Nikon D700 hangs 28-70 F2.8D, and D90 is ready to be used as a tourist plane for traveling abroad or climbing mountains.

Are you going to get into D90 or do you already have it? If you plan to enter, it is recommended to enter high-end notebook computers or micro-batteries or single batteries. It's meaningless to enter the D90 again at this time, especially since you already have a complete set of machines, even if they are second-hand.

If you already have it, it is also useful to come here and have a look. The latter is more suitable between 16-85 and 18-200. After all, the focal length range is wider, which is more suitable for travel and general use. 16-85 is a good start, but there is no 18-200 cost-effective here. Of course, 18- 105 is enough if it is only used as a standby plane or a tourist plane. After all, the price is only a fraction of the first two, the imaging quality is similar to that of 18-200, and the focal length is equivalent to that of 16-85. The telephoto end has advantages and is obviously more suitable.
