The Leica Q3 43 introduces a new 43mm APO-Summicron f/2 ASPH. lens, offering a more focused perspective for portrait and everyday photography compared to the wider 28mm lens of the original Q3. Despite this lens change, the Q3 43 retains the core performance features of the original Q3, including a 60MP full-frame BSI CMOS sensor, 8K video recording, and a hybrid autofocus system with subject tracking. The sensor provides excellent low-light performance, enhanced color accuracy, and digital zoom capabilities, simulating focal lengths up to 150mm. Triple Resolution Technology allows users to choose between 60MP, 36MP, or 18MP outputs while maintaining full sensor usage. The camera's updated Maestro IV processor delivers fast performance, enabling high-speed shooting at up to 15 fps and smooth operation across various modes. Designed with versatility in mind, the Q3 43 also supports 8K video, ProRes recording, and improved connectivity options, including Wi-Fi, Bluetooth, and USB-C. Its physical design features a tilting touchscreen, high-resolution OLED EVF, and a robust magnesium alloy body with IP52 weather sealing, making it a compact, portable choice for multimedia creators.
