Yesterday, I was watching World Series in a Common room (I just can't believe Rockies got swept) and couple guys popped in to test AlienBees B800. He had 4 of them with softboxes. Personally, I was impressed by the setup. They tested medium format and I had a chance to test it as well and I was satisfied what I saw.
But the question is: Will be something like this sufficient for 4x5, or 8x10? I'm more interested in continuous lightning, with a strobe options.
Is there any other systems I should consider? I plan to invest around 2500-3000 bucks.
