Camera Overview — Leica Q3 43

The Leica Q3 43 is a full-frame mirrorless camera built around a fixed APO-Summicron 43mm f/2 lens — an apochromatic design that corrects chromatic aberration optically rather than relying solely on software. The 60.3-megapixel BSI CMOS sensor with a Bayer color filter array delivers substantial resolving power, and Leica's in-camera crop modes extend the camera's effective reach: shooting at 1.4x crop yields a 60mm equivalent at 30.8MP, while a 2.1x crop produces a 90mm equivalent at 13.9MP, all without changing glass. The lens features a leaf shutter capable of up to 1/2000s mechanically and up to 1/16000s electronically, with built-in image stabilization.

For video, the Q3 43 records up to 8K resolution in H.265 at 300Mbps with 10-bit 4:2:0 color, and steps up to DCI 4K or UHD 4K at up to 60p in H.264 at 600Mbps with 10-bit 4:2:2. Apple ProRes 422 HQ is supported up to 1080p at 60p. Log profiles include L-Log and HLG.

The autofocus system is hybrid, combining PDAF and contrast AF with DFD, and includes subject recognition covering Eye, Face, Body, and Animal detection. The OLED EVF resolves 5,760,000 dots at 0.79x magnification, while the 3-inch tilt touchscreen resolves 1,840,000 dots. Continuous shooting reaches up to 15fps in 12-bit AF-S mode or 7fps in 14-bit AF-C mode.

The lens accepts 49mm filters and focuses as close as 0.27m in macro mode.

Key Features — Leica Q3 43

60.3MP Full-Frame BSI CMOS: The full-frame 60.3MP back-illuminated sensor delivers high resolution and a native ISO range of 100–100000 (extendable to ISO 50), giving the camera strong dynamic range and low-light capability in a compact fixed-lens body.

APO-Summicron 43mm f/2 Lens: The apochromatic lens design corrects chromatic aberration optically through 11 elements in 8 groups (including 7 aspherical elements), producing sharp, color-accurate images without relying on software correction.

Six In-Camera Crop Modes: Built-in digital crop modes simulate focal lengths from 43mm at 60.3MP all the way to 150mm at 5MP, effectively giving the camera multi-focal-length versatility without changing glass.

Leaf Shutter with Full Flash Sync: The in-lens leaf shutter syncs with flash across its full mechanical speed range up to 1/2000s, making it highly practical for high-speed flash work in bright conditions — an advantage typically unavailable on focal-plane shutter cameras.

8K Video Recording: The camera records DCI and UHD 8K video in H.265 at 300Mbps with 10-bit 4:2:0 color, and steps up to 10-bit 4:2:2 DCI/UHD 4K at up to 60p in H.264 at 600Mbps for higher-quality color grading.

L-Log and HLG Support: Built-in L-Log and HLG gamma profiles preserve highlight and shadow detail in video, giving videographers greater flexibility in color grading during post-production.

Description — Leica Q3 43

The Leica Q3 43 pairs a 60.3MP full-frame BSI CMOS sensor with a fixed APO-Summicron 43mm f/2 lens built on an apochromatic optical design — 11 elements in 8 groups, with 7 aspherical elements — that corrects chromatic aberration optically. The sensor covers a full 36 x 24mm area and offers a native ISO range of 100 to 100000, with ISO 50 manually selectable as an extended option. Six in-camera crop modes let shooters work at equivalent focal lengths from 43mm at 60.3MP all the way to 150mm at 5MP.

The leaf shutter covers the full mechanical range up to 1/2000s for flash sync, with electronic shutter reaching 1/16000s. Video capabilities span DCI and UHD 8K at up to 300Mbps in H.265 with 10-bit 4:2:0, through to DCI/UHD 4K at 600Mbps in H.264 with 10-bit 4:2:2 at up to 59.94p. The 5,760,000-dot OLED EVF at 0.79x magnification pairs with a 3-inch tilt touchscreen at 1,840,000 dots.

Continuous shooting tops out at 15fps (12-bit AF-S) or 7fps (14-bit AF-C). The camera accepts 49mm filters and focuses down to 0.27m in macro mode.

Frequently Asked Questions — Leica Q3 43

What focal length is the built-in lens and what is its maximum aperture?+
The fixed lens is a 43mm APO-Summicron with a maximum aperture of f/2. It uses an apochromatic optical design to correct chromatic aberration optically and consists of 11 elements in 8 groups, including 7 aspherical elements.
What is the highest video resolution the Q3 43 can record?+
The camera records up to 8K in both DCI and UHD formats using H.265 at 300Mbps with 10-bit 4:2:0 color, at frame rates up to 29.97p. For higher frame rates, DCI 4K and UHD 4K are available at up to 59.94p in H.264 at 600Mbps with 10-bit 4:2:2.
How does the crop mode system work for extending reach?+
The Q3 43 offers six crop modes that digitally zoom into the sensor, producing equivalent focal lengths of 43mm, 60mm, 75mm, 90mm, 120mm, and 150mm at resolutions ranging from 60.3MP down to 5MP respectively. This allows meaningful reach extension while retaining usable resolution at many crop factors.
Does the camera support log video recording?+
Yes, the Q3 43 supports both L-Log and HLG log profiles for video, providing flexibility for color grading in post-production.
What autofocus modes are available?+
The hybrid autofocus system (PDAF + Contrast AF with DFD) supports AF spot, AF field (shiftable and scalable), Multi-field, Large zone, Eye/Face/Body detection, and Eye/Face/Body with Animal detection. Subject recognition is included, though AF point display with subject recognition is not supported.
What are the closest focusing distances for standard and macro shooting?+
In standard mode the minimum focus distance is 0.6m (23.6 inches). In macro mode the camera focuses as close as 0.27m (10.6 inches), with a maximum macro working distance of 0.6m.
