    Metabones Speed Booster lens adapter

    I think this is going to cause quite a stir in the video/cinema world.

    http://www.metabones.com/info/105-in...-speed-booster

    It's an adapter that lets you mount Canon EF lenses (which are made for a "full-frame" sensor, or 35mm still film) onto the Sony NEX cameras (which are mirrorless and have an APS-C or s35 size sensor)... but with almost no crop factor, while also increasing the speed of the lens.

    So, in the past, if you mounted, say, an old manual 50mm f1.4 lens on your NEX camera, the field of view would look like a 75mm lens would on a full-frame camera. Now, with this thing, your FOV would still look like it would on full-frame, AND all your apertures would be effectively one stop brighter (so your max aperture would now be a f1.0)!

    It says other lens and camera mounts are in the works... I really hope they do m4/3 next.

    these are the same people that made the other canon to sony lens adapter that did well. should be awesome for stuff like the fs100 and 700 but say you have a 1.8 lens that would go down to a point 8? doest leave much focal length and would the lens still be a sharp. I would like to see some wide open footage with it this footage made it look damn good tho

        I thought a stop was like an increment. Like the nifty fifty goes 1.8, 2.0, 2.2, etc. So a STOP, would mean that you should get to 1.4 using the 50mm 1.8....


        I think.

            A stop is an increment of light. Each stop represents a doubling or halving of total light compared to the next full stop above or below it. Stops can be used to describe any aspect of exposure: shutter speed, aperture, ISO/gain, or even ND filters. F-number describes the physical size of the aperture diameter compared to the focal length of the lens.

            In stops, this adapter sends one stop more (twice as much) light into the camera. In f-numbers, this adapter would take an f1.8 lens and make it about an f1.3.

              I'd love an m4/3 adapter, but if the pricing of the NEX adapter is any indication of a pricing range, the m4/3 adapter would end up being 2-3x the cost of my m4/3 camera itself.
              soon.
