What benefits will the Speedbooster give? The image the FD gives me on my GF2 is pretty impressive with the cheap ebay adapter I have.
The two major flaws of the Blackmagic Cinema Cameras are poor low-light sensitivity, and an excessive crop factor of almost 3x. A Lens Turbo/Speed Booster dramatically reduces these problems.
To go back to the original post I think that there is a point you actually missed about what you call crop Factor.
In traditional Cinematography a Super 35 kit would e.G. consist of a 32mm, 50mm and 75mm Lens. (there are of course some Variations as a 28 or 35 instead of a 32 and a 85 instead of a 75 e.G.).
If you compare that to a typical set of S16 Lenses you will find that a kit of those would be a 12mm 16mm and 25mm Lens. Given the fact that you have a approximate Cropfactor of 2x from S16 to S35 these would have the same angle of view as a 24mm, 32mm and 50mm lens on a S35 sensor. However as the image circle of these lenses can be smaller it is easier to make them faster without a massive increase in size and or weight.
So while a 50mm S35 Lens could typically be something from T2-T2.2 a S16 25mm Lens could be T1.6 or even faster. As result of this the the depth of field from those lenses might actually be closer together then thought.
Regarding the quality of the Image outputted by the Sensor you will also have to understand that resolution is fixed on the sensor so while shooting on film a S35 Frame contains more physical information then a S16 Frame this wont apply for all digital Sensors.
For example a Frame of a BMPCC would contain the same amount of Pixels as that of a PMW-F3 for the simple reason that the Pixles are bigger on the F3.
The initial problem with people complaining about the missing option of wide lenses came from people joining with a pure Photography background being used to odd lenses as a 14mm F2.8 FF lens e.g. .
Whilst this might be seen as an usual wide lens on a stills camera this is an crazily wide lens to the standards of cinematography.
In conclusion the problem you seem to have with S16 is that you want to use pointless lenses with it.
To put it photographic terms, you would neither use your 210 F5.6 Large formate standard lens on your full frame body as a replacement for a FF 50mm Prime.
And considering lowlight, even though this is quite a different topic... .
If you are all about lowlight you should rather lean towards The FS700 with an S-Log2 option having a base ISO of 2000. However bare in mind that ISO 2000 will be troublesome when shooting in bright light even considering that the FS700 has built in ND filters.
