Yes, 16-50 (2nd ex.) No, 50-135

My first 16-50 was missaligned.
Foreground, left - soft, right - sharp
Background, left - sharp, right - soft

It went to Japan for service. After over 2 months it came back with the same faults.
Managed to change it to a new one, - with dead SDM.
The third one works well except for a leakage during an 2 hour rain.

I guess the seal isn't 100% proof if you've got som small dust on the mating surfaces.

It took three days until it worked again!!!
