{"product_id":"tribe7-blackwing7-s-tuned-137mm","title":"Tribe7 Blackwing7 137mm T1.9 S-Tuned PL Mount Large Format Cinema Prime Lens, 14-Blade Iris, Tunable Near-Neutral Character, Controlled Flare","description":"\u003cp\u003eS Straight is the most neutral of the three Blackwing7 tunings. Its profile references optical designs from the first half of the 20th century, such as the 1950 Wray Unilite 50mm f\/2. Multi-layer coated elements keep the resonant flares of the T and X variants in check, lift central sharpness a little, and hold a smooth roll-off of contrast across the frame. It suits commercial and mixed workflows where a consistent, near-neutral starting point matters.\u003c\/p\u003e\u003cp\u003eBlackwing7 is a family of tunable large format prime lenses from Tribe7, the company co-founded by Academy Award nominated cinematographer Bradford Young, ASC, and lens designer Neil Fanthom. Rather than chasing clinical perfection, Blackwing7 treats optical character as a creative control. Controlled distortion is introduced during manufacture, letting sharpness, contrast, roll-off, spherical aberration, field curvature, edge halation, and flare be shaped to taste. The design language draws on primes built between the 1930s and 1960s, but these are new optical designs, not rehoused vintage glass. Every Blackwing7 is hand-built and individually tuned to order.\u003c\/p\u003e\u003cp\u003eAcross the range the lenses share a 14 blade non-linear iris for rounded bokeh, a 114mm front outside diameter for fast matte box and accessory swaps, industry standard 0.8 MOD focus and iris gears, and an ARRI PL mount that pairs with full frame and large format cinema cameras such as the ARRI ALEXA Mini LF and ALEXA 65, Sony VENICE, and RED V-RAPTOR.\u003c\/p\u003e\u003cp\u003eEach Blackwing7 lens is hand-built and tuned to order, so production lead times apply. Tuning choice can typically be adjusted up to eight weeks before delivery.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFocal length: 137mm\u003c\/li\u003e\n\u003cli\u003eTuning: S Straight (S-Tuned)\u003c\/li\u003e\n\u003cli\u003eLens mount: ARRI PL\u003c\/li\u003e\n\u003cli\u003eFormat coverage: Large format and full frame\u003c\/li\u003e\n\u003cli\u003eImage circle (max illumination): 62 mm\u003c\/li\u003e\n\u003cli\u003eMaximum aperture: T1.9 (T1.8 on 77mm and 107mm depending on production generation)\u003c\/li\u003e\n\u003cli\u003eMinimum aperture: T22\u003c\/li\u003e\n\u003cli\u003eIris: 14 blade, non-linear\u003c\/li\u003e\n\u003cli\u003eClose focus: 32.0 in \/ 81.3 cm\u003c\/li\u003e\n\u003cli\u003eFront diameter: 114 mm outside diameter\u003c\/li\u003e\n\u003cli\u003eFocus rotation: 270 degrees\u003c\/li\u003e\n\u003cli\u003eFocus and iris gears: 0.8 MOD (module)\u003c\/li\u003e\n\u003cli\u003eFocus scale: windowed, marked in feet (meters on request)\u003c\/li\u003e\n\u003cli\u003eTransmission waveband: 420 to 680 nm\u003c\/li\u003e\n\u003cli\u003eColor and tonality: matched across the range\u003c\/li\u003e\n\u003cli\u003eWeight: 3.2 lb \/ 1.5 kg\u003c\/li\u003e\n\u003cli\u003eOperating temperature: -20 to +45 C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BLACKWING 7","offers":[{"title":"Default Title","offer_id":52427675304210,"sku":"BW7-S-Tuned-Single-137mm-Lens-PL-mount","price":14169.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0379\/2529\/0029\/files\/TRIBE7-4_d5c45acf-6466-4c17-9b31-6d134b988723.jpg?v=1782757221","url":"https:\/\/sixstarpsl.com\/products\/tribe7-blackwing7-s-tuned-137mm","provider":"SixStarPSL","version":"1.0","type":"link"}
