If you are a professional photographer and looking for the best Mirrorless Camera for your Photography. I suggest you top 5 Mirrorless Camera. They are bellow:

1. Sony A9 Mark II Body (Black)

The Sony Alpha a9 II takes the impressive feature-set of its predecessor and adds enhanced connectivity, a refined body design, and even quicker performance. Additionally, 5-axis SteadyShot INSIDE sensor-shift image stabilization is available, too, which minimizes the appearance of camera shake by up to 5.5 stops. Benefitting the imaging capabilities, the a9 II receives a dramatic update in its physical design, featuring a more ergonomic body shape, refined weather sealing, and improved connectivity. Additionally, Voice Memos enables you to record up to 60-second sound clips with each photo, which can then be automatically converted to text, using the Transfer & Tagging app add-on and then embedded into files’ metadata. The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times along with a wide dynamic range with smooth tonal rendering. Additionally, the use of phase-detection points enables the use of A-mount lenses via the optional LA-EA3 or LA-EA1 lens mount adapters with full continuous AF/AE tracking compatibility. Autofocus can also be used in conjunction with the Focus Magnifier function for critical focus when homing in on minute subject details. The a9 II also features a 3.5mm microphone input jack for compatibility with external microphones. Full-frame 4K recording has also been dramatically improved for improved quality when working at mid to high sensitivities to permit full use of the entire sensor width. The a9 II incorporates an enhanced 5.5-stop effective 5-axis SteadyShot INSIDE image stabilization system, which compensates for five different types of camera shake encountered during handheld shooting of stills and video.
2. Fujifilm GFX 50S Body Black

The FUJIFILM GFX 50S delivers the world’s best image quality. It combines the outstanding resolution of 51.4 megapixels with exceptional tones, advanced color reproduction, and high-performance lenses. This level of image quality is purely motivational. The world around you changes the moment you hold this camera in your hand. Appreciate all that can be achieved with Fujifilm’s new medium format mirrorless camera system, GFX.
3. Leica CL (Black) W/ TL 18mm F2.8

The Leica minimalist yet functional school of thought, the black CL is a compact, sleek mirrorless digital camera offering intuitive control and a versatile range of imaging capabilities. An electronic shutter function permits totally silent operation along with shutter speeds up to 1/25000 sec, and a 49-point contrast-detection autofocus system affords quick and accurate performance. Additionally, built-in Wi-Fi connectivity also enables wireless sharing and remote camera control from a linked mobile device. The built-in electronic viewfinder has a 2.36m-dot resolution and 0.74x magnification for bright, clear eye-level viewing. A manual +/-4m diopter is also available to suit different vision strengths. Top and bottom covers are constructed from milled and anodized aluminum alloy while the front and rear body shells are magnesium alloy for an overall construction that is rigid yet lightweight. Additionally, as with most mirrorless today, the L mount can accept a variety of adapters, such as the M-Adapter L which provides shooters with access to the entire M-mount lens library.
4. Panasonic Lumix DC-S1H Body Black

The Panasonic Lumix DC-S1H is clearly distinguished by its impressive video capabilities but also features notable flexibility to suit multimedia applications along with an especially durable design. Using nearly the full sensor, 3:2-format 6K24p video recording is supported, along with 16:9 5.9K30p and both DCI and UHD 4K60p settings with internal 4:2:2 10-bit sampling. Variable Frame Rate (VFR) recording also permits using slow and quick motion effects and High Frame Rate (HFR) settings allow the use of higher frame rates in conjunction with 10-bit sampling. Additionally, V-Log has been pre-installed, and a Hybrid Log-Gamma is also available for achieving greater detail when recording, and to benefit color grading during post-production. Also benefitting stills, as well as video, is a 225-area Depth from Defocus (DFD) contrast-detection autofocus system that achieves quick and precise focusing and subject tracking. Beyond the imaging attributes, the S1H is also characterized by its body design, which incorporates an impressively high-resolution 5.76m-dot OLED electronic viewfinder along with a 3.2″ 2.33m-dot tilt free-angle touchscreen LCD. The Venus Engine’s processing power also helps to suppress noise levels throughout the sensitivity range, from ISO 100-51200, and yield fast full-resolution continuous shooting speeds up to 9 fps with AF-S or 6 fps with AF-C, for more than 60 consecutive raw files. Full HD and Anamorphic 4K recording settings are also supported at up to 119.88p and 48.00p, respectively. Optimizing your recording for post-production color adjustment, the S1H features a pair of gamma settings suited to capturing a wide dynamic range. An SMPTE-compliant time code can be embedded for easier syncing of footage from multiple cameras. Front and rear tally lamps can be used to visually indicate recording and standby settings for faster visual recognition by subjects and camera operators.
5. Leica M10-P Silver

The silver chrome Leica M10-P is a digital rangefinder camera that blends enhanced still imaging capabilities with an updated, pared-down appearance as well as the quietest shutter of any film or digital M-series camera. Akin to its sibling model, the M10, the M10-P features a slim body profile reminiscent of M film cameras, and the larger 0.73x-magnification optical viewfinder allows for greater composition and focusing accuracy. Also contributing to durability, the top and bottom plates are constructed from brass and the chassis is built from magnesium alloy to realize a robust physical construction for long-lasting use. Additionally, the M10-P also sports an integrated Wi-Fi module for wireless sharing and remote camera control from a linked mobile device. Taking the M10 to more inconspicuous places, the M10-P is a sleek evolution of the pared-down, simple camera system. The image processor also incorporates a 2GB buffer to afford fast continuous shooting at 5 fps for up to 40 consecutive frames in a burst. The effective rangefinder metering basis is 50.6mm (mechanical metering basis 69.31 mm x viewfinder magnification of 0.73x). Built-in Wi-Fi permits sharing imagery directly to a linked smartphone and also enables remote control over the M10-P to adjust select shooting parameters or to release the shutter via the Leica M app. When working in live view, focus peaking is available to highlight edges of contrast for easier, more precise manual focus adjustment.
