Low-light, natural lighting test with Canon 5D Mark II & Sony NEX-5N. No color-grading, straight out of the camera. I tried to get it as close as I could in-camera. Can you guess which is which?
Canon 5D Mark II: Cinestyle Preset, 50mm f1.8, ISO 100
Sony NEX-5N: Portrait Preset, 28mm @ 44mm (1.6 crop factor) f1.8, ISO 100
Conclusion: 5D has better overall image quality but Cinestyle preset is much noisier and much more susceptible to banding. 5N is a bit more saturated and a tad sharper. Both cameras produce a nice image.
