Cinemorph Anamorphic-ish Filter

seems similar to the thing that Timur Civan (a member here) is working on. yes it does look good....losing 2 stops of light isnt though.

I've just now seen his thread, indeed may be about the same, but the last post there seems to be from 11-2010? Any news about that?
 
In a nut shell, its basically 2 or 3 techniques that have been around for decades (bokeh & flare / streaks) rolled up into one, but add to it high quality optical glass and a smooth rotating frame. We're working on making this better and better! Right now it's assembled by hand. We're working with an optical company to obtain an even higher standard of glass that might minimize light loss as well as a price drop. But no matter what I think we're looking at at least 1.5 stops...its hard to avoid when you're essentially blocking the lens with a filter like this. Not a huge deal with a fast lens on a full frame like the 5D but a slow lens on a t2i might suffer. The night footage video was shot at about 800 ISO, so there was still plenty of room to crank it. More footage coming very soon...

It's a lot of fun to shoot with. We're working on some before and after rack focus tests with various lenses this week. We'll have the footage up in the coming days.

And as for light loss when shooting with the filter at f1.8 on an 85mm lens, to match the light level on the same shot without the filter, we had to stop the lens down to slightly under f2.8 (f2.5ish)...there always seems to be confusion on what people consider a full stop of light.

Hope this helps....more to come....

very interesting indeed. will be following the developments on this. I echo 77mm to cover any lens i may get, so i can use step up rings.
 
Actually, you should know that these wont be a 1 filter fits all kind of deal. Various sizes will be needed for various lenses depending on focal length, sensor size, and how far recessed the front lens element is. Its ideal that you use prime lenses and fast speed lenses too (f1.4 to f2.8). Right now the CineMorph58 seems to work on the widest variety of lenses.
Zoom lenses will work but for instance you may get vignetting on the wide end. You'll always have the flares, but the other characteristics may suffer if the wrong lens is attached on the wrong CineMorph filter.

We'll have much more specs and info coming soon about which specific sizes work best on which lenses...
 
All the footage so far has been shot on a 5D Mark II (full frame of course). Shooting some new clips with a 7D and t2i (cropped frame) tonight.
 
So it would not work well to get one 72 mm and attach it to a smaller lens (i.e. 52mm) with a set-up ring?

I guess the aperture would look strange...
that is unfortuante (but understandable)....
 
We're huge fans of the old school Nikon lenses. To be honest I personally dont even like using Canon lenses anymore. The Canon are nice for stills but the older lenses seem more practical for Cinema style shooting. The CineMorph 58mm filter works great with the old Nikon 85mm, 100mm, 200mm all of which were attached using a 52mm-58mm step up ring.

The old Nikon 50mm works well on a crop frame camera like the t2i or 7D.

Oold M42 mount lenses: The Jupiter 85mm f2, TAIR 135mm f2.8 work great too on both 5D and 7D!

And the Helios 58mm and Takumar 55mm f1.8 work well with a crop frame camera.

Pretty much all the same prime lenses that were ideal for regular anamorphic combos, are ideal for the CineMorphics as well. :happy:
 
Just to be clear...JPM asked a question which i am also interested in..and maybe its in your answer but i'm not getting it. If i get a 72 or 77mm cinemorphic...i can't use it on smaller sized lenses with a step up ring?
 
To answer your question, it might work on some but not all lenses. Variables include sensor size of the camera and how large or small far the front element is and how much it is recessed. And of course focal length of the lens.
The flares will always be there of course but the other characteristics might suffer by either shooting through the bokeh effect if the filter is too wide and the lens has a long focal length or not clearing it if the lens is too wide causing vignetting.
Our 77mm prototype works well on a large variety of lenses...the problem is that wider lenses on a full frame start to vignette, but that happens on 58mm filter as well.
Here are some samples with a t2i / 550D (cropped frame), Nikon E 50mm f1.8 and the CineMorph 58: http://vimeo.com/19796520

When they're ready we will have a chart as to which filters work best with which lenses...

Very cool. I might have missed this, but does the filter require a de-squeezing of the footage in post or is it simply a matter of hard-matting the footage in post? If it requires de-squeezing, what is aspect ratio multiplier: 1.33x, 1.5x, 2x, or? Keep up the good work!
 
Thanks qwerty123, you have the most easiest screen name to remember ;)

No sequeezing or desqueezing with this sytem. It keeps your vidoe at 16:9. You'll hard-matte or crop in post. Which I found very nice for repositioning and recomposing the shot later...sort of like working with 3K or 4K footage.
