Never been a fan of Tamron glass but this tele zoom ticks the boxes when it comes to video work. Parfocal, internal mechanisms, fast and well built. Optically it´s nice too, very competitive in this range of zooms. Very nice to chase stuff around with from afar, especially on a crop sensor (m43). Had a very quick test of it (mainly to see if it was parfocal), and although it´s not exactly cheap I will definately get one when the time is right. Didn´t try out the stabilisation but it seems good.
