Top Choices

Best canon lens for astrophotography

Selections that seem to perform well for astronomical imaging include:

1. Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens

If all you need is to get super-wide shots of the night sky and other landscapes without burning a hole in your pocket, Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens could be worth considering.

It is one of the lightest Canon lenses designed to work with EOS crop sensor cameras.

The glass elements it packs, which include UD, aspherical, and the larger-diameter element ensure that it gets remarkable shots of the sky without aberration and distortion problems.

Canon EF-S 10-18mm f/4.5-5.6 IS STM Lens also comes with image stabilization, which can help when using a tripod.

As for the level of freedom, you get a little thanks to its full-time manual focus. 

However, as a low-to-mid-priced lens, you really don’t want to expect a lot from it.

But if you are a beginner astrophotographer or someone into it for sheer fun, Canon EF-S 10-18mm f/4.5-5.6 is still a good deal.


  • Optical image stabilizer
  • 10-18mm focal length
  • Nearest focusing distance
  • Ultra-low dispersion element
  • Full-time manual focus


  • Attractive price point
  • Convenient image stabilization feature

  • Extremely lightweight


  • Struggles in low-light situations

2. Canon RF 15-35mm f/2.8L IS USM

Canon RF 15-35mm is one of Canon’s incredibly well-built lenses for night photography.

With a focal range of 15-35mm and Nano Ultrasonic AF, this fisheye lens nails amazing views of the celestial events.

Glorious details of the stars are visible at 35mm but with a slight drop in sharpness-something that doesn’t bug that much.

Plus, you can still crop images, an ability most lenses lack.  

Design-wise, this lens is beautiful and less cluttered allowing for a fuss-free operation.

Though unnecessary for astrophotography, it still bears 5 stops of optical stabilization that can be further stretched to 8 stops with a compatible RF body. 

As a versatile tool for astrophotography, architecture, landscape, and other types of photography, Canon RF 15-35mm is totally worth having.


  • L-series glass

3. Canon EF 17-40MM F/4L

Canon EF 17-40mm F/4L is another gem that takes epic star photographs.

The super Ultra-low Dispersion glass element together with the three Aspherical lens elements ensure your shooting experience will be immersive.  

Like other Canon lenses, this one too sports superior coatings to allow the use of digital SLRs.

On top of that, it has a full-time manual focus to override automatic settings. Courtesy of the robust design, the kit formidably withstands the rigors of harsh weather.

Besides astrophotography, Canon EF 17-40MM F/4L is also perfect for wedding and nature photography.

Furthermore, its focal range of 17-40mm might reduce the number of lenses you would need to carry along.

Does that sound like a sweet deal? If yes, then this lens might be a great grab.

4. Canon EF 50mm F/1.2L USM

Canon EF 50mm F/1.2L USM is a versatile, ultra-fast lens that could come in handy for practically any photography situation.

It’s therefore the one gear you should have if you’ll be shooting something else later beside the stars.

The lens boasts spectra coating whose purpose is to tone down flare and ghosting. As such, you can expect it to capture sharper details both during the day and night time.

Also, it comes with a full-time manual focus for the freedom to pick your own settings.

There are a few setbacks with the Canon EF 50mm F/1.2L USM. First, its design is bulky and that can be discomforting.

Secondly, the large make adds more weight to your gear bag. Thankfully, Canon EF 50mm F/1.8 serves as a better replacement as it is both cheaper and weightless.

5. Canon EF 16-35mm f/2.8L III USM

Canon EF 16-35mm f/2.8L III USM is dependable on the true essence of the word itself.

With a focal distance between 16 and 35, this is another versatile workhorse that you can carry along for activities that stride beyond astrophotography.

Boasting a grandiose f2.8 wide aperture, and Subwavelength coating( SWC), this lens will get you stunning images that make you go “uh-huh.”

But before we talk about its astronomical price tag (which is totally worth it), note that the lens is also designed to resist dust, water, and other harsh conditions.

As one of Canon’s best wide-angle lens, EF 16-35mm f/2.8L features improved optics to do away with the sharpness that mostly appear on the edges of images.

So in exchange for such remarkable clarity, this lens comes at a price that many would deem expensive.

But if you are a professional photographer, this rig is worth splashing money on.
