How do I attach a Rolleinar?

[jacobmiles]

Hello. I have a Rolleicord III and I bought a Rolleinar 1. I'm confused as to

how to attach it to the camera - there are three separate lenses, two of the

same flat size and then a thicker one. All of them are able to attach to either

the taking lens or the viewing lens, and they stack so I could put the thicker

one on one of the thinner ones. My guess is that the thicker one handles

parallax, but I don't know which lens it goes on.

 

Any help?

 

Also - I've read some posts that say that the Rolleinars only sort of help

parallax, that they fix the viewable area but not the angle of view. What does

that mean? I thought parallax was the different angle of view.

Scroll down to Rolleinars.

 

I love Google...

The Rolleinar corrects for FRAMING, like the moving mast in a Rolleiflex (but not AFAIK Rolleicord) finder, or the moving frame in the viewfinder parallax-corrected RF camera. If, for example, you line objects up one behind the other on the screen, they will not be lined up on the negative (although you'll not cut the tops off) because, even though the framing is correct, the angle of view of the viewing anfd taking lenses is different.

The thicker one goes on top and the other two are diopters (do they have the same or a different # on them), but for the framing to be correct the thicker one must have the same # on it as the diopter.

Robert, the parallax correction (moving frame) was first introduced in the 1933 Art Deco Rolleicord up to the last one the Vb. The Rolleiflex got this feature in the 1937 Automat. It lacks in the Rolleiflex Old Standards as well as the New Standard of 1939.

 

Going back to the question. The manual (Butkus) shows the application of the newer Rolleinars with 2 elements.

 

Jacob has the 3 elements. For the 3 element Rolleinars one should attach both Rolleinars on the taking & viewing lenses (flat ones). After that, attach the Rolleipar on the Rolleinar over the viewing lens. Make sure that the little mark is at its top.

I stand correctes Carlos--I guess it's just the (upside down)eye-level focusing, with the sportsfinder, that the 'cords lack.

The Rolleiflex T hood lacks the lens and mirror for eye-level focussing. Sine the hood is interchangeable on the T I managed to find a used hood from a Rollei F and put it on my T.
