(2 edits in all) | Thanks for the tip: just figured out how to do it on the 5D4: bit more complicated as you have to disable anti-flicker first. But in manual, can set it so it's over 30 secs. While my manual method needs disclaimers of needing to be careful, it does let me see the action of the AF mirror assembly underneath Canon 5D mk IV

joeseph "smells like turd"  More info | Dec 19, 2019 02:42 | #18 Picture of my 1D2 broken shutter:  Image hosted by forum (1016154) © joeseph [SHARE LINK] THIS IS A LOW QUALITY PREVIEW. Please log in to see the good quality stuff. the leaves are like venetian blinds, but are only held onto the mechanism that goes up & down by two small rivets at one end... some fairly old canon camera stuff, canon lenses, Manfrotto "thingy", and an M5, also an M6 that has had a 720nm filter bolted onto the sensor:

Dec 19, 2019 08:20 | #21 I like the idea of using the mirror lockup and a very long exposure (>3 sec) while taking a video of the shutter opening and closing. You can advance the frames manually and inspect them. The normal video is too slow to catch the curtain motion, but with a bit of luck you can catch the curtain mid frame. If you have access to a video camera with slo-mo or super slo-motion you can improve your chances considerably... Gerry
