Modern cameras with through-the-lens metering normally account for it.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\"\u003e\n\u003ch4 itemprop=\"name\"\u003eCan I use the 77mm size on smaller lenses?\u003c\/h4\u003e\n\u003cdiv itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\"\u003e\u003cp itemprop=\"text\"\u003eYes. A step-up ring from the smaller lens thread to 77mm lets you share one larger filter across several lenses, which is often cheaper than buying one filter per lens. Wide-angle lenses may show vignetting with a ring fitted.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Urth","offers":[{"title":"Default Title","offer_id":57664086671735,"sku":"UCPLPRO77","price":115.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1521\/5650\/files\/CPL-Lens-Filter-Pro_1.jpg?v=1793543678","url":"https:\/\/bassandbligh.com\/products\/urth-77mm-circular-polariser-pro","provider":"Bass \u0026 Bligh","version":"1.0","type":"link"}
