What Lens Hood to Use for Industar or Jupiter Lenses?

For Jupiter-3 and -8, as well as Industar -26M and -61 lenses, you’d need the slip-on 42 mm diameter hoods.

Two types of Soviet-made hoods for these lenses can be found: round and rectangular. 

The rectangular version can only be used for certain types of Jupiter and Industar lenses.  These would be the Jupiter made until the 1960s, and were usually with white aluminium barrels.  These lenses did not have rotating fronts.   Later Jupiter (and Industar?) lenses made from the 1970s onwards  would have rotating fronts.  A rectangular hood would rotate as the lens is focused and would result in various degrees of vignetting.

The round version is for the later Jupiter lenses. Usually these are the black Jupiters.  They should also be the type used for Jupiter lenses on Kiev cameras.  A round hood will always have the same orientation when the lens rotates during focusing so vignetting can never be a problem.

The hoods (diameter 36mm) for collapsible Industar will also fit Elmar lenses.  They are deep enough even for use with Elmar 9 cm lenses.  On a 50mm, they can be too long. 

This hood can easily be DIY’ed with a piece of blackened cardboard tube.  3 cm deep and 36mm wide, no tapering necessary.  This would be good enough in cutting stray light.

These hoods can cause viewfinder blockage.  However an accessory finder can be used.  The finder in this case will be high enough to clear the hood.  With long lenses, extra finders are used anyway.
