It covers a full-frame sensor, making it suitable for cameras such as Sony Alpha full-frame bodies as well as APS-C Sony E-Mount cameras.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor cinema use, the aperture mechanism has been de-clicked, allowing smooth and continuous iris adjustments during filming instead of fixed photographic aperture stops. A follow-focus gear is installed on the focusing ring, providing more precise manual focusing and compatibility with professional follow-focus systems.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe lens has been fully cleaned, mechanically adjusted and re-lubricated before sale.

Its 50mm focal length gives a natural perspective on full-frame cameras, while the fast F1.4 aperture allows strong subject separation, shallow depth of field and effective low-light shooting.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e⚙️ Technical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eLens Mount - Sony E-mount\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFocal Length - 50mm\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMaximum Aperture - F1.4\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMinimum Aperture - F22\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eAperture Blades - 8\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMinimum Focus Distance - 0.45m\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFilter Thread - 49mm\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFocus Type: Manual\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSerial Number - 6616881\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003e🎬 Why Choose This Lens?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThe Pentax-M 50mm F1.4 is a strong choice for filmmakers who want a genuine vintage full-frame look without giving up practical production handling. At F1.4 it can produce shallow depth of field, gentle background separation and a distinctly vintage rendering that works especially well for portraits, narrative filmmaking, music videos, interviews and stylized commercial work. The de-clicked aperture makes exposure transitions smoother during a take, while the geared focusing ring improves compatibility with follow-focus systems. Unlike a modern clinical prime, this lens retains the personality of an original late-1970s Pentax optic while being prepared for modern Sony E-Mount cinema and mirrorless cameras.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e📦 This Offer Includes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003e✔ Asahi SMC Pentax-M 50mm F1.4 Cine-Mod Lens\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e✔ Sony E-Mount Adaptation\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e✔ De-clicked Aperture Modification\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e✔ Follow-Focus Gear on Focusing Ring\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e✔ Lens Hood \/ 72mm Front Setup\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e✔ Front Lens Cap\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e✔ Rear Lens Cap\u003c\/strong\u003e\u003c\/p\u003e","brand":"Asahi","offers":[{"title":"Sony E-mount","offer_id":66841792708723,"sku":"880007322672","price":224.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0566\/6429\/3491\/files\/asahi-smc-pentax-m-50mm-f14-cine-mod-vintage-portrait-prime-sony-e-mount-terphoto-store-8042419.png?v=1791736694","url":"https:\/\/terphoto.store\/products\/asahi-smc-pentax-m-50mm-f1-4-cine-mod-vintage-portrait-prime-sony-e-mount","provider":"TerPhoto Store","version":"1.0","type":"link"}
