Is the leica vario elmarit sl 24 90mm f 2 8 4 asph good for astrophotography?

The site doesn't have a dedicated astrophotography guide, so this is a judgement from the specs. The Leica Vario-Elmarit-SL 24-90mm f/2.8-4 ASPH is a sensible choice for night skies at its wide end. At 24mm and f/2.8 it gathers enough light for the Milky Way, and the stabilisation helps when you're shooting handheld in the dark.

It has drawbacks, though. It only reaches f/2.8 at 24mm and drops to f/4 by 90mm, so it gets darker as you zoom in. It's also large and heavy. Stay at the wide end for stars.

If you want f/2.8 across the whole range, look at the Leica Vario-Elmarit-SL 24-70mm f/2.8 ASPH. For more on wide zooms for big skies, see the landscape lens notes.
