In this guest review, DP and Director Thomas Schweighofer takes a look at the Sigma Cine High Speed Zoom line during a documentary shoot with a RED EPIC-W Helium 8K. Please also read Graham Sheldon’s extensive review of both Sigma zoom lenses, which we published a few months ago. 

I recently had the chance to shoot a documentary project in the US featuring Austrian musician Dominic Muhrer and American Superstar Joshua Ledet. In order to achieve a better image quality in this particular project, I wanted to get my hands on some of the new Sigma cine primes, but at that point in time it was just too early to get a set. Instead, the folks at Sigma contacted me and told me to test their Sigma Cine High Speed Zoom cine line. I agreed but, being so used to shooting with primes, I didn’t expect too much.

Here is a quote from red.com:

“WHAT EXACTLY IS HDRX?

HDRx is a RED invention that is built into every EPIC and Scarlet camera giving the user an option for extended dynamic range when the situation calls for it… from 2 to 6 stops over native by preset.

HOW DOES HDRX WORK?

In a single camera, HDRx simultaneously shoots two image tracks of whatever resolution and frame rate you have chosen. The primary track (A-track) is your normal exposure. The secondary track (X-track) is a “highlight protection” exposure that you determine in the menu settings. You select the amount of highlight protection you need in stops… 2,3,4,5, or 6. Each stop represents a stop less exposure in shutter speed. Example… if you select 2 and your primary exposure is 1/48th sec, the X-track will be two stops less exposure at 1/192 sec. The ISO and aperture remain the same for both exposures.

During recording, the two tracks are “motion-conjoined”, meaning there is no gap in time between the two separate exposures. If they were two alternating standard exposures, there would be a time gap between the two tracks that would show up as an undesirable motion artifact. Both tracks (A & X) are stored in a single R3D. Since there are two exposures, the camera is recording double the amount of frames. For example, if you are shooting 24fps, the camera is recording 2-24fps tracks, the data equivalent of 48fps.* After combining the two tracks for playback you see only one 24fps motion stream.”
