- Material: High-precision, durable aluminum-magnesium alloy

Key Features
- High-Precision Aluminum-Magnesium Build: Crafted from a robust aluminum-magnesium alloy, ensuring exceptional durability, a stable shape that won’t slip, and a long lifespan for frequent lens swapping.
- Perfect Infinity Focus: Specifically engineered to allow your adapted lenses to reach infinity focus seamlessly. The infinity mark is shifted slightly to the positive side to accommodate temperature-induced focus shifts.
- Secure & Seamless Fit: The connection ring and camera bayonet are designed to tightly and smoothly combine, completely eliminating any loose wiggling or light leaks for professional, sharp results.
- Fully Manual Control: Offers pure manual operation without autofocus or electronic aperture rings, giving you complete, tactile creative control over your vintage or specialty lenses.
- Red Dot Alignment: Features a clear, highly visible red dot indicator that guarantees precise alignment, making the installation and disassembly process fast, comfortable, and safe.
Compatibility & Best Use
- Lens Compatibility: Designed exclusively to adapt classic M42 screw mount SLR lenses to modern digital camera bodies.
- Camera Body Options: Selectable variants support a massive range of systems including Sony Alpha E-Mount (a7, a9, a6000 series), Micro Four Thirds (Olympus, Panasonic), Canon EF/EOS R, Nikon F/Z, and Fujifilm FX.
- Vintage Glass Revival: The perfect, cost-effective accessory for photographers and videographers looking to experiment with character-rich, vintage lenses on state-of-the-art digital sensors.
- Crop Factor Advantage: When adapting a full-frame lens to an APS-C or M4/3 body, it utilizes the lens’s “sweet spot” for excellent edge-to-edge sharpness (Note: this multiplies the focal length by 1.5x to 2.0x depending on the sensor).
Installation Tips
- Camera Settings: Before shooting, you must dive into your camera’s menu and enable the “Release Shutter without Lens” or “Shoot without Lens” setting, as there are no electronic contacts to tell the camera a lens is attached.
- Gentle Mounting: Use the red dot logo to align the adapter with your camera mount and twist until it clicks. Apply skillful, gentle pressure; do not use excessive force during installation.
- Focusing Adjustments: When shooting at infinity, rely on your camera’s digital viewfinder, focus peaking, or magnification tools rather than the physical lens barrel markings to ensure tack-sharp focus.
