Micro Four Thirds Mount With A S35 Sensor? Yes! JVC GY-LS300 4KCAM Camcorder

November 14, 20149 Comments


Looks like JVC has been hard at work creating new cameras and listening to users on features they would like. That info helped create the JVC GY-LS300 4KCAM. Specs aside the foundation the camera is built on is unique. The GY-LS300 has a S35 sensor and a Micro Four Thirds mount. Yes Thats not a typo! JVC states that the sensor clears the mount so you can with an adapter put full frame lenses and APS-C ones too and take full advantage of the S35 sensor. Have PL lenses? Get a PL to MFT and you are set.

If anything I find this very cool and I like the innovation. MFT mount is the most  versatile mount I have ever used. Practically any lens with an adapter will work and more smart adapters are coming to market like the Canon EF to MFT Speedbooster and smart adapter from Metabones.

My first impression was. JVC just made the 4K S35 AF-200 I wanted. Okay well maybe thats a stretch…

The GY-LS300CHE features a JVCKENWOOD AltaSens 4K CMOS Super 35mm image sensor. When the camera is used with MFT, Super 16 and other size lenses, JVC’s proprietary Variable Scan Mapping feature will maintain the lens’s native angle of view. This gives filmmakers the flexibility of using widely available MFT lenses as well as high end cinema lenses. The unique combination of the MFT mount, the larger Super 35mm image sensor and Variable Scan Mapping give the camera nearly limitless lens options.

How this works in the real world is the big question. Being able to shoot with native MFT lenses too and have the same field of view as a GH4 is crazy. Something I have to see. I’m also interested in the viewfinder and LCD screens. Yeah thats important too right? Have to see what your shooting.

Advanced IP Network Communication and Streaming

The GY-LS300CHE features JVC’s latest IP communications engine giving you remote control and monitoring of vital camera functions from a tablet, smartphone, or computer anywhere in the world. Live streaming is possible in HD or lower resolutions, depending on available bandwidth. JVC’s Advanced Streaming Technology (AST) includes Zixi powered Forward Error Correction with ARQ, delivering high quality streams even under challenging conditions. And now RTMP protocol makes it easier than ever to deliver your live streams to content delivery networks such as USTREAM and YouTube. Just press one button and you’re streaming to the world!

These streaming features could come in handy too.



Check out the handle. Reminds me of a Cinema EOS. It’s removable and the body looks like a small FS700. The JVC GY-LS300 has some features that the big boys have like built in ND filters but hey what’s the deal! Get to the codecs and frame rates already!

It even comes with that shotgun mic. All for $4,450.00. Not bad but the only thing missing is what does the image look like. We shall see. If I find some footy I’ll update this post.

In HD the camera is capable of 4:2:2 at 50Mbps.

XHQ 422 mode:1920 x1080/59.94p.29.97p,23.98p(50Mbps) and 4K Ultra HD recording (150 Mbps, 24p/30p) to SDXC(UHS-I Speed class3) card. It does have HDMI 2.0 for 4K out but again I don’t know if it’s uncompressed or not and one 3G-SDI: 1 x BNC out.

The GY-LS300 is a cool camera and one I would like to try out. JVC has been in the local broadcast market for some time and with this camera it brings in interesting features both filmmakers and newsmakers like. The price is pretty good for a 4K video camera with a large sensor but will it perform? For only a grand more could a guy who doesn’t need 4K be better off with a Canon C100 MKII? Maybe but again we need to see some samples. Another camera this moves in on is the GH4 with YAGH. I say with YAGH since the GY-LS300 has XLR inputs and SDI / HDMI outs. The GH4 is a fantastic camera but it is a hybrid and using a hybrid for video can be a pain. This is a good entry for JVC and I hope it’s a good one. Lets see some footy!

More info on the GY-LS300.

GY-LS300 4KCAM S35mm Camcorder
The GY-LS300 records to non-proprietary SDHC and SDXC media cards in a variety of image formats including 4K Ultra HD, Full HD with 4:2:2 sampling, SD, and Web-friendly proxy formats. It features JVC’s 4K Super 35mm CMOS sensor combined with an industry standard Micro Four Thirds (MFT) lens mount. JVC’s unique Variable Scan Mapping technology maintains the native angle of view for a variety of lenses, including Super35, MFT, and Super16. As a result, lens options for the camera are almost limitless.
“ The combination of a Super 35 sensor and MFT mount is a brilliant solution to accommodate the largest variety of lenses and adapters without compromising image quality and lens characteristics,” said Edgar Shane, general manager of engineering, JVC Professional Products. “It gives filmmakers flexibility to use high-end cinema lenses or affordable glass to capture 4K/HD footage.”

    Looking forward to your update on this, especially vs. the C100 mkII! All in one ENG/ filmmaking tool!

  2. Hmmm… bit more than $4k vs $8k for the FS7, so nearly half the price!

    I bet it will not come anywhere close to matching the Sony FS7 in terms of what it offers, but just maybe….. it might turn out to be good enough to consider at half its price? Will be keeping an eye on this, especially as it is Micro Four Thirds mount (which means more savings for me, won’t need to get Sony E mount lenses as I already own plenty of m4/3 lenses).

    • Erik Naso says:

      I wouldn’t expect FS7 IQ but if it is better or equal to a GH4? I think I would pick the JVC instead for video. We shall see.

      • Well… that would still be about more than 2 or 3 times the price of a GH4, so if it is merely equal to the IQ from the GH4, I don’t think I could go for this JVC camera. (especially as in many ways it would still be behind, such as no 96fps FHD!)

        • Erik Naso says:

          The GH4 needs an audio interface so add that in and a way to connect it like a cage or add a YAGH for a much better audio and video out option. Miro HDMI is the pits! It’s all about the image in the end. Also the JVC has a S35 sensor. Thats worth a lot and very versatile since it will crop for MFT format too. Again it’s all about the IQ in the end.

  3. SC says:

    It will be interesting to see which native M43 lenses work on the S35 sensor without scan mapping and if there is any benefit to this. The Olympus 45mm covers an APS-C sensor. I imagine the Voigtlanders and other fast primes would too. Regardless, very interested in this camera.

    I thought you might like to know the much awaited first footage of the upcoming JVC GY-LS300 is available.

    This is shot with a preproduction model of the camera :

    Hi Eric–tons of insights on this site. Can you tell me what lenses auto focus on the JVC GY-LS300?

    Much respect, Mark
