Having recently purchased a Samsung NX100 with the 20-50 lens and fallen in love with it, one thing that is a downer for me is the lack of a viewfinder. I do not want to buy the offered optional EVF from Samsung at this time, mainly I am put off by the price, further, it appears to be powered by the camera battery.
I remembered having placed a flip up finder from an old press camera on a SONY MVC FD73 to help me in quick shots as the camera was a bit hard to get quickly on target. The so called Russian made universal turret came to mind, then the Argus turret. Best of the two would be the Argus since I have two of them. Both were in a box with the Argus bricks. I took the one in worse shape as far as the optics are concerned.
First to be removed were the three ‘lenses’ on the rotating front – they simply unscrew with a little help from a rubber tipped needlenose.. All three have dirt and what looks like fungus inside. At the dollar store I had purchased a bag of ten small plastic containers. One lens into each to keep the parts together.
The back came off after unscrewing three screws. A little metal strip holds the glass prism assembly. Watch out here, it will fly out once it is loosened. The prism needs some cleaning also.
Now I had access to the lens directly in line to the prism assembly. Yup, dirt here also.
At this point I realized that there was a further lens at the rear of the front rotating housing behind the 35mm lens. How to get to it and the other side of the lens mentioned immediately above? Take a look at the photo of the side of the assembly. There is a small dark line, if you put the end of a screwdriver against it in the counter clockwise direction while turning the rotating turret, the whole thing unscrews. It is just snug enough to prevent it from opening when the turret is moved. Now all the glass is accessible.
The part of the assembly that slides into the flash shoe is metal. Hmmmmm, that won’t do with all those contacts on the camera sitting out in the open. I took a pin punch and drove out the pivot pin until I could pull it the rest of the way. I removed all the screws and assorted parts on the base, including the metal flash shoe.
An old VHS video camera light became the donor of a plastic replacement. Some contact cement and a 256 nut and bolt connect it in place.
On to the lenses. I used my own anti fungal solution (you can Google and make your own, I will not recommend anything here). Each and every surface had mold, fogginess or flakes of paint from the interior. Everything cleaned up well enough.
One thing to remember is this is NOT a focusing viewfinder, it just gives the general framing. I will use it when I can’t shove my arms out and walk like a zombie when shooting or when the Sun is causing the screen to be impossible to use.
I have posted many images here as an aid to anyone who starts re-assembly and can’t remember what goes where.
NOTE: The framing will not be perfect, it is meant to give an aid to framing when all else fails to work. Some experimenting between the turret settings and the camera lens settings should give you some ballpark settings.
