Following on from yesterday’s review a number of questions arose around using the Nikon SU800 in conjunction with the Pocket Wizard Mini TT1 and Flex TT5 units.
So, I thought I’d add a ‘follow up’ post which will hopefully go some way to explaining how all these fabulous bits of kit can work together and make our lives alot easier; and to make sure everyone is catered for I’ve included information on shooting in both Manual and Aperture Priority Modes:
Aperture Priority Mode with SU800
- Mini TT1 on Camera
- Speedlight in TTL and Flex TT5 in Group ‘A’ on light stand
- SU800 in hotshoe on Mini TT1 with Group ‘A’ set to TTL
Using the SU800 we can now simply increase or decrease flash power as you can see in this series of images where I have adjusted the Flash Exposure Value (EV) by 1 stop each time:

Shooting in Manual with SU800
- Mini TT1 on Camera
- SU800 in hotshoe on Mini TT1 with Group ‘A’ set to ‘M’
- Speedlight in TTL and Flex TT5 in Group ‘A’ on light stand
*Note: Whatever mode you are shooting in, be it Aperture Priority or Manual, the flash itself must always be set to TTL in it’s own control panel. This doesn’t mean it’s actually shooting in TTL as the ‘real’ mode of the flash is what you have it set to on the SU800 Commander Unit ie ‘M’, ‘TTL’ etc…
With this set up I can now adjust the power of the flash from the SU800 Commander Unit as opposed to physically adjusting it on the flash itself or having to alter my aperture to allow more or less light from the flash into the exposure:

Multiple Lights
The advantage of using the Nikon CLS is that we can control powers and modes of multiple flash from the camera position by using, for example the SU800. With these new Pocket Wizard units we can do the very same thing but unlike before, we are now no longer reliant on ‘line of sight’ to send and receive the signal as it’s all done via radio waves.
So, looking at this example here we have two lights…
Again, the flashes themselves are in TTL mode but this time as we have two lights, one of the Flex units has it’s switch set to Group ‘A’ and the other has it’s switch set to Group ‘B’.
Now, on the SU800 controller I can control both lights independently of each other , and to show that here’s a series of photos where on each one I have altered the power of one or both of the flashes:


To Summarise:
If you have an SU800 or a Speedlight that you can put into ‘Commander Mode’ such as the Nikon SB800 or SB900 then:
1) When shooting in Aperture Priority Mode you can adjust the Exposure Value (EV) i.e +1.0EV, +2.0EV and so on…
2) When shooting in Manual Mode you can adjust the power of the flash to taste i.e 1/16, 1/8, 1/4 and so on…
3) If you have multiple lights you can control them individually in whatever mode you want (Manual, TTL) by choosing a Group (i.e. A, B, C) using the switch on the side of the Flex TT5 and then set up the same Group’s on your SU800 or Speedlight.
One final thing and that is to mention the Pocket Wizard AC3…
In short this little unit will be able to do all that the SU800 above can do but at a fraction of the cost and size.

Hope that all makes sense and goes some way to answering the questions that were posted in the earlier post, but as always if there’s anything else you want to ask or comment about then feel free to make use of the comments section below,
