How is the camera function of Canon 550d SLR camera compared with more than 3,000 cameras?

In terms of battery life and ease of use, 550D is not as good as DV. First of all, this is because the sensor of SLR camera is much larger than DV, so the energy consumption and calorific value are both larger than DV. After 20~30 minutes of continuous operation, the battery can't eat, and the sensor will overheat (the worst result is that the sensor is used up or even burned out). Then it's also a problem that you can't keep focusing. That is, after shooting, if the subject moves back and forth, the machine will not focus automatically and must focus manually. Therefore, if shooting close-range motion, 550D is very troublesome, and it is only suitable for shooting tasks with fixed machine position and fixed subject position, such as close-up and lens division. Finally, there is the problem of pickup trucks. Picking up with the microphone that comes with the 550D fuselage can only record mono, and the sound of the machine running can be easily recorded as a video file (even Nikon D3 100, which supports autofocus tracking all the time).

From the final shooting effect, the video effect of 550D is overwhelmingly better than DV. First of all, the large sensor brings much lower pixels per inch, so the picture color is purer and the reproduction is better; The large sensor brings a larger actual focal length and aperture of the lens, which makes the depth of field shallower, that is, the background blur is higher, which is desirable for close-up and split-shot videos. Finally, the file is output. Many DVs over 3000 don't even support 720p HD video, but 550D supports 1080P (although larger video pixel files are larger and require higher memory card capacity).

So if you want to say that there is no comparability, think about it. For example, if you want to surpass the effect of DV in an all-round way, you must have an external microphone, be familiar with manual focusing, and the machine should be fixed. In other words, from the results, 550D has the potential to surpass DV, but it depends on how you use it.
