I really like to shoot anamorphic and i spend a lot of time doing little researches, which leads me to invention that i want to introduce. I've learn a lot of information from this subforum, so i want to share my idea here. I believe it gonna be a second breath to independent anamorphic solutions.
So I came up with what anamorphic lenses was originally created for: using whole image sensor area with benefits. Back then there was a film and now we have a 16:9 standart for video and to use it properly id suggest a simple technology: stack together two anamorphic lenses and rotate a camera 90 degree. And then applied 4x coefficient to 9:16 sensor area that results in 2,25:1 ratio:

Of course if u shoot 4K RAW loosing some data is'nt a problem: u're still end up with proper resolution, color and details and even have nice possibility to recompose frame horizontally. But for 1080p recording cameras or 8-bit codecs loosing some data from sensor not the case, is'nt it?) So what do we have:
- 4320x1920 (for 1080p) and 8640x3840 (for 4K) de-squeezed interpolated image that can be downscaled to 1920x850(840) with some color and sharpness benefits
- stack of two anamorphic lenses required longer focal (about 150mm for sankor16f/rectimascope48 stack for FF) but with 4x it comes to pretty the same FOV as 85mm/2x on FF. It also requires smaller aperture to get same DOF. So it results in sharper image with same DOF (multiplied by lack of loss resolution in the camera). Of course increased number of glasses results in some lights losses, about 1 stop i think, maybe less.
- one of the nicest feature of my scheme: it kills rolling shutter effect. I develope idea of that anamorphic solution with a7s model in mind, it's a great camera which suffer from well knowed issue: terrible RS. But when you rotate sensor and applied 4x stack of anamorhic you decreased RS effect in the final image by 4 times (since RS effect appears on horizontal which is became vertical). From now on forget about RS)
- and one issue: its getting even harder to look at monitor: now its 4 times squeezed image. Honestly i always like to shoot anamorphic without desqueezing function that gives me some abstraction and somehow another vision of composition and im not suffering much from 4x squeezing to. Its hard to use monitor to nail a focus but easier with viewfinder. Actually i send a letter to atomos with asking for some cooperation here but got no respond (maybe a reason is my broken english, who know : )
Of course stack of two anamorphots is loosing any ability to focus, but it working well with diopters like usual combo of taking lens and ana - just set them all to infinity.
And im asking here for some help. Im already tested my prototype (later im gonna do post about it) with usual diopters and it worked. But to use it properly i need some variable diopters and for now i can afford only SLR Rangefinder, which have not very high perfomance. But since aperture at my taking lens starts with 3,5 it may work. I know here's a guy, Tito, with a lot of anamorphic stuff, i will ask him for test, but maybe anyone have opportunity to try it to?
PS I know my English is bad so i provided some pic for u guys)

My setup for you.

FOV is certainly wider, but I can also achieve that same width with 1 anamorphic and a lot less hassle. DOF wasn't noticably better to my eye, but I'm also not really in search of anything shallower than I can already achieve, I usually don't shoot wide open much anyway (close ups often at f4-5.6).

The best part about it was trying to work out how it would look de-squeezed, it's like christmas when you see the end result .

Im not sure, its easy to clear that - FB accounts have a persons name
thats why that topic was started - to get more setups and results to share)
im not thinking - i know, already tested it as i state earlier
Here is what my prototype look like:

Jupiter37A / D.O.Industries 16F / Rectimascope48 and housing made of 7 step-up rings, 2 empty filters, 2 lens hoods and one inner filters thread to assemble it altogether

Ed David might have some. He used to shoot with it a lot I think.

Here's some tips for u, maybe it will be helpfull: take some long focal lens and set it in focus (as much as possible in current condition) with rectimascope, u can use page with small font text as a focus target, loose the screws on a back lens of rectimascop, put rubberglove and place two fingers on opposite sides of a glass so there is space in between so u can see a result of your rotations in liveview (of course set it to max zoom). When u get a best sharpness press a glass tightly so it cant rotate anymore, put rectimascope vertically and tighten it. Then check sharpness again using liveview. Thats how i set sharpness with my d.o.industries 16f, things were easier for me because i rotate front glass, but i hope that scheme will work for u to)
