Leica SL3 Introduced with 60MP BSI Sensor, Tilting Screen, Hybrid AF, New UI

Today, Leica has announced its highly anticipated third-generation Leica SL professional mirrorless digital camera. The new Leica SL3 stays true to the SL concept, while adding some welcome and innovative updates, both in terms of design and technology.

When the original SL launched in 2015, the camera was already an extremely capable performer, with a robust weather-sealed all-metal body, excellent full frame sensor, responsive touchscreen, class-leading 4.4 megapixel EVF and the first of its stunning L mount full frame optics. Even today, almost a decade later, the SL601 is still a very modern-feeling camera, truly a testament to Leica's forward-looking design and engineering.

The SL2 followed this up in 2019 with a massive resolution jump to 47 megapixels, In-Body Image Stabilization, an even higher quality 5.7 megepaixel OLED viewfinder, improved processing and numerous design improvements. The SL2 has been my main workhorse camera since it came out four years ago, surviving through all my outdoor endeavors.

In less than nine years, Leica has rolled out six zooms, ranging from 14 to 400mm, six reference-class APO-Summicron f/2 prime lenses from 21 to 90mm, two lightweight primes and a high-speed 50mm Summilux portrait lens, while also expanding its flexibility through the L-mount alliance with Sigma, Panasonic and others. In total, there are now eighty-four available lenses in L mount from eight different brands. Correspondingly, the number of users of the SL System and for L-mount cameras in general has also grown significantly.

In the early days of digital photography, technology evolved quickly. This meant frequent upgrades were necessary to fix shortcomings and gain much-needed image quality and usability improvements. As photographers, this meant we were ever hungry for the next generation. But I really never felt this with the SL2. Certainly not initially and not even recently. I just returned from a landscape workshop in Norway and from Japan before that. The SL2 performed just as it always has on my many outings over the years – exceptionally. The camera is an absolute workhorse and delivers image quality that I could have only dreamed of back in my film days. Which led me to wonder, what could Leica really improve upon with its next generation SL3.

Well, the wait is over, and Leica has done what they do best. With the SL3, they have managed to produce a camera that embodies the core design and qualities of the SL System while pushing the technology envelope to deliver photographers’ most frequent requests. Let's dive into some of the biggest upgrades.

60 Megapixel BSI CMOS Sensor

Headlining the changes, the Leica SL3 is now packing the same cutting-edge 60 megapixel BSI CMOS sensor we've seen on the M11 and Q3. With an ISO range of 50-100,000 and an amazing 15-stops of dynamic range, this chip delivers next-level image quality. Just like on the M11, expect a bump in low light performance along with the increased resolution. This is made possible by utilizing BSI technology.

Back Side Illuminated sensors move the supporting electronics to the rear of the chip, allowing for significantly more photosensitive surface area and shallower pixel wells, resulting in no sacrifice versus a lower-resolution traditional design sensor with electronics in the top or middle substrate layers.

The increase in resolution also gives a nice bump to the APS-C crop mode when using TL lenses. Mounting one of the super-compact TL lenses will now offer 26 megapixel files, great for when you want to travel light and don't need massive files.

Triple Resolution

Also borrowed from its M11 and Q3 counterparts, the SL3 now offers triple resolution technology. Select L-DNG for full 60MP images, M-DNG for 36MP and S-DNG for 18MP files. While dropping the resolution of the sensor won't results in any improvement to low light ability, it will reduce file size and increase burst depth. Just as in those cameras, we generally recommend sticking with full-res L-DNG for highest image quality.

Maestro IV Processor + 8GB Buffer

The next-generation custom Maestro IV processor inside the SL3 boasts some serious horsepower. The SL3 boasts a maximum burst rate of 15 fps, despite the resolution increase. And with a generous 8GB of buffer memory, expect burst depths between 70 and 164 shots when shooting at a more modest 2 fps. Regardless of how you shoot, you'll never have to wait for the camera to keep up.

Upgraded video with up to Cine8K

Now possible with the beefy new processor and BSI sensor, the Leica SL3 now offers 8K video. And not just standard 16:9 8K. The SL3 can film in the more cinematic 17:9 Cine8K in 10-bit. For those not up on video standards, this means that the SL3 can record a whopping 35 megapixels at 30 frames per second. If 8K is overkill, the camera supports C4K up to 60fps and FullHD up to 120fps. And while currently limited to FullHD, the SL3 can also record internally to ProRes 422HQ. There's also now a dedicated timecode port on the side of the viewfinder to allow even greater video production flexibility.

New Autofocus with Contrast and Phase Detection

The SL3 features an even more advanced hybrid autofocus system which was debuted on the Q3. Employing traditional contrast detection as well as a phase detect with 315 fields, combined with depth mapping and AI-driven subject recognition, the AF is faster and more accurate than ever. Eye/Face/Body + Animal Detection works remarkably well, and assures sharp focus even for moving subjects.

Smaller and lighter

Looking at the body, you can immediately tell that it’s a little more compact than the SL2. Leica has managed to shrink the dimensions both in length and in height. Standing three millimeters shorter than the SL2 and five point two millimeters narrower from side to side, the camera still exudes the typical tank-like build synonymous with the Leica SL.

Along with the reduction in size, Leica has swapped out a full magnesium build for the previous aluminum construction. Along with a lighter-weight shutter mechanism, the SL3 clocks in a 70 grams lighter than its predecessor. Make no mistake though. The camera is still rock solid and feels incredible in the hand. The chunky grip and diamond textured cladding offer a confident hold. And the camera is still IP54 weather sealed and rated for extreme temperatures. While Leica guarantees functionality from -10 to +40 Celsius, they test internally from -40 to +70 C, with a camera even surviving at a bone chilling -50 C during testing on an Antarctic expedition.

