RX5 Diopter Issue

Recommended Posts

Hi -

I've been trying to set the diopter on a new-to-me RX5, and no matter what I do I cannot bring the grain on the prism into focus in the viewfinder. I've turned the adjustment ring as far as it will go in either direction and there is just no change in the image. 

Am I missing a step here? Does the diopter need to be serviced? Any help is greatly appreciated. 

 

Thanks!

Does the eyepiece section telescope in and out when you adjust the ring? Make sure you’re turning the front ring with the mark, not the knurled rear ring which just locks the adjustment in place. Sometimes the adjustment ring can be very stiff or cracked and hard to adjust. Is there a screw in it or is it missing?

Got a photo?

I had this problem as well with my RX4. Someone had jammed the eyepiece in too far, which made it stick AND cracked the adjuster ring with the screw in it. I had to completely dismantle the eyepiece assembly and clean it (as well as the reflex finder) to get the ground glass into focus. I'll be getting that piece replaced when it goes in for service soon. Good luck.

-- this was the issue. The eyepiece is totally disconnected from the adjustment ring, but it does telescope in and out, so I was able to adjust the eyepiece manually and then lock it into place. 

Thanks for your help!
