The single biggest reason to buy is the built-in drop-in filters: a variable ND (ND3-ND500), a circular polarizer and a clear filter that slot into the adapter without adding glass in front of the lens, so users retain the original lens optics while gaining quick access to ND and CPL control. The adapter also promises to preserve autofocus and image stabilization, making it a useful bridge for EF glass on RF-mount cameras.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eDrop-in filters:\u003c\/strong\u003e Includes a variable ND (ND3-ND500), a circular polarizer and a clear filter so you can control exposure and reflections without attaching front filters to each lens.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eFull electronic compatibility:\u003c\/strong\u003e Retains autofocus and image stabilization functions so lenses behave as expected on compatible Canon EOS R bodies.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eNo optical elements in path:\u003c\/strong\u003e The adapter contains no glass components, helping preserve the original optical quality of mounted EF or EF-S lenses.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eSolid metal construction:\u003c\/strong\u003e A high quality metal body with a non-glare internal finish reduces reflections and feels durable for regular use.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eRemovable tripod mount:\u003c\/strong\u003e Includes a tripod foot with a 1\/4-20 screw to stabilize heavier lens combinations on a tripod.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eComplete kit:\u003c\/strong\u003e Supplied with front and rear caps and a storage pouch for the adapter and drop-in filters to keep everything protected when not in use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis adapter is aimed at photographers who already own Canon EF or EF-S lenses and are switching to or using Canon EOS R bodies such as the R100, R50, R7, R8, R10, R5 series and R6 models.
