Often times I wish my EM-5 would let me set the shutter speed and aperture while selecting the lowest ISO to achieve proper exposure. This is particularly true when I'm indoors like at a concert where the lighting conditions fluctuation very quickly. If I set it to Aperture mode and set the ISO to auto, I notice that the algorithm will often choose a shutter speed that's closer to 1/60 even though I'm using a 17mm lens. This causes my ISO settings to be much higher than I would like. Taking the time to choose the ISO myself to achieve a shutter speed of 1/15 or 1/20 is just too time consuming, especially when indoors with tons of people moving around. Is there a solution to my problem?
