It could also exhibit some black speckly noise which was largely cleared up in a firmware update. What a difference a year makes. Panasonic has indeed taken all that was good about the HPX, fixed the shortcomings, and even refined it a bit more for news usage. These chips use what Panasonic refers to as U. Operationally, there are a few things I noticed as well, aimed at making the HPX more usable for its intended news market. One feature is inherited from the larger cameras, which is the ability to extract or trim portions of a clip without having to use any other hardware devices or a computer.

And in all the internet chatter about these two, that one factor keeps being brought up again and again. I bet it went something like this: INT. Several blue-suited Panasonic executives stand proudly around their new HPX An EX3 on a tripod stands in the corner.

The Panasonic exec smiles knowingly, as he begins to explain the advantages of the HPX Another Panasonic exec points to the form factor of the two cameras. Frustrated, the Panasonic broadcast manager steps forward. It is the new standard in broadcast. At this point, most of the Panasonic staff commences pulling their hair out in frustration.

One steps forward, clearly at the edge of his patience. The is a full-size camera, with a wireless mic slot, records four channels of audio, and is the main camera of NBC News! A quick huddled discussion ensues What could Panasonic do? Finally, one of the engineering staff steps forward and offers a suggestion. Probably not, but the question at the end there is one that needs to be addressed.

Is it true? I then set about exploring the technical comparisons between these two. Instead, I was more interested in finding out the extent of the improvements, and what the realities are, versus the claims that are made. SKEW This was my first test. So how is the skew in the HPX? Did they "fix" it? So I set the two cameras up side by side pointing at the freeway, zoomed in to full telephoto on the EX3 and matching as best I could the framing on the HPX, and shot speeding semi trailers on the freeway at a degree angle.

It was actually a pretty ideal test, at least as indicative as the skew-off. Now, remember that skew is worse the more telephoto you zoom in, so I was trying to get it at its worst. And it is perhaps these two subjects that have kept audiences doggedly persistent in pointing out that the Sony cameras have larger chips. So how does the HPX stand up? But match and surpass it, it does. The HPX especially after the firmware update was competitive, but not quite as clean and when the black speckles would hit, it would indeed be noisier than an EX1 or EX3.

So, how about now? The HPX is cleaner. Not dramatically, but noticeably. It was easy to see the difference on the monitor, and when I pulled in the chart footage and split-screened it and magnified it, yeah, the HPX is cleaner than the EX3. Well, it is. At equivalent gain levels, the HPX shows less noise and more brightness as you can see in the sample video above. But, because the HPX is about a half-stop more sensitive in p mode you can actually use -3dB of gain on the HPX, versus 0dB on the EX3, and have the same level of brightness but a substantially lower level of noise.

Assuming you want to stay at 0dB or even -3dB of gain, in p mode the HPX wins the low-light battle. However, when you start pushing the gain, the Sony appears to have a cleaner gain circuit than the HPX does. The solution with the HPX was to increase the detail coring a couple of notches. The HPX is a solid performer that matches its bigger-chipped competition in imaging, and easily outstrips it in performance in most other categories.
