What does SLR stand-alone mean?

SLR camera refers to a single-lens reflex camera, which is what we often call a "single-lens camera". Single SLR refers to a SLR camera with only the camera body (excluding the lens). When you buy a SLR camera, you usually need to buy the camera body and lens. If you only buy a camera body, it's called a SLR.

Since the SLR does not contain lenses, it is suitable for photographers who already have a certain photographic foundation or have a certain lens inventory. In addition, some photographers will buy SLR to match different brands of lenses to achieve richer creative effects. But for beginners, it will be more difficult to buy a SLR, because it is impossible to shoot normally without a lens.

What are the advantages and disadvantages of SLR?

The stand-alone advantage of SLR is that the price is relatively more economical. If the lenses have been used together, it can meet the basic photographic needs. In addition, in some shooting scenes, such as tourism shooting, a single-shot SLR is lighter than adding a dimming lens to the camera body. However, the disadvantages of single-shot SLR are also obvious. Because there is no lens, it is impossible to improve the image quality and imaging effect with the lens. Lens quality is also one of the important factors that determine the image quality, so the shooting effect of single-shot SLR is weaker than the combination of camera body and high-quality lens.
