I must be one of 'em because I haven't got a CLUE what CDAF is so I must not need it. heheheh

CDAF= contrast detection auto focus

When you use the optical viewfinder, the camera uses pdaf: phase detection auto focus. When you use live view (which is all the time on micro 4/3s), the camera uses CDAF.

Mark II of the 14-54 is optimized for cdaf. Same for mark II of the 50-200. Mark I of these lenses is not. Given the fact that olympus' dslrs use liveview more and more (with the introduction of video, for example), and that a huge segment of their current dslr offerings will be replaced by m4/3s, some lenses that have not been optimized for cdaf are getting a lot cheaper.

If as recently as 2 years ago someone told that I could buy a 14-54 mark I for less than $300, or a 50-200 for less than $600, I'd never believe them. Those are excellent values.
