Has anybody tried either the Tamron 150-600 VC or Sigma 150-600 OS C + any 2x TC for 1080p video work? How's the VQ?

I expect IQ at 1200 mm for stills will not be quite good. However, say on the 7D II, the sensor's original video capture will be down-sampled by the equivalent of about 3 stops to 1080p, hence easily cancelling the effect of the 2x TC (2 stops up-sampling).

TIA,

Romy
