It’s an interchangeable cine lens kit for Sony E mount cameras, designed for video and filmmaking. The three focal lengths let you move from a more open composition to tighter framing by changing lenses, rather than relying on a zoom. That makes the set a practical fit for planned scenes, interviews and narrative work where you want deliberate framing choices. Each lens is marked T1.8, giving you a bright aperture to work with when light is limited. Focus is manual, so the kit suits operators who want to control focus themselves and can take the time to set and pull focus. It’s a focused set for video makers who value repeatable, intentional shots over autofocus convenience.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eIs the Astra 50\/75\/100mm kit for filmmakers who want to control every focus change? Yes—it’s a manual-focus set, so you’ll pull focus yourself rather than rely on autofocus. I’d suggest the 50mm for a medium dialogue shot, then the 75mm or 100mm when you want a tighter view without changing the scene. The T1.8 aperture gives you more room to work in a dim interior; keep an eye on focus, especially at the tighter focal lengths. This kit suits planned video work and operators comfortable marking or rehearsing focus pulls. The trade-off is clear: it asks for hands-on focus, not quick automatic tracking.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduct type: Interchangeable lens\u003c\/li\u003e\n\u003cli\u003eLens type: Lens kit\u003c\/li\u003e\n\u003cli\u003eFocal lengths: 50mm, 75mm and 100mm\u003c\/li\u003e\n\u003cli\u003eAperture: T1.8\u003c\/li\u003e\n\u003cli\u003eDesignation: 1.33X\u003c\/li\u003e\n\u003cli\u003eMount: Sony E\u003c\/li\u003e\n\u003cli\u003eFocus: Manual focus\u003c\/li\u003e\n\u003cli\u003eIntended use: Video and filmmaking\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sirui","offers":[{"title":"Default Title","offer_id":57492203602260,"sku":"AST-3S-EN","price":2530.42,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/AST-3S-EN_01.jpg?v=1791544628","url":"https:\/\/www.htf-store.com\/fr\/products\/sirui-astra-series-50mm-75mm-100mm-t1-8-1-33x-cine-lens-kit-e-mount","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
