back-focus

[sean]

I did not understand that words, what does the back-focus mean

they are the comments from www.fredmiranda.com

"The 2 D2H's that I had were back-focused with any lens,"

"The images were soft, most back-focused and exposures were way off even though I used a hand-held meter and strobes with Pocket Wizards"

What it means in my understanding is that the camera focus something behind the object you intend to focus. By the same token, front focus means it focused on something in front of the intented subject.

我和FAD理解一样,就是焦点靠后了,通常所说的跑焦.

if that's the case, I would probabley say, the camera/lens is sensitive on any slightly move. He was shooting the sports.
