Question for all the stage and theater shooters out there. I've been using my XT2 and 18-55 to shot my theater work and am thinking about getting the 16-55. Will it be worth it? Seeing that the 16-55 will not have OIS and the 18-55 does. My typical stage shots are set to 1/60s-1/120s at iso1600 or 800 if I am lucky with the lights, and the 18-55 usually wide opened. Am I going to get any sharpness advantage with the 16-55? Yes, I can get the new XH1 but the size and price of that camera do not agree with me. Also, I do not shoot video at all so even less of an incentive for me to get the camer
