The Sandmarc 48mm Tetraprism lens is a telephoto that you can add to an iPhone tele (5x, 4x or 8x depending on the model) that will double that focal length. In this video I test it out and compare it to ReeFlex and Shiftcam. (Note: I did not compare any Shiftcam footage in this video as my lens from them needs to be replaced) 🎥 Check out the LUT Packs and Film Grain: https://geni.us/iPhoneLUTs ▶︎FEATURED GEAR: Sandmarc Lens https://geni.us/ShopSandmarc ReeFlex Lens https://geni.us/ReeFlexProLenses Shiftcam Lens https://geni.us/Shiftcam240mm Beastgrip Pro https://geni.us/QdB1 Beast Handle https://geni.us/EEylD Quick release https://geni.us/ykJnW (Amazon) SmallRig tripod https://geni.us/EXEyqaK (Amazon) LEARN MOBILE FILMMAKING! ▶︎ Complete Guide to the Blackmagic App https://geni.us/BlackmagicCamCourse ▶︎ Smartphone Cinematography 101: https://geni.us/SmartCine101 ▶︎ How To Make a Short Film Guide https://geni.us/DIYShortFilmGuide ▶︎ Complete Guide to Smartphone Audio: https://geni.us/SmartAudio101 🎬 My movie "Casey Makes a Mixtape" is NOW on Digital and Blu-ray!👇🏻 http://www.caseymakesamixtape.com ▶︎ FAVORITE Apps & Gear: Blackmagic Cam (camera app) https://apple.co/3NQ4doM LumaFusion (editing app) on iOS: https://apple.co/2zL3sJW Smartphone Gimbal https://geni.us/BaAGD Hybrid Gimbal https://geni.us/NmUCxt Universal Camera Cage/Grip https://geni.us/QdB1 Tripod Mount https://geni.us/v3pto Mini Tripod https://geni.us/DbUyG Battery Pack https://geni.us/weBviG Small LED Light https://geni.us/Baj8XIB Camera Mount Mic https://geni.us/df8Tcb8 Moment Lenses https://geni.us/ShopMomentLenses ▶︎ MUSIC We Use (get 2 months free): https://goo.gl/RcMx4N ▶︎ EDITED with Adobe Premiere Pro https://geni.us/E1XrVk Need more smartphone filmmaking gear ideas? https://www.iphoneographers.tv/apps-gear ▶︎ JOIN this channel to support it and access cool perks: https://www.youtube.com/channel/UC8Zxb0nqCebD3AZ4S6SmC-g/join ▶︎ CONNECT: http://www.twitter.com/ifilmmakers http://www.instagram.com/watchifilmmakers http://www.facebook.com/iphoneographers ▶︎ SUBSCRIBE & listen to my PODCAST http://bit.ly/AlmostProPodcast If you’re new to the channel it's all about taking mobile & DIY filmmaking to the next level.
