I wanted to move this discussion out of the knowledge-base thread... so....
I'm curious. What's the appeal of this flash? It seems to have less raw power than the Sigma EF530 DG or the Metz 48 AF-1, yet costs more than either of those. And those have HSS and can be used as a wireless P-TTL slave using Pentax's 4-channel optical system. (And if you don't need those, the non-super Sigma is significantly cheaper and still more powerful.) But I'm really just starting to learn the details here, so perhaps there's something I'm missing?
