It provides the connection between the named lens and the Swift magnetic filter system. That makes it a focused accessory for Canon 17mm F\/4L owners who already use, or plan to use, Swift magnetic filters. Its appeal is in matching the ring to this specific lens rather than shopping for a general-purpose filter accessory and hoping it suits. Use it as the lens-side part of your filter setup, then choose the Swift magnetic filters you want to use for the scene. It’s a straightforward piece of kit with a clear role: linking this Canon lens to H\u0026amp;Y’s Swift magnetic system.\u003c\/p\u003e\n\n\u003ch3\u003eA ring for the named lens\u003c\/h3\u003e\n\u003cp\u003eThe product name specifies both the H\u0026amp;Y Swift system and the Canon 17mm F\/4L. That makes the intended pairing easy to identify when you’re building a filter setup around this lens. It’s relevant if you want to keep your filter choices within the Swift magnetic system, rather than treating this as a general adapter ring for several lenses. The ring itself is the connection piece; your filter choice depends on the image you want to make.\u003c\/p\u003e\n\n\u003cdiv class=\"specialist-note\"\u003e\n  \u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n  \u003cp\u003eThis ring gives the Canon 17mm F\/4L a Swift magnetic filter connection, rather than leaving you to find a filter that fits the lens directly. If you use this lens for broad landscapes, you can build your setup around Swift magnetic filters and choose the filter for the light and scene. The 17mm focal length suits wide compositions, so take care with what enters the edges of the frame. For an indoor scene, the f\/4 designation gives you a practical aperture reference when setting exposure; the ring doesn’t change the lens’s aperture. The key point is the specific pairing: this is the ring to consider for the Canon 17mm F\/4L, not a general ring for every lens.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eProduct: H\u0026amp;Y Swift Magnetic Lens Adapter Ring\u003c\/li\u003e\n  \u003cli\u003eSpecified lens: Canon 17mm F\/4L\u003c\/li\u003e\n  \u003cli\u003eLens designation: 17mm F\/4L\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"H\u0026Y","offers":[{"title":"Default Title","offer_id":57492047724884,"sku":"HY-RM-ARC17","price":25.81,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/HY-RM-ARC17_01.jpg?v=1791544367","url":"https:\/\/www.htf-store.com\/it\/products\/h-y-swift-magnetic-lens-adapter-ring-for-canon-17mm-f-4l","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
