Twin-Lens Reflex (TLR) Design Explained
The Yashica 124G utilizes a classic Twin-Lens Reflex (TLR) design, a system celebrated for its simplicity and unique shooting experience. Unlike Single-Lens Reflex (SLR) cameras, TLRs employ two separate lenses: a viewing lens and a taking lens. The viewing lens is positioned above the taking lens, projecting an image onto a frosted glass screen for composition.
Crucially, the image seen on the viewing screen isn’t directly from the taking lens; this means parallax error can occur, especially at closer focusing distances. Manuals emphasize understanding this offset and utilizing the bright lines or other focusing aids to ensure accurate framing. The taking lens is the one that actually captures the image onto the film.
This separation of lenses eliminates the viewfinder blackout experienced in SLRs during exposure, allowing continuous observation of the subject. Yashica 124G manuals detail how this system functions, explaining the mechanics of interlens shutter operation and the importance of synchronizing the lenses for optimal image quality. The TLR design offers a slower, more deliberate shooting process, fostering a connection between photographer and subject.
Film Format Compatibility: 120 and 220 Film
The Yashica 124G is remarkably versatile, accepting both 120 and 220 film formats. 120 film is the more commonly available option, providing 12 exposures per roll in the standard configuration. The camera’s design accommodates the different spools required for each film type, ensuring proper film advance and rewind.
220 film, offering 24 exposures, was popular for its increased capacity, reducing the frequency of film changes. However, 220 film is becoming increasingly rare. Yashica 124G manuals provide detailed instructions on correctly loading and winding both film types, emphasizing the importance of proper tension and alignment.
Adapters are available to use 120 film backs in cameras designed for 220, but using a dummy spool is crucial to take up the extra space. Understanding the differences in spool sizes and film backing paper is vital for successful operation. Refer to the instruction booklet for specific guidance on selecting the correct settings and ensuring compatibility.
