The LCD dot matrix control panel, including the on-off button, is located on the side of the AD400Pro, which is much more user-friendly than the AD600Pro, where the on-off button is located on the bottom, frustratingly underneath the handle. Lighting modifiers such as softboxes, barn doors, snoots and beauty dishes are also readily fitted directly to the unit or the attached mount. The Godox Witstro AD400Pro All-in-One Outdoor Flash has 400ws strength power, 0.01-1s recycling time, 12 continuous flashes in 1/16 power output, 40w LED modelling lamp, 380 full power pops and stable colour temperature (which changes within +-75k over the entire power range in colour temperature mode. Whilst the AD600 Pro is a wireless flash, powered by rechargeable Li-ion Batteries, an AC adapter is available to create a mains-powered flash head. This AC adapter is great for studio work as it means that neither you nor your work is restricted by battery power on longer shoots. By offering the choice between mains or battery-powered, the AD600 Pro becomes an even more versatile, lighting option for all shoots!

We have tried to cover all of the features, the specifications, the pros and the cons of every flash unit in the AD range so far, including the AD100 Pro. So, let's start with the newest of the AD series. AD100 Pro Despite three of us shooting the single strobe that day, that was turned on the entire time, I didn’t have to dip into my Novoo to recharge the battery at all. At the end of the day it was still showing 3 out of 4 lights on the charge indicator This ability to overpower the sun comes from the massive 600Ws of power that this light can produce. This light has a power range of 1/256-1/1 in 10 increments, a recycling time of 0.01-0.9s, as well as sporting TTL and HSS capabilities. The Bowens adapter is solid, can be left attached permanently, can still be used with the supplied reflector and all fits inside the case complete When we initially set out that day to test the XPro-P trigger, we hadn’t planned to have the AD400 Pro audition for us at the same time. We had originally hoped to use the AD200, but we ended up not doing. The reasons why we didn’t use the AD200 will be explained in the XPro-P review in a few days, but it forced us to use the AD400 Pro.Godox has confirmed to me that tenth stop adjustments will remain a “Pro” model only feature, so it will not be coming to the AD200, AD360II nor the Godox range of speedlights. Of course, they hadn’t told us about the new round head speedlight then. Godox hasn’t said yet whether or not that one will offer 1/10th stop adjustments. In summary, though, it feels like a good solid light, and it seems to have all the features that were added to the AD600 Pro in a recent firmware.

Overall, the AD400Pro and AD600Pro are both amazing portable flashes that perform very well in both indoor and outdoor settings. On speaking with Paul, he felt that it was a similar sort of power output to his older Godox AD600BM. We put this down to the better bulb placement on the AD400 Pro.

To learn more about the difference between these two flashes, as well as the pros and cons of this flash, read our AD200 vs AD200 Pro comparison blog. As I mentioned, the AD400 Pro essentially offers the same features as the AD600 Pro with the new firmware, but with a little less power. One of the features recently added to the AD600 Pro in this firmware was 1/10th stop adjustment options. With both units featuring Godox’s 2.4GHz X-System Radio Receiver built in, setting up a shoot has never been easier. This similarity in power seems about right to me. When I compared the AD600 Pro to the AD600BM a few months, I did see about a 1/2 to 2/3 of a stop increase on the AD600 Pro when using the same modifiers. And the AD400 Pro is about 1/2 to 2/3 of a stop less powerful than the AD600 Pro. Pros

Offering 100Ws of power in a compact body (sizing in at just 120x76x76 mm, of the size of a can for scale!), as well as 390 full-power flashes from a single charge of its rechargeable battery! This makes the AD100 Pro perfect for traveling photographers, event photographers, as well as any on-location shoots, due to its wireless, portable and lightweight nature.

No 1/3 stop power adjustment option on the strobe itself (but you can still do 1/3 stop increments from the trigger) The design and construction of the carry bag itself is sturdy, and the componentry fits snugly and securely into the pre-cut foam inserts. Great TTL Auto Flash Compatibility|: Godox AD400Pro is Compatible with Canon E-TTL II, Nikon i-TTL Autoflash, Sony, FUJIFILM, Olympus and Panasonic TTL Autoflash System. With Master＆Slave Function, AD400Pro Can be Used in Combination with Godox TTL Camera Flashes, TTL Outdoor Flashes, etc Supports Accessories with Adapter Ring: With the specially designed new Godox mount to install lighter and more portable accessories which can be used in combination.

A screen grab from the XPro-P review video (coming soon) lit by the AD400 Pro modelling light inside a 4ft parabolic softbox. 1/50, f/8, ISO800. The process of adjusting to TTL, Manual, or Multimode is straightforward, and it is easy to customise the settings and play around with different lighting effects – these can all be adjusted using the side control panel on both units. 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. It also comes with a set of screws and an allen key for fixing the included Bowens Mount adapter ring to the unit. Normally when I shoot TTL, it’s when I’m forced to bring my camera along to family events. I’ll set my camera to aperture priority with -2EV compensation to underexpose the ambient and pop an SB-900 in the hotshoe bounced off the ceiling set to +2EV to bring the subject up where I want it.

First Impressions

Due to its size, the AD100 Pro is a great light to hold and maneuver as you need. Because it is so light and small, it is perfect for squeezing into tight spaces and angles to achieve the perfect lighting. It can also be simply held in your hand and moved around accordingly which isn’t possible or can be uncomfortable with bigger and heavier lights. The colour appeared consistent throughout the power levels – at least, certainly more consistent than the AD200 and AD360II – and the recycle times were very short, even when shooting high speed sync.
