Can you say ISO 3200?
5D, 200mm, ISO 1600, 1/60, f/4, -1 ev
One stop of underexposure and ISO 1600 – the sort of thing that would have film in tears. Par for the course with the low noise 5D’s sensor. I do wish the 200mm L lens had IS (1/60 is really slow with this focal length), but this will do for now.
