Re: No DFD with Olympus lenses

Hi Jim,

Same here--I had to dig into the Panny technical references to learn what the DfD system actually does and how its implemented. When they rolled it out they uploaded focus tables for their existing lenses to the cameras via firmware but since then their new lenses have the data on board, dispensing with FW updates for every new lens.

I suspect they could develop the data for any system AF lens and choose not to, for obvious is slightly cynical reasons. The E-M1s at least seem fairly agnostic as to the lens brand--applying PDAF to all brand in the modes its used (although, I think the Pro teles have faster focus motors in general). CDAF-only Oly cameras won't get top focus performance from Panny lenses compared to their DfD bodies. We're at a bit of a crossroads with the two brands at the moment.

Cheers,

Rick
