Period information from the late 1970s documents the Auto-Flex 50mm F2.8 as a four-element lens, and independent lens references describe its optical formula as being based on the classic Tessar-type design. This simple optical construction is appreciated by vintage-lens shooters for its traditional rendering, good central definition and distinctly non-modern character.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis example has been fully cleaned, adjusted and re-lubricated, then professionally adapted and calibrated for Canon EF mount. The aperture has been de-clicked, allowing smooth continuous iris adjustment during video recording rather than the stepped movement of the original photographic aperture mechanism.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA follow-focus gear is installed on the focusing ring, allowing integration with standard cinema follow-focus systems for controlled manual focus pulls. The supplied cine hood has an 80mm outside diameter, making the lens more convenient to incorporate into a cinema-oriented rig.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe lens covers a full-frame sensor, making its 50mm focal length a true normal\/standard field of view on full-frame Canon EF cameras and compatible cinema bodies. It is particularly useful for narrative filmmaking, interviews, portraits, music videos, commercial work and projects where a more organic vintage rendering is preferred over the highly corrected appearance of modern lenses.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe glass is in good vintage condition. There is very minor age-related wear on the glass, typical for vintage optics of this period. According to inspection, these minor signs do not affect the final image. The exterior shows normal vintage signs of use visible in the listing photographs. The lens has been serviced and prepared for practical shooting rather than being sold merely as an untouched collectible.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe photographs show the actual lens offered for sale.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003e⚙️ \u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eLens Mount - Canon EF\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 - F2.8\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMinimum Aperture - F16\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eAperture Blades - 6\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMinimum Focusing Distance - 0.5m\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFilter Size - 52mm\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 - Various\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 Auto Flex 50mm F2.8 offers an affordable route into genuine vintage full-frame optics while adding practical features needed on a modern cinema rig. Instead of digitally imitating a vintage look, you are shooting through period Japanese glass with a classic Tessar-style optical concept. The de-clicked iris makes exposure transitions smoother, while the geared focus ring provides more precise follow-focus operation. On full frame, 50mm is extremely versatile for portraits, interviews, medium shots, narrative coverage and detail work. TerPhoto’s cleaning, re-lubrication, adjustment and Canon EF conversion turn this compact vintage photographic prime into a practical character lens ready for contemporary filmmaking.\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✔ Auto Flex 50mm F2.8 Vintage Cine-Mod Lens\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e✔ Canon EF 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✔ 80mm OD Cine Lens Hood\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":"Auto Flex","offers":[{"title":"Canon EF (EOS)","offer_id":45390441087091,"sku":"178433238230","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0566\/6429\/3491\/files\/6a8a980a8d7afcc1f4e08645.png?v=1787468240","url":"https:\/\/terphoto.store\/products\/auto-flex-50mm-f2-8-vintage-cine-mod-prime-portrait-lens-canon-ef","provider":"TerPhoto Store","version":"1.0","type":"link"}
