Cleaning the 1000mm Reflex-Nikkor
« on: May 30, 2016, 02:49:38 »
Have had my 1000mm Reflex-Nikkor for a number of years.  I have also used my late model 2X telextender on it quite successfully.  But I have noticed that I have some dust which seems to get in easily with this design.

Is there a simple (or relatively simple) way to get inside to clean elements, or the mirrors?  Which lenses or mirrors are the more influential upon imagery quality if dusty?

TIA,

Dan

Just remember, unlike the coatings on lenses, the aluminum coating on the mirrors is extremely fragile and easily scratched. If I were you, I would limit cleaning of the mirror surfaces to nothing more than blown air, or possibly a very soft brush if absolutely necessary.

Good Advice!

too give you an idea ::)

a different lens, but construction should be the same. :o :o :o

have you tried the vacuum cleaner approach?

I have not tried any methods yet.  I can see how the design can literally suck dust laden air into the mechanism.  I think I'll have to take the front mirror off to gain access to blow off the surfaces, o to vacuum out the internal workings.

Thanks

Hello. I have just received a very nice condition Nikkor 1000mm f/11 lens. It came without the focusing handle. 

Does anyone know what thread is used for the focusing handle?  It is clearly less than the 1/4" tripod mount, but i don't have any suitable small bolts to do trial and error with.

Thanks, Ross
