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. I’m kind of new with photography so I’m actually quite confused on what kind of wide lens i should use to photograph the milky way. I have a canon 70d (crop sensor cam). I don’t really know what’s best and compatible wide lens for my cam. Any advice?

  2. I just purchased the “Rokinon 16M-C 16mm f/2.0 Aspherical Wide Angle Lens for Canon EF Cameras” and it doesn’t fit on my Canon EOS Rebel t1i. Is there an adapter I can use? I’m very distraught about this as there’s finally a clear sky tonight and I can’t even go out and try it 🙁

  3. I just purchased a canon rebel 6Ti or 750D, I am super new to all this and im wondering if I can take good star pictures with this camera and if so what lense should I use?? Thank you!!

    1. I would say “decent” pictures. Look me up on Instagram for some examples. They were all with either the T5i or the T6i. There are many factors you can change to improve your shots. In my opinion the shorter the focal length and the wider the max aperture, the better, at least for single exposure shots. You can also stack several photos for better results, though the technique is very involved and a bit technical. Search for DeepSkyStacker, at least the program is free, though it does require a Windows OS.

    2. Oh BTW I just purchased a Tokina 11-16mm 2.8, though I have gotten pictures good enough for Instagram with the 18-55mm 3.5 kit lens.

  4. I’m curious why I see no mention of the Canon 16-35mm f/2.8 ii anywhere? It’s a great lens and reasonably fast. Is it the price that excludes it from consideration, or is there some other reason?

  5. Hi. I currently shoot on a Canon 80D with a Tokina 11-16. I was starting to think about purchasing the Sigma 18-35 Art just because of all the good things I’ve heard. My only issue is I have a Canon 24-105 F4L, would you say the upgrade of the Sigma 18-35 for night sky specific shots over the Tokina is significant enough to justify the purchase.

    If the Sigma doesn’t have a drastic leg up over the Tokina, I may stay put.

    Thanks.

  6. Just bought a Rokinon 16mm f/2 using your Amazon link, thanks for the lessons man. I am just starting astrophotography and I appreciate what you do.

    1. Thank you for giving all these options, now I just need to decide if I want to go big and buy your #1 or if it would be worth it to buy one of the less expensive options and use the left over money on accessories. I’ll have to dive deep into your reviews for my answer.

      Amazing site and thank you for all the info you provide
