What lenses are suitable for SLR or micro-single shooting video? Constant aperture and anti-shake focal length are known, but the functions of optical zoom and bayonet are unknown.

1. When shooting video, the SLR structure is not used at all, and the working principle of SLR camera is the same as that of mirrorless camera.

2. Anti-shake is basically of little use, because if you shoot a video, the camera will be fixed and put directly on the shelf. If the camera moves, the anti-shake effect of the lens or fuselage is not ideal, but you still need to get the stabilizer, fuselage anti-shake, lens anti-shake and even the electronic anti-shake processing function that comes with the machine. These are auxiliary, you can use some for the time being, but you can't expect to rely on them all.

3. The bayonet is basically a restrictive threshold for various manufacturers. Many times it is deliberately done differently, in order to restrict other manufacturers.

4.USM, Canon's name for lens ultrasonic motor, is usually not suitable for shooting video. Of course, many special video shots have no motors at all.

With a budget of 50,000 to 30,000 yuan, you are going to purchase those equipment. I suggest you simply list the items you want to buy first, such as fuselage, lens, shelf (or stabilizer, etc. ), microphone (may include bracket, mixer, etc. ), lamp (can include accessories, lamp holder, etc. ) and other extensions (such as rabbit cage, monitor, slide rail, rocker arm, follow-up focusing, etc.). ). Make clear which ones must be bought at present, which ones can be replaced and which ones are not bought for the time being, and then make clear the specific budget one by one. For example, I'm going to buy a fuselage of about 1 10,000, and I can have several alternatives, such as Fuji XT3 (the latest XT4) and Nikon Z6, and then I'll find the corresponding lenses according to my own needs to form three to five sets of combination schemes. Then if possible, you can look at the proofs one by one, compare the shooting quality, and understand the ease of use of each system. Because you are a novice,
