Hi guys,
a couple of days ago I was at a Robotics Competition at the Stanford University, held within a campus building (artificial lights, not too intense). I had my Q with me, with both the primes.
I was documenting the event (pretty funny, indeed) and a pro photog that was also there with two big'n'heavy Nikon FF guns approached me asking about the Q. I handed it to him, and he was generally impressed by the Q feel (perhaps just to be nice, though).
"Do you really don't need any flash here? with that tiny thing?", he asked. "Well, I'll let you see by yourself. Gimme your email and I'll send you some samples."
So I did, and he answered with surprise and appreciation for the image quality. He didn't pointed out his own results, though.
Would you like, you could find the report here (I'm sorry, though, it's in Italian):
