Camera question re lenses

[Old Sparky]

I hav for many years owned a Zorki 4K, with 35, 50, & Jupiter 11, 135mm lenses and the accessory viewfinder, so have been reading the information pages* with interest. Haven't used the camera for several years, but have never had to carry out any adjustments to it. I've no idea whether the lenses would be compatible with 625 line cameras, though! * I googled FED Cameras, and found, among other things, full details of how to service & adjust these cameras, but don't remember the link to the site in question!
