For Milky Way photography, I would start with the Nikon 20mm f/1.8G if your camera uses Nikon F mount: its bright aperture gives it an advantage for gathering starlight, while 20mm is wide without making foreground choices feel as demanding as they can with 14mm. Sony APS-C shooters have a different standout in the TTArtisan 10mm f/2, which pairs a broad view with a faster aperture than the f/2.8 options here. For Canon EF bodies, the Samyang 14mm f/2.8 offers expansive framing and an AE chip for metering.

Those strengths come with real compromises. Aperture, focal length, sensor format, mount compatibility, manual focus, and carrying weight all shape the choice; a lens that looks ideal on paper may not fit your camera or your preferred foreground composition. I rank these picks by their usefulness for night-sky framing and low-light work, then account for how practical they are for the specific camera system they support.

Key Takeaways
- Nikon F-mount users: I rank the Nikon 20mm first for its f/1.8 aperture, the brightest maximum aperture in this group.
- Sony APS-C users: The TTArtisan 10mm f/2 combines a very wide view with a fast aperture, but it is a manual-focus crop-format lens.
- Canon EF users: The Samyang 14mm has a 115.7-degree view and a built-in AE chip; its manual focusing is a deliberate night-shooting task.
- Canon RF users: The RF16mm f/2.8 is the light, compact system-specific choice here, though the supplied specifications do not state its angle of view.
- Framing tradeoff: I favor 14mm and 10mm when a large sweep of sky matters most, while the 20mm gives foregrounds and sky a less extreme balance.

More Details on Our Top Picks
Nikon AF-S FX NIKKOR 20mm f/1.8G ED Prime Lens
I put the Nikon first because its f/1.8 maximum aperture is the fastest among these five lenses. That gives Nikon F-mount photographers more light-gathering headroom than the f/2 and f/2.8 choices, which can help when balancing shutter time, ISO, and star shape. Its 20mm focal length is wide enough for a broad sky-and-landscape composition, but it does not stretch the scene as dramatically as either 14mm option or the TTArtisan 10mm.
The 94-degree angle of view makes this a more measured wide-field pick than the ultra-wide alternatives. That can help when a foreground feature should remain a substantial part of the frame, though photographers seeking the largest possible sweep of sky may prefer the 14mm Samyang or Rokinon. The listed ED and aspherical elements and Nano Crystal Coat address chromatic aberration and flare, both relevant when bright stars and stray light sit in the frame. Those listed features are useful, but the supplied details do not quantify corner sharpness for stars.
Autofocus with Nikon’s Silent Wave Motor is available, but for star placement I would plan to focus manually and confirm focus with magnified live view. It has no image stabilization, which is not a major loss on a locked tripod, but it does not help when the lens is used handheld for other scenes. Compared with the Canon RF16, this is the brighter option on paper; compared with the TTArtisan, it offers Nikon FX and DX compatibility rather than a Sony APS-C-only fit.
Pros:- The f/1.8 maximum aperture is the fastest in this lineup.
- 20mm framing balances broad sky coverage with substantial foreground detail.
- FX and DX compatibility suits two Nikon sensor formats.
- ED glass, aspherical elements, and Nano Crystal Coat address flare and color fringing.
Cons:- Its 94-degree view is narrower than the listed 14mm and APS-C 10mm options.
- No image stabilization is included.
- The Nikon F mount limits use to compatible camera bodies.
Best for: Nikon F-mount photographers who want the brightest listed aperture here and prefer a wide but not extremely stretched perspective.
Not ideal for: Photographers who need a very expansive 14mm-or-wider full-frame view, stabilization, or a lens for a camera outside Nikon F mount.
- Focal length:20mm
- Maximum aperture:f/1.8
- Angle of view:94 degrees
- Mount:Nikon F
- Format compatibility:FX and DX
- Focus:Autofocus, Silent Wave Motor
- Minimum focus distance:0.66 ft (0.2 m)
- Filter size:77mm
Our verdict“For Nikon F-mount night-sky photographers, I rank this first for its f/1.8 aperture and versatile 20mm framing.”
