NightSky M42 T-Ring for Canon EOS EF/EF-S Cameras

Description

NightSky T-Ring M42 Canon EOS Adapter for Canon EF/EF-S

The NightSky T-Ring M42 Canon EOS Adapter is designed to connect Canon EOS EF and EF-S DSLR cameras to telescopes, microscopes, spotting scopes, and other optical instruments equipped with a standard T2 (M42 × 0.75) thread. A T-ring replaces the camera lens and provides a secure interface between the camera body and a compatible T-adapter, allowing the optical instrument to function as the camera's lens. Made from precision-machined metal, this adapter ensures a stable, accurate connection for astrophotography, photomicrography, and other imaging applications.

• Compatible with Canon EOS DSLR cameras featuring EF and EF-S lens mounts.
• Equipped with a standard T2 (M42 × 0.75) thread for connecting cameras to telescopes, microscopes, and other optical accessories.
• Enables prime-focus photography by replacing the camera lens with a telescope or microscope.
• Precision-machined metal construction for a secure, stable, and durable connection.
• Black anodized finish minimizes internal reflections and enhances image quality.
• Easy to install and remove with a precise bayonet mount that locks securely onto the camera body.
• Maintains accurate alignment between the camera and optical system for reliable imaging.
• Lightweight and compact design, making it easy to carry and store.
• Compatible with all standard T2 (M42 × 0.75) adapters and accessories.
• Ideal for astrophotography, lunar and planetary imaging, terrestrial photography through spotting scopes, and photomicrography.

Aditional Information:

Canon has more than one lens mount, so you need to know which one your T-ring is designed for.

1. Canon EF / EF-S Mount (DSLR)

• Canon EOS 90D
• Canon EOS 80D
• Canon EOS 70D
• Canon EOS 7D Mark II
• Canon EOS 5D series
• Canon EOS 6D series
• Canon EOS Rebel / Kiss / xxxD / xxxxD series

A T-ring for these cameras is usually called:

Canon EOS T-Ring or Canon EF/EF-S T-Ring

2. Canon RF Mount (Mirrorless)

Compatible cameras include:

• Canon EOS R
• Canon EOS RP
• Canon EOS R5
• Canon EOS R6
• Canon EOS R7
• Canon EOS R8
• Canon EOS R10
• Canon EOS R50

These cameras require a different T-ring.

3. Canon EF-M Mount (Mirrorless)

Compatible cameras include:

• Canon EOS M50
• Canon EOS M6 Mark II
• Canon EOS M200
• Canon EOS M100

Canon has discontinued the EF-M system in favor of RF, so EF-M T-rings are becoming less common.
