How about Sony 35 2.8? Is Sony 35 2.8 good?

In my personal opinion, this lens is very good, but it has an awkward aperture. The 35 focal length is known as the golden focal length for humanistic photography. Basically, all manufacturers will do their best to produce lenses in the 35 focal length. If you really buy a 35 focal length lens, the F2.8 aperture is actually very embarrassing. From the perspective of the 35 focal length photography range, assuming that the characters take up 1/3 of the frame when shooting people, the subject and the out-of-focus area need to be very strong. To highlight the three-dimensional sense of the subject, the 35 focal length has very high requirements for out-of-focus (if the quality of the Leica 35 focal length lens, the undisputed king of the 35 focal length, is used as a reference, out of focus is something that every Leica 35 lens owner cannot avoid The maximum aperture of F2.8 means that it is difficult to blur the background to an ideal state. No matter how good your skills are, this is an insurmountable obstacle. I personally think that when buying a 35 focal length lens, you should do your best to buy one with a larger aperture and better quality, because the 35 focal length lens is a golden focal length and is worth your investment.