TTArtisan 10mm F2 APS-C Ultra-Wide Camera Lens for Sony E-Mount
For a Sony E-mount APS-C camera, the TTArtisan stands apart with a 10mm focal length and f/2 aperture. Its 105-degree view is designed to fit a broad portion of the night sky into one frame, and the fast aperture is stronger on paper than the f/2.8 14mm and Canon RF16 options. This combination makes it the most expansive listed choice for its intended sensor format, though focal lengths should not be compared without accounting for the different sensor sizes.
The major boundary is clear: this lens is made for APS-C, not full-frame cameras. It also uses manual focus, which is common for night-sky shooting but requires care when focusing on stars. I would use magnified live view and check focus after any adjustment rather than relying on the focus ring position alone. Compared with the Nikon 20mm, the TTArtisan is much wider in its intended APS-C system, while the Nikon brings a brighter f/1.8 aperture and FX/DX compatibility.
The supplied description claims nearly zero distortion and notes a 72mm filter holder, which offers a practical way to use compatible filters for daytime landscapes. Its eight-blade diaphragm is also associated with an eight-spike starburst effect around point light sources, though that effect is usually not the main priority for Milky Way frames. There is no stabilization, and the available information does not give a weight or star-corner performance figures. I would choose it for Sony APS-C sky coverage, not as a universal lens for mixed full-frame systems.
Pros:- 10mm focal length gives an expansive perspective on its APS-C format.
- The f/2 maximum aperture is faster than the f/2.8 options here.
- Includes a 72mm filter holder for compatible filters.
- The supplied description notes nearly zero distortion.
Cons:- Designed for APS-C rather than full-frame cameras.
- Manual focus takes deliberate setup and checking at night.
- No image stabilization is listed.
Best for: Sony E-mount APS-C owners who want a very wide field and a fast f/2 aperture in a manual-focus prime.
Not ideal for: Full-frame Sony users, photographers who require autofocus, or buyers who want one lens to move between APS-C and full-frame bodies.
- Focal length:10mm
- Maximum aperture:f/2
- Minimum aperture:f/16
- Angle of view:105 degrees
- Format:APS-C
- Mount:Sony E
- Focus:Manual
- Filter size:72mm
Our verdict“I recommend the TTArtisan to Sony APS-C shooters who value a broad sky view and f/2 more than autofocus or full-frame compatibility.”
Canon RF16mm F2.8 STM Lens
The Canon RF16mm is the most straightforward pick here for an RF camera owner who prizes a compact kit. Its lightweight, compact design makes it easier to carry to a dark-sky location than the listed Rokinon, which weighs 900g. The f/2.8 maximum aperture is suitable for night-sky work, but it cannot match the Nikon’s f/1.8 or the TTArtisan’s f/2 on aperture alone. The fixed 16mm focal length is a simple, wide-field setup rather than a flexible zoom range.
Canon’s RF mount and full-frame compatibility make system fit its strongest advantage over the EF-mount 14mm pair. Its STM stepping motor provides smooth, quiet autofocus, useful for video and general photography, but autofocus is less central when focusing on stars. I would expect to set focus carefully by hand for Milky Way frames. The supplied specifications do not state the angle of view, so I would avoid choosing it based on a direct field-width comparison with the 14mm lenses.
This is not the aperture leader, and the description does not provide astrophotography-specific information about corner rendering or distortion. That leaves a tradeoff: the RF16 is the portable native-mount option, while the Nikon wins for maximum aperture and the Samyang offers a wider stated angle of view for Canon EF DSLRs. Buyers who already own RF bodies and want one small wide lens for night skies plus everyday scenes may find its role clear; those chasing maximum sky coverage should compare the framing they need before choosing.
Pros:- Compact, lightweight construction suits travel and night walks.
- The f/2.8 aperture provides a usable wide-aperture option for night skies.
- Native RF mount and full-frame compatibility fit Canon RF bodies.
- STM autofocus is smooth and quiet for video use.
Cons:- Fixed 16mm focal length offers no zoom flexibility.
- The f/2.8 aperture is slower than the Nikon f/1.8 and TTArtisan f/2.
- Supplied specifications do not state the angle of view or star-corner performance.
Best for: Canon RF camera owners who want a compact, lightweight wide prime for night-sky and general photography.
