Protection for reversed lens

Recommended Posts

Okay, I know these things can be made, but I'm not really good with

glue and stuff, so...

 

Can I buy something that will let me protect the exposed side of a

reversed lens?

 

Something ALREADY MADE.

 

You know...so I dont glue it to my forehead or something.

Okay, well you did say protect... Anyway, you don't mention what you shoot, but if it's Nikon, there is the BR-3 Adapter, which gives you a 52mm threaded front, on which you can use any filter you want... or a lens cap.

For Canon FD there is a "Macro Hood" that protects and also lets you close the diaphragma

 

For Nikon you have the BR-4 and BR-6 for closing the diaphargm with a wire remote cable and then if you need to add a filter or the suport for a ring flash etc the BR-3 already mentioned.

Jorge - I have three BR-3 (two old aluminum color, and one of the newer black ones), a BR-6, and an old E2 (predecessor to the BR-4). I no longer have a BR-4, so that part comes from memory.

 

I recall BR-4 being just like the E2. The E2 is basically an extension tube, 13.2mm thick, with a male Nikon bayonet on one end, and a female bayonet on the other end. It has a screw coupling that you can connect to a cable release so you can stop down a lens.

 

My BR-6 is just like a BR-3, with the functionality of a BR-4 built in.

 

Both BR-3 and BR-6 have a female Nikon F bayonet on one side, so they can attach to the back of any reversed Nikon lens. The other side has a female 52mm filter thread, so you can thread a filter directly into it.

 

That's it for BR-3, just a tube that lets you put a filter on the back of the lens. BR-6 also has a lever that will manually stop down a lens, and an attachment for a cable release to stop down the lens.

 

As a bonus, the BR-6 is 12.6mm thick, which is thinner than the BR-3 alone (at 15.9 for the old style and 16.1 for the new style) let alone the combination of BR-4 and BR-3.

Joseph, I was in doubt because what I saw on some web pages as

and

I have PB-4 and BR-4 (and BR-2 on mail) but I have never seen a BR-6 so I can only use web references

 

Regards
