Kaleinar-5 extension hood

[Gurdie]

Kaleinar-5 100/2.8 lens, as well as Nikkor 135/2.8 Ai-S, have built in hoods, unfortunately not deep enough to be very effective.

Today I was playing with a short hood with 58 mm threads I got in a package of hoods from member Alex, and I found out, that this hoods fit
to Kaleinar´s and Nikkor´s built in hoods, and can be used as an extension hood. The Kaleinar´s built-in hood is plastic, and the metal extension can be fitted quite tightly. The Nikkor hood is metal, and is without threads, but anyway the extension can stand light knocks without dropping off. The hood is 25 mm deep, and, as a bonus, accepts a 62 mm lens cap.




I cannot see any vignetting in the pictures with the extension.

Next I´ll try to find same kind of solution to my Nikkor 180/2.8 Ai-S lens, which have same kind of (too short) built-in hood.

I just use 52mm telephoto hoods on both of these lenses. No need to affix them to the built-in hood, just using the filter threads.
