Hi guys Has anyone got any example photos they've taken at festivals at night using either the Oly 17mm or the Pana 25mm? Using available light only, no flash, wide aperture, high ISO, etc. I am heading to Glastonbury Festival in a couple of weeks and am thinking of adding either of these lenses to my existing collection (see signature) to be able to take photos at night. Understandably AF ability in low light is important, from all the reading I've done it sounds like the Oly has it over the Pana in this scenario, especially when coupled with an OM-D? Whereas the Panasonic may be prone to a bit of hunting?