Not ideal for: Photographers who need the fastest aperture in this group, a stated 14mm-class angle of view, or zoom flexibility.
- Focal length:16mm
- Maximum aperture:f/2.8
- Mount:Canon RF
- Format compatibility:Full-frame
- Focus motor:Stepping motor (STM)
- Minimum focus distance:5.11 inches
- Maximum magnification:0.26x
Our verdict“I would pick the RF16 for a small Canon RF kit, not for the widest stated view or the brightest aperture in this comparison.”
Samyang 14mm f/2.8 IF ED UMC Ultra Wide Angle Lens for Canon EF
For Canon EF photographers who want a particularly broad field, the Samyang’s 14mm focal length and 115.7-degree angle of view make it a strong fit for sweeping sky-and-landscape compositions. It gathers light at f/2.8, matching the Canon RF16 and Rokinon 14mm but trailing the faster Nikon and TTArtisan. Compared with the Nikon’s 20mm framing, this lens places more sky and foreground in the same composition, which can be helpful when the Milky Way arches over a strong landscape feature.
Its manual-focus design asks for precise setup, but star photography often rewards manual focus once it is set carefully. A built-in AE chip is listed for accurate automatic exposure metering on Canon DSLRs, a useful distinction from the Rokinon details supplied here. Metering support does not replace manual focus, and it does not make the lens weather-resistant. The included petal-type hood can help reduce flare and protect the front of the lens, while hybrid aspherical elements and multi-coating are specified to reduce distortion and chromatic aberration.
I rank it above the Rokinon EF 14mm because the supplied information notes the Canon metering chip and does not list a heavy body weight; I am not treating that as proof of superior optical performance. Both are manual-focus 14mm f/2.8 options for EF mount, so I would compare their handling and confirm compatibility with the specific camera. Against the compact RF16, the Samyang gives a wider stated angle but is less convenient for anyone who wants native RF mounting and autofocus.
Pros:- 115.7-degree angle of view suits broad sky-and-landscape compositions.
- The built-in AE chip supports accurate automatic exposure metering on Canon DSLRs.
- Hybrid aspherical elements and multi-coating are specified to reduce distortion and chromatic aberration.
- Includes a petal-type hood.
Cons:- Manual focus requires careful setup for star sharpness.
- No image stabilization is listed.
- Not water-resistant.
Best for: Canon EF DSLR users who want a 14mm field of view, f/2.8 aperture, and a listed metering chip.
Not ideal for: Photographers who need autofocus, weather resistance, image stabilization, or a native Canon RF lens.
- Focal length:14mm
- Maximum aperture:f/2.8
- Minimum aperture:f/22
- Angle of view:115.7 degrees
- Mount:Canon EF
- Focus:Manual
- Minimum focus distance:10.8 inches (28 cm)
- Diaphragm blades:8
Our verdict“For Canon EF bodies, I favor this Samyang when a very wide frame and the listed metering chip matter more than autofocus.”
Rokinon FE14M-C 14mm f/2.8 Ultra Wide Lens for Canon EF Mount
The Rokinon earns a place as another Canon EF 14mm f/2.8 choice for photographers who want a wide, manual-focus prime. Its stated 115.7-degree angle of view matches the Samyang’s listed field, making both attractive for fitting the Milky Way and a foreground into one frame. The f/2.8 aperture is useful, although the Nikon f/1.8 and TTArtisan f/2 have a brighter maximum aperture for low-light work. I place the Rokinon below the Samyang because its supplied information lists fewer Canon-specific metering details and gives a substantial 900g weight.
That 900g listed weight is the most visible drawback for photographers walking to remote locations or packing a small kit. The built-in petal hood and manual focus suit a fixed night setup, where autofocus is not essential, but buyers should be comfortable checking focus precisely. Its optical construction is listed as 14 elements in 10 groups with aspherical elements; the description claims sharp, distortion-free images, but it does not supply measurements for star rendering near the frame edges.
