Lightwriting with Sigma

When using the sigma what are you sacrificing? Focusing speed?
Is it still 2x crop?

The sigma with the adapter would only be manual focus. Crop with a normal adapter is still 2x but with a metabones speedbooster the crop decreases to 1.42x and you gain an extra stop, so the f1.8 becomes I think f1.1 or 1.2.

You actually gain? At no iq sacrifice?

Actually you gain resolution. Or to put it in another words, you re-gain the resolution that is lost because of cropping, because the cropping gets smaller.
