Compatibility: Canon EF, Nikon F-mount, Sony E-mount, L-mount
Focal range: 14mm fixed focal length
Aperture range: f/1.4 - f/16
Autofocus: Yes. HLA motor
Thread size: 82mm
Weight: 1.6 lbs (725 grams)

Reasons to buy

+
Well-built, reliable and durable lens
+
A marvel at creating sharp low light images
+
Great autofocus, color rendition and overall image reproduction

Reasons to avoid

-
Heavy and bulky
-
Needs a tripod to maximize its potential
-
Only for those with the budget
Buy it if

✅ You want the best: Optically, we think this might be the best lens for astrophotography out there.

✅ Maximum aperture is a deal-breaker: A maximum of f/1.4 is ideal for astro.

✅ Build quality is important: We feel like this lens is built to last.

Don't buy it if:

❌ You need something lightweight: This lens is quite heavy and best used with a tripod.

❌ Zoom is important: The fixed 14mm focal length can be restrictive for some.

The bottom line

🔎 The Sigma 14mm f/1.4 DG DN Art lens is staggeringly good for astrophotography. Better yet, its speedy autofocusing and ability to declick the aperture ring for video makes it useful for hybrid shooting as well. ★★★★★

Design: The lens is a remarkable achievement in lens design and optical performance. It’s also well designed, sturdy, well constructed and feels ergonomically pleasing to use. If you’re committed to a style of photography that uses a tripod, we wholeheartedly recommend it, but the relatively heavy weight of this lens would lead us to suggest that it’d be worth looking at in person and actually holding one before you decide to purchase.

Performance: The excellent low-light performance and sharp image quality make this lens an absolute joy for astrophotographers. It's versatile enough for various other photography genres, like architecture, portraiture or live events. We even found that the impressive f/1.4 aperture allows handheld shooting in some low-light conditions. Color rendition within the lens is excellent, as is distortion control.

Functionality: When we reviewed the Sigma 14mm f/1.8 DG HSM Art Lens, we were impressed at the wide range of features included on the lens, again making it suitable for a number more types of photographers than you’d first imagine. There is a good approach to aperture control, and there is a manual ring with detents at every third of a stop, or there's an auto mode and even a switch to declick the control for videographers.

Best Sony lens

Best for Sony cameras: The 12-24mm has outstanding optical clarity but a price to match

Focal range: 12mm-24mm
Aperture range: f/2.8 - f/22
Autofocus: Yes. XD (extreme dynamic) Linear Motor AF

-
Eye-wateringly expensive 
Buy it if

✅ You want exceptional image quality: this lens has incredible optical clarity.

✅ You want a large viewing angle: the shortest focal length gives an angle of 122 degrees.

Don't buy it if:

❌ You're on a budget: this lens is one of the most expensive on this list.

❌ You use front filters: they are not supported on this lens due to the domed glass.

The bottom line

🔎 The Sony FE 12-24mm f/2.8 GM is great if you don't want to commit to one photography niche. It is versatile enough to have the option to use the wider 12mm for nighttime shots, while also being able to zoom in for daytime landscapes. ★★★★

Design: The Sony FE 12-24mm f/2.8 GM comes from Sony's elite 'G-Master' line of lenses, making it one of the best-quality lenses in this guide, but also the most expensive. Despite its compact size and lightweight design, this lens delivers exceptional performance with an f/2.8 aperture and an impressively wide field of view, all while weighing only 1.87 lbs.

This lens is a very attractive option for anyone looking for an ultra-wide-angle lens without the added weight, all while preserving excellent build quality. However, due to its large aperture and extremely wide field of view, it's worth noting that the front glass element is quite large and bulbous, which means you can't use traditional lens filters on it.

The glass is shielded by a petal-shaped integrated hood, although using a front filter isn't an option without spending money on an adapted filter system. The good news is that there's a slot on the back of the lens for gel filters. 

Performance: The image quality from this lens is nothing less than spectacular. When we reviewed the Sony FE 12-24 f/2.8 GM lens stars appeared extremely sharp in the center of the image and still very sharp in the corners throughout the full focal length range, even at the widest aperture of f/2.8. Even for wide-angle landscape photography, this lens produced stunning images and we loved shooting with it.

