How to choose Nikon d90 and d300s?

Portrait? If you shoot more beautiful women, you should still choose Canon EOS550D or EOS50D (you can choose the former if you want to play, because there are many fresh functions, and you can use the latter if you want to study hard). If you shoot more men, you can shoot Nikon. Of course, the gap between the two will not be too big. Good use can make a good film, and bad use is a bad film. Especially if there are more people using Nikon around, it is more suitable to choose Nikon. I only give Nikon the configuration here, because it is familiar.

There are many indoors, so I chose D300S for two reasons: focusing, D90 can't focus in the dark, and the viewfinder is not as big and bright as D300S. If it is indoors, the light will not be very good in most cases. D300S Focus and viewfinder are better at this time.

With lens, it is suggested that18-105+50/1.4 (the old version is more cost-effective, and 50/ 1.8 is also acceptable. Also, if the room is relatively small, choose 35/ 1.8 or 35/2.0, which is more expensive, although the latter is more expensive. Besides, I don't know what you mean by indoor portraits. If it's like a shed or a house, the lens is secondary and the light is primary. Professional photographers suggest some bigger studio lights. Those without batteries are cheaper, and those with batteries that can be taken out of the studio are much more expensive. This kind of lamp needs a soft box. If you are an amateur, you should have at least two overhead flashlights, one is second-hand (you can go to SB900 if you have money) and the other is SB 600-hey, look at Nikon's lights, good things and its name. ...
