I have another gear related question. I know the hvl-f58 has 3 groups of flashes with ratio control, but the manual was a little vague on a couple of details:
- How many flashes can you have in each group?
More than one (except the control flash, the one that is on top of camera and set to CTRL+). If you want to have more than one flash on each group, set them all to "RMT" or "RMT2"
- The ratios seem a little odd. So, you can choose I believe 1, 2, 4, 8, 16 as the ratio for a group, but what does that mean? Is it for instance, at the 4 setting, 1/4 of the power from the TTL exposure, or is this the actual power used for the flash with no TTL input?
Say you set to 1:2:8, then the second one (RMT) is twice as bright as the master (control), and the third one (RMT2) is 8 times as bright as the master.
- Is the commander/control unit (HVL-F58) controlled by the grouping as well? So, if you wanted to have only the HVL-F58 as a controller, with no input on exposure, are you limited to just 2 groups since you would have to turn off the controller group?
Assuming you have more than one HVL-F58, and there's one on top of your camera, and you only want to use it as controller. You can set the flash ratio to something like "-:2:8" (instead of "1:2:8"), and the control flash would only output the control signal.
