LUMIX S1RII 3: AF / STABILIZER

The class-leading autofocus and image stabilization

Phase Hybrid AF with advanced AI technology

High-speed, high-precision AF
The most important aspect of autofocus is its reliability. It's all about how quickly and accurately you can capture and track your subject. The Phase Hybrid AF utilizes 779 focus points to effectively capture dynamically moving subjects. When combined with real-time recognition AF, the LUMIX S1RII delivers exceptional autofocus performance even in challenging conditions, such as backlighting, low-light environments, and with small subjects.
Firmware version 1.2 introduces 10 focus frame colors, enhancing visibility against any subject or background for better usability.*

*Please update the firmware to version 1.2 or later. Download from here.

Improved eye/face accuracy with advanced AI
High-resolution cameras demand extremely precise focusing. The LUMIX S1RII incorporates advanced AI technology for detecting human eyes and faces, resulting in enhanced recognition performance.* This model particularly excels in challenging scenes, such as when the subject's face is tilted or partially obscured, allowing for more accurate focusing on the eyes and face.
With firmware version 1.4, you can switch the AF frame for human eye recognition between the conventional “crosshairs” and the newly added “rectangular” option.

**Please update the firmware to version 1.4. Download from here.

Evolved AF tracking + Real-time recognition
Set Automatic Detection* to ON and position the AF frame at the point where you want to start tracking the subject. AF tracking will automatically start as soon as the subject enters the AF frame, which means you can concentrate on framing and be ready to shoot at the right moment.

*You can switch between Human, Animal, Car, Motorcycle/Bike, Train, and Airplane in the Type of Subject menu under Automatic Detection.

Evolved AF tracking + Human recognition with advanced AI
The performance of the Tracking AF mode has dramatically improved.* The advanced AI instantly analyzes the characteristics of individuals and identifies each subject. Even in scenes where multiple people intersect, such as in sports, it consistently tracks the desired person with precision. **
In addition to automatically detecting up to 15 people, firmware version 1.4 adds a setting to display the recognition frame only for the primary subject.***

*When AF mode is set to Tracking and the Type of Subject under Automatic Detection is set to Human, and Eye/Face/Body is selected from Target Parts.
**It may select another subject if the subjects have similar clothes, colors, or posture, or if the subject you want to shoot is hidden for a prolonged period of time.
**Please update the firmware to version 1.4. Download from here.

Now featuring Urban Sports*

Evolved real-time recognition AF
LUMIX's subject recognition technology continues to evolve, supporting diverse shooting scenarios. The LUMIX S1RII enhances human recognition by adding Urban Sports* to existing detection capabilities for eyes, faces, and bodies, accurately capturing dynamic movements like breakdancing, skateboarding, and parkour.
This model also recognizes bicycles, alongside humans, animals, cars, motorcycles, trains and airplanes, offering detailed targeting options such as human and animal eyes, vehicle windshields, the helmets of drivers and motorcyclists, or the nose of an airplane. Animal eyes, just like human eyes, can be easily switched left or right using the joystick.

*Please update the firmware to version 1.2 or later. Download from here.
･It may not be able to recognize all subjects as per the settings.
･The camera may sometimes recognize non-animal subjects as animals.

Powerful support for hand-held shooting and video shooting on the move

8.0-stop (center) / 7.0-stop (periphery) 5-axis B.I.S.*
7.0-stop (center) / 7.0-stop (periphery) 5-axis Dual I.S. 2**
The LUMIX S1RII features a 5-axis B.I.S. (Body Image Stabilizer) that effectively compensates for handshake, even with lenses that do not have O.I.S. (Optical Image Stabilizer), allowing for slower shutter speeds of up to 8.0-stops (center) / 7.0-stops (periphery).*
In the telephoto range, where the compensation effect of the B.I.S. alone is reduced, the 5-axis Dual I.S. 2 works in conjunction with the 2-axis O.I.S. to achieve a compensation effect of 7.0-stops (center) / 7.0-stops (periphery).** This enables you to express your creativity without worrying about handshake in various situations, including low-light environments and at telephoto distances.

*Center: 8.0-stop; Periphery: 7.0-stop. Based on the CIPA 2024 standard [Yaw/Pitch/Roll direction: focusing distance f = 60mm when S-R2060 is used. 5-axis.]
**Center: 7.0-stop; Periphery: 7.0-stop. Based on the CIPA 2024 standard [Yaw/Pitch/Roll direction: focusing distance f=105mm when S-R24105 is used. 5-axis.]

Compensate for perspective distortion with cropless mode
Advanced E.I.S. + Active I.S.
The LUMIX S1RII provides powerful support for the hand-held video shooting while moving. Active I.S. recognizes camera hand-shake and optimizes the compensation ratio in the pitch, yaw, and roll directions to compensate for significant hand-shake. E.I.S. reduces perspective distortion that occurs during video shooting. The combination of these two functions allows you to record smooth videos even when shooting on the move.
Furthermore, the LUMIX S1RII is equipped with cropless mode,* which compensates perspective distortion during video recording without changing the angle of view, such as when using a wide-angle lens. Improvements have also been made to the compensation performance when using an anamorphic lens.

*This feature can be set using a LUMIX S Series lens. There may be a reduction in the peripheral luminosity when Cropless is set depending on recording conditions such as the lens used, focal length, etc.
**There will be variations in the correction effect depending on recording conditions such as the lens used, the focal length, the video mode used for recording, etc.
