Can a camera of about 3000 yuan shoot this effect?

Don't! 3000 flagship machine? Will have these effects. But the effect will be very poor, and the entry SLR will cost 3000? How about adding a lens?

Is the portrait clear and fuzzy? Is it a SLR? A large aperture fixed-focus lens can produce good results.

First one? Look, starlight is hexagonal light? Usually Canon's SLR? See how well the noise is handled? Must be a SLR? Nikon's SLR is usually octagonal light?

Previous picture? Does it mean 3? But? There will be a lot of noise.
