I recently purchased an EOSR. I love it, but one thing is annoying me. With my previous camera 5D3, taking landscapes in full manual, when adjusting the exposure settings by hand, I used to keep an eye in the internal light meter reading as well as the histogram to obtain the best possible exposure. With my new EOSR, the histogram is grand but the light meter indicator is just frozen, it doesn't show exposure or light level? Can it be turned on ???
