Hi,
I'm trying P-TTL wireless flash with an AF 540 FGZ and an AF 360 FGZ but seems that I found a bug when I would obtain a Controller - Slave set up. I do all the settings in the flashes and I use already this set up with a k-r, flash does the prelamp and fires only when I take the picture (then no SLAVE 2, but I already checked this).
Now see the behaviors:
EXPOSURE without flash 1/80 - f/2,8 - ISO AUTO at 400:
I'm in front of the coffe can and the external flash is on my right. Both 1,5m far from the coffee can. In the bottle you can see the refletions of flashes , in the coffee can the amount of light from both flash that take part of the exposure.
FIRST TEST. SCENE ANALYZE AUTO. Overexposed. In the viewfinder I see, in the meter section, 1/80 f/8.0 ISO AUTO (no info about ISO value then). Then I take the picture..... The picture instead it's taken at 1/80 f/2,8 ISO 400, then the exposure without flash !!!.
Check that the bottle has 2 reflections, and also the coffee can has a blade of light in camera direction.
SECOND TEST. PROGRAM. Overexposed. In the viewfinder I see, in the meter section, 1/80 f/8.0 ISO AUTO (no info about ISO value then). Then I take the picture.....The picture instead it's taken at 1/80 f/2,8 ISO 400.
Check that the bottle has 2 reflections, and also the coffee can has a blade of light in camera direction.
THIRD TEST. PROGRAM but with f/5,6 set by me, then in Av Hyper. Settings are 1/80 f/5,6 ISO AUTO. In the viewfinder I don't have info of the value that will be used. Checking the picture I see that the camera uses ISO 800. Check the shadow of the leaves in the wall.
FOURTH TEST. PROGRAM but with f/5,6 and ISO 100 set by me (time 1/80). Heavy underexposed. Now the flash in the right is strong but also the "controller" light takes part of the exposure.
FIFTH TEST. PROGRAM but with f/5,6 and ISO 400 set by me (time 1/80). Underexposed. The light is more balanced, the flash in the right is clearly visible but also the "controller" light takes part of the exposure.
SIXTH TEST. Take a k-r, use the same set up.
. PROGRAM (in AUTO is the same) ISO AUTO. In the viewfinder I see the same values that will has the picture. In the bottle you can see two reflections but checking the coffe can I can affirm that "controller" don't take part of the exposure.
IMHO this is a k-1 bug. Are you sure that RICOH's men read this forum?
Best Regards
