Robot camera lens hood

There are two types of genuine Robot lens hood one both silver color, one screw in with 37.80 thread

the other snap in type .

 

The snap in Robot lens hood fits all Robot lens and Robot filters.

 

The screw in Robot lens hood only fits screw in Robot filter, it does not fits Robot snap in filters

 

I also bought a black 38mm screw mount lens hood for Robot Royal on ebay, this is a piece of junk. It does not fit Robot camera

lens, too small. Measured with Mastercraft caliper, this lens hood thread is only 37.75mm, a 0.25 mm error is too much

 

than I bought a silver color 38mm screw in lens hood for Robot, it is also 37.75 thread, not 38mm thread

 

Beware of third party lens hood for Robot fron CN, they do not fit any Robot lens nor filter

 

Genuine Robot snap in filter fits all lenses

 

Genuine Robot screw in filter only fits selected Robot lens /filters

My Robot Star 50 has a 38mm f:2.8 lens with SK number that puts it at 1979/1980 manufacture date. It is fairly deeply set in its mount so does not need a hood as far as I can tell.

John, you are right,

 

The robot Star 50 Xenar 1:2.8 38mm lens needs no lens hood
