Question about which Yongnuo flash to add

[clarkking]

Hello! I haven't posted here in a long while so long that I had to create a new account because I don't have access to my email address for some reason.

 

I'm looking for some advice regarding the addition of 1 or 2 Yongnuo flash unit to my existing Canon 580EX2's (3), for use as off camera units for speedlight studio work. My existing 3 580EX2's have worked great over the years but I need to add some lights but do not think that additional high priced canon units are necessary. I use pocket wizards (plus 2) as triggers.

 

I have been researching the Yongnuo flashes and it seems confusing to me that they have many models, for example using google I still cannot find what the newest model is! What I would like to know is which Yongnuo flash matches the power output of the Canon 580EX2 or is more powerful? I am also having trouble finding the PW Plus 2 units now as they have been replaced with newer models, but for this I am considering adding PW plus X triggers.

 

Any help is appreciated,

 

Thank you!
