bjdavey, could you please elaborate on what exactly has improved, and how you tested it?
Here is my methodology (abridged, please see previous posts for more details). I will appreciate it if you try it:
Use mode X in the camera, with the flash set to P-TTL, no compensation. Take one shot of something at a reasonable distance with the flash pointed straight ahead. Take another shot of the same object, this time with the flash slightly tilted (enough to make the flash think it is tilted, showing the appropriate tilt indicator on the UI). Compare the shots.
With my K-5II and Sigma 610 Super, the second shot is consistently much brighter, typically overexposed, than the first shot, which is usually spot on, i.e., well-exposed.
I will do some more testing to find out if there is
any change, since several people here do testify there is indeed improvement. I hope that this time it is more than wishful thinking (which sometimes accompanies firmware upgrades...).
