Hi All, I've got a Panasonic Ag AF 102 series camera. Looking at a new fast aperture lense with zoom for filming. I'm tossing up between the Olympus Zuiko 14-35 f2 and the new Panasonic x12-35 f2.8. I know for a fact the Olympus is way more pricey than the Panasonic. I've personally handled the Olympus 14-35, and found it an excellent lense, but I've also heard some negative feedback for the Olympus. I have no idea what to expect with the Panasonic 12-35 f2.8 lense. Would anyone consider this over the Olympus? Is it as good value as it seems? What are your thoughts? All suggestions are appreciated. I currently own a Lumix 14-140 and a voigtlander 25mm prime. The Panasonic 14-140 is personally crap in low light, and the voigtlander is absolutely stunning for video, but its only a prime, and would prefer a good zoom for low light. Any suggestions? Thanks.
