Why not respond to the true example I have given you - why did Oly abandon this idea in their DSLRs if it did work so well? Why did
ALL other manufacturers abandon the tradition TTL?
I cannot answer your Oly's Super FP sync question as I do not have any detail about it. For example, did Oly Super FP allows TTL metering? It did have OTF TTL, but in using Super FP high speed sync, does it have TTL metering as well or did it revert to manual fixed output?
The key to High Speed Sync as implemented in P-TTL is that it can have TTL metering at the same time; you can even have multiple wireless high speed sync TTL.
Quote: Nikon and Canon had multi-segment Off The Film flash matrix metering nearly 2 decades ago.
Sure, and both have abandoned the systems, even and particularly in their most expensive bodies.
Quote: As for wireless control, it is just like remote controller of any electrical appliances, how come you have to relate this to the P-TTL? At least Minolta has wireless TTL auto flash also in the 90s.
Because this is the most efficient way for TTL metering for multiple wireless situations.
And don't insist on that it is my imagination. I have all the manufacturers agreeing with me. Do you?
