How to choose
Good to know
What is the best focal length for astrophotography?
For most night sky shots, a 14mm to 24mm lens is best. It provides a wide view and allows longer exposures without star trails.
Is a fast lens necessary for astrophotography?
Yes, a faster lens (f/2.8 or wider) lets in more light, enabling you to use a lower ISO and shorter shutter speed, which reduces noise and star trails.
Can I use a kit lens for astrophotography?
Kit lenses typically have a maximum aperture of f/3.5 or f/5.6, which may not gather enough light. You can still capture basic shots, but results will be less impressive.
Should I choose a prime or zoom lens?
Prime lenses generally have wider apertures and sharper optics, making them better for astrophotography. Zooms offer versatility but often have smaller apertures.
How do I focus a lens in the dark?
Switch to manual focus and use live view to zoom in on a bright star. Rotate the focus ring until the star appears as small and point-like as possible.
What is coma and how does it affect my photos?
Coma is an optical aberration that makes stars look like comets at the edges of the frame. Lenses with low coma produce sharp, round stars.
Are full-frame lenses better for astrophotography?
Full-frame lenses offer wider fields of view and often better light transmission. They are ideal if you use a full-frame camera.
Can I use a lens with a tripod for astrophotography?
Absolutely. A sturdy tripod is essential to keep your camera steady during long exposures. Your lens should be mounted securely.
What is the rule of 500 for astrophotography?
The rule of 500 helps avoid star trails: divide 500 by your focal length (full-frame equivalent) to get the maximum shutter speed in seconds.
How do I choose between Sony, Canon, and Nikon lenses?
Consider your camera’s mount. Each brand has its own mount system, so select a lens compatible with your camera body.
Our take
For the best balance of performance and price, choose the Rokinon 14mm f/2.8. If you own a Sony full-frame camera and want the ultimate in sharpness and speed, invest in the Sony FE 14mm f/1.8 GM. For those on APS-C, the Tokina 11-16mm f/2.8 offers great versatility. No matter your choice, a wide, fast lens will transform your night photography.
