Really great What about the settings for the zoom?
★★★★☆A Google User· Mar 30, 2015
I DID love it... But a simple checkbox choice between zoom or non-zoom would have been much better than "set the same guide number for each zoom position.". Yeah, nah. Suggestion: a list: First entry in the old style - a simple slider for GN - max/min defined by user. Followed by a number of (standard and) user defined entries for zoomable units. This would allow those of use with numerous strobes to easily select between the ones we can't zoom with the old GN slider, and the ones we can zoom by selecting a different strobe definition from the list. Preferably also allow us to define the focallenght for the various zoom GN rather than have to pick from an assumed set.

Relatively new to flash photography but in my rather limited experience 8 know the distance of the flash to subject it's the power setting for the flash that's variable. I realize you can move the sliders to get the distance you want but wouldn't it be easier to set the distance as a fixed value and have the flash power as the variable?

Other screens Using an LG g3, and can't go to any other screen, saw the entry about lower left button, but that doesn't work on this phone.

You can only have one custom guide number. Deleting others won't let you add more. What's the point? Hey thanks for your reply :) adding more doesn't work it just replaces the first one you added.
