How would you all rank the different brands of lights?
Sure in the highest level there's Broncolor followed by Profoto
and in the still pretty good there's Elinchrom and Hensel.
In bargainville there's AlienBees.
How would you place newer brands like Godox?
You title mentions "systems"...Profoto, Speedotron, Elinchrom, Paul C. Buff, Broncolor, all have an entire system behind them, of varying degrees of scope and price. There's a lot in the way of light-shaping tools that I consider part of a flash system, like grids, metal reflectors, variable beam-spread reflectors, mylar diffusers, metal screening material diffusers, background light reflectors (clam-shell or half-shrouds, whatver you wanna' call 'em), barn doors both 2- and 4-door, Fresnel spots, etc.. A lot of the ancillary stuff is where Speedotron shines: there's a LOT that can be done with metal honeycomb grids, and mylar and metal diffusers and barn doors added to lights.
Flash is complex; these days there is the new-generation High-Speed flash-synch options. I wish
@ronlane would weigth in here. I've looked at some of the new, MIC gear. For people who need one or two flash units, and high-speed flash synch for outdoors shooting, etc.. then Godox and some of the other Made in China stuff looks VERY good to me, for a low price. If a person wants to be able to shoot flash at 1/2000 to 1/4000 outdoors at f/1.4 or f/2 or f/2.8, etc.. then the newer, MIC,
new-era-feature-set stuff looks good.
Older studio flash stuff is mostly that: studio-centric, indoor-centric. Godox has some VERY appealing stuff. I've shot mostly old school studio flash from DynaLight,Speedotron,Photogenic,Norman, Sunpak; in monolights Alien Bees, White Lighting Ultras (Buff line), JTL, but all only a small bit; in speedlights, Vivitar, Nikon, Sunpak,Crown, Canon. I dunno...there's a LOT of stuff out there!
I see new-era-feature-set AKA
high-speed flash synchronization-capable daylight outdoor flash as being entirely different from old-style "studio" flash.
If I were buying ALL-new today, I might look into a high-speed flash syunch-capable monolight setup.
