Dating rolleiflex serial number
I also have a MX-EVS and a couple of Yashichas, a 124G and a 44. I carefully placed it in my "museum" (which is really just a bookcase with all my old cameras - with a glass door to keep out the dust).
I never tried to use it, but after I got the retro-bug I tried various places to see if I could get it serviced.
So I started looking for an alternate and found a Yashicamat 124G in almost mint condition.
I bought it and had the seals replaced, and have been messing with it ever since. I have to think a whole lot more than with the digital stuff.
The Hi-Lux screen, plain with a grid is slightly brighter than #1 above in low light in the corners, and the fresnel snaps into focus nicely. Note: Both Maxwell screens are a lot brighter than the original Rolleiflex screen.
I'm researching the camera to determine what value it has. I used it in 1963-64 and it took great photos of a ski trip to Aspen. Note that there is also the Shutter-Speed-Tester app for Apple IOS and Android that measures the accuracy of the shutter based on the sounds.
The Rolleiflex is the first of the modern twin-lens reflex (TLR) cameras.
Photographica World 154 has a very good article on the Original Rolleiflex by Jos Paula.
Nobody would touch it (they do Flexes but not Cords).
Not wanting to damage it, I started checking out Rolleiflexes and WOW was I surprised at the price for a good used one.
