I have the A50/1.4, A50/1.7, A50/2 and A50/2.8 Macro. The A50/2 feels
a bit cheap, the A50/1.7 a bit less so, the f/1.4 and f/2.8 Macro
feel like high quality lenses. I hope the A50/1.2 has the same high
quality feel as the f/1.4 and f/2.8.
Performance-wise, the A50/2 is the poorest performer of the lot, wide
open and at f/4; even it at f/5.6 and beyond is darn nice. The others
are excellent virtually everywhere.

... right now I'm more concerned with the construction and feel
of the A50/1.2. I've been thinking of making some comparos between
the
50's myself. Just not have been feeling up to it lately.
