One camera is a Hacked GH1 at 100mb, the other is a GH2. One camera is cropped to 2:35.1, the other actually has the anamorphic lens. They are mixed almost exactly 50/50
What this short video is about is taking all three cameras to the extreme. Is this a particularly useful test? Probably not. But there are always a few people out there that demand the best high ISO performance and will use whatever it takes to capture the shot.
To set this up, we have to keep in mind that the Panasonic cameras will only go to their max ISO settings when in shutter priority mode with an electronic lens. This does not allow us to use the same lens on both brands of cameras, which is typically a place we don’t want to go with these types of tests. Also, there is no specified ISO on the screen while shooting in shutter priority with Ev set to +3, so we have to test against stills in order to ascertain the ISO the camera is shooting at.
Relative ISO. The GH1 at ISO 3200 is equivalent to the GH2 and 7D at around ISO 6400. You can see in this test it has quite a bit less chroma noise just from being at half the ISO of the other two cameras.
Here’s a test from last week with just the gh2 and the 7d – unfortunately again this is less comparable as one lens is f1.7 and the other f2.0
So why bother with this $130 wireless system? Most people know they need a Sennheiser EW100 as at least a baseline wireless system. But now in 2011, many people are buying DSLR cameras for video and spending less than $300 for excellent video cameras that have terrrible audio. Most first inclinations are to add a completely useless shotgun to the top of the camera.
Even if this system isn’t the greatest, it’s still 100x more useful than tiny shotgun 7 feet away from your talent.
So how does it fare? For the price, it is certainly usable for web work. The line output is fairly low, but most of these DSLRs have AGC so it’s probably not going to matter. It captures a very compressed and bass-y version of the human voice, but for no budget run and gun style web videos I could see it being perfectly adequate. No, its not going to work over long distances. No, its not going to work with any other interference in the area, but it is going to work better than the built in mic on your dslr and it will work better than a silly shotgun sitting on top of the camera.
Vitality announced on his website today that he is able to downgrade unhackable gh1s to version 1.32. This will allow any GH1 to run the GH13 bitrate and battery patches!
Hurry up and buy a body for $399 before they disappear!

So in this second test with the new lpowell patch for Vitality’s GH1 Hack, we test Color, Dynamic Range and Fine Detail without overloading the codec on the GH1 to the point of crashing, but at the same time have a full range of light to compare the two cameras. Both were at their lowest ISOs which provides the most amount of Dynamic Range. At the same time both cameras used the Smooth Profile.
Here’s a quick little vlog testing the differences between the GH1 and GH2 (exact same settings) at ISO 1600 and 3200 respectively.
The GH2 has come quite a ways forward from the GH1 in terms of processing high ISO video.
Here is the first video in a new series of tutorials for the Panasonic LA7200G anamorphic adapter. We’ll be diving into its flaws at multiple focal lengths and apertures.
This first video focuses on the 14-140 lens and using the adapter wide open from 17mm to 70mm
