Build quality is great and the glass is high quality, no loss in sharpness of the images. However it does not have hard stops (which I prefer in a VND) and it has a strong color cast and loss of color/contrast making it practically useless under the Greek sun. It also has the dreaded X at max strength. For photography I recommend a series of (magnetic) filters and for video find a higher quality one, maybe with step up rings to save cost.
