Does anyone have experience with any of the MK-320 TTL flashes on Fujis? I've been debating on getting a Nissin i40 for a while now, but ran across a couple of different models of the MK-320 on Amazon. At ~$80, it perks my interest.. What I'm looking for is a travel flash that I can bounce around or remote with a TTL cord. Would be interested if anyone know how it performs against a Nissin i40. Thanks!
