原文摘錄如下: Unfortunately Panasonic didn't share that technology with Olympus, and the E-P1 uses essentially the same focus system as cameras such as the E-620, meaning that it feels sluggish even compared to most compacts.
The focus speed certainly feels a little (but not a lot) faster than the CD-AF on, say, the E-620, thanks we'd imagine to the faster TruePic V processor and optimized lenses, but it's not a patch on Panasonic's system, and in low light at the long end of the zoom is pretty painful. You get autofocus with Four Thirds lenses too (using the optional adaptor), and we're assured there won't be a single Four Thirds Zuiko that won't AF (and it looks like there'll be no performance hit either; it's slow whatever lens you use).
