Do I have a bad copy of Sony E Sigma Lens ?
I purchased Sigma 30mm f1.4 DC DN C for my A6000 a few weeks ago and realized something is up when I take multiple shots. It appears that when I shoot continously, it has 2 to 3 slightly different exposures on each shot. Even though nothing moves - not the camera, subject, lighting, everything is same, except the exposures.
I tried with different mode, different aperture settings, different shutter speed, ISO, AWB, drive mode, focus mode, even metering, still the same results - few pictures with different exposures.
But when I tried on the kit lens, everything's fine.
Do I have a bad copy, or does the sigma lens do that?
