The no-shallow DOF argument may no longer be all that valid if the new Metabones speed booster lives up to its hype. Purportedly you get FF DOF with your NEX/MFT.

It should, I would think, be possible to design a crazy fast lens using the metabones type of design integral to a lens. I'm assuming this could be done and have the lens be reasonable size/price.

unfortunately, AF with the speed booster is slower than using the EOS M, according to Roger Cicala. so maybe a fruitless pursuit after all.

Don't know that I care about AF with a lens at f/0.5 - what would it possibly fix on? I'm thinking MF w/liveview. Agreed, not for every lens, but I would really go for a 24mm (eq FF FOV) f/1

well, I know if I were using a 24mm f/1.4 L on a full frame DSLR, I'd certainly expect its autofocus to work

AF from 5 feet from subject at f/1.4? I'm skeptical you'd get any kind of shot that makes sense.

For subjects at close distance, the primes can produce nice background blur.  The lack of very large aperture lenses is just in keeping with m43 philosophy of small and light.  For a similar reason, there are no large aperture longer lenses.  But overall, it is a good compromise system.  It just needs a few more tweaks of the AF speed and a reasonably priced, high quality 300mm f/2.8.