Functionality: The shortest focal length of 12mm gives a whopping viewing angle of 122 degrees — this is perfect for capturing huge portions of the Milky Way and night sky landscape, which can only be achieved by taking panoramas with many other lenses.

If you want top-notch quality in your astrophotography and have the budget for it, this Sony lens is a winner. While the price is undoubtedly high, its versatility makes it a potential all-in-one wide-field astro lens. If your budget is tighter but you still want an ultra-wide-angle lens for astro, the next one on this list might be a better fit for you.

Aperture range: f/2.8 - f/22
Autofocus: Yes
Thread size: 112mm with supplied hood

Buy it if

✅ You want a lightweight lens: at just 1.4 lbs, this is one of the lighter picks on this list.

✅ You use filters a lot: both front and rear filters are supported.

✅ You want to reduce post-processing: this lens creates minimal aberrations.

Don't buy it if:

❌ You're on a budget: this lens is one of the more expensive ones on this list.

❌ You already own filters: this lens requires large 112mm filters.

The bottom line

🔎 The Nikkor Z 14-24mm f/2.8 S combines a lightweight and compact design with exceptional image quality. It creates very few aberrations and has a handy LCD display. ★★★★½

Design: This Nikon zoom lens is fully weather-sealed for protection against the elements and it stands out as the shortest among full-frame f/2.8 ultra-wide-angle zoom lenses available. It's lightweight at 1.7 lbs, compact and maintains a wide aperture with a broad viewing angle at the shorter end of its focal range.

The customizable Lens Function (L-fn) button also allows users to quickly change exposure and adjust settings without having to flick through endless menus, which is useful when you need to act fast to avoid missing a shot.

Compared to similar models from other brands, the front element of this lens is far less bulbous, which allows you the option to attach 112mm filters to the front of the lens using the provided lens hood, further opening this lens up for daytime use as well as astro. It's worth noting that the cost of these filters may be a little out of reach, but having the option to do so is a nice feature.

Performance: The Nikkor Z 14-24mm f/2.8 S provides outstanding image quality, minimal distortion, vignetting and aberrations. The LCD display on the lens barrel is especially helpful for astrophotographers, allowing adjustments in the dark without the need for a headlamp.

✅ You want exceptional image quality: you can't get much better results than with this lens.

✅ You want a large maximum aperture: with a range of f/1.8 - f/16, this lens is hard to beat.

✅ You want a sturdy lens: this high-quality build means this lens will last.

Don't buy it if:

❌ You want a lightweight lens: at 2.58 lbs, this isn't the lightest lens on this list.

❌ You want a versatile focal length: at 14mm fixed, this lens is a bit niche.

You use filters a lot: this lens isn't equipped with a filter thread.

The bottom line

🔎 The Sigma 14mm F1.8 DG HSM ART lens really is a phenomenal lens for night-sky photography. If you’re after a lens that will get you long shutter speeds without a star tracker, with technically excellent results throughout its aperture range, this is a piece of kit that will serve you well. ★★★★★

Design: The weight was one of the very first things we noticed when conducting our Sigma 14mm f/1.8 DG HSM Art review. Coming in at 2.58 lbs, it's definitely on the heavier side for a lens, but with heft in the hand comes heft in terms of optical quality too. 

Not only is this lens exceptionally well-built, but it comes with the added advantage of being weather-sealed. Astrophotographers typically don't shoot in adverse weather conditions at night, but this feature can be handy if you intend to use the lens during daytime outings. When it comes to nighttime shooting, the lens's fixed focal length and exceptionally wide field of view make it perfect for capturing vast landscapes of the night sky.

It's worth mentioning that the lens lacks a filter thread because of its bulbous front element. While it's not a deal-breaker for astrophotography, it's something to consider if you intend to use the lens in the daytime and want to protect the glass better.

Performance: The lens excels in optical performance, providing exceptional quality all-round. Even at its widest f/1.8 aperture, the stars remain sharp and clear. However, closing the aperture slightly can help minimize distortion in the corners of the image frame when you're shooting wide open.

