Best Canon Lens For Astrophotography: The Buying Guide

Not all lenses are capable of capturing wonderful images of the milky way. Everyone must agree that several critical factors must be considered before buying a lens for that. However, if you are interested in buying one, our review has your back.

Here, we bring some of the vital factors you need to consider before buying a lens for astrophotography. You should go through them before wasting your hard-earned money.

Focal length:

If you want to capture nightscape photos and landscapes of astronomical objects, you would usually go for a wide-angle lens. If you use an APS-C or cropping camera, 24mm focal length or less should be the best in the business. On the other hand, a focal length of 35mm or less produces the best result for full-frame cameras.

A wide-angle lens allows you to frame more area of the night sky by offering a larger field of view. It can collect more light from the larger sky that helps compromise to a small clear aperture.

A long shutter speed can result in blurring the stars on a wide-angle lens as they move continuously. However, a short focal length on a wide-angle lens allows for long shutter speeds with no star trails.

The smaller the focal length gets, the wider the angle becomes. With a relatively bigger frame, a wider-angle lens gets a certain amount of time before the earth rotates enough to start a trail of the stars across the frame. The time reduces as the focal length increases because of the shorter frames they offer.

Aperture:

Aperture controls how much light enters the sensor. A narrow aperture lens with a longer focal length doesn’t produce the best images with a shorter shutter speed to avoid star trailing. On the contrary, a wider aperture lens can use a shorter shutter speed and lower ISO to capture an image with less noise. That means lenses with wider aperture are better for astrophotography. But the lenses very often come with a great price tag. If you can buy one, that would be worthy enough.

Coma and Chromatic Aberration:

The best canon telephoto lens for astrophotography should have better control over coma and chromatic aberration. These are the most important factors for clicking the best images of the milky way. They refer to the minor distortion of light you get while capturing in low-light conditions.

The coma and chromatic aberration cause the stars to appear as slightly odd shapes. The phenomenon especially occurs towards the frame’s edge. If a lens can better suppress the phenomena with better chemical coating or premium quality glass, it will produce clearer images.

Manual Focus:

The feature enables you to adjust the focus, depending on your desire. Not all lenses offer the feature that allows the photographer to play with the focal length range. That’s how photographers’ individualism arises as they can customize the picture with the focus as their wishes.

Image Stabilization:

Most advanced camera lenses come with the feature to stabilize output, ignoring slightly shaky effects. When you are capturing photos on an uneven surface, there are high chances to get a blurry effect in the images. Image stabilization automatically reduces the effect and present sharper photos.

Prime or Zoom Lens:

Generalizing the best type of lens is difficult as it largely depends on what type of shots you are intended to take.

Prime lenses are broadly fixed focal length lenses that are great for landscape milky way photography shots. You can also include background features. Zoom lenses, on the other hand, provide you a range of focal lengths. They are tough to focus at infinity for both night sky and landscape photography.

Lenses with a focal range of 10 to 14mm can capture the whole milky way. Once you get one over 24mm or above, you may not get the full width of it.

Astrophotography Techniques

The idea of taking pictures of the night sky isn’t a new one. The alliance of scientists and photographers basically developed it. There are two traditional techniques used for astrophotography. The first one uses traditional DSLRs with tripods and lenses. The second one includes attaching your camera directly to the telescope.

Using lens and a Tripod: The simple and straightforward way makes it easy for all to go somewhere and capture beautiful sky photos. As the technique requires less equipment, it’s easy to travel with your bags using this one. The important thing is to choose a lens capable of taking bright images in dark conditions. Also, a wide-angle lens is well recommended to get a maximum field of view. Get the best camera for astrophotography and start on your way.

Attaching Camera to Telescope: A telescope has excellent magnifying power. Attaching your camera to the telescope can be a great option to capture night views. The technique is expensive because of using a telescope.

The process is also perfect for those who want a permanent setup rather than traveling to a place for astrophotography. You need to attach the camera to the telescope via an adapter. Different manufacturers adopt different ways to attach lenses to the camera body. So, it’s important to match the adapter with the camera’s mounting system.

Frequently Asked Question (FAQs)

what focal length is best for astrophotography?

Ideally, a wind angle lens is perfect for astrophotography. 24mm or shorter focal length will do good for APS-c cameras, and 35mm or shorter is good for full-frame cameras. However, sticking to 14-20mm is the best to get the best result.

what is optical image stabilization?

An optical image stabilization (OIS) is a mechanism used in most advanced camera lenses to stabilize the recorded image. OIS controls the image’s path through the lens onto the image sensor.

Telescope or lens for astrophotography?

You can use both telescope or only lens for capturing beautiful pictures. Using a telescope is expensive and better for a permanent setup. The other one is simple and travels friendly.

Verdict

In the world of photography, astrophotography may sound luxurious. It is perhaps because of the requirement of high-end camera lenses and additional kits. However, you can still take great pictures of the night sky using low-budget lenses. Just make sure the lenses are compatible with that. After reading our buying guide, we hope you will be able to buy the best canon lens for astrophotography for you.
