Tamron 24-70mm VC f/2.8 (VC on sharpness test real world example) HD

Watch in full HD. Been seeing warnings of the VC degrading the images in photos taken at or faster than FL. here i have a close look at the image quality at the different apertures and focal lengths (FL) and note down the sharpness in both the centre and edges and the vignetting and an odd exposure change.
