For the tech-heads, I reckon the 02 is a little wider than than the DA*16-50. Here are three shots taken from exactly the same spot: I reckon with the slightly squarer format of the Q7, the 02 gets as much horizontally as the DA15, and more vertically.
Although I have corrected the purple fringing in these shots, the 02 fared better than the two far more expensive lenses.
Its central resolution is nowhere near as good as the others, possibly in part due to diffraction @ f/8.0, but its edge sharpness was much better than the DA15 (which is notorious for this problem, but I wonder if my copy is worse than average....)
DA*16-50 @ 16 02 @ 5 DA15
Oh yeah, it would seem the hood for the 02 was designed for the angle of view of the original Q. With the Q7 it cuts off the corners significantly
02 @ 5 with hood!
