Yongnuo 560 II vs Godox Mini Master 160 ?

Just curious which one is brighter ?
1 unit Yongnuo 560 II vs 1 unit Godox Mini Master 160
In case same ISO, Speed etc ..

Here's the Godox Mini Master full spec

Again, which is brighter ?
And share your opinion, if you would buy some of them which one you'll buy ?


Regards,

According to the specs, the Mini Master 160 has an ISO-100 GN of 43, vs the 560's GN of 39. So the Mini Master is very slightly brighter.

The Mini Master is AC only vs the YN560 being battery only (without hacks).
The Mini Master has a modeling light but none on the YN560.
The Mini Master can be adjusted from 1/1 to 1/8 power, the YN560 from 1/1 to 1/128 power.

Neither unit has a built-in mount for modifiers such as beauty dishes, softboxes, etc. However, the Mini Master has a built-in umbrella clamp, while the YN560 can utilize an L- or S-bracket to mount modifiers.

I might be inclined to buy some mini-master's for background lights or hair/rim lights; I could probably make a snoot that slips over the head and gets retained by a thick rubber band or velcro. The inability to a softbox or beauty dish, or overpower bright sunlight, would make them less desirable to me for main lighting.

I wouldn't buy a 560 Mk II at all. I do own and might buy more YN560 Mk IV's to pair with my YN560-TX, allowing me to adjust the flash settings from the camera. I would use these with Godox S-Type brackets to mount umbrellas and Bowens-compatible modifers.

Any opinion, ??

Yongnuo 560 II has GN 58 ISO 100
Godox Mini Master has GN 43 ISO 100

So that Yongnuo must be brighter ? Is it true ?

GN is not useful when comparing very different flashes. Light output is much more useful. Mini master has it at 160 WS, which should be enough for small to medium size studios. Yn560 doesn't list light output, but from what I read even the brightest speed lights don't go beyond 60 Ws or so , so master is probably 2x brighter than YN560. YN560 still can be perfectly adequate for small studios, and has the portability advantage.

But watt-second is not a measure of light output. Watt-second is a measure of power consumption. This is only a useful specification when comparing strobes with identical circuitry, flash tube and reflector. Even if you know the impact of the particular reflector used you cannot calculate exposure value from watt-seconds; you can only estimated it based on empirical evidence.

Ref: http://www.imaginginfo​.com …t-Is-A-Watt-Second/3$1043

But you can determine the GN for a strobe based on empirical data, at least with a specific reflector. Changing reflector size, shape, and in some cases even room size and color, will change the GN of a strobe. And this might be a valid exercise if you plan to use a combination of strobes and speedlights, so you have an idea of how to layout your lighting plan before double-checking with a meter and/or taking test exposures.

Guide Number is a measurement of actual light, measured at the subject and specified as the maximum distance a proper exposure can be captured at ISO-100 and f1.0. So GN is actually a usable specification for calculating exposure, and accordingly, the brightness of a flash or strobe (in terms of light falling on the subject). And knowing GN we can use the inverse square law and knowledge of the exposure triangle to calculate appropriate ISO and aperture at a given distance between the light and the subject.

But GN is not necessarily constant on speedlights either. Most speedlights have optics that can adjust the pattern of light emitted to provide wider coverage for wide angle lenses and narrower angles for telephoto, and the amount of light that winds up on the subject is adjust accordingly.
