YN560IV

For my first bikepacking warming trip I’ll be carrying my Einstein 640 Studio Flash to analyze how many times I’ll need it’s full power and how convenient is to carry this flash & it’s battery pack on a bicycle… maybe two small & cheap YN560IV mounted on a flash bracket is all I need when combined with a leaf shutter camera (Fujifilm X100s) with a 1/1000s flash sync.

I used a previous version of these Chinese manual flashes and never had a problem with them. This new version adds a master mode (or a radio transmitter unit) built into the flash that controls remotely the flash power (and flash zoom length) of 3 individual groups of YN560III & IV flashes.
