What is an SLR?

什么是单反？

Bring a cable release and a digital SLR camera.

带上一载电缆连上数字单反照相机。

Emergence of low-cost "prosumer" digital SLR cameras.

低成本“ prosumer ”数码单反相机的涌现。

Smaller, lighter and usually quieter than equivalent SLR.

比同级别单反更加轻便。

Ah, well then I'd recommend a nice entry-level digital SLR.
