The M-series has long been favored by photojournalists and has been used to capture iconic imagery across the decades. Continuing the tradition of the series is the Leica M11-P. This model takes the contemporary tech and classic design first seen in the M11 and makes some key improvements. Leica has consistently developed "P" models of their cameras with tweaks that make them better suited to professionals and photojournalists. The M11-P is the world's first camera to feature Content Authenticity Initiative (CAI) technology. In the M11-P, this technology shows up as Leica Content Credentials. By using a secure processing chip, the camera will encrypt image metadata at the point of capture. This information can then be independently verified and even appended when using compatible applications, such as Adobe Photoshop.  The higher resolution suits more detail-oriented applications, like landscape and architectural subjects, and the noise-reduction benefits of the BSI design improve clarity and color accuracy when working in low-light conditions with higher ISOs.This unique pixel binning process allows photographers to select 60MP, 36MP, or 18MP output, with each resolution making use of the full sensor area and providing rich 14-bit color.

The Maestro III processor contributes to the faster processing and Triple Resolution Technology of the M11-P, as well as helps achieve a wider sensitivity range than in past M cameras. An ISO 64-50000 range is now available for greater detail, quality, and natural color rendering at lower ISO settings. An electronic shutter function now permits shooting at shutter speeds up to 1/16,000 sec, which is perfect for working with faster f/0.95 lenses without the need for ND filters. A mechanical shutter still offers shutter speed support up to 1/4000 sec and flash sync at 1/180 sec. Multi-field exposure metering is available in addition to spot and center-weighted average, which helps reduce the need to meter and then re-compose before shooting. The optical viewfinder is a large and bright 0.73x-magnification rangefinder with automatic parallax compensation and bright-line frame lines, which are set to match the image sensor size at a focusing distance of 6.6'.The rear 2.95" 2.3m-dot touchscreen LCD features an updated design that is brighter for improved visibility in sunny conditions.

The M11-P enhances the screen with sapphire cover glass that offers increased scratch resistance. Live view stabilization helps reduce the appearance of camera shake on the rear LCD or optional Visoflex 2; this electronic stabilization makes it easier to manually focus longer focal length lenses with greater accuracy. This silver-chrome finish version of the M11 features a traditional brass top plate. This design weighs about 20% more than the black version, which features an aluminum top plate, and weighs 1.4 lb with the battery installed.BP-SCL7 lithium-ion battery has 64% more capacity than the previous generation's battery and is CIPA-rated for 700 shots per charge. However, if working with the optical viewfinder only, approximately 1700 shots per charge are possible. The USB type-C port can be used in conjunction with the included FOTOS Cable, which allows direct attachment to an Apple iPhone via the Leica FOTOS app for easy file management and sharing.
