Sinar 5x7 & 4x5 TLR 200mm Imagon Pair 2 by Nokton48, on Flickr
Here is another matched pair of lenses for the 5x7/4x5 TLR Sinar Norma. The bottom viewing lens is a barrel 200mm Imagon, the top taking lens is a 200mm Imagon forward mounted in Compound shutter. This covers 5x7 for this application and is a lovely addition to the lens bank.

250mm Imagon matching pair (one barrel one in lower spot, and compound shutter top taking lens in top), mounted matched pair, barrel lens presently attached with blue painter's masking tape, needs flange attached with micro hobby modeling brass screws. Mini drill press makes lots of holes quick and precise. This will take about an hour to finish including painting. Next project is same exact deal set up, but with matching 200mm Imagon pair, for all lenses I prefer the H5.8 discs but with the petals fully closed.
I'd like to have additional supplemental aperture discs printed. I've seen this very thing done with old 4x5 plastic dark slides laser cut. A set of standards " Imagon Waterhouse Stops" cut from old plastic darkslides for each Imagon would be the final goal

Hi Serge
Thanks
Normally it ends up with the H 7.7/9.5 half closed but it depends on the light condition
which have large influence to the 'Imagon behavior'.
The amount of the 'Imagon behavior' is controled by using tllts/swings to control the plane of focus.
The amount of the look that I call 'Imagon behavior' depends on the sharpness.
I like to have minimal influenced ereas in the picture.
Sometimes I use a +3 Dioptrien in front without any stainer. It's interesting to control what's happening
with the opening of the shutter aperture, see the picture with the rowing boat. Btw the +3 Dioptrien gives you a larger angle of view.
@Daniel
Nice setup!!!!
