This is the hardest I've had to push the ISO on the 5D3 so far, and I'm pleasantly impressed. This isn't meant to inspire pixel peeping (sorry, no 100% crops
), but rather to show what's possible with clean ISO 3200-6400 images. I know that's not that high by today's standards, but suffice it to say that I would have never attempted shots like this prior to picking up a 5D3. I f'd up and underexposed the images by 1/2 to 1 stops, but the images cleaned up nicely in Lightroom, and noise wise, are plenty nice enough for a two-page magazine spread.
ISO 3200, exposure pulled 1 stop
ISO 6400, exposure pulled 1/2 stop. Not enough motion blur in this one for my liking. I really didn't notice much difference in noise between ISO 3200 and 6400.
ISO 3200, exposure pulled 1/2 stop. Good sense of motion, but too soft to run large in print. Oh well, maybe next time.
A few notes:
1) The AF system is a beast. It was very dark, and the AF locked on effortlessly in AI Servo. On the other hand, the the black AF points are invisible at night when locked onto a black subject. I had to keep hitting the AF selection button to turn the points red in order to ensure they were positioned on the subject correctly.
2) For this set, the in-camera jpeg processing was quite lacking. I shot both raw and jpeg, and the jpegs yielded more noise and less detail than the raws. That's no surprise, but it becomes very evident at 3200-plus ISO. In better-lit scenes, IMHO, the jpegs render adequate detail and quality for my needs up to 3200. For stuff like this, it's raw all the way.
