Most novices buy cameras directly from camera kits, such as 18-55mm and 18-135mm car camera lens in the APS-C format. The lens of a kit car has two characteristics: one is to cover more practical focal lengths, which can meet basic shooting needs; the second is to be cheaper and more cost-effective.

The shortcomings of the lens of the kit car are also obvious: 1. Without a large aperture, the blurring effect is not good 2. The wide-angle is not wide enough to shoot a large scene

The lens of the first car that most users come in contact with is the lens of a kit car. Because of this, the lens of a kit car is not enough. It mainly depends on what you need to shoot. Let me briefly summarize the lens of the kit car for everyone. Use: I like to travel, I want to be portable, I want to shoot daily, and vlog videos need to be upgraded: I want to take wide-angle shots, I want to blur backgrounds, I have blurry requirements, I need a telephoto car lens, I want to shoot stars, etc. Starry sky, portraits, architecture, etc., it is recommended to buy some better car lenses

First, the lenses of different bayonet cars are not necessarily universal. Some bayonets can be used through the adapter ring, but in general, the lens of an SLR car can be used on a micro single, and the lens of a full-frame system car can be used on an APS-C or M43 format, otherwise can.

The lens of the car should be the same as far as possible, which can improve the versatility of the car DVR lens of different specifications in the later stage. It mainly refers to the lens of the car is divided into the lens of the full-frame car and the lens of the APS-C car. For example, Canon SLR lenses include EF lenses (full-frame) and EF-S lenses (APS-C). The full-frame car lens can be used in the APS-C body. Otherwise, it can be successfully installed and cannot be used normally. So when we buy a car lens, we always say that buying a full-frame car lens can reduce the trouble of replacing the car lens in the future, because the lens of the APS-C car cannot fit the full-frame lens.
