telephoto zoom 2.8 lenses are heavy and a bit cumbersome to carry around. Pero sanayan lang yan. bring a tripod if your tele has a tripod collar para mas convenient gamitin. once you get used to this... its very good for portraits and events... specially at low light conditions...
the 85mm prime is a sharp and handy lens... ok sya pag low light kaso be ready to do alot of "dancing" aka foot zoom to adjust with you subject. masarap gamit ito for bokeh effect. i've owned and use one before... all i can say is that this is much lighter and quite fun to use...
buy after testing my nikon tele... i prefer to use the tele for photoshoots kasi mas convenient and easier to compose shots...
