[QUOTE="hark, post: 752064, member: 13196"] Just a little info on flashes/speedlights - when looking to purchase a flash, keep watch of the guide number. The higher the guide number, the further the light will reach and the more light output available. If you are interested in knowing more about that, [URL="https://imaging.nikon.com/lineup/dslr/basics/24/02.htm"]here's a Nikon article[/URL] that explains it. So when comparing the guide number of your flash with a Nikon flash, you are pretty much in the ballpark of the SB5000 which is Nikon's most powerful flash. Godox makes a couple that are comparable plus the Godox is a step up in terms of overall quality.
