First of all, you should pay attention to the sensor inside. At present, the sensors of professional camcorders are all composed of 3CCD or 3CMOS, most of which are 1/3 and a few are 1/2. The larger the sensor size, the clearer the picture, but the higher the price. The advantage of CCD is high picture definition, but the disadvantage is high power consumption; The advantage of CMOS is low power consumption, but the disadvantage is loud noise, and the image is not as good as CCD. Secondly, the lens, German lens is the best, especially carl zeiss and Leica lens, but most camcorders are integrated with the lens body, but some are not, such as Sony HVR-Z7C, PMW—EX3 and so on. In my opinion, the price of most camcorders will not exceed 50 thousand. My suggestion is that you can buy Panasonic's 153mc and 173mc, but the price of 173mc is that you must buy p2 cards and Sony's v 1c, z 1c and z7c.
