As you can see from the test above, the Profoto B10 flash was about twice as fast as the Godox AD400 at full power. At 1/2 power and lower, the Godox AD400 was about the same if not faster than the Profoto B10. However, when the B10 was placed into Freeze mode, the Profoto came up as the clear winner throughout the entire flash range.

On all three Nikon, Sony and Pentax cameras, it fired every single time, and the TTL exposures were pretty close to where we’d have put the exposure if we were doing it manually. I do enjoy the use of the modeling light on the AD-B2. However, you will not be able to see it effectively when shooting in bright conditions. Indoors and late afternoon light work though. You will not be bale to see how the light is at the actual power you may need to shoot at, but it will give you an idea of how it is going to fall across the subject. However, Godox learned from the AD200 and what they learned they applied to the Pro. On the AD200 Pro they improved the recycle time from 0.01-2.1s to 0.01 to 1.8s, as well as offering a greater choice of power ranges (1/256-1/1 in 1/10th stop increments instead of 1/128-1/1 in 8 stops). They also improved upon the design of the flash by adding a sunken LCD screen to the unit which protects the screen against damage in the case of being dropped or blown over. The only way to fix a mismatch like this is to reload the proper firmware image, but this depends on the device being able to recognize the firmware update request, and sometimes the correct/current firmware image you need is not available. Requesting the firmware from your retailer or Godox may be your only recourse.

Continue holding down the shift key through the spinning circle of white dots until you are in the blue advanced boot options window.

The AD-400 has reader options ranging from keypad only to multi-technology capability with or without keypads for multi-factor authentication. The multi-technology reader enables a gradual transition path from older credentials to the more secure and versatile smart or mobile technologies. But regardless of whether we were shooting within sync or at 1/1000th of a second, the AD400 Pro never missed a beat. Of course, most of us wouldn’t expect it to, but this is possibly the first time that anybody has tried it on a Pentax camera outside of the Godox test labs.Lighting modifiers such as softboxes, barn doors, snoots and beauty dishes are also readily fitted directly to the unit or the attached mount. New power button sequence prevents accidentally turning it on and wasting power (or burning anything) while travelling to or from a shoot We have not personally looked into Godox repairs, but we have heard many people claim they are disposable in the sense that you won't be able to have them repaired in the US. Profoto does have a warranty and a local repair facility so it's nice to know you can always send your gear to them for repairs in the event something malfunctions or breaks.
