Another key difference for the M vs the A for the KRP series is the location of the settings for Drive Mode.
In the A it is outside in the Options. What that means is that you can still calibrate in the ISF Modes and set Drive Mode to 2.
In the M series, it is in the Picture Options. Also in ISF Modes the Drive Mode is fixed to 1. That means that we cannot use it for 50Hz stuff.
One of the advantages is for Astro (which needs Drive Mode to be set at 2), you can use the brighter ISFccc modes in conjuction with the Drive Mode for brighter image for the As and this is not so for the Ms.
The brightest u can get with proper gamma tracking on the 600Ms without the ISF modes is 33ft/L with Pure Mode. The brightest you can get with the ISFccc modes with proper gamma tracking in the 600Ms is 48ft/L. Thats quite a difference.
The only option for the people who have Ms for higher light output for Astro or 50Hz material is to use User mode but the gamma and colour errors are not as good as the Pure modes.
The As (KRP500) shd be able to go as high as 50ft/L in ISF modes while still being able to set Drive Mode to 2. Thats plenty bright for sports.
Drive Mode, ISFcc, A & M series, Gamma tracking..... you are a techno party animal!
Heavy tuning stuff. Many thanks for the comparisons and sharing your knowledge on this

Time to digest this stuff over the long weekend................
