Metabones Speed booster Mirrorless Adapter

I've been using the micro four-thirds system for a while now and I love the system for its portability. The only issue I have with the micro four-thirds system is the lack of fast and affordable lenses. I love using prime lenses. I have a few fast legacy prime lenses to cover my need for fast primes. The only problem with the legacy lenses is the lack of autofocus.

A few days ago, I read an article from 43rumors that made me love more of the micro four-thirds system. Metabones is going to introduce a new adapter which will increase the speed of the lenses by a full stop. It will also widen the focal length by a factor of  0.70x. Which will bring the crop factor of the Micro Four Thirds system to 1.40x.



The huge advantage of this adapter is it increases the amount of light the lens gathers. Since it will increase the f stop of a lens, four-thirds users will be able to convert affordable legacy lenses into a very fast lens. The downside to the adapter is it compresses the area projected by a full-frame lens into the size of the smaller micro four-thirds sensor. There will be a decrease in sharpness on the corners.

If you attached a 50mm f1.4 to the metabones adapter it will become a 35mm f1.0 lens. Since the micro four-thirds system has a 2x crop factor, the lens will be turned into a 70mm f1.0.  If you add the cost of the adapter, which is around $600, to the Canon 50 mm f1.4 $399 lens, bringing the total cost of the whole setup to $999. The Canon EF 85 mm f1.2L II USM Lens costing $1,999.00 is the nearest lens to this setup. This lens has a significantly lower f-stop compared to the converted 70mmf1.0 lens.

I'm still not sure how the AF system of these adapted lenses will work on the adapter. If the EF-S or DX lenses are compatible with the micro four-thirds system adapter. I think we 're just going to have to wait for a full review to come out.

I think the metabones adapter is going to be a game-changer for the mirrorless system. If Sony, Olympus, or Panasonic can create a camera that can harness the full potential of the AF of Phase detection lenses, I think people will begin to notice the amazing technology of mirrorless cameras.
