The 20mm pancake can support the la7200 with metal step rings just fine. Been using it this way for 8 months.

Focus works like this:
F4+ 6ft-infinity can be focused
under F4 you need a +1 diopter which will let you go 3ft-20ft focusing.

All anamorphic lenses focus on a curved plane, so you'll need to learn to deal with that. Its a bit much on the la7200, but the lens is the closest you can get to a 1.33x hawk lens.

Personally I don't like 2x anamorphic lenses on 1080p sensors. Works ok for RED with the resolution you have to spare, but it kills too much detail on a lesser 1080p sensor. Its fine for streaming, not ok for broadcast or distribution.

Also what about :
Century Precision Optics 1.33x Anamorphic Converter Lens for Video Lenses with a 58mm Filter Thread
is there a chance to find one ?

Got the CineMorph, review soon. It doesn't replace a proper lens.

LA7200 would be a good choice for you but expensive now, $1000+. So Optex or Century next best thing. The LA7200 works with the 14mm pancake well. Not tried others on it though. I had the Optex on a 9-18mm Olympus. Canon 10-22mm also works well.

You should post a little video of a DIY type of cinemorph adapter. I think it would be nice. As for me I have been looking for a long time about the anamorphic thing. In some thread on Dvxuser I called it the missing link, because since the advent of the hdslr, we have really approached the film look esthetics. Now if somebody has some talent, ideas etc he can make a movie or a short that won't look too far from the movie at the cinema ( Not a block buster with tons of special effect etc). But the only thing that is missing is the anamorphic look.

In the end since the price of some solution have sky rocketed, I have decided that it did not make sense. That cropping in post was the best bet. I want to be in the filmmaking so many of the solutions are not practical at all, for focusing, crop factor etc. One company would have a very good solution and it is Panasonic. An updated la7200 for hd, better glass etc would have been nice. I have tried to float the idea on the other forum but it did not have any big response. I thought that with Jan on the forum, a strong community might have influenced Panasonic to do such an update. People seemed more interested to fiddle with completely unpractical solution ( that will end only as experimentation in not so long), or those who can buy what was at $ 300 -$ 400 for ten time the price.

The problem with anamorphic is that the pro version of thase are in the tens of thousand of dollars, so they will remain unatainable to the indie crowd until some stop gap ala revised la7200 comes along.

that's all a Cinemorph filter is. an oval and a piece of fishing line for flare. I'm dead serious. If you're set on oval Bokeh another idea I had was to get a Lensbaby (fun tool to have besides anamorphic stuff), and use the creative apertures kit to get oval bokeh: http://lensbaby.com/accessories-creative.php

@feha @plasmasmp uses a pancake with the LA7200. Makes for a very compact anamorphic rig. Might be worth asking him how he mounts his, otherwise a rails solution would work.

@B3Guy
thank you, I'll forget Cinemorph filters :-)

@Ptchaw

Thank you, yes i have been following EOSHD.
LA7200 i think would be too big, heavy for 20mm 1.7 pancake.
OpTex 58mm anamorphic attachment don't know the weight but i think would work with pancake.
I'm new to anamorphic field and have no experience.
Below is a video that i was impressed:
