Leica Q3 43 – New Q3 with 43mm f/2 APO-Summicron ASPH lens

Today, Leica has announced a new variation of its popular third-generation Leica Q all-in-one full-frame digital camera. The new Leica Q3 43 takes the same technical prowess and design of the standard Q3, but swaps out the familiar 28mm f/1.7 Summilux ASPH lens for a longer 43mm f/2 APO-Summicron ASPH. The Q3 43 marks the first time that a Q camera is available with a lens other than 28mm since the system's initial introduction in 2015.

Inside, the exceptional 60-megapixel BSI CMOS sensor paired with a Maestro IV processor turns out images with 14-stops of dynamic range, with the option of variable resolution DNG files along with expanded digital zoom options up to 150mm equivalent. Equipped with a massive 8GB of buffer memory, the Q3 43 can crank out up to 15 fps bursts. The Live View experience is top notch, with a stunning 5.76 million dot OLED EVF and tiltable 1.84 million dot rear LCD touchscreen.

The autofocus system features a hybrid approach using both contrast and phase detection, meaning quicker and more precise focus. For video users, the Q3 43 offers up to Cine8K recording and ProRes support. The built-in USB-C port allows for in-camera charging, data transfer and support for an external microphone (coming in future firmware), while the HDMI connector enables the use of external video recorders and monitors.

APO-Summicron 43mm f/2 ASPH

Of course, the headlining feature of the Q3 43 is the new 43mm f/2 APO-Summicron lens. Featuring an Apochromatic, or APO, lens design, color aberrations are minimized for even sharper, higher contrast and accurate color reproduction from edge to edge. This designation is reserved for Leica's top tier optics, like the APO-Summicron-M 35mm f/2 and the entire range of APO-Summicron-SL lenses, all best in class.

As to the decision to go with a previously unused focal length of 43mm instead of a more standard 35mm or 50mm, Leica has stated that 43mm is the exact diagonal across 24x36mm full frame. This means that 43mm is the most neutral focal length, providing a natural representation of the human eye. For more practical reasons, Leica probably also realized that 35mm would be a little too close to the existing 28mm in the standard Q3 and 50mm slightly long. In the end, 43mm was the happy medium. And given the outstanding performance and general flexibility, this seems like a good decision by Leica's Q-System and optical design teams.

Lens Design

The complex optical design features 11 elements in 8 groups with 7 aspherical surfaces, employing low dispersion and specialized glass types, ensuring incredible sharp images with the highest color accuracy, and producing stunning image quality at all settings. While not quite as speedy as its f/1.7 Summilux sibling, the f/2 maximum aperture in the 43mm delivers outstanding three-dimensionality with pleasing bokeh and solid low light performance. With a 0.6m minimum focus in standard mode and just 0.26m in macro mode, the 43mm APO-Summicron allows the Q3 43 to get up close and capture even the most minute details, while further improving subject/background separation.

MTF Chart

As you can see from the MTF chart, the lens is a thoroughbred. Almost no aberrations and even perforance acrross the frame with only minor falloff into the corners. Sharpness is consistent at every aperture from wide-open on, only very slightly improving corners two stops down. At f/2, the lens is already resolving almost 90% contrast at 40 lp/mm for crisp fine details. For larger structures, we can see that at 5, 10, and 20 lp/mm, contrast is above 90% from center to edge.

Same Features as Q3

Apart from the ever-so-slightly longer dimensions and a few grams more weight due to the longer coal length lens, the Q3 43 echos the design of the standard Q3 and carries forward all the incredible tech already present in its sister model. But to visually differentiate the camera, Leica has made subtle change, swapping out the standard diamond pattern black leatherette with a nice grey tone. In case you needed a refresher, here's a brief overview of what's under that classy exterior.

60 Megapixel BSI CMOS Sensor

Like the standard version, the Leica Q3 43 is packing a cutting-edge 60 megapixel BSI CMOS sensor. With an ISO range of 50-100,000 and 14-stops of dynamic range, this chip delivers next-level image quality. And despite the massive resolution, the sensor still produces incredible high ISO results in low like 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.

With the high pixel count and longer lens, Leica has expanded the digital crop modes from 60mm up to a 150mm equivalent. While the resulting 5MP images at 150mm might be a bit light on pixels, the 31MP for the 60mm is not. Even 20MP at 75mm equivalent is quite usable. If you do use the crop modes, the on-screen review will show the cropped images, but rest assured that the DNG recorded to the SD card still contains the uncropped, full image off the sensor so you can tweak later.

