Best Lenses for Milky Way Photography: Canon Astrophotographers

Best Lenses for Night Photography: Canon Astrophotography

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.

    What is the best lens for canon 650d to capture the milky way, is it possible to capture it
    by this entry level camera?

    • John Strandberg February 16, 2018 / 2:18 pm

      Your camera will give you excellent results, perhaps better than you expected. For a nice versatile lens I like the Sigma 18-35mm. My favorite is the Rokinon 35mm f1.4 lens because I like a little smaller FOV to see more detail. I also use manual focus; in fact my Rokinon is an older manual focus only lens.

      Go forth and have fun!

    Hello… I am very new to photography and I am so confused with many selections of cameras and lenses.

    if I am going to buy just one camera and lens for travelling, street, landscape and astrophotography what would you recommend?

    Thank you

      I personally like Canons — almost any of their DSLRs, you don’t have to spend huge amounts of money to get a great body. If I could pick only one lens, it would be the Tamron AF 24-70mm f 2.8 lens. A great all-around lens and incredibly good at astrophotography.
