f0.7 – Ultrafast Lenses – Legends, budget options, modding, and testing – Epic Episode #13

Video Description

#sponsored In this crazy experiment we push the limits of lens speed by modding a camera to fit a massive Zeiss Biotar f0.73 lens. Along the way, we are going to take you to the dark side of the moon the realm of the legendary Zeiss Planar f0.7 lens and explain how it helped Staley Kubrick to shot Barry Lyndon in candlelight. We are going to go to the basics to explore the possibilities and to expose the limitations of ultrafast lenses. We look into the possibilities that you have to shoot ultrafast yourself, and what budget options there are. Here we test the Kipon Ibelux 40mm f0.85, the SLR Magic 25mm T0.95… and we boost a Vintage Canon FD f1.2 below f1. We compare shooting ultrafast lenses with shooting at high ISO and of course… using both in combination. Special thanks to Lyndon Gaul and the Marmalade for partnering with us.

(It will not be to pretty) You can use this formula to calculate the required flange: Maximum focus distance  = FL x (FL - BF + CF)/(CF - BF) FL  =  focal length of lens BF  =  back focal distance of lens (from rear of lens mount to image plane) CF  =  camera flange distance (look up for your particular camera) Coverage: Here is a list from X-Ray lenses that have been reported to cover Full Frame (3rd person claims – no guarantee).
