Get the Sony FE 12-24mm f/2.8 GM lens. This lens, though incredibly expensive, has proven its worth in astrophotography. Its edge-to-edge sharpness and lack of coma or chromatic aberrations, even at 12mm, allow for stunning Milky Way captures. The build quality is exceptional; I accidentally dropped it once, and despite a dent in the metal lens hood, it still performs flawlessly. The extreme wide-angle capability enables you to capture expansive night sky scenes. For serious astrophotographers, this lens is a game-changer, delivering unparalleled image quality and durability.

The Sony FE 16-35mm f/2.8 GM II is another fantastic lens for astrophotography. Its versatile zoom range from ultra-wide to wide-angle allows you to experiment with various perspectives of the night sky. The constant f/2.8 aperture ensures you get plenty of light, and the G Master optics deliver incredible clarity and contrast. It’s a bit heavy, but the build quality is top-notch, and it performs exceptionally well in low-light conditions.
