Excuse me, what lens is suitable for Nikon D40 or can give full play to its performance?

What lens a camera should be equipped with depends on two things: one is your budget, and the other is what you take with your camera. A shot discussion can last for a day and a night. Let me tell you briefly from these two aspects. Use telephoto lens to shoot birds, use wide-angle lens to shoot landscapes, and use fixed-focus lens to shoot portraits. You use the D40 fuselage, so I assume you are a junior photographer. I suggest you buy a wide-angle lens first. You can take into account the portrait and the scenery, and you can endure it first. Next, look at your budget. Personally, I think the more economical lens is AF-Snbsp；; Nicole nbsp；; 18-70 mmnbsp； 3.5-4.5 nbsp； ED is also the head of cameras such as D70, and there are many on the market. It costs about 1700 to find a second-hand one with good color (I'm not sure about the price, about 1000). The lens is of unknown workmanship, and it is a metal bayonet, which is not a little better than the plastic bayonet of D40. The aperture at the 70mm end is 3.5, and the aperture at the 70mm end is 4. Any dog head can take a good photo, and any cow head can take a garbage photo, depending on how you use it. If you are a camera, you can also use a condom first. 1 year later, you also know what you like to shoot and what you are suitable for shooting, and your photography skills have improved a little. It's not too late to choose the lens then. Don't waste money. In addition, you can go to nbsp [unscrupulous] nbsp, a professional photography forum. But be careful when you go in, don't be too poisoned. Ha ha.
