Rapido Single Focus Solution Test Video

Recommended Posts

Check out the test video of the Rapido Single Focus Solution, my setup is as follows:

  • Camera: GH4
  • Taking Lens: Rokion 85mm T1.5 Cine Lens for CANON
  • Anamorphic Lens:  KOWA for Bell & Howell
  • Anamorphic Clamp: Rapido V2 Clamp
  • ISO setting: 1600
  • Shutter speed: 400
  • Aperture: T1.5
  • Video format: MOV, FHD
  • Aspect ratio: 3.556:1 (1920:1080 with 2X anamorphic squeeze)

The minimum focus is 1 meter. Different anamorphic lenses are used as focus targets,  set between 1 meter and 2.5 meters from the camera.  The video shows racking focusing from close focus to infinity.

The aperture is kept wide open at T1.5. There is no sharpness drop comparing to the original Kowa & Rokinon combination, and there is no change of the original flare/bokeh character from the anamorphic lens.  This is the main difference comparing to other Single Focus Solutions, like SLR Magics, FM Module, and Rectilux.

More test videos will be uploaded soon.

I love this clamp setup, my rig works great!

Hi that sounds really good!

if you are working on a new single focus device and it's still in R&D, I would highly suggest you work also on the mechanical part of it.

The perfect single focus device would have a front filter thread/ring that does not rotate, to be able to mount a clip-on mattebox in exemple. the competitors does not have it and it's really annoying.

also the distance travelled by the focusing ring is too long both on the "SLR magic range finder" and on the Core DNA. if you can develop a system that does not travel, that would be awesome and would allow to fix the mattebox bracket to the rods steadily and not letting it slide on them.

- fixed/non rotating front filter/ring for standard cinema clip on mattebox

- non travelling focus ring

- neutral color flares

- metric and imperial marks

-  for the price of the rangefinder

 

if you have the 5  features, your system will sell millions of them!

Good luck in your R&D ;)

I'm pretty sure the Rectilux Hardcore DNA has all these features ;)

The big question will be the price and availability of course. (Rectilux Hardcore DNA is £750 and come in small batches)

You are right, mechanical is an important part of the system. At this point, I don't have time to develop a one for all type of single focus solution, the focus will be on the image quality, sharpness & neutral color flares. 

After this, I will probably provide lens rehouse service, which rehouse the single focus solution & the anamorphic lens as one single lens. Then all the mechanical side of the design will be addressed.

You read my mind! I thought about that a long time ago and I think this would be awesome.
