Here are (very) technical details: http://164.195.100.11/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=/netahtml /search-adv.htm&r=2&f=G&l=50&d=PTXT&p=1&S1=(((pentax+AND+flash)+AND+TTL)+AND +SLR)&OS=pentax+and+flash+and+TTL+and+SLR&RS=(((pentax+AND+flash)+AND+TTL)+A ND+SLR) As a matter of fact I have some photos, where there was an object near and the other (where the focus was set) far. The one that was near (defocused) was overexposed, while the other was exposed perfectly. In this situation "normal" TTL would took in cosnideration light reflected from near objects and as a result we would have underexposed main object(s). Pretty smart. In this matter P-TTL works similar to Minolta's ADI system, or Nikon's 3D matrix flash metering. It's a pity, that Pentax didn't included this information in advertising materials about AF360 and P-TTL enabled bodies. BTW, AFAIK not only FA but also older F lenses provide distance inormation.
