Lens Adapter Pixco: Canon EOS (EF/EF-S) to T2 mount

Mechanical lens adapter Pixco: Canon EOS (EF/EF-S) to T2 mount allows mounting T2 (M42x0.75) threaded lenses and accessories on Canon EOS cameras with EF or EF-S mounts. This passive adapter provides a secure physical connection between the camera body and manual T2/M42 optics without electronic contacts, preserving manual aperture and focus control. It is designed for photographers and videographers who need to use vintage or specialty threaded lenses on modern Canon EOS bodies while retaining full mechanical control over the lens.

Advantages

The Pixco adapter delivers a rigid mechanical interface with accurate flange distance for reliable focus to infinity on compatible combinations. Its passive construction means there are no electrical contacts or electronic communication, eliminating software compatibility issues and ensuring consistent manual operation. The adapter's construction uses metal components for durability and repeatable mounting, and it maintains the optical characteristics of the attached T2/M42 lens without adding optical elements.

Suitable for

• Attaching vintage M42/T2 prime lenses to Canon EOS EF/EF-S bodies
• Using manual cine lenses and threaded adapters for video on Canon EOS cameras
• Macro photography with extension tubes or focusing helicoids in T2 mount
• Mounting optical accessories such as T2-compatible adapters, bellows, or teleconverters that use a T2 thread

Key specifications

• Mount conversion: Canon EOS EF/EF-S (camera side) to T2 / M42x0.75 (lens side)
• Type: mechanical, passive adapter (no electronic contacts)
• Material: metal construction for mount rings and body
• Optical elements: none (maintains original lens optics)
• Compatibility: manual focus and manual aperture lenses with T2/M42 thread
• Function: provides physical connection and correct flange focal distance for compatible lens-camera pairs

How to use

Align the red or white index marks on the adapter and the camera mount, then insert and rotate the adapter until it locks into the Canon EF/EF-S bayonet. Screw the T2-threaded lens or accessory into the adapter's M42x0.75 thread until secure. Confirm mechanical engagement and check that the lens can focus across its range, including infinity. Because this is a passive adapter, set focus and aperture directly on the lens; the camera will not control these functions electronically. Remove the adapter by pressing the camera's lens release and rotating the adapter off the mount, then unscrew the lens from the T2 thread if required.

Usage recommendations

Use this adapter with manual lenses on a stable support or tripod when precision focusing is required. Verify compatibility and test focus range with your specific lens to ensure infinity focus. Avoid forcing threaded attachments and keep mounting surfaces clean to prevent wear. For exposure metering, use camera modes that support manual lenses or enable appropriate metering and focus aids on the camera body.
