Which professional camera has a blurred background?

Professional cameras should be able to change lenses.

If you can't change the lens, you need to install the Mini35 system to shoot such a "shallow depth of field" effect.

The first parameter of blurring depends on the size of CCD, and it is very easy to get this effect with a CCD of about 24* 16 mm under APS frame.

Second, look at the focal length-the actual focal length rather than the "35mm equivalent focal length". Only a lens of at least 50mm can have such blur.

Third, look at the aperture. Generally, F3.5 or larger aperture, such as 2.8 or even 1.8, is enough.

Of course, if the focal length exceeds 200mm, even the aperture of 4.0 will be blurred.

There are good and bad fuzziness. The blurring of beauty should not only be "virtual" enough, but also be "dispersed" evenly. This is related to the number of diaphragm blades. Generally, more than 9 apertures will be better, and more than 20 high-end lenses. It's too late to recommend the machine today. You can Baidu Hi me during the day tomorrow.
