In this review, we will be comparing the Q3 Monochrom and the Q3 43, two Large Sensor Compact cameras by Leica. Leica Q3 Monochrom was introduced to the market in November 2025 and Leica Q3 43 was launched in September 2024. There is 14 months difference between Q3 Monochrom and Q3 43 so we don't expect to see a huge technology difference between these two cameras but it would still give an advantage to younger Q3 Monochrom, especially in sensor tech.
We can expect this to be a close match up because both models are ranked amongst the best in Large Sensor Compact cameras. Out of 82 cameras in this class, Leica Q3 Monochrom is ranked
#3 with an overall score of 77 and Leica Q3 43 is ranked
#5 with an overall score of 76.
Q3 Monochrom and Q3 43 are members of Leica's Q series of cameras. Below you can find the latest models from this series.
