	Newly Developed 33MP1 Full-Frame Back-Illuminated CMOS Image Sensor. The new α7 IV's 33.0 megapixel Exmor R CMOS image sensor provides outstanding performance and excellent quality in both stills or movies, with its high-speed readout capabilities giving you fast data capture for your images as well as highly accurate color reproduction at low noise levels!
Flagship-Level Image Processing With BIONZ XR™. The α7 IV features an image processor that is many years ahead of its time. The latest advances in hardware and software provide cameras with unparalleled performance, delivering high quality pictures while also allowing for fast continuous shooting speeds to capture every moment you want them on film!
	Cinematic Color Science With S-Cinetone™. The new S-Cinetone color, developed for Sony's acclaimed FX9 and created with today’s content creators in mind. It produces rich colors that are more natural than those found on most cameras with fresh eyesharpness straight out of camera while retaining plenty of post production options so you can bring your vision to life however desired!
5-Axis Optical Image Stabilisation. The camera's high-precision stabilisation unit and gyro sensors work together with image stabilization algorithms to achieve up tp 5.5 steps of shutter speed compensation, so you can take advantage on its 33MP sensor for maximum resolution performance!
	Fast Hybrid AF, Evolved. The Sony 4D FOCUS system is an innovative wide-area contrast detection AF that has been improved even further to provide faster, more accurate tracking for both video and stills. With 7596 phase detect points across 94% of the image area (as compared with 6000 in previous models), this new fast hybrid model delivers amazing performance! .
10-frame-per-second7 continuous shooting with fast buffer release The high-capacity buffer memory and speedy BIONZ XR processor allow you to shoot up 800 frames8 at 10 fps with AF/AE tracking, thanks for the α7 IV's superior hardware!
	Sony's Smart AI Based Real-Time Tracking. Sony's unique subject recognition algorithm is able to process spatial information in real time using color, pattern (brightness), and depth data. AI software tracks human eyes or animal faces with extreme precision while they're being filmed by a camera - no need for manual adjustments! .
4K 60p Movies With Smooth, Natural-Looking Capture. The Sony α7 IV has been designed with a new image sensor and wide dynamic range to produce high quality movies. The highest frame rate available is now up 4K 60p, allowing you full pixel readout without binning which results in smoother videos of fast moving subjects!
	7K Oversampling For Beautifully Expressive, Richly Detailed Images. The camera is able to record in 4K up-to 30 fps, making it perfect for capturing fast action. You can also choose from different frame rates that are tailored specifically towards your needs - whether you're looking at high quality or just wanting something slower paced! .
