Lens recommendation, 1X-1XX 2.8 ?
I have and a77 and am using Sony 16-50, Sigma 50-150, Sigma 50mm 1.4, and Sony 70-400 and love the combination.
I did have to send the 50 1.4 and 50-150 back to Sigma to have calibrated because they share the same Lens ID as each other. One needed +2 lens compensation, and the other needed -6, so there was no happy medium. Now they're both perfect.