Compared with the Samyang, the Rokinon offers a similar stated focal length, aperture, field of view, and mount, so I would not frame this as a clearly different optical category. The practical distinction in the supplied details is the Rokinon’s known weight versus the Samyang’s AE chip. Against the lighter Canon RF16, this gives EF users a wider specified view but sacrifices the compactness and autofocus listed for Canon’s RF option. It makes most sense when the wide 14mm framing is the priority and carrying weight is manageable.
Pros:- 115.7-degree angle of view fits extensive sky and landscape into a frame.
- The f/2.8 maximum aperture supports night-sky photography.
- Aspherical elements are included in the optical construction.
- Built-in petal-type hood is included.
Cons:- Listed weight of 900g is the heaviest stated figure in this group.
- Manual focus only.
- No image stabilization or weather resistance is specified.
Best for: Canon EF photographers seeking a manual-focus 14mm f/2.8 lens and prioritizing broad framing over low carry weight.
Not ideal for: Travelers trying to minimize kit weight, buyers who need autofocus, or photographers seeking the brightest aperture listed here.
- Focal length:14mm
- Maximum aperture:f/2.8
- Angle of view:115.7 degrees
- Mount:Canon EF
- Focus:Manual
- Weight:31.7 oz (900g)
- Dimensions:6.0 x 3.5 x 3.7 inches
- Optical construction:14 elements in 10 groups
Our verdict“I see the Rokinon as a wide EF-mount alternative to the Samyang, with its listed weight the main reason to rank it lower.”
How We Picked
I ranked these lenses for a defined job: photographing the Milky Way with a wide field of view, where a bright maximum aperture and practical framing matter more than general-purpose versatility. I gave the Nikon the lead because its f/1.8 maximum aperture is the fastest listed here, a meaningful advantage when the camera is mounted on a tripod and the goal is to gather more light without relying only on higher ISO. The 20mm perspective is still broad, though less expansive than the 14mm lenses or the APS-C 10mm.
Next, I weighed each lens against its intended camera system. The TTArtisan 10mm f/2 is a compelling Sony APS-C option, but its format restriction matters as much as its wide view. Canon EF owners can choose between two manual-focus 14mm f/2.8 lenses; I rank the Samyang ahead because its supplied details include a Canon DSLR metering chip and its listed weight is unspecified, while the Rokinon’s listed 900g weight makes it the clearest carrying compromise. That does not prove one lens has better optics than the other.
I also accounted for the Canon RF16’s compact design and autofocus, while keeping its ranking grounded in the limited supplied night-sky information. It is a system-specific, easy-to-carry option, but the fixed 16mm focal length and lack of listed field-of-view or star-corner details make direct optical comparisons harder. Across the lineup, I did not treat autofocus or stabilization as automatic advantages for tripod-based star work: manual focus is common for astrophotography, and none of these listings provides image stabilization. Mount and sensor-format fit come before any ranking.

Factors to Consider When Choosing Wide Field Lenses For Milky Way Photography
I would narrow the choice in this order: confirm the mount and sensor format, decide how much sky you want in the frame, then compare maximum aperture and handling. A lens that does not fit the camera is out of the running, and the widest lens is not automatically the best composition choice for every landscape.
Start with mount and sensor format
Match the lens to the camera system before weighing its other features. The TTArtisan 10mm is for Sony E-mount APS-C; the Samyang and Rokinon are Canon EF options; the RF16 is for Canon RF; and the Nikon is for Nikon F bodies, with FX and DX format compatibility listed. Mount adapters may exist for some systems, but I would not assume autofocus or electronic functions will carry over without checking the camera and adapter details. Sensor format also affects the recorded field of view, so a 10mm APS-C lens is not a direct framing equivalent to a 10mm full-frame lens.
Balance aperture against focal length
A larger maximum aperture lets more light reach the sensor, which can help capture faint stars with a shorter exposure or a lower ISO than a slower lens would require. Here, the Nikon f/1.8 leads on aperture, followed by the TTArtisan f/2; the three f/2.8 choices give up some light-gathering ability. Aperture is only one part of the result: framing, focus accuracy, exposure settings, sky brightness, and the camera sensor all matter. I would not choose a lens from its aperture figure alone.
