I'm looking to acquire a set of more powerful strobes for classic wide-angle photos -- coral reef scenes, sunballs, schools of fish, large animals. So far, I've used the YS-D1s and z240s for my photography, and find them a little lacking at times in terms of illuminating power and recycling times.
I'll be using the strobes with a Nikon D810 primarily, though occasionally with a m4/3 setup (unlikely, as I keep this for lightweight travel & video).
What options are there out there for strobes significantly more powerful than the YS-D1s/z240s? I'm looking for:
- a wide beam angle for even illumination - 110-130 degrees ideally
- warm color. I usually shoot the z240 with the 4600k diffuser and much prefer it to the YS-D1s at 5500k. I would appreciate having a similar or warmer color of light
- round flash tube for more even illumination
What strobes should I research? I believe Subtronic and Seacam used to make more powerful strobes, but I'm not sure wether their current production units have any significant advantages oven the z240s. What about Ikelite? Any others? Would I be better of adding an additional 1-2 YS-D1s or z240s?
