Updated November 29 2024

Landscape photography is a demanding medium, requiring cameras with high resolution and dynamic range. When considering what cameras should make it on this list, we look at factors like weather-sealing, battery life and operability on a tripod.

We've selected cameras that are most likely to deliver the best possible image quality if you're going to spend hours hiking to the perfect location and waiting for the perfect light. For some picks, we've also considered the best image quality you can get at a certain size and weight of camera body.

Our picks: Best camera for landscapes: Fujifilm GFX 100S II

102MP BSI medium format sensor | In-body image stabilization | 5.76M dot viewfinder

$4999 at Amazon.com$4999 at Adorama$4999 at B&H Photo What we like:
  • Excellent detail capture
  • Very high tonal quality
  • Ready-to-go JPEG or malleable Raws
What we don't:
  • Autofocus not especially fast
  • Video prone to rolling shutter

The GFX 100S II uses the same sensor as the GFX 100 II, but puts it in a body with fewer features – though you do still get essentials like a tilting screen and a stabilized sensor. The result is the only camera with anywhere near this resolution that fits within the price limit of our buying guides, though do keep in mind that you'll also have to budget for medium-format lenses too, which don't come cheap.

While the GFX 100S II has improved autofocus and burst rates compared to its predecessor, its main strength will be landscapes or studio work where it won't have to track dynamic subjects. That makes it slightly less versatile than most of its full-frame competitors, but if you're doing purely landscape photography its image quality will be unparalleled unless you're willing to spend many thousands of dollars more.

Buy at Amazon.comBuy at AdoramaBuy at B&H Photo What we like:
  • Very detailed Raw files with excellent dynamic range
  • Tilt/articulating display suits both photo and video
  • Very reliable autofocus, especially for human subjects
What we don't:
  • Pixel shift high res and focus stacking require desktop s/w
  • Severe rolling shutter for e-shutter and many video modes
The Sony a7R V is the company's fifth-generation high-res full-frame mirrorless camera, built around a stabilized 61MP sensor.

While it's one of the highest-resolution full-frame cameras, the a7R V is quite capable for everyday photography as well, with Sony's excellent autofocus system and 10 fps burst rates. It's not the camera you want if you shoot action or video as often as landscapes, but it can do those things if needed.

The a7R V offers excellent image quality in both JPEG and Raw, giving some of the best results we've seen for its sensor size, though using lossless compressed Raw significantly reduces the burst speed. A multi-shot 240MP high-res mode (combined using desktop s/w) gains a motion-correction function, making it much more usable. The a7R V is an excellent tool for capturing high-resolution images. The body is solidly-built and features a large grip and well-positioned controls, along with a large, high-res viewfinder. A fully-articulating rear touchscreen is mounted on a tilting cradle, adding flexibility. The menus are much improved over older Sony models. The a7R V is an excellent tool for capturing high-resolution images with a mechanical shutter. The impressive autofocus performance means it is suitable for capturing a wide variety of subjects, including sports and wildlife. However, the sensor's slow readout limits its capabilities if your work requires video capture or the use of a silent electronic shutter.

$4299 at Amazon.com$4299 at Adorama$4299 at B&H Photo What we like:
  • Excellent image quality
  • Fast, dependable autofocus
  • Good video support tools
What we don't:
  • Slight reduction in dynamic range in extreme scenarios
  • Tempermental eye control
  • Temperature limits in heaviest video modes
Canon's EOS R5 II is the company's latest high-end, full-frame mirrorless camera, built around a 45MP Stacked CMOS sensor.

If you need a camera that can handle whatever you throw at it, including the occasional landscape photo, the EOS R5 II is the one. Its sensor isn't the highest resolution, but it makes up for it with speed, letting you shoot up to 30fps. It also has the most capable autofocus system on this list, with its dedicated 'Action Priority' modes made specifically for shooting high-speed sports.

