Industar 50-2 50 mm f/ 3.5 Lens Manuale Di Servizio

 
 

These are perhaps one of the easiest of the FSU lenses 
to service and re-lube. The procedure for the Industar 
26M and the Industar 61 are almost the same. I will 
note any differences at the end 
 
Begin by removing the light baffle (if fitted) from the 
back of the lens. This should just pop out 
 
 
 
 
 
 
 
 
 
 
 
 
 
Remove the 3 screws around the focus ring and remove 
the ring. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Either slacken off or remove this screw. It is the one 
directly opposite the depth of field scale.
