GX80/85 + Canon SB + Sigma 18-35mm, correct focal length?

Hi all,

Question for anyone who owns a Panasonic GX80/85, Canon Speed booster that communicates EXIF data and the Sigma 18-35mm: If I use the Sigma 18-35mm attached via an electronic speed booster will it correctly communicate the focal length and therefore will the sensor stabilisation be correctly tuned for that focal length as you zoom in and out?

I'm sure Metabones have thought about this, but with the 0.71x will 18mm be communicated as 12.78mm so the camera knows what it is dealing with?

I currently own non-electronic lenses and adapters but thinking of going for the Sigma lens in Canon mount and combining it with the GX80/85 (and upcoming GH5) via a speed booster for handheld work. Would be a killer combo and could sell my Zacuto shoulder brace and not need my primes for lowlight work. Less kit is more!