The 45MP Raws are highly detailed, and the JPEG sharpening and noise reduction are sensible. It can't quite match higher-resolution cameras like the A7R V, but performs well in its own right. The EOS R5 II does a vast range of things, most of them extremely well: it's impressive for action, landscapes, video, you name it. The grip is very well-shaped and proportioned, and the controls are all well-placed and comfortable to use for extended periods. Eye Control for autofocus is excellent when it works, which isn't always The EOS R5 II has excellent tracking and subject-tracking autofocus performance. The subject detection is effective without getting in your way. It can shoot Raws at up to an extremely rapid 30fps. The EOS R5 II excels at almost everything it tries to do, and that's a long list. It's hard to imagine what photo or video need it won't support you in. Sample galleryThis widget is not optimized for RSS feed readers.

The Nikon Z8 is similalry capable to the EOS R5 II, and its 45.7MP sensor is just as able to take beautiful landscapes, while still handling anything else you throw at it. The two cameras are so evenly matched that the best way to choose between them is by comparing which lenses are available for them, figuring out which system has the ones you want at a price you want to pay, then buying the body to match.

  • Sensor offers some of the best image quality in its class
  • Lovely ergonomics
  • 4K/60p (with a minor crop)
What we don't:
  • Autofocus interface a bit clunky
  • EVF not as high-res as competitors
  • Customization a bit limited
Nikon's Z7 II is a 45.7MP full-frame, image-stabilized mirrorless camera that shoots up to 10 fps bursts, 4K/60p video with a small crop, and offers some of the best ergonomics in the business.

The Z7 II is decidedly last-generation at this point, a fact you'll feel most in its autofocus system. It can still produce crisp images, though, and its age is a benefit when it comes to its price: you can routinely find it for around $2,000, a price bracket that generally contains cameras with half the resolution.

The Z7 II's image quality frequently impresses. It'll match its peers in everything except resolution and, in situations where you can use the greater exposure needed for ISO 64, it has an edge in terms of tonal quality. JPEGs are good but we got the best result from the Raw files. To say the Z7 II is a comfortable camera to hold would be an understatement The Z7 II provides plenty of well-placed controls and a large handgrip, despite its relatively compact body. The additional option to add a battery grip with duplicate controls is valuable. We'd like more control over what can be applied to custom buttons and we miss the AF mode control from the front of Nikon's DSLRs, though.

\The Z7 II is a capable camera that can produce superb image quality. Its autofocus performance and interface aren't quite up there with modern mid-to-high-end cameras, but overall it's a good, capable camera. The improvements over the original version help expand the range of circumstances in which it performs well.

Buy now:

$1599 at Amazon.com What we like:
  • Dedicated dial interface shows your settings
  • Detailed 40MP images
  • Photo-centric design and feature set
What we don't:
  • Autofocus prone to false-positives
  • Significant rolling shutter in e-shutter mode
  • Smaller buffer, lower-spec video than X-H2
The Fujifilm X-T5 is a classically-styled, photo-focused 40MP enthusiast mirrorless camera, based around an image-stabilized BSI sensor.

If the landscapes you're hoping to capture are far off the beaten path, the X-T5 may be worth a look. While it's marginally smaller and lighter than its full-frame and medium-format counterparts, the real weight savings will come from the lenses you can equip it with. Fujifilm's lineup of APS-C lenses is unmatched, and can make for a kit light enough that you won't have to reconsider hiking an extra mile or three to get the shot.

The X-T5 produces highly detailed Raw and JPEG files, with the latter benefiting from Fujifilm's array of attractive 'Film Simulation' color modes. A 40MP APS-C sensor means relatively high pixel-level noise but results that are competitive when viewed at a common output size. The X-T5 foregoes some of the X-H2's video features to offer a more photo-centric experience with classic styling The X-T5 features dedicated control dials for ISO, shutter speed and exposure compensation, along with a film-era SLR-style low-profile front grip. Its rear screen tilts up and down but also hinges outward for portrait-orientation shooting. Having the X-H2 and X-H2S available to meet the needs of videographers allows the X-T5 to fulfill photographers' desires for stills-centric handling and features. For photographers who enjoy Fujifilm's traditional dial-based controls, there's no more capable body than the X-T5. Sample galleryThis widget is not optimized for RSS feed readers.

Canon's EOS R7 is a bit heavier than the X-T5, and its APS-C lens selection isn't nearly as robust, but its 32.5MP sensor will be more than capable of capturing detailed landscapes. Its faster burst rates and better autofocus tracking also give the edge over the X-T5 for when you're shooting in the city instead of the wild.