New tiltable rear LCD screen

In a major departure for Leica, the SL3 follows the Q3 sporting an articulating rear LCD. Titling upwards and downwards, the screen offers additional flexibility for off-angle shooting. Whether holding overhead or close to the ground, the screen proves to be a useful addition. The 3.2-inch LCD touch panel itself gets upgraded as well, now clocking in at 2.3 million dots.

Revised control layout

In order to accommodate the new titling screen mechanism, the left-side buttons have been moved to the right of the screen. On the top shoulder of the camera, Leica has added an additional control wheel. Assignable like the one located next to the shutter release, this one defaults to ISO control, mirroring the ISO wheel on the top of the M11. Now, with two top dials and a rear thumb dial, all elements of exposure – ISO, aperture and shutter speed – can all be controlled intuitively with physical dials. As someone who often finds themselves in cold climates, having glove-friendly controls is a huge plus.

New power button

The power switch is now a power button, with an illuminated, multicolored LED ring surrounding it. Leica is clearly highlighting this as a major design shift for the SL3, with it featuring prominently in the initial startup animation. The possibilities of this LED look promising, but the underlying reason was one of functionality. As the SL3 and FOTOS app work much more closely and quicker together, the camera needs to be able to wake from sleep via the app.

New User Interface (UI)

One of the biggest changes though isn’t readily visible from the photos of the camera you might have seen. The new user interface has been completely redesigned and looks amazing. Clean, intuitive, responsive. Leica design at its best. The SL2 UI is already one of the easiest to use on the market, but the menu system in the SL3 is next level. Leica started with their fonts and status icons, increasing their size by a small but impactful ten percent. Line weights were harmonized, and icons were re-imagined to be as clear as possible. The design team coined the term ‘Leicons' to describe these and have over one hundred and fifty of them for the interface of the SL3.

Along with the cleanup, the main control center screen buttons are touch assignable with long presses, a new toggle-style indicator for menu items is super clear, everything is touch friendly and the live view interface now rotates.

Users can control the overlay style of the icons in live view, with the addition of a customizable side bar. And the status overlay icons are clickable, to allow one touch quick changes while shooting. User profiles have been expanded, with six each for photo and video modes, and an entirely new video profile screen offers an easy way to change groups of video settings at once. The new UI is really one of the highlights of this camera.

USB-C and HDMI Ports

The full-sized HDMI port gets a spec bump to HDMI 2.1 to support greater resolution and frame rate options when sending to an external recorder or capture card, and the USB-C port now features transfer speeds up to 100MB/s, resulting in file transfers of less than one second per DNG file. Tethered shooting to Capture One and Lightroom is fully supported. The USB-C port also accepts greater power input, up to 27W, providing quick in-camera battery charging.

Upgraded Wi-Fi Speed

But you don't need a cable to enjoy rapid transfers to your mobile device. By incorporating MIMO 2×2 multichannel beam forming technology, the SL3 boasts 10x faster wireless speeds than the first generation SL. Where DNG files could take 10 seconds or more to transfer from the SL2, the SL33's even larger images take a mere two seconds. Even browsing all of your pictures on the card from FOTOS feels snappy and responsive.

Upgraded Storage

Still offering a tried-and-true SDXC UHS-II slot for backup, the camera’s primary storage gets an upgrade to CompactFlash Express Type B. This means capacities greater than a terabyte and speeds in excess of 2,000 MB/s. The cards are blazingly fast and when paired with a USB 3.2 Gen 2 reader, offer the fastest workflow available.

New Battery

Physically the same dimensions as the BP-DC4 used in the Q2 and SL2, the newly introduced BP-DC6 has 2200mAh on tap for the increased performance of the SL3. The camera is still backwards compatible with the previous 1860mAh battery, but will have reduced battery life and will limit video functions to 4K along with a lower continuous shooting rate. We'd recommend upgrading to the new battery. And yes, the higher capacity BP-DC6 is fully backwards compatible and will work with the SL2, SL2-S and SL601.

New Charger and Power Accessories

The camera supports quick charging in body via USB-C power delivery. Leica recommends using at least a twenty-seven-watt USB-C wall adapter to get the fastest charging available. And don’t worry if all you have is a one hundred forty-watt adapter for you Macbook pro. The camera has intelligent charge circuitry that prevents overdrawing power.

Of course, there is an available BC-SCL6 battery charger for those that want it. And thankfully, it’s a high-speed dual charger with convenient status LED lights for each battery. You can still use the legacy BP-SCL4 single charger from the SL2 and Q2 but charging will be a bit slower. Most SL3 owners will want to go for the Power Set, which includes the dual charger, an extra battery, AC adapter and extra charging cable. Leica is offering the set at a small discount over purchasing these pieces a la carte.

There is also a dummy battery, which Leica is calling a DC coupler. Both the new dual charger and the dummy battery come with USB-C inputs, allowing you to use a wide range of battery packs, wall adapters and longer charging cables. While the lack of an included charger seems like an oversight here, the enhanced USB-C charging ecosystem is a big win.

Rounding out the accessories is a new multifunction handgrip, the HG-SCL7. With a second shutter release button, joystick, thumb wheel and front dial, the handgrip offers the best vertical shooting experience. It also has space for a second battery, doubling the battery life of the camera. And the battery in the handgrip will charge from the camera’s USB-C port for those looking to use the setup in studio.
