| The Sony A7 series has always been synonymous with high performance. Every new machine is a new standard in the industry. As the A7 series flagship top full-frame micro single camera - A7RM3, is a versatile product, designed and positioned On the other hand, the people facing the broader and more powerful performance, whether it is professional 4K HDR video shooting, or taking high-quality photos, this A7RM3 completes the task without pressure.  Micro-cameras have always had small size and high performance. The 35mm full-frame Exmor R CMOS back-illuminated image sensor with about 42.4 effective megapixels provides high-quality, low-noise image quality under all conditions. There is also a wide sensitivity range of ISO100-ISO32000 (still image expandable to ISO 50 - 102400), and a wide dynamic range of 15 levels at low sensitivity settings, making it excellent in different settings and shooting conditions. Overall performance, providing strong support for inspiration.  Here we will talk about this 42.4 effective megapixel back-illuminated Exmor R CMOS image sensor, which uses seamless chip technology and nano anti-reflective coating to effectively improve the light collection efficiency of the sensor, achieve higher sensitivity, and reduce noise. Performance and higher dynamic range, it also records 14bit RAW format output with rich color information from light to dark, and can also be shot in silent or continuous shooting mode.  Of course, the powerful sensor also needs other components to cooperate. The Sony A7RM3 is equipped with a new front-end LSI, which improves the image sensor reading speed by about 2 times. The new BIONZ X image processor increases the image processing speed by about 1.8. Times, facing the data of 42.4 million effective pixels, it is more flexible to handle, which can make the machine's imaging quality better, and the high ISO noise control ability is stronger.   In focus, the Sony A7RM3 uses 4D autofocus technology to cover 399 focal plane phase detection focus points with horizontal and vertical image range of about 68%. The contrast detection focus point is 425, which is 400 more than the previous generation. Achieve a larger area of coverage, making tracking focus easy to complete. This enhanced fast-mixing autofocus system can boost response speed by about twice the autofocus in low light conditions. Also improved eye control AF (eye) Focus on the camera), its success rate is about twice as high as that of the previous generation. Even if the subject is constantly moving, it can be effectively recognized and captured.  The newly developed shutter unit can achieve high-speed continuous shooting performance of up to about 10 frames per second, and can effectively reduce image blur caused by shutter vibration. This can greatly enhance the ability to capture or capture motion, and capture more. Wonderful moments.  In terms of image stabilization, the Sony A7RM3 uses a new 5-axis anti-shake system optimized for high-resolution shooting modes, which can compensate for shutter speeds of up to 5.5, reducing the shutter speed in low light conditions. And ISO sensitivity for a more pure picture. 
After talking about static shooting, it is necessary to talk about video, Sony A7RM3 can be super-sampled by 5K (15MP), shooting 4K high-definition video with rich picture quality, support 120/100fps high frame rate upgrade shooting, also has new HLG (Hybrid Log-Gamma) image profile, support for real-time HDR workflow. Built-in S-Log function, can capture high-precision live video with wide dynamic range, without color gradient processing, which is conducive to flexible post-production.  As the saying goes, the good horse is equipped with a good saddle. The Sony A7RM3 can be paired with the ZEISS Vario-Tessar T* FE 24-70mm F4 ZA OSS lens to achieve maximum performance under excellent optical imaging. This lens is widely acclaimed by Karl. Designed by Zeiss, it gives the lens excellent image quality. It achieves a constant F4 maximum aperture in the zoom range of 24-70mm. It has a wide range of flexible shooting purposes, portrait, street shooting, indoor, scenery, travel, field and other scenes. use.  The lens uses 10 sets of 12-piece 'Tiansai' optical structures, including 5 aspherical lenses and 1 ED low-dispersion glass lens. The material is solid, effectively correcting various distortions and aberrations, and compact lens structure. Achieve superior clarity and enhance contrast contrast over the entire focal length range.  The dust-proof and drip-proof design provides effective protection for a variety of shooting environments. Zeiss' unique T* coating and advanced optical design can suppress the reflection of the lens surface, thereby improving the transmittance and reducing flare and ghosting. Excellent image quality for the Sony A7RM3  Excellent optical image stabilization function, which can greatly reduce image blur caused by camera shake, especially in anti-shake mode, handheld night mode or shooting in dim indoor lighting. With this technology, it can be equipped with 5-axis defense. The camera system can easily capture clear low-noise images at night, indoors or under a variety of low-light conditions without increasing sensitivity.  Overall, the Sony A7M3 is a versatile full-frame micro-camera with a 42.4 effective megapixel back-illuminated Exmor R CMOS image sensor, 10 frames per second high-speed continuous shooting, and eye-controlled AF (eye focus) ), the new 4D autofocus technology, 399 phase focus and 425 contrast focus points covering 68% of the image area, 5-axis anti-shake system with 5.5 shutter speed, and video capture capability for 4K HDR recording. For users who are looking for small and portable high-performance machines, it is a good choice. Currently Sony A7M3 is priced at 20,399 yuan, plus 6,200 yuan Zeiss Vario-Tessar T* FE 24-70mm F4 ZA OSS lens that provides a low-cost 4K HDR shooting solution for small movie studios.