Choose your field of view for the scene
The two 14mm Canon EF lenses list a 115.7-degree view, while the Sony APS-C TTArtisan lists 105 degrees. The Nikon’s stated angle is 94 degrees, and the RF16 listing does not provide an angle. Wider framing captures more sky, but it can also make foreground subjects appear smaller and require closer attention to where the horizon and landscape sit. A moderately wide view such as the Nikon’s 20mm can give a foreground feature greater visual weight; the 14mm lenses are better suited to expansive scenes.
Plan for manual focus at night
Three lenses here are explicitly manual focus, and even with autofocus models, many astrophotographers prefer to focus carefully on a bright star using magnified live view. At night, a small focus error can soften stars across the frame. I would practice the process before a dark-sky trip, check focus after moving the camera, and avoid assuming a focus ring’s infinity mark will be exact. Autofocus is not the deciding feature for the Milky Way, though it adds convenience for daytime photography and video.
Weigh the kit you will carry
Remote night locations may involve a walk, so size and weight affect how enjoyable a lens is to bring. Canon describes the RF16 as especially compact and lightweight, while the Rokinon lists a weight of 900g. The Samyang’s weight is not specified here, so I would not infer that it is lighter. Tripod use reduces the need for stabilization in a typical Milky Way setup, but neither an unstabilized lens nor a tripod removes the need to manage exposure time and camera movement.
Check the details that are not supplied
These product details do not provide a consistent set of corner-sharpness results, coma measurements, or distortion measurements. Those traits can matter for star points near the edge of a wide frame, so I would seek sample images from the exact camera and lens combination before making a final choice. I would also verify whether a filter can be fitted as intended; the TTArtisan listing gives a 72mm filter holder, while the Samyang and Rokinon have built-in petal hoods. Avoid assuming a standard screw-on filter will fit a lens without checking its front design.
Frequently Asked Questions
Which lens in this group has the brightest maximum aperture?
The Nikon AF-S 20mm has the brightest listed maximum aperture at f/1.8. The TTArtisan follows at f/2, while the Samyang, Rokinon, and Canon RF16 are f/2.8. A faster aperture can help gather more light, but camera format, focus, framing, and exposure choices still shape the finished Milky Way image.
Which lens gives the widest stated view?
The Samyang and Rokinon 14mm lenses both list a 115.7-degree angle of view. The TTArtisan states 105 degrees for its APS-C design. Since those lenses are intended for different camera formats and mounts, the angle-of-view figures and system fit matter alongside focal length when comparing the framing you will get on your body.
Is manual focus a problem for Milky Way photography?
Manual focus is not automatically a drawback for photographing stars. Many photographers use magnified live view to focus on a bright star, then leave focus fixed while composing and shooting. The Samyang, Rokinon, and TTArtisan require manual focus, so they suit buyers willing to set focus deliberately; the Nikon and Canon RF16 add autofocus for other subjects, but autofocus is not a substitute for checking star focus.
Can I use the TTArtisan 10mm on a full-frame Sony camera?
The TTArtisan is specified for Sony E-mount APS-C cameras, not full-frame use. A shared mount name does not change the lens’s stated image format or guarantee the desired coverage on a full-frame body. Check the exact camera and lens compatibility before buying if your kit includes more than one sensor format.
Should I choose 14mm or 20mm for the Milky Way?
I would choose 14mm when I want more sky and landscape in one composition, and 20mm when I want a less extreme wide view with a foreground subject that holds more visual weight. The 14mm choices here are Canon EF f/2.8 lenses, while the Nikon 20mm is an f/1.8 Nikon F lens, so the decision also depends on camera mount and aperture, not just framing.
Conclusion
My recommendation depends on the camera and the kind of frame you want. For Nikon F-mount low-light shooting, I would choose the 20mm f/1.8G for its fastest aperture and balanced wide view. Sony APS-C photographers who want maximum sky coverage should look at the TTArtisan 10mm f/2, provided manual focus and crop-format use fit their plans. For Canon EF users seeking 14mm framing, the Samyang has the clearest practical edge in the supplied details because its listing includes the AE chip; the Rokinon is a comparable manual alternative if its 900g weight is acceptable. Canon RF owners who put portability first have the compact RF16mm, though it is not the aperture leader. I would make mount fit the first filter, then choose between broader coverage, brighter aperture, and easier carrying.
