Its clear distinction is right in the name: this is an extension barrel, not a complete lens or camera. It suits someone who already knows an extension barrel is needed in their setup and wants to identify the correct part by its model number. The barrel’s purpose is to add extension within an optical assembly; the exact role it plays depends on the setup it’s being used in. Metal construction gives it a solid, practical place in that assembly. If you’re searching for a BORG extension barrel, the 4604 name makes this product easier to identify than a generic component description. It’s best considered as one part of a larger optical arrangement, rather than as a standalone imaging tool.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003e4604 is the model number; in practice, that gives you a precise way to identify this particular extension barrel when sourcing a component for your BORG setup. I’d focus on its role in the assembly: it’s an extension barrel, so it belongs where an extension is needed, rather than being a lens or camera in its own right. The metal construction makes it a tangible structural component within that arrangement. It suits BORG users who are putting together an optical setup and already know they need this specific kind of part. My advice is to use the 4604 designation when discussing or selecting the component, so the part you’re considering stays clearly identified.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduct type: Extension barrel\u003c\/li\u003e\n\u003cli\u003eMaterial: Metal\u003c\/li\u003e\n\u003cli\u003eModel number: 4604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BORG","offers":[{"title":"Default Title","offer_id":57563633025364,"sku":"BG-4604","price":28.62,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/BG-4604_01.jpg?v=1791804884","url":"https:\/\/www.htf-store.com\/it\/products\/borg-4604-metal-extension-barrel","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
