One advantage the 1DC has is out-of-the-box nice looking images. I use the 5D3 as a reference to re-tune the FS700+MB output (can match pretty closely). So, the 1DC can save time, and time is money.

Thanks for the tests JCS, good info.

I'm going to use the FS700 + MB SB to create sharper, full frame cat videos for youtube. That and test charts. Maybe combine the two concepts and shoot a Hello Kitty test chart.

It's not just about full frame support (though I admit that's what got my attention as a 5D2/5D3 owner with Canon lenses). They named it "Speed Booster" and not "Full Framester": the light gathering and focusing nature of the device is very cool. My 50 F1.4 becomes an F1.0, the 24-105 F4L becomes an F2.8, 70-200 F2.8 II becomes an F2.0 etc. The last feature which most people find hard to believe is the increase in image quality (improved MTF- modulation transfer function). This is measurable (they show graphs), and example images with reduced CA, increased sharpness and contrast: http://www.metabones.com/images/metabones/Speed%20Booster%20White%20Paper.pdf
 
Lots more example photos and videos from real-world use here: http://philipbloom.net/2013/01/13/speedbooster/
 
A minor technicality- the device is actually a 1.09 crop (close enough :)).

According to the MB whitepaper*, the SB will increase image quality (measurable MTF) in the same way an extender reduces image quality. If accurate (in mass production- the math/physics makes sense), that means that not only is FF possible and -1 effective f-stop, but also higher IQ. I ordered the SB and and FS700 to test. If it works as advertised, the FS700+SB looks to be the most affordable/versatile pro camera right now (S35 and FF, very low light, multiple frame rates, super slomo, true 1080p pixels). C300 has better ergonomics and perhaps a more bulletproof internal codec, but has far less features and costs $16k.

This scene shot at 24mm with a FaderND gen 1 (works fine with the 24-105 lens) looks sharper than normal for a detailed wide angle shot: https://vimeo.com/40107424

It's not sharp, but it appears sharper than normal and requires less post sharpening (about 1/2 the amount). This example shows moire (church), which I haven't seen before with the 5D3 (well, have seen it before but very minor). More details in the vimeo description and original MOV available for download. Banding in sky likely due to using CineStyle and over-exposing the shot (could fix in post if this shot was needed using noise/grain or selective blurring with AE or Resolve).

If anyone has a FaderND (any version), Heliopan, etc., or clear linear/circular polarizers, would helpful to know if polarizers can help improve sharpness (some OLPFs use a polarizer- might be some kind of interaction with polarized light which reduces diffusion and blur).