Triple Resolution

Now introduced across the range of M, SL and Q, triple resolution technology lets you size down your raw images for cases when you don't need full resolution. 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 the M11 and SL3, we generally recommend sticking with full-res L-DNG for highest image quality.

Maestro IV Processor + 8GB Buffer

Making its debut on the original Q3, the next-generation custom Maestro IV processor boasts some serious horsepower. The Q3 upped the already-decent 10 fps maximum burst rate of the Q2 to a blazing 15 fps, despite the resolution increase. And with a generous 8GB of buffer memory, expect burst depths between 63 images at full bore up to 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 Q3 43 shoots shoot 8K video. And not just standard 16:9 8K. The Q3 43 can film in the more cinematic 17:9 Cine8K in 10-bit. For those not up on video standards, this means that the diminutive Q3 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 Q3 was also the first Leica to record internally to ProRes 422HQ.

New Autofocus with Contrast and Phase Detection

Debuting on the Q3 was an all-new hybrid autofocus system, now also on the top-of-the-line SL3. Employing both traditional contrast detection as well as a phase detect with 315 fields, 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.

New EVF

With a 56% increase in resolution over the Q2, the built-in 5.76 million dot OLED EVF is simply stunning. Crisp, clear and smooth, the viewfinder manages to provide an SL3-level experience in a significantly smaller package. And with a 120fps refresh rate, generous eye relief, and easy-to-set diopter the EVF is one of the most notable upgrades.

New tiltable rear LCD screen

In a major departure for Leica, the Q3 and SL3 now sport articulating rear LCD screens. 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 LCD touch panel itself gets upgraded as well, now clocking in at 1.84 million dots, a 76% bump from the Q2.

Revised control layout

In order to accommodate the new titling screen mechanism, the left-side buttons have been eliminated and moved to the right of the screen. Now just a PLAY button and MENU button flank the top and bottom of a four-way direction pad with central FN button.

But even though it appears there is less tactile elements, Leica has expanded the number of custom function buttons to four. In addition to the central one in the D-Pad, there are two at the top rear and one in the middle of the top thumb dial. As with all other Leica models, a long press on any of these buttons lets you set the function, with a short press to activate. While the change of layout will take some getting used to, the Q3 truly offers single-handed use with all buttons falling under your right thumb. Also noteworthy is the inclusion of a threaded shutter release, which means you can customize your Q3 with a wide variety of soft releases – just like an M.

USB-C and HDMI Ports

The Q3 brings back physical connections to the Q System. An HDMI (Type-D) port gives options for recording video to an external recorder or capture device, like using the Q3 as a B/C cam in studio, as a lightweight gimbal-mount camera or maybe just as a really nice webcam for Zoom calls.

And just as with the M11, the USB-C port allows for charging on the go with a portable powerbank, using the camera as a second charger while traveling or for transferring photos to a computer or Apple mobile device. Supplied with a certified MFi USB-C to Lightning cable, transferring photos to an iPhone or iPad with the Leica FOTOS app is quick and easy. Or use a standard USB 3.1 Gen 2 cable to connect to a computer, either in PTP mode for tethered shooting or in Mass Storage to copy files directly to Windows or Mac.

And coming soon via a future firmware update, the USB-C port will also be used to capture audio from external Røde microphones. This will be a major win for video shooters looking for a compact run-and-gun package.

Upgraded Wi-Fi Speed

You don't need a cable to enjoy rapid transfers to your mobile device. By incorporating MIMO beam forming technology, the Q3 boasts 10x faster wireless speeds. Where DNG files could take 20 seconds or more to transfer from the Q2, the Q3's even larger images take a mere two seconds. Even browsing all of your pictures on the SD card from FOTOS feels snappy and responsive.

New Wireless Charging

Along with charging over USB-C, by using the Q3's optional handgrip accessory, the camera can be charged wirelessly on a Qi inductive charging mat. Designed with convenience in mind, the Q3 can be left on its charging mat so it's always fully charged and ready for action.

New Multifunction Protector with Built-In Grip and Arca-Swiss Baseplate

Coinciding with the launch of the Q3 43, Leica is releasing a brand new multifunction protector crafted from elegant black leather. This protector includes an integrated grip, offers direct access to the battery, and can be easilty mounted onto tripods thanks to its built-in Arca-Swiss compatible metal base plate. The protector is priced at $250.

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 Q3. The camera is still backwards compatible with the previous 1860mAh battery, but will have reduced battery life and will limit video functions to 4K. We'd recommend upgrading to the new battery as it becomes available. And yes, the higher capacity BP-DC6 will work with the Q2, SL3, SL2, SL2-S and SL601.
