About the Product

The tactile clicking sensation helps you make precise changes without taking your eye away from the scene.

Faqs:
What is the main advantage of renting the Control Ring Adapter over the standard EF-EOS R adapter?
The main advantage is the extra, customizable control ring. This ring allows you to quickly change key shooting settings like aperture, shutter speed, or ISO without navigating camera menus. This is a massive benefit for tourists needing to adjust settings rapidly while capturing dynamic scenes in Japan.
Will my old EF lenses maintain their autofocus speed and image quality when used with this adapter?
Yes, the adapter is designed to maintain the full functionality of your EF and EF-S lenses, including their native autofocus speed and image stabilization performance. The adapter contains no glass elements, so it does not degrade the optical quality of the attached lens.
Can I use my smaller APS-C (crop sensor) EF-S lenses with the EOS R full-frame cameras using this adapter?
Yes, EF-S lenses can be attached using this adapter. When an EF-S lens is detected, the EOS R camera automatically switches into its crop mode, utilizing only the central portion of the sensor. While this reduces the resolution, it ensures compatibility and proper function of your EF-S lenses.
Are there any Canon lenses that are NOT compatible with this mount adapter?
Yes, the adapter is not compatible with Canon EF-M lenses (designed for the EOS M series mirrorless cameras) or EF Cinema lenses (CN-E). It is designed exclusively for the standard Canon EF and EF-S lens lineups used with DSLR cameras.
Where is the best place to set the Control Ring for general travel photography in Japan?
Many traveling photographers find assigning the Control Ring to Exposure Compensation is the most practical choice. This allows for quick, intuitive fine-tuning of brightness when moving between bright outdoor scenes and dark interiors of shrines or museums, ensuring consistent exposure without fiddling with the camera body.
