Well, the photographer

First of all, Nikon 50 F 1.8D lens has no motor, and it is impossible to autofocus D3 100 without a body motor.

For beginners, the most suitable lens is the hood.

The lens of 18-55 is not as bad as many novices think, but the optical quality is a little better than that of 18- 105, 18- 135, 18-200 (the zoom ratio is small.

Why do entry-level SLR cameras use this head? (The head of high-end SLR will be a little more advanced, for example, invincible rabbit's head is a red circle) Because this is a product designed by all manufacturers according to years of market experience, aiming at the most practical needs of novices, trying to balance imaging and cost, which can satisfy novices' mastery of basic photography techniques such as focal length and perspective.

The joint recommendation of major manufacturers really won't fool you. If it is really suitable for beginners to play SLR with fixed-focus lenses from the beginning, manufacturers will definitely introduce fixed-focus lens groups, uh-huh, just like Panasonic GF series and Sony NEX series.

Since the 18-55 lens is very cheap, you will be able to master certain photography skills after you get familiar with this "dog head" (the dog head can really produce large films), and you will know what kind of lens you really need. If you really need to upgrade, you won't feel bad if you remove this lens at a 30% discount. That is the biggest "saving".
