Is the samyang af 24 70mm f 2 8 fe good for astrophotography?

I don't have an astrophotography guide on the site yet, so I can't give you a firm verdict on night sky work with this lens. What I can tell you is what it is: a full-frame 24-70mm f/2.8 zoom with autofocus and no stabilisation. The wide end and f/2.8 aperture are the parts that matter most for stars, because a wide aperture gathers more light in dim conditions, as explained in the lenses guide. Without stabilisation, you'll want a tripod for long exposures.

For framing big skies over a landscape, the landscape page is a good place to start.
