My 220ex just isn't doing it anymore, its great for fill flash, its very helpful on camera when I've got reasonably good natural lighting to begin with. So I'm looking to upgrade soon and I'd like to get started with a basic strobist thing. I'll be getting an ABR800 within the next few months but in the meantime I'm looking for something cheaper and more portable.
Sigma 500 DG Super
Sunpak 383 and wein optical slave
Sunpak 433 and wein optical slave
I'll be using whatever flash i get off camera triggered by my 220 on camera most often. Im leaning towards the sunpaks as they are cheaper, but if it would be enough of a benefit I'd suck up the cost of the sigma, are there any others i should be looking at? which flash would you all choose?
