2. Menus and information buttons become more sleek.

3. Cancel the DISP button and add the video quick switch button on the switch button.

4. Built-in stereo microphone with 64-level adjustment at the top.

5. New mode dialing.

6. Weight reduction of fuselage 19g.

In-machine upgrade:

1, a new generation DIGIC5 digital image processor.

EOS650D adopts DIGIC5 digital image processor, and its data processing performance is about 6 times that of DIGIC4. It can quickly process the huge image data of about18 million pixels obtained from CMOS image sensor, and further reduce the noise. High sensitivity shooting can also reproduce the details of the subject in detail without losing the sense of resolution. The noise reduction of DIGIC5 digital image processor improves the sensitivity of ordinary ISO by about 1. In addition, in-camera image processing adopts 14-bit (16384 color scale) analog-to-digital conversion, which can reproduce rich levels.

2. The sensitivity is improved to 25600.

The common sensitivity is ISO 100- 12800, which covers a wide range and can cope with various scenes. With extended functions, you can also choose ISO25600, and you can shoot at night and in a dark room without a flash. ISO automatic function can set the upper limit of ISO sensitivity, so you can take into account both high sensitivity and high image quality when shooting according to your intention. Seamless microlens is one of the image sensor technologies that support this high sensitivity performance. Good signal-to-noise ratio can be obtained by increasing the concentration of light. In addition, an efficient photodiode structure is adopted to reduce the noise of data transmission by the image sensor. The combination of advanced image sensor technology and digital image processing technology adopted by EOS650D greatly improves the image quality in high-sensitivity shooting.

3. Touch screen HybridCMOSAF high-speed focusing.

With the Touch Focus function, you can automatically focus by touching an object on the screen. By using the rich autofocus function, you can shoot a variety of styles. HybridCMOSAF can carry out phase difference detection autofocus on the image plane, and play the autofocus roles of "face+tracking", "free moving multi-points" and "free moving 1 point" in the effective area near the image center. After the phase difference detection autofocus completes focusing quickly, the phase difference detection autofocus performs accurate focusing. In addition, when using the touch shutter function, it is automatic from focusing to shooting, and you can shoot like a smart phone.

4, 9 o'clock full cross focus.

EOS650D is Canon's first EOS series 3-digit model equipped with full cross autofocus sensor. All autofocus points are cross-shaped and equipped with two sets of linear autofocus sensors corresponding to F5.6 On the basis of cross-shaped configuration, the central focus of high frequency is also equipped with a cross-shaped autofocus sensor obliquely corresponding to F2.8 beam, which can realize accurate focusing. The brightness of autofocus is -0.5EV to 18EV(23℃, ISO 100), which has a wide range and can capture the subject even in dim scenes. All focus points are equipped with cross-shaped autofocus sensors, which improves the autofocus accuracy. The subjects around the picture can also focus accurately and smoothly.

5, continuous shooting 5 per second.

EOS650D is equipped with a new shutter unit specially developed for it. Electronic control longitudinal focal plane shutter is adopted. The feature of the new shutter unit is that the front curtain of the shutter is composed of three curtains (EOS600D is two), and the increase of curtains disperses the burden of the shutter when it works. The durability of the shutter unit is greatly improved. The shutter speed can be selected from 1/4000 seconds to 30 seconds, and it is electronically controlled according to the selected shooting mode. You can also shoot at Gate B, and the flash synchronization speed is 1/200 seconds. When the sun is synchronized, you can use the aperture near the maximum aperture to shoot, and you can also use blur in portraits and other photography. In addition, it is equipped with a new structure that can drive the shutter at a high speed, and can perform high-speed continuous shooting at a maximum of about 5 frames per second, so as to deal with various moving objects in daily scenes and capture decisive moments. Continuous shooting l: about 22 (30), RAW: about 6 (6), RAW+L: about 3 (3). The number of continuous shooting sheets corresponding to UHS-I (ultra-high speed) with 8GB memory card is in brackets.

6.HDR backlight control.

HDR backlight control is a shooting mode, which is used to reduce the overflow of highlights or the absence of dark parts in an image during backlight shooting. Three images of underexposure, exposure standard and overexposure are shot continuously, and only the appropriate exposed part is extracted for image synthesis. Even in the scene with strong brightness difference, the natural atmosphere effect with balanced effect can be obtained, and photos with satisfactory brightness can be adjusted.

7, hand-held night scene mode.

Hand-held night scene mode is a shooting mode using the new function of "multi-shot noise reduction". The camera automatically selects the shutter speed that is not prone to hand jitter, and then takes four consecutive shots before synthesizing the image. You can shoot a night scene with low noise and high quality. When synthesizing images, the camera will automatically compensate for the dislocation of images and the jitter of people. Therefore, hand-held shooting can also shoot night scenes with less jitter and bright image quality.

8. Filter mode.

The creative filter has been upgraded from five options to seven options. Particle black and white, soft focus, fisheye effect, oil painting effect, watercolor effect, toy camera effect and miniature landscape effect are the most popular filter modes at present.
