Known for its durable build, fast ultrasonic autofocus (USM), and constant f\/4 aperture, it remains an affordable, lightweight workhorse for landscapes, real estate, and event photography.Key Features \u0026amp; SpecificationsFocal Length: 17 - 40 mm (Ultra-wide)Maximum Aperture: Constant f\/4 throughout the zoom rangeLens Construction: 12 elements in 9 groups, featuring Super Ultra-low Dispersion (UD) and aspherical elementsAutofocus: Ring-type USM for fast, silent operation with full-time manual overrideWeather Sealing: Highly resistant to dust and moisture (requires front filter for full environmental sealing)Filter Size: 77 mmWhat to Expect in the BoxWhen unboxing a standard retail package, you should expect to find the following items:The Lens: Canon EF 17-40mm f\/4L USM (with front and rear caps)Lens Hood (EW-83E): A petal-shaped dedicated hood that helps reduce flare and protects the front elementLens Case (LP1319): A soft drawstring pouch for storage and transportDocumentation: User manuals, quick start guide, and warranty informationPros and ConsWhat Photographers Love:Value: It is one of the most affordable and accessible gateways into Canon's premium L-series lens lineup.Build Quality: Features a robust, professional-grade metal mount and weather-sealed construction.Weight: At roughly 500g, it is incredibly lightweight and easy to carry on long hikes or all-day wedding shoots.Things to Keep in Mind:Corner Softness: Like many older ultra-wide lenses, the extreme corners can be a bit soft at 17mm, though sharpness improves significantly when stopped down to f\/8.No Image Stabilization: The lens does not feature optical stabilization (IS), requiring you to rely on a sturdy tripod or higher ISOs in low light.Fixed f\/4 Aperture: While excellent for most daylight situations, it may fall short if you heavily rely on shallow depth-of-field or low-light handheld shooting.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ecanon\u003c\/li\u003e\n\u003cli\u003ecamera lens\u003c\/li\u003e\n\u003cli\u003elens\u003c\/li\u003e\n\u003cli\u003ecanon lens\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cash Generator Bury","offers":[{"title":"Default Title","offer_id":55843484008833,"sku":"BBBY8LKFTSMSZ - EE","price":179.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0296\/1185\/1860\/files\/15b817fb-c120-42e4-a6d1-40fa56ee873b.webp?v=1782465212","url":"https:\/\/cashgenerator.co.uk\/products\/canon-ef-17-40-f-4l-usm-black-camera-lens-1-4-unboxed","provider":"Cash Generator","version":"1.0","type":"link"}
