I have this lens attachment for projector lens for awhile, Rathenower Rectimascope 48/2x. I dont have time to play with it. Because it has to be clamped on front of normal lens.
I have to stopped down at least f5,6-f8 to get sharp enough image.
I put it in Meyer Trioplan N 100/2,8 V handheld, because I dont have the right setup.
First sample the image strected horizontally, the 2nd one was vertically
|anamorphic twisted wide, everything including the man looks fat LOL|
|anamorphic set, everything looks thinner|
|after edited to make it right|
|original with trioplan, without anamorphic|
