hello #photography folks,

i need advice please. i am going to voluntarily shoot some portraits of ~100 people in quick succession for an esports event. problem is they have no lighting infrastructure, and i don't even own a flash

the portraits will be used right away in advertising and in any headshot display in broadcast production for the esports event the following day

what cheap, light (weight), mobile flash equipment would be good to look at, that's available in the Netherlands?

Sony a1ii + 85mm GM
