The announced HF-1 strobe looks very good, maybe too good to be true when price/performance is regarded...
I am highly inclined to preorder two, as I am searching for strobes with more power as my current Z330s have, which come to their limits in bright sunlight and clear waters with the FF sensor (Sony A7R5; for the MFT cameras I was using previously, the Z330s were strong enough). The choice in filters/domes for warming up the light and the remote operation without additional flash trigger seem also attractive...
There is another, similar, strobe announced: the Apollo III from Marelux. The Apollo has three linear flashtubes (HF-1 has two), uses three 18650 accus (= 136 kJoule (kW.s) in total) while the HF-1 uses two 21700 accus (=137 kJoule). Apollo III delivers 800 flashes at maximum power (=170 Joule/flash), while the HF-1 delivers 375 (=366 Joule/flash). These numbers are probably somewhat smaller, since the flashes will probably stop operation before the entire power is drawn from the batteries, but they may be a good approximation...
=> >350 W.s per flash (at 2x power) is highly exciting, but is the heat sink capable enough to prevent burn-out of the flashtubes?
=> Does someone here have experience with preproduction versions of Apollo III and could compare to the HF-1?
