Leica SL Typ 601 is equipped with Maestro II processor and can take pictures up to 6000 x 4000 resolution. Olympus OM-D E-M1 is equipped with TruePIC VII processor and can take pictures up to 4608 x 3456 resolution.

Lens Mount

Leica SL Typ 601 has Leica L lens mount and Olympus OM-D E-M1 has Micro Four Thirds lens mount. Due to Full Frame sensor in Leica SL Typ 601 its crop factor is equal to 1x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length. Due to Micro Four Thirds sensor in Olympus OM-D E-M1 its crop factor is equal to 2x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 2.

No Low-Pass Filter on Leica SL Typ 601

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Leica SL Typ 601. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.

In-Body Image Stabilization on Olympus OM-D E-M1

Olympus OM-D E-M1 has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS). This means that you are still getting vibration reduction when camera is paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.

Built-in GPS on Leica SL Typ 601

Leica SL Typ 601 has a built-in GPS (Global Positioning System) technology which allows you to automatically tag the location where you took your photos. You can later categorize, organize, and search for photos based on location. This is very useful for travel and outdoor photographers for documenting the locations where images were captured.
