24- 120 is still a half-width fuselage, so you must have a flash. If you don't buy a flash, it won't be enough in the dark. Because the height of half the fuselage is not very good.
If you want to match the fixed focus, it is suggested to consider 50 F 1.4G head, or 35 1.4G head and 35 1.8G head used in Quan Huafu. The prices are 2000+, 8000+ and 3000+ respectively, and you should choose according to your own economic strength. Close-ups can also be taken, which is easier to bring the environment and suitable for documentaries. The full lens is also selected to upgrade the Quan Huafu fuselage in the future. It is not enough to take half a wedding photo. After all, airframes are very popular in Quan Huafu now, such as D6 10 machines.
If you choose the lowest-priced fixed focus, you can choose dx's 35mm 1.8G head, or Quan Huafu's 50 1.8G head, or 50 1.8d head, which are all of good quality. The price is 700- 1000+, which is more affordable. Half of the fuselage does not need to consider the 85 focal length for the time being. Unless you have spare money, you must buy a full-body one in the future. People with focal length above 70 are still beautiful.
I hope it will be useful to you, and hope to adopt it. Thank you.
