Anamorphic rear adapters were used on telephoto canons and Nikkors (ca. 300mm) in the 1990s in US feature film production.
I believe some Panavision Anamorphics used rear element anamorphics in their design.
A product called the mesmerizer from Kish Optics was such a anamorphic rear element mounted in a spinning adapter, which created a psychedelic effect.

The effect is seen here ca. 1:30 and else where (where the whole screen stretches and squeezes:
@Psyco Such a product would be no better than the various anamorphic teleconverters that are available. Anamorphic rear attachments don't have the anamorphic signature that most people want, such as elliptical bokeh.
@psyco +1 I dont have enough optics knowlage to know if its 1 : Doable 2 ; Doable with okay optical performance
Still waiting for an anamorphic speedbooster - maybe from china?
@flyguy depends what you're looking for really. I'm after the lens flare, and the oval bokeh, for a scifi flick I'm starting later this year. Because lens flare is futuristic and all that :)
Bought an LA7200 awhile back but didn't care for the softness. Finally tried out a diopter and was stunned with the results. It's kind of a disadvantage to have to use them because it adds more to the setup and the process but the image quality increase is worth it. You can check out my thoughts and some test images here: http://stronzvanderploeg.net/2012/04/26/anamorphic-shooting-with-the-la7200-part-1/
We want to matte the GH2's LCD screen at top and bottom to reveal only a 2.3:1 horizontal slice. Math is as follows: 16:9 is 1.777:1 - let's say 1.78mm width for every 1mm height [Anamorphic] widescreen aspect ratio is up to you; let's say 2.35 mm width for every 1mm height. The GH2's LCD 16:9 video visible area is 62mm x 35 mm 3 5mm /2.35=14.89 14.89 x 1.78 = 26.5 mm high
We want to put a 26.5 mm letterbox in a 41 mm LCD (Full LCD size, not just 16:9 video) 41-26.5 is 14.5. Half of that (7.25mm) comes of the top. the other half (7.25) comes off the bottom.
This is fairly low risk since you can crop as you wish in post.
Or you can just try printing this pic, aim camera and mark screen. BTW, Vitaly pointed out a way of using GH2's own guide lines.
@Roberto referring for your earlier suggestion on this thread(soft mate style)wanted to ask you what would be the math behind a little DIY anamorphic cover to put on top of the GH2 screen to help me frame better? I will crop the rest of the frame in the editor later. let say for 2.35:1 ? thanks!
I've got a couple of the Cinemorph filters coming (with and without bokeh). I don't think they work with wide angle lenses, I think you're looking at 80mm to get the effect going by their site.
@plasmasmp That bolex looks superb. Very sharp! And of course killer bokeh from the Olympus.
@plasmasmp Strange. Such close face framing, but it doesn't look like cropped at all. If you had used the lens without anamorphic lens, the background would have been compressed more... and it would have looked cropped.
maybe at @Vitaly If i am not mistaken i think there is a anamorphic crop look on magic lantern for canons that let you frame in this format very easily and then can just crop it in the editor(something similar to what Roberto was suggesting here earlier. is there a possibility to add this feature to the future developments ?
There's a thing about anamorphic viewing experience that resembles the real life. In real life, I don't pay attention to every corners that my eyes see. The anamorphic screen is so wide that I can't catch all details in each scene. That seems more close to real life experience.
Anamorphic ratio still photos don't give such experience cuz I can examine every corners in photos. That is the anamorphic magic disappears as soon as I pause the movie.
