Hi Everyone,
I have a 645Z which doesn't work as expected with their own Pentax Flash in HSS when using the FEC from the flash. I would like to know anyone else have their Flash on your DSLR notice this problem, or this is isolated to the 645Z only.
Here is the my part of the story:
Just want to write a little more details, and hopefully that would be helpful for those who are interested to use the Pentax Flash PTTL system with the 645Z
Setup:
- 645Z
- AF360FGZ II
- AF540FGZ II
Both allow you to setup the Flash in HSS mode as a Master Flash on Hot-Shoe or Controller mode.
The challenge I have with Flash compensation not working when making the changes from the flash
Example:
At 1/125 +1 FEC on the flash, it works. As soon as you start 1/160, the +2 FEC no longer kicks in.
At 1/125 +1 FEC on the Camera. Using 1/160 continue to accept the +1 FEC from the camera
Sadly, you can use -4 to +2 FEC from the flash if it works, on the camera, you are limited to -2 to +1
Translate this to a remote flash setup using my 360 II as controller and the 540 II as the remote flash. I am limited to +1 FEC from the camera, as the flash because of the HSS mode, which is very limiting, when compare to my Canon remote flash setup.
