1/22,000 is the t.5 time it would take from a non IGBT flash to get a 1/7000 t.1. The two systems you mention are IGBT controlled. I have no idea why Profoto would publish t.5 times on an IGBT system?? If I want to play that game Einstein would come out about 1/20,000 t.5 . . . or as high at 1/30,000 if I want to ignore solid performance in order to create a real fast number. Would yawl rather see that number? Would it make you think my product suddenly became light years faster?
I have to disagree that 1/8000 t.1 and 1/12,000 are equal on IGBT systems. 1/8000 t.1, if you measure it and understand the technology, will come out abut 1/15,000 t.5.
This is an opportunity for the industry to clarify this so users can compare and understand. I will do that . . . if others want to keep manipulating numbers . . . they\'ll be gone in 60 seconds.
I have published Lumenseconds for years while others keep talking about meaningless guide numbers and assigned new non-dictionary definitions of the word range and any number of other marketing hypes.