On this day 2003: we reviewed the world's first designed-for-digital SLR

Digital Photography Review news -

The Olympus E-1 was the first DSLR designed solely for digital. The sensor format choice was independent of any film legacy and the lens design was specifically focused on the way digital sensors accept light. Leica's S series of 45x30mm medium format DSLRs is the only comparable system we can recall.

It's 21 years since we reviewed the Olympus E-1, arguably the only successful attempt to develop a digital SLR from first principles, rather than trying to adapt what had come before. As part of our 25th Anniversary celebrations, we look back at the E-1 as one of the most significant cameras of the past 25 years.

In the early days of digital photography the large number of photographers already heavily invested in film lenses put pressure on companies to continue their existing systems, even though 'full-frame' sensors that matched the film format they were designed around were prohibitively expensive for most photographers.

The Four Thirds system was an attempt at a clean slate design, with the intention of developing a new set of lenses designed to suit digital sensors, and built around a sensor chosen because it had a good performance-to-price ratio, not to match the arbitrary dimensions of cinema film stock adapted for photography in the early 1900s. It was a decision that would also allow smaller lenses, particularly at longer focal lengths.

The first open system: the Four Thirds timeline

The Four Thirds initiative was started by Kodak and Olympus, with the two companies settling on a 5MP Type 4/3 (17.3 x 13mm) CCD sensor. This sensor size and the use of the 4:3 aspect ratio common in most early digital sensors give the system its name.

They also announced it would be an open standard, with other companies welcome to join, a decision that prompted Fujifilm to announce its interest, followed by Sanyo, Sigma and Panasonic, some seventeen months later. For a while it looked like a critical mass might coalesce, finally bringing about the long dreamt-of common mount, allowing complete interoperability between multiple brands.

In the meantime, although later than the initially suggested Feb 2002 launch date, Olympus developed the E-1, a high-end magnesium alloy DSLR with a 100% viewfinder and that 5MP Four Thirds CCD at its heart. Announced alongside five lenses in mid 2003, the original press release highlights the 'Supersonic Wave Filter' sensor shake system that shook dust off the sensor as solving "a problem that has long been an Achilles heel of ... digital SLRs."

Unfortunately, in his review, Phil highlighted that the Olympus couldn't offer either the speed or the resolution that were typically expected of a camera with the E-1's stated professional ambitions. This was made more stark by its $2199 original price tag (albeit with a 'street price' well below that), at a time when Canon's 6MP EOS 10D would set you back nearer $1500.

It took the more affordable E-300 model for the Four Thirds to really find its audience. By the time the E-330 arrived, two years later, Kodak was out of the picture.

It took 2004's 8MP E-300, with its much more attainable price point (around $1000 with kit lens) for Four Thirds to really find its audience.

By 2006 Panasonic and Leica were alongside Olympus spearheading the system, with each brand releasing variations of technologies co-developed by the two Japanese companies, including "Live MOS" sensors from Panasonic, rather than Kodak. The Olympus E-330 and Panasonic L-1/Leica Digilux 3 were some of the first DSLRs to offer live view, with the E-330 including a more sophisticated/complex implementation. You don't have to squint very hard to see the beginnings of the first mirrorless camera, which Panasonic would introduce just two years later.

Despite a broadly sound initial concept, one challenge of the use of a smaller-than-film sensor in a DSLR was that the viewfinders were often quite small and dark (because the sensor size defines the size of the camera's mirror, which in turn puts a limit on how large or bright you can make an optical viewfinder).

This was resolved with the move to a mirrorless design and the creation of the Micro Four Thirds system, built around the same Type 4/3 sensor format and a lot of technology developed during the Four Thirds era. Perhaps fittingly, the final Four Thirds camera was a direct continuation of the original E-1 line, with the system being officially discontinued 18 months later.

With this in mind, it might seem odd to call a system with a span of just over seven years between the launch of its first camera and its last a success, but I'd focus more on the groundwork it laid. Twenty-one years after the launch of the E-1, the Four Thirds sensor format is still very much with us, and you can trace a direct line from the first all-digital DSLR project to the mirrorless cameras that dominate the ILC market today, even if both Kodak and Olympus have now exited the photography market.
