Best Lenses for Milky Way Photography: Canon Astrophotographers

The most common question asked on Lonely Speck answered for Canon shooters!

What is the best lens for astrophotography? The one that collects the most light.

Below is a list of the highest scoring lenses for untracked nightscape photography and astrophotography. The score is a direct representation of light gathering capabilities based on the formula:

Score = (aperture area) × (angular area) × (suggested shutter speed)

Where the shutter speed is the longest suggested shutter speed in seconds based on the “500 Rule” (500/focal length). Aperture area is the surface area calculation of the clear aperture of the lens and the angular area is the angular field of view in square radians. This score is a mathematical calculation based purely on some simple physics. It doesn’t account for other considerations like the lens’s build quality or optical aberrations but it’s a good gauge of overall light gathering capability.  You can also see the complete list of scores here, complete with calculations and further explanation.

All of the lenses listed here are my personal suggestions for photographers looking to get the absolute best astrophotography results with their camera. If using the given camera mount, these are the lenses that I would use. Most of these lenses are manual focus lenses by Rokinon which also tend to be much more affordable than their autofocus Canon counterparts. Additionally, most of the Rokinon lenses are sharper and tend to exhibit less coma aberration than their Canon counterparts. If you’re willing to learn how to use manual focus, Rokinon lenses are spectacular performers.

  1. hello
    I like to use samy 24mmf1,4 on fuji apsc what you think good way if use lens with lens tubo?

    Thanks Gabor

  2. hello i m new to astro-photography, i have canon eos 7d with lens 18-55mm (.25/0.8ft) EFS and 75-300 EF (1.5/4.9ft) EF lenses can i do such photography using these lens. I need to know the answers because i have been trying to take pictures of stars, i could never snap a milkyway arm like you guys do.

    1. Neither lens is optimal for Astrophotography, however, you can still get decent photos of the stars if you keep your shutter speed below 15 seconds (at 18mm) wide open. Depending on your editing skills, I would start your ISO at 3200. If you can lower your ISO, you can bring the stars out in post.

      Another option would be to look for a used Rokinon 14mm lens.

  3. Hi Ian,

    Love your website! I am getting ready to purchase the Sigma 24mm 1.4 Art lens and noticed that your were planning to do a review of this lens for astrophotography purposes. I would be very interested in this review if you can direct me to where it could be located.

  4. Not sure if this comment is feedback or a question.

    I got the Rokinon 16mm f/2.0 ( sold as a Samyang here). I am mostly happy, as it it is FAST.

    However the quite some distortions in the corners of my pictures. Stars become a lengthy streak pointing towards the center of the picture. Higher apertures alleviate the issue but are not a helpful for night photography.

    Does anyone have the same experience or maybe a recommendation? Or did I just happen to get an faulty one?

  5. Hi there,
    This is very informative.
    I’m looking for the best wide angle lens on a budget.
    I have a Canon 5d Mark IV full frame. I’d like to use the lens for landscapes, but also for night stars and Milky Way (and plan to try Northern Lights in the next year or two). I have a trip to Monument Valley coming up.
    I was looking at the original Canon 16-35mm f/2.8, but it doesn’t seem to be a best bet, and the Tokinas you recommend aren’t for full frame.

    Suggestions for the best lens to serve multiple functions at less than $800?
    Thanks

    1. Sigma is coming out with a new 14mm f/1.8
      You should look into that this year. All of their ART lenses have been nothing short of spectacular.
