This Sirui Astra set brings 50mm, 75mm and 100mm focal lengths together for filmmakers using Nikon Z cameras. It’s a manual-focus cine lens kit, made for video and filmmaking rather than quick autofocus stills. The 1.33X designation and blue-flare look give the set a deliberate visual character for projects where lens rendering is part of the style. Use the different focal lengths to vary framing across a scene while keeping the same creative approach. It suits filmmakers building a lens set around considered focus work, from narrative scenes to music videos and other controlled productions. If you want an autofocus lens for spontaneous still photography, this is a more specialised tool.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eChanging a scene’s framing shouldn’t force you to rethink its whole visual feel; having these three focal lengths in one kit helps keep that transition intentional. I’d point filmmakers towards it for dialogue scenes or music-video setups where manual focus and a recognisable blue flare are part of the plan. T1.8 is useful when you’re working indoors: it lets more light reach the sensor, so you have more room to manage ISO in a dimmer location. For a close interview, open up to T1.8 and focus carefully on the speaker’s eyes. It rewards deliberate focus work, so it’s less suited to fast, unpredictable action.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduct type: Interchangeable lens kit\u003c\/li\u003e\n\u003cli\u003eFocal lengths: 50mm, 75mm and 100mm\u003c\/li\u003e\n\u003cli\u003eMaximum aperture: T1.8\u003c\/li\u003e\n\u003cli\u003eFormat designation: 1.33X\u003c\/li\u003e\n\u003cli\u003eMount: Nikon Z\u003c\/li\u003e\n\u003cli\u003eFocus: Manual\u003c\/li\u003e\n\u003cli\u003eFlare: Blue\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":57564018311508,"sku":"AST-3S-ZB","price":2530.42,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/AST-3S-ZB_01.jpg?v=1791805476","url":"https:\/\/www.htf-store.com\/fr\/products\/sirui-astra-series-50mm-75mm-100mm-t1-8-1-33x-cine-lens-kit-z-mount-blue-flare","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