The chromatic aberration (color fringing) is minimal even when shooting at wide apertures and you also won't encounter any significant issue with image distortion — something which certainly cannot be said for all ultra-wide lenses.

As far as ultra-wide lenses go, the Sigma 14mm f/1.8 DG HSM Art is close to unbeatable in terms of its performance and quality.

Don't buy it if:

❌ You want edge-to-edge sharpness: this lens reveals softer edges at f/2.8.

The bottom line

🔎 The Canon RF 15-35mm f/2.8L IS USM is the brand's best ultra-wide zoom lens which makes it a sound investment for photographers. Unfortunately, it’s also quite pricey so it may put off some that are on stricter budgets. ★★★★½

Design: The Canon RF 15-25mm f/2.8 IS USM has a simple and sleek design, with only two buttons on the lens itself to operate the autofocus/manual focus and stabilizer. It's easy to store away in whatever camera bag you use thanks to the fact that it maintains the same shape all the way down the barrel of the lens. 

We were pleased to see there's a large 82mm filter thread in the middle of the front element, making it easy to attach screw-in filters without requiring an adapter. The smooth and quiet operation of the focal length and focus rings is another positive feature, ensuring a hassle-free experience for time-lapses or video recording.

Performance: In our Canon RF 15-25mm f/2.8 IS USM review, we tested the lens out with the Canon EOS R6 camera and were extremely impressed with the results. It had excellent autofocusing speed and produced super-sharp images, with only a tiny bit of sharpness dropoff at the very edge of the image when shooting wide open at f/2.8. 

When we reviewed the photos, we noticed a very slight chromatic aberration around the frame's edge, but only when zoomed in to 400%. While that's not ideal at this price point, especially for astrophotographers shooting wide open, the overall image quality was stunning.

Functionality: This lens features a healthy five stops of image stabilization, which can be increased to eight stops when attached to one of Canon’s RF mount cameras with in-body stabilization. This makes it a great choice for anyone who enjoys handheld shooting. It also has an incredible zoom range of 15-35mm, giving it the versatility to handle wide landscape shots as well as fine up-close detail. We think it's a must-have for any RF-mount Canon users.

The bottom line

🔎 The Sony 14mm f/1.8 G Master is ideal for seasoned astrophotographers or professional street photographers that need a wide field of view combined with sharp optics and a fast f/1.8 maximum aperture. ★★★★½

Design: This bright, ultra-wide 14mm prime lens is Sony’s answer to Sigma's 14mm f/1.8 DG HSM Art lens. Both lenses offer the same fixed focal length and maximum aperture, but there's a substantial difference between the two. 

The Sony FE 14mm F1.8 GM has been designed specifically for its mirrorless system, which means Sony has been able to engineer a much smaller and lighter lens than the Sigma. For comparison, the Sony weighs in at 1.02 lbs and the Sigma tips the scales at a chunky 2.6 lbs. This translates into a much better balance when the native Sony lens is fitted to a Sony camera — not to mention it's much more pleasant to carry around with you on shoots, which we were very grateful for when we reviewed the Sony FE 14mm f/1.8 GM.

Sony's FE 14mm f/1.8 GM stands out as Sony's widest full-frame prime lens, boasting high-resolution quality, weather sealing and smooth focusing common in Sony's G-Master lenses. Additionally, it features a handy aperture control ring for quick manual adjustments to exposure and other settings, which is particularly beneficial in low-light conditions when you can't see some of the buttons.

Performance: This wide-angle lens delivers exceptional image quality from f/1.8 all the way up to f/16. It maintains sharpness, creates lovely bokeh (background blur) and produces captivating sunstars even at f/4. It performs excellently at its widest aperture of f/1.8, with only a minimal amount of vignetting that can easily be corrected during post-processing.

Functionality: The image quality is insanely impressive considering this lens doesn't have image stabilization, even though most full-frame camera bodies do tend to have in-body image stabilization nowadays anyway. Plus, you won't need image stabilization for astrophotography as the camera will be on a tripod.
