Four Things You Need To Know Before Buying A2 Or Citi100Pro

The AD100Pro/ Citi100Pro and Profoto A2 are exclusively off-camera flash. One key advantage of off-camera allows you to add additional light from various angles and move your light. Therefore, both units are able to move anywhere surrounding the object of your shot, at any height, angle or distance. 

In fact, the Citi100 Pro is the rebranded version of the Godox AD100Pro flash unit. Meanwhile, both units are manufactured together so that each version offers the same high quality and specifications. As the Citi100Pro is the same achieving the top pick in 2018 by PixaPro. It also allows utilising the same modifiers and accessories that would be compatible with the AD100Pro, such as Godox 2.4GHz Triggers.

It allows us to offer detailed and professional advice and support throughout this period. From here, you can generally figure out the key main strengths and weaknesses of these brands and also choose the appropriate flash.  


How much is the power? 

The most frequently asked question when buying flash devices is how much power they might be able to produce. Like all lights in the AD series, the AD100Pro’s name makes it clear that will deliver 1100Ws of power from a small package. Similar to the Citi100Pro/ Ad100Pro, the Profoto A2 also has the same outstanding power. 

This having been said, the AD100Pro/ Citi100Pro is capable of supplying 360 full-power flashes of a single charge, whilst the Profoto A2 supplied 400 flashes. The Profoto A2 will keep your shoot going for a little bit longer compared with the AD200Pro/ Citi100Po.

How much quality is produced from these flashes? 

The AD100Pro/ Citi100Pro can deliver 1/8000 high-speed sync, plus control of multiple flash setups via an optional 32-channel wireless transmitter. Moreover, the Godox team released the Godox AD100Pro/ Citi100Pro with a 9-steps power adjustment. From there, you will feel flexible and creative through a diverse range of channels and power adjustments. You will also benefit from this flash with its wide range of light shapers aspiring for more possibilities in your creative photography journey. With a high-capacity 2600mAh 7.2V rechargeable Li-ion battery powering the CITI100 Pro, you get recycle times of 0.01 to 1.5 seconds.

The battery of the A2 is the standard Profoto A series MKII power cell with a two-hour recharge time. Moreover, you can use the original A battery but offers fewer flash cycles. The A2 delivers 100Ws of power at 5800K, which is slightly warmer than other Profoto lights. The flash duration is superb at t.1 value of 1/350s at full power can effectively freeze motion. However, it could be better since it can run operations of the t0.5 value at 1/1,200s. Those who photograph active sports or freeze motion during events.

To be honest, both units are simple and more powerful with the smallest size. If you looking for flashes for a wedding setup, you can start to invest in the Citi100Pro/ AD100Pro and A2. It is perfect for the photographer who has to travel to shoot events or weddings. 

How is the capable of modifier lighting options? 

The AD series is well-known and built-in with the TTL Auto-EXposure and High-Speed Sync (HSS) support. It allows the Citi100Pro/ AD100Pro to work with several well-known camera brands including Canon, Nikon, Sony, etc. Therefore, it is an ideal device for hurried shooting situations without wasting your waiting time to achieve a nice exposure such as wedding photography, gathering, etc. 

With the AD100Pro, you can be able to add a bonus to the Godox AD-E2 bracket. It allows you to attach your flash head to any light stand, umbrella, or softboxes. Meanwhile, the AD100Pro slots into your existing kit without necessarily purchasing any extra accessories. Moreover, the Magnetic mount system enables you to swap modifiers quickly and easily with very little fuss. For example, if you attract the AK-R1 accessories kit, your flash might be able to maximize the capabilities of its flash head. While to create a Bowens S-Fit flash head, you will need an S2 Bracket

Like all flash in Godox brands, the AD100Pro/ Citi100Pro is built in the same Godox 2.4G wireless system. The CITI100 Pro is also compatible with the Pixapro ST-III, ST-III Plus and ST-IV flash triggers.

How much are its weight and dimension? 

The Godox AD100Pro is the smallest off-camera flash offered by Godox. Its size is about the size of a typical drink can. It is the best option for carrying on location. Because it weighs only 524g and is portable enough to put in your pocket or camera bag. 

Moreover, the flash AD100Pro/ Citi100Pro has two lots underneath. So, you can move it about to get the most out of the strobe whether you are holding it in your hand or using an umbrella. Both units of the two brands release with an LCD panel display. It clearly shows the state of strobes so you always have control of the group lighting setup. Take A2, its LCD screen shows current power as well as indicates remaining battery life and the current colour temperature.
