HyperSync vs High Speed Sync: Nikon D7100 v3.416

This is a look at how PocketWizard HyperSync performs relative to native Nikon High Speed Sync on my Nikon D7100 camera and Nikon SB-900 flash using the brand new as of July 2014 version 3.416 of the PocketWizard firmware for the MiniTT1/FlexTT5 system.

All pictures taken with a Nikon D7100 with the Sigma 18-35mm f/1.8 lens, f/16, ISO 100. Flash zoom was 105mm. The front of the SB-900 was exactly 3 feet from the wall. The camera was on a tripod to the left and behind the SB-900 angled to the right. The SB-900 was manually set to fire at full power, since with this type of flash that causes the flash burst duration to be the longest, crucial for HyperSync to work well. "Highest Energy Mode" was used for HyperSync.

So, it looks like HyperSync has been improved greatly in 3.416 for the D7100 and SB-900, 1/8000 second at full power is a full 2 1/3 stops brighter than Nikon High Speed Sync.

Test conducted July 19, 2014 using the PocketWizard 3.416 firmware on both the MiniTT1 on camera and the FlexTT5 on the SB-900 flash.

On July 20, 2014 I added a second section doing the same test, but with the SB-900 flash head zoomed to 17mm to better show the HyperSync gradient.
