A question for those with more experience than I...
I have an Exa along with the penta-prism / hooded finder as shown in the picture ...
When I have the "hooded finder" installed The camera develops tunnel vision - the field of view is like the "sketch" below ...
Is this a quirk of the gear or an indicator that the finder is missing something?
Thanks in advance for future help.

No Jim, I've just tried the same set up for you and the view is normal. The view you have seems to be of the back of the lens via the mirror in cocked position, which you can see when you have no viewfinder on at all. No offence, but just to eliminate it - are you sure the viewfinder has its focusing block installed ? It's the only thing I can think of at the minute. I'll keep thinking. |

Thanks for the quick reply . . .
Here is a comparison of the two _ waist level vs hooded . . .
I guess something is missing . . . or is it a separate part?
The one in the waist level is firmly secured and I don't want to risk mucking with it.
The base of the hooded shows grooves and such, as well as 2 pins.

^^Yes, from the pictures, the focusing screen you show is missing from your eye level finder. The waist level (hooded) finder, as you say, has its focusing block in place. |

many cameras the focusing screen is fitted on the body, not finder
but it is flat, this is some sort of "new technology" in it's age _________________ MF: Kodak DCS SLR/c; Samsung NX10; OM-10; Canon T50

Yes, Ihagee introduced it in their new Exakta Varex line in 1950 and in the new Exa line of 1951. The compact Exa and 'big brother' Exakta cameras could exchange lenses, viewfinders and focusing screens between each other. And when you think about it, changing the screen is much easier if it is simply a press fit on a pop out viewfinder, so I'm guessing it made sense back in the day.
With regard to the shape of the focusing screen, I'm afraid the reasons are beyond my knowledge. I know there was a flat ground glass available for reproduction work. |

This answers many things and I can put things into proper order and gain a usable finder.

I really never want to go near the Kolpofot device.
With the flash 500 volt power source.

Me neither.
I do have some of those accessories though, - just the bellows, rings and weird shutter release. They are very well made. |

The photos and not the photographic process is allowed to be shocking.

The top of the Exakta focus screen is curved because it is also performing the function of the condenser, which is usually a separate piece in modern viewfinders. |
