Is the panasonic leica dg 12 60mm f 2 8 4 good for astrophotography?
I haven't written anything on this site about using this lens for astrophotography, so I can't tell you whether it's good for it. What the page does say: it's a stabilised Micro Four Thirds zoom, 12-60mm at f/2.8-4, and it gets darker as you zoom in. Those are the figures that matter most for night work, so check them against what you'd need for stars.
If you're looking at astro specifically, the OM System OM-3 Astro is one of the Micro Four Thirds bodies this lens fits, and it's worth a look. For general lens advice, the lenses guide covers how to choose glass for different subjects.
