in Yashica’s long line of twin-lens reflex cameras. Positioned as a professional and advanced amateur tool, the Mat-124G was designed to offer exceptional image quality, mechanical reliability, and advanced exposure control in a robust metal-bodied package. It was manufactured in Japan and quickly became the most popular model in Yashica’s TLR series, earning a strong reputation for durability and optical performance.

The Mat-124G stands out for its built-in cadmium sulfide (CdS) TTL exposure meter, a feature uncommon in TLRs at the time. This meter reads light through the taking lens, allowing for more accurate exposure calculations than handheld meters or non-TTL systems. The meter is powered by two PX625 (1.35V mercury) or equivalent modern batteries (such as Wein Cell or adapters using 1.5V alkaline with exposure compensation), and its readout appears in the viewfinder via a galvanometer needle visible alongside the focusing screen. This integration of metering significantly improved usability, particularly in variable lighting conditions.

Equipped with a high-quality Yashinon-DS 80mm f/3.5 lens set (both taking and viewing lenses), the Mat-124G delivers sharp, contrast-rich images on 120 or 220 roll film, producing twelve 6x6 cm exposures per roll. The camera features a rotary film advance with a built-in crank, a significant ergonomic improvement over earlier knob-wind models. The crank is removable and folds flush when not in use. Film type selection (120/220) is controlled via a dial on the back, which adjusts the film pressure plate position to accommodate the thinner 220 film, effectively doubling film capacity.

The Mat-124G was marketed as a premium TLR alternative to the Rolleiflex 2.8F and Minolta Autocord, offering similar image quality at a lower price point. It was widely used by portrait photographers, photojournalists, and serious hobbyists during the 1970s and early 1980s. Its solid construction, precise mechanics, and excellent optics ensured a long service life, and many remain functional today.

Specifications

Key Features

• Integrated TTL CdS Exposure Meter: One of the first TLRs with through-the-lens metering, providing accurate exposure readings directly in the viewfinder.
• Dual Film Compatibility (120/220): Adjustable film pressure plate allows use of both 120 and 220 film, increasing flexibility and number of exposures.
• Rotary Film Advance Crank: Smooth, fast winding mechanism reduces vibration and speeds up operation compared to knob wind.
• High-Quality Yashinon Lenses: Sharp, well-corrected optics with minimal aberrations, delivering excellent image quality.
• Robust Metal Construction: Die-cast zinc alloy body with durable mechanical components designed for long-term use.

Historical Context

The Yashica Mat-124G was released during a transitional period in photography, as SLRs gained popularity and electronic automation began to emerge. Despite this, medium format TLRs remained relevant for portrait, studio, and documentary work due to their quiet operation, lack of mirror slap, and excellent optics. Yashica positioned the Mat-124G as a modern, feature-rich TLR that could compete with German and Japanese high-end models while being more affordable.

Its main competitors included the Rolleiflex 2.8F and 3.5F, the Minolta Autocord, and the Bronica ETR series. While the Rolleiflex offered superior build and lens quality, it came at nearly double the price. The Mat-124G carved a niche by offering 90% of the performance at half the cost. Its TTL metering gave it an edge over the non-metered Autocord IV and earlier Rolleiflex models, appealing to photographers who valued convenience and precision.

Market reception was highly favorable. The Mat-124G was praised in contemporary reviews for its ease of use, accurate metering, and excellent lens performance. It became a staple in photo schools and among working photographers who needed a reliable, high-quality medium format camera without the premium price tag. Production continued until 1986, when declining demand for mechanical TLRs and the rise of autofocus 35mm systems led to its discontinuation.

Collectibility & Value

Today, the Yashica Mat-124G is a sought-after classic among medium format film photographers and collectors. Its combination of functionality, optical quality, and historical significance ensures strong demand in the used market. Well-maintained examples typically sell for $250–$400 USD, with mint-condition units or rare variants commanding higher prices.

When purchasing a Mat-124G, buyers should inspect several key areas: shutter accuracy across all speeds (especially 1/500 and 1 sec), lens condition (absence of haze, fungus, or scratches), and meter functionality. The CdS meter is prone to drift or failure over time, particularly if the camera has been exposed to extreme light or moisture. While the meter can be recalibrated, original mercury batteries (PX625) are no longer available, requiring use of modern substitutes with voltage compensation (e.g., Wein Zinc-Air or hearing aid batteries with -0.15V adjustment).

Common issues include stiff focusing mechanisms (due to dried lubricant), light seals degradation (leading to light leaks), and worn film advance gears. However, the Mat-124G is generally considered repairable, with many parts still available through specialty camera repair shops. Its modular design allows for relatively straightforward servicing compared to more complex TLRs.

Similar Cameras

• Rolleiflex 2.8F – German-built TLR with interchangeable lenses and superior build quality; significantly more expensive.
• Minolta Autocord CDS – Japanese TLR with built-in CDS meter; slightly slower lens (f/3.5) and less refined mechanics.
• Mamiya C330 – Modular TLR with interchangeable lenses and focusing tracks; bulkier but more versatile.
• Bronica ETR – SLR alternative with similar format and metering; interchangeable lenses and focal-plane shutter.
• Pentax 6×7 – Larger format SLR with 6x7 cm negatives; professional-grade but much larger and heavier.

Repair & Maintenance

The Yashica Mat-124G requires two PX625 1.35V mercury batteries for the TTL meter, though modern equivalents such as the Wein Cell MRB625 or alkaline PX625 with exposure compensation (+⅓ stop) can be used. Battery contact corrosion is common in long-stored units and should be cleaned carefully.

Regular maintenance includes CLA (clean, lubricate, adjust) every 5–10 years, especially if the camera is used frequently. Shutter speeds should be tested with a timer or oscilloscope, as aging lubricants can cause inaccuracies. Light seals should be replaced every 10–15 years to prevent light leaks. The film advance mechanism is generally reliable but may require gear inspection if skipping frames.

Due to its mechanical simplicity and widespread production, the Mat-124G is considered one of the most repairable and user-friendly TLRs on the market, making it an excellent choice for both novice film shooters and experienced collectors.
