hidalgoserra Posted November 3, 2015 Share Posted November 3, 2015 Hello people,i am trying to find out some info on that matter, but apparently is harder then i though.First of all is a speed booster like the metabones or Rj turbo usable on a canon mark III? and if yes which version should i take considering seems there are several out there with different mounts.Thanks Link to comment Share on other sites More sharing options...
BrorSvensson Posted November 3, 2015 Share Posted November 3, 2015 Why would you want to put a full frame converter on a full frame camera?? And no it can not be mounted, it can only be mounted on mirrorless camera becuase of the flange distance. Link to comment Share on other sites More sharing options...
David Bowgett Posted November 3, 2015 Share Posted November 3, 2015 I don't think the 5D Mark III has an APS-C video mode, so there'd be no benefit to attaching one even if it existed. And while I suppose it's theoretically possible for someone to produce a speed booster for a full-frame camera, you'd likely need medium-format lenses for it to actually work.

richg101 Posted November 3, 2015 Share Posted November 3, 2015 unfortunately for a speed booster to work you need to get nice and close to the sensor - canon's mirror gets in the way. Link to comment Share on other sites More sharing options...
hidalgoserra Posted November 3, 2015 Author Share Posted November 3, 2015 Thanks to clarify that point, i was getting mixed info now at least i know for sure.My question is, there is anything similar to a speedbooster for full frame cameras? something to enchance the field of view of a lens and his aperture?

tupp Posted November 3, 2015 Share Posted November 3, 2015 My question is, there is anything similar to a speedbooster for full frame cameras? something to enchance the field of view of a lens and his aperture?You can use a wide angle adapter that fits on the front of the lens, but you won't get a gain in brightness. The cheaper wide angle adapters sometimes exhibit a slight loss in sharpness, but a few brands such as Century Precision Optics (now Century Schneider) have very sharp adapters.

Hans Punk Posted November 3, 2015 Share Posted November 3, 2015 The only possible benefit from permanently removing mirror and box from Full frame canon dslr to accommodate speedbooster optics would be when shooting crop mode with Magic Lantern Raw. Then the heavy crop mode would be optically reduced to around s35 (or slightly under) but will allow higher resolutions to be recorded (for short periods). The optics would have to be professionally installed and would effectively restrict the camera to ML crop mode only. Andrew Reid 1 Link to comment Share on other sites More sharing options...

The optics would have to be professionally installed and would effectively restrict the camera to ML crop mode only.This argument assumes that one is using a full-frame lens along with a typically sized focal reduction element. As David Bowgett mentioned above, one could start with a medium format lens and also use a larger focal reduction element (perhaps something like this).Not sure if such a large focal reduction element would have to be positioned inside the camera, but both pros and "amateurs" have modified Canon HDSLRs to internally accommodate larger optical systems.

Lintelfilm Posted November 5, 2015 Share Posted November 5, 2015 We'll all be chasing the Alexa 65 and Red Weapon Vista Vision look soon enough. Perhaps if we throw enough money at him Richard Gale will build a VV adapter for the A7S ... Link to comment Share on other sites More sharing options...
