A New Vision For Professional Photography

Leica SL (Typ 601) Mirrorless Digital Camera Best-in-class may be understated describing the Leica SL (Typ 601) Digital Mirrorless Camera, an outstanding full-frame camera that is presenting professional photographers the 'new Leica experience.' This era of Leica is intended to take the top place of modern imaging technology and by the application of a supurb 24MP CMOS sensor combined with Leica's Maestro II processor, it will provide among the finest in image quality with sensitivities ranging from ISO 50 thru 50000. The sensor also renounces the use of a low-pass filter as a way to maximize possible detail, particularly when using one of the many Leica's outstanding lens collections. And, to fashion the camera as a genuine professional's tool, Leica has added internal DCI 4K (4096 x 2160) video capture using 24 frames per second in a Super35 fashion, along with the L-Log gamma for the ultimate dynamic range.

Beginning with still images, the combination sensor and processor provides high-resolution images at a rate as fast as 11 fps. The 2GB internal buffer also delivers bursts of up to 33 DNG files or boundless JPEGs. The AF Contrast system is alleged to be the fastest among full-frame cameras facilitated by 49 fields. This safeguards that photographers will not miss the decisive moment in time.

There is outstanding video, featuring UHD 4K (3840 x 2160) at 25 and 30 fps available as addition to DCI 4K when applying the camera's Super35 function. Alongside this impressive resolution is the capacity to make use of the L-Log gamma, a super flat profile maximizing the dynamic range of the photo and gives editors added information available in post production. Video is easily captured internally using the UHS-II and UHS-I accepted SD card slots at 4:2:0 8-bit sampling rate although it can be output using HDMI with 4:2:2 10-bit sampling.

Also available is Full HD (1920 x 1080) and standard HD (1280 x 720) at up to an impressive 120 fps for slow motion in the camera's full-frame mode. Numerous other video recording features were implemented on the SL (Typ 601) to make high-quality recording easier, this includes focus peaking, exposure simulation, clipping/zebras, grid overlays, aspect ratios, and safe area. Audio is also supported with a built-in stereo microphone and users can add both a 3.5mm headphone jack and 3.5mm microphone input with the optional AA-SCL4 Audio Adapter. Manual and auto audio control is available.

Made in Germany from two blocks of solid aluminum, the SL (Typ 601) fits right in with Leica's other precision made imaging tools. This body is designed for intuitive use, with numerous dials and buttons in addition to the implementation of a rear 2.95" 1.04M-dot rear LED touchscreen for hybrid operation as part of Leica's Professional user interface. The body also offers a spacious 0.66" EyeRes 4.4MP EVF with a fast refresh rate of 60 fps and a magnification of 0.8x for more natural handling and composition.

The weather-resistant body has a variety of other features packed into it with dual SD card slots, one with the UHS-II standard and a backup with the UHS-I standard, as well as a 1.3" top monochrome LCD screen for quickly viewing and changing exposure settings. Along with all of this, the SL (Typ 601) has built-in Wi-Fi connectivity for remote control and image capture using the Leica SL App and a GPS unit for geo-tagging your photographs.
