Canon F1 and F1n shutter capping

colin wells · Jun 26, 2017

Is this a common problem on early F1s .Recently i purchased another early F1 (1972) in nice condition i fired off a test roll and it came back with a shadow on the side of the pic . This is the second F1 that this has happened (my first was a F1n 1978 ) .It is an easy fix so i wasn't bothered but i was just wondering if it is common as in the FTB .

I wasn't aware this was a common fault in the FTb Colin and I have had mine about forty years. I have two F1n's also I have had less than a year that has never had this problem either.

I repair Canon FTB s so by the time they get to me i dont see the most pristine models lol .Apart from the capping on the F1s that i have i think they are a great camera and just wondered if it was common as that's two out of two with the problem (now fixed )

Over the past few years, I’ve picked up a Nikon F2 (a beautiful camera), a Pentax Spotmatic, and a Olympus OM-1. All three show capping when I shoot at fast speeds. Shutter capping is not all that unusual in cameras that are 40+ years old, no matter who makes it.

This has me curious as I have not begun taking cameras apart yet although I have fixed a few "shutter locked up" problems.
My casual observation is that all mechanical horizontal travel shutter mechanisms are basically same for all cameras equipped with such and that the problem of delayed travel is due to contaminants and old lubricants. If this is the case, then all cameras with this mechanism will fail in due time - use and environmental conditions will affect this, unless serviced at some regular interval. However, if the cause of the failure you are experiencing is due to specific parts for these cameras then it could be isolated to just those cameras.

Hi Les i think the two F1s that i have had been left for a long period (years)cocked as on the outside they a both in very good condition .As Mackinaw say these cameras are getting on now but in most cases capping is an easy fix .

I ran into a problem some years ago when I was on vacation. I was shooting with an F-1 and had a 300/5.6 on the camera, pointed at the top of the Cape May lighthouse. To keep things steady shot at 1/2000. The problem on one side of the frame was due to a shutter brake malfunction. It was repaired and has worked properly since then. I can't say that I shoot at 1/2000 very often. If I want that shutter speed to be as accurate as possible I will use a Nikon F3 or a Nikon N90S.
