Guys help me out. I can see lot of good reviews about APO DG but I cannot find any review on DG OS. In India, APO DG costs INR 11500 (approx USD 244) compared to DG OS (i.e without APO and not the f2.8 one) at INR 20500 (approx (USD 436). Which is better on IQ and sharpness?
oh yes

It could have just been me again.
