JVC ANNOUNCES GY-LS300 4KCAM VERSION 2.0 FIRMWARE UPGRADE
New Features Include JVC Log, Cinema 4K Recording Formats, Unique Prime Lens Zoom

​
WAYNE, NJ (August 4, 2015) – JVC Professional Video, a division of JVCKENWOOD USA Corporation, today announced the Version 2.0 firmware upgrade for its GY-LS300 4KCAM handheld Super 35 camcorder. The upgrade adds a “JVC Log” mode that practically duplicates the look of film, plus new Cinema 4K and Cinema 2K recording modes, a unique Prime Zoom feature that uses the camera’s innovative technology to allow zoom capabilities when using prime lenses, and a histogram. Free for all current owners, the upgrade will be available in September 2015.

With the new JVC Log mode, the GY-LS300 delivers wide latitude and high dynamic range – up to 800 percent – to rival the look of film. The camera’s Super 35 CMOS sensor delivers a higher contrast ratio between dark and bright areas within the frame without saturation while providing details within highlights and shadows. V2.0 also adds 4096 x 2160 Cinema 4K and 2048 x 1080 Cinema 2K recording modes at various frame rates, each with a 17:9 aspect ratio for digital cinema presentations.
Prime lenses have a fixed focal length, but the GY-LS300’s new Prime Zoom feature takes advantage of JVC’s unique Variable Scan Mapping technology, which was created to electronically adapt the active area of the camera’s image sensor to provide native support of various lenses when paired with third-party lens adapters. When used with a Micro Four Thirds (MFT) prime lens, the image can be adjusted between the maximum scan area and minimum scan area using the camera’s zoom rocker. As a result, the camera can deliver 2.3x maximum zoom for HD or 1.25x maximum zoom for 4K. The new Prime Zoom feature can also be used as a lens extender for zoom lenses.

Version 2.0 adds a histogram display, which is useful for checking the exposure by showing the brightness distribution of the image. The function is accessed through a convenient user button, and the range can be set to provide top and bottom limits. Beyond a histogram, V2.0 adds a color matrix adjustment, spot meter for setting exposure values, and black paint setting to precisely adjust color temperature of master black. Additional performance and streaming enhancements include a new 70Mbps recording mode, which makes it possible to record 4K on economical Class 10 SDHC/SDXC memory cards.

“We listened to our customers and made sure this firmware upgrade delivered the features they wanted, as well as recording modes specifically designed for the 4K digital cinema market,” said Craig Yanagi, manager of marketing and brand strategy, JVC Professional Video. “The GY-LS300 will also have the unique ability to use a prime lens as a zoom lens, which gives shooters even more shooting flexibility.”

Designed for cinematographers, educators, documentarians, and broadcast production departments, the GY-LS300 is the flagship camera for JVC’s new 4KCAM product line. It accommodates a variety of workflows with the latest advancements in 4K imaging and efficient encoding for seamless workflow integration. It also includes a built-in HD streaming engine with Wi-Fi and 4G LTE connectivity for live HD transmission directly to hardware decoders, the Wowza Streaming Engine, and the ProHD Broadcaster server powered by Zixi. With support for various streaming protocols including RTMP, the cameras can stream directly to content delivery networks (CDNs) like Ustream and popular Web sites like YouTube.
 
"With the new JVC Log mode, the GY-LS300 delivers wide latitude and high dynamic range – up to 800 percent "

What is the "800%" referring to?

I would guess 3 stops more DR, 200% = 1 stop, 400% = 2 stops and 800% = 3 stops. But that is just my "guess" if 100% is the base from previous version, otherwise they might even mean 4 stops...
 
Yes that would be nice to see. But if there is __ stop(s) improvement, JVC should use that metric.
 
This might just save this camera.

It's a very fine body, but the DR and the awful highlight rolloff just killed it.

If this LOG addition increases the DR and smoothes out the highlight rolloff....THEN this camera will be a contender.

Considering the language doesn't say "800% more", I would assume 3, not 4.
 
I am very curious what this will do with the image. With the excellent price point and formfactor I realy wish the best for this camera.
But the image is to digital for my taste so if firmware could improve that a big plus.
Beware because there can be a log profile but DR is limited in the sensor afaik so don't expect more than 12 stops in total. Sensor whas rated at 10,5 if I remember.
Can't wait to see what will happen.

Would be great if you let us know you findings Jim Martin. Thx in advance.
 
Marketing hopes you'll never ask that question....800% more than.... what?
Or....'practically duplicates the look of film'...I guess that means everything except looking filmic.....for this one

Cheers....Tye
 
Is this camera 8 bit internal recording, and if so what's happens to the video when you squeeze things back into looking real?
 
JVC addressed 2 of the 3 major gripes I had with this camera.
1.No real exposure monitoring. Update adds a histogram. Would've preferred a waveform but it's a decent substitute.
2. Lackluster highlight handling. I'm assuming "J-Log" will help rectify this.
The 3rd gripe I had with this camera was lack of high frame rates. Didn't see that in their updates. (Maybe down the road?)
I initially had high hopes but felt kinda let down after owning the LS300 for a week. I had no regrets returning the camera despite it getting these much needed upgrades.
Looking forward to the release of the Ursa Mini. Hope BMC can deliver on their promises.

Wow, you purchased and returned. This is exactly why a company shouldn't release a lackluster product. I guess we can't knock Canon for releasing any products too soon. LOL!

I bought one back in May, against my gut feeling about the camera. I guess I just wanted to move on up from my AF100. Plus, I figured some of the 'issues' were due to it being in the early development stages.
The comparison to the Panasonic has already been debated to death on this this forum, but in my opinion the AF100 feels more professional. (If that makes any sense!)
It felt like I was giving up features just to get a little better image quality.
 
"This is exactly why a company shouldn't release a lackluster product."

Like the T5i? Many feel it is step backward even within its own heritage. But back to the JVC. Stick to metrics (stops) that people can understand. And if higher frame rates are coming, pimp them prematurely like BMC or Panny (Vlog).
By the way, when folks talk about highlight handling, are stops/absolute dynamic range really the pivotal err..bit? I mean, whatever the DR, the reality is we will bump up against it. Maybe the issue is what happens then, essentially the implementation of "proc amp" type of processing. Similar to quality vs crappy audio limiting...

By comparison, the Sony F5, F55 or FS7's S-Log2 claim up to 14 stops of dynamic range, which is said to have 1300% dynamic range, versus the 1000% of the original S-Log. As such, JVC's log of 800% would appear to be rather lackluster.

Yeah... but the FS7 with the 4k add on is, what, $12K? That's 3-4 times the price of the LS300. Not really a fair comparison.
