Can Any Lens Work for Astrophotography?

No, all lenses do not work for astrophotography as it needs specific features. Admittedly, the photography tool kit that brands put out does not have any particular astrophotography lenses. But that does not mean that you can use any lens that you want for astrophotography. 

The shutter of aperture has to be quick to make the images brighter and sharper. The aperture width requirements for astrophotography are different, as well. Only the lenses that have an aperture width between f/2.8 and f/5.6 can prove useful for astrophotography. 

So, you have to buy a lens with certain specifications if you want to practice astrophotography.

Why Did These Astrophotography Lenses Make Our List?

There are so many lenses on the market that claim to be good for astrophotography. But we do not like all of them as they are just not good enough. So, we have brought you some features that make us like our favorite models so much.

High Optical Performance

Optical performance covers a lot of aspects of a lens, ranging from the clarity of the image to focus on the subject. The lenses on this list come with a high optical performance, which improves the overall picture quality. They adapt well to low light conditions and even the dark, making them even better for astrophotography.

Greater Brightness

Brightness is something that becomes a major problem in dark conditions. And the night sky is not easy to capture without enough light in the lens. As these lenses have better brightness and light adjustment, we like these a lot. 

Lesser Shutter Duration

Shutter duration also has a huge effect on the image that you take from your lens. The less the shutter duration is, the sharper the focus of the camera. Stars are just tiny pinpricks in the dark sky, so it is hard to focus on them. This is why you need lenses with very fast shutter speed to have fun with astrophotography.

Aspects to Consider Before Buying

Astrophotography lenses have a great variety on the market, making it difficult to choose one. The competition is quite high, and the advertisements can be misleading sometimes too. So, you have to be very cautious while buying a new lens for astrophotography. Here are some of the aspects that you have to consider before making a purchase.

Focal Length

The focal length of a lens is its most important feature as it limits the range of focus. For astrophotography, you need greater focal length as the objects are very far away. Lenses that offer a range of focal lengths rather than a single focal length are better.

Aperture Width

The aperture width of a lens needs consideration as well since it affects the clarity and quality of an image. The aperture should be wide enough to let in the maximum light in the dark too. This also affects the low light performance, so keep it in mind while buying a lens.

Manual Focus

Another important aspect of an astrophotography lens is its focus. You should be able to control the focus manually as not all stars need to be focused. This causes a problem with auto-focus, so make sure that the lens has a manual focus option. 

How to Use Astrophotography Lenses

Using an astrophotography lens is not a big deal if you know how to do it. You also need to have the right equipment to photograph the night sky. With that said, here are some steps that you have to follow in order to use an astrophotography lens.

  1. Begin by choosing a position for photography and set the camera on a tripod. The steadier the camera, the better the shot will be.

  2. Set your camera in manual focus mode and open the aperture of the lens to its maximum width.

  3. Then open the brightness of your lens to let the most light into the camera. You might even need to use a flashlight to make the sky look brighter. 

  4. Shut off the auto-focus and then manually focus on the brightest star. 

  5. The focal length needs to be at the perfect spot. So, adjust the focal length at a point from where you can focus on the object easily.

  6. Then take shots while keeping the focus object near the center of field. This will make the image more realistic and attractive.

The following video provides a much better overview of how to use such a lens. 


Summing it all up, you need particular lenses for astrophotography as it is slightly trickier than others. The specifications of the lens depend on the kind of subject that you like as well. The aperture has to be in line with the object that you focus on. So, be careful when it comes to choosing a lens as it affects your photography and image quality.
