Can Any Lens Be Used For Astrophotography?

There are a number of characteristics that contribute to deciding the right camera lens for astrophotography. The capability and quality of the lens are quite important to determine whether it can be employed for astrophotography and crafting flawless Milky Way nightscapes.

There are varieties of lenses that are being employed to create some worthy shots in astrophotography; however, not all of them are efficient enough to provide the best results. This section has summarized the attributes of a lens suitable for astrophotography.

Wide-Angle Lens

The most preferred lens for astrophotography is a wide-angle as it offers a larger field of view. This type of lens helps you in capturing more of the Milky Way with its ability to collect light from a larger portion of the sky. This trait, in combination with a wide aperture, provides a balance in color consistency and brightness.

Short Focal Length

In order to achieve fast and non-tracked photography, generally, a shorter focal length is employed. You might use a 24mm or shorter lens for APS-C cameras or a 35mm lens for a full-frame body. A shorter focal length is quite effective in avoiding stars trails from arising due to the Earth's rotation and ultimately provides sharp images by virtue of the long shutter speed.

What Should I Look For When Buying a Lens For Astrophotography?

The decision can be extremely daunting whenever you come across a plethora of options to choose from. You will find a variety of lenses, and each of them would be great in the best way possible. In order to help you get the perfect one to fulfill your demands, we have summarized a couple of essential features that must not be overlooked while making a purchase.

Quality Construction

This is one of the most significant features of a great lens. Whenever you pick a model, make sure it is composed of high-quality products and also comes from a reputed brand. These brands have a proven history of providing high-end products, which are likely to last for a long time when compared to the models manufactured from cheaper materials.


Although lenses for astrophotography can be expensive, it is still possible to get a model with all the essential features that easily fits your budget. However, you are advised to always go for quality products in order to make a worthy investment.

Weather-Proof Design

Another important feature of a quality lens is its weather-resistant capability. The model must be capable of enduring harsh weather conditions in the field without compromising on superior performance. This way, you can take it along for outdoor photography without any hesitance.

Ease of Use

A lens that is easy to handle saves the user from a lot of confusion during the photography session. Therefore, you must look for a model that requires the least manual settings. This is especially important for people who are new to this type of photography.

Benefits of Investing in a Quality Lens

A wide-angle lens with an effective aperture can cost you quite a lot. Therefore, whenever you intend to purchase a quality camera, you have to spend a great deal of money. Although this might get heavy on your pocket, there are multiple benefits associated with investing in a quality lens that make the investment worth it.


One of the significant advantages of a quality lens is that it is meant to last in the long run. Since it is from a reputed brand and, therefore, made from high-quality materials, it is likely to serve the user for a longer period of time. Moreover, there would be no additional expenditures for repair and replacement.

Stunning Images

Another advantage of combining a quality lens with the right body is that you get to have flawless images every time. A lens equipped with great focal length and wide aperture allows extended transmission of light and, therefore, results in bright and clear pictures even in dim lighting.

Similarly, chromatic aberration control ensures distortion-free pictures to a great extent.

Value to Your Bucks

Since not everybody is capable of spending tons of money every time they upgrade their lens, the decision should be made wisely. A great lens comes with some exceptional features that combine to provide better and clearer pictures, regardless of any lighting conditions.

What Do I Need to Know Before Buying?

Before investing in a quality lens, you are always advised to take some essential factors into consideration. This way, you will surely end up having the right model for your requirements that will not only be superior in performance but also bring value to your money.

Focal Length

As discussed above, a wide-angle lens is the most preferred choice to achieve high-end astrophotography. The major reason includes a number of options to choose from when it comes to the field of view. In simpler words, you get to choose how much sky you want to capture in one frame.

You are recommended to go for a shorter focal length as it provides longer shutter speed, and ultimately, you get to have sharp images of stars without getting a trailing effect.


Another important factor to consider is the aperture of a lens as it directly contributes to the amount of light that enters it. A wider aperture with short shutter speed lets you capture high-quality images without any noise or distortion.

Chromatic Aberration

The most important factor that really affects the images during astrophotography is the chromatic aberration. It is strongly advised to always pick a lens that comes with a high level of chromatic aberration control. This will eliminate the chances of slight distortions of light points whenever you are shooting in low light conditions.


With this, we come to the end of this review. A wide-angle lens with a wide aperture can help you ace astrophotography. You are recommended to always look for major features whenever you are in the market to make a purchase in order to avoid any regret in the future. Hopefully, this review of our best models has helped you in finding the right one you are looking for!
