(I know that this word is often used as a slang towards people, and my question is not about this meaning.) What I'd like to know is its meaning in the context of photography. Does it mean "kit lens"? ( A "kit lens" is a cheap lens that comes with the purchase of a camera.) I often see 狗头 listed with (the name of) a camera such as in the examples below: 50D+狗头 ("50D" is the name of a Canon camera) 新手550D狗头试片 佳能550D 狗头套机 我的鸡头和狗头 (And what is 鸡头? Does it mean "camera body"?) Thank you!
