My JVC LS300 Review (with files for download)

Ever since the first DSLR started shooting video there has been one dream, the functionality of a camcorder with the sensor and lens mount of a DSLR. All in an affordable package.
This might be just that.



JVC has lended me the camera for a few weeks to try out. What Im mostly interested in is if:
  • Its as good as the specs makes it out to be.
  • If it can be both a true Run n Gun camera and something for cinema.
  • If it is the ultimate camera for vintage lens junkies

Regarding the specs, here is what cought my eye.
  • MFT Mount
  • S35mm Sensor
  • 4K
  • 4:2:2 HD
  • Log
  • Prime Zoom
  • External Controls
  • Built In NDs
  • XLR



First Impression
It is light and small but doesn't feel cheap or flimsy. I would say it feels just like theses DVX type camcorders always does. Not 5D rugged, but solid, maybe a bit more solid than a FS100.
Setting it up was super easy and intuitive, I mean its a camcorder... its great.. its like riding a bike

Getting all the features I want like zebra etc went fast, they where all exactly where you would suspect them to be.

The ND wheel feels nice, so does most of the controls and buttons. The audio wheels are clickless, thats a tiny complaint but no deal breaker.
The first lens I tested was a m4/3 12-42mm. Its the kit lens from my GFs GM1. It worked and surprisingly it only had some vignette at the long end in s35 mode. In other words its both a normal MFT zoom and a s35 wide angle.
It also turns out that there where sensor size stops between s35 and MFT!



Files for download!



Here are some files for download so you can play around with them.
One is a test of the Dynamic Range. It was shot in s35 with a m4/3 kit lens so there is severe barrel distortion, but no vignette.
The other is a portrait of Gunpowder with a vintage Yashikor 55mm
My advice for grading is to treat it as Rec709 and don't push the shadows to much. The mids and highlights can take more of a beating.


DR test Ungraded
No highlights blown, sky is preserved for the sake of the test.


With a quick grade


Gunpowder ungraded


Quick Grade 1


Quick Grade 2

I hate to say it, but thats all I have had time for so far, more t come.
Meanwhile, here are some pics.

Handle is nice


Nice and light


The wheels are a bit loose, but lovely to have.


External controls rule!


Size comparison to an old DSLR



Some Footage


We where heading out for a walk in the park today and I grabbed the LS300 for a test run.
Unfortunately I underestimated the wind, which was quite strong, and brought a low weight tripod.
So prepare for some shaky footage.


I used a dumb adapter and two Canon EF-Lenses, the 35mm f2.0 and the 24-105mm f4.0.
This resulted in no aperture control and no stabilization… yeah, even more shakes.

The reason for this was simple. I tend to shoot vintage glass, soft filters and use heavy grading.
Lots of people like myself find it appealing. But some want a clean and digital, sharp look.
And just to get that out of the way I used “L” glass and just a mild grade.
Next time we will go full “Instagram”.


The shooting experience was great. Its easy to use, everything works nicely.
Again, its a camcorder, like riding a bike.


Screen is a bit though in the sun, but using the EVF helps. Not the best EVF either but totally usable.


I also uploaded a version with grain to Vimeo.



On the way home I saw some beasts and though it was a great opportunity to test the Prime Zoom.
For those that dont know what it is, the camera uses its ability to use different cropped sensor sizes for a zoom without loosing resolution.


Using the prime zoom is awesome. Just push the zoom rocker and its smooth.
It also turned out that it works in 4K. No where near as much of a zoom but still.. its cool.

The only real negative I see from using it is moire, but aren't we all used to that...


This is at 105mm (roughly 155mm FF equivalent)



And with Prime Zoom





The review might take a while. Meanwhile here are 5 reasons I decided to buy one for myself.

Thanks. Hopefully JVC will continue this line and other camera makers will jump on board --- jump back on board --- this obvious body style.
 
Here is something a little different.
Its just one unedited clip fro the camera. Its to illustrate how it is shooting with a camcorder compared to a cinema camera. In other words, with no worries about media space, battery, NDs, etc.
I graded at a random point and did no adjustments so it doesn't change with exposure.

 
Next we have the Metabones

Received the Metabones EF to MFT Smart Adapter today. First thing I did was to make sure the stabilization in my EF lenses worked.
I also, even though I rarely use it, tested the auto focus. And I was quite surprised.
It was pretty decent on both lenses.
Better however on the 24-105, much more quite as well.

 
your dog is too cool!

by the way, it's so sad that this camera didn't get the success that it deserves. I think that colors in log mode are excellent.
How do you find h264 in-camera compression?
 
When I rented this camera last month, I thought it was pretty great overall with lots of different features. However, I feel that JVC never stood a fair chance.

They really have to offer a ridiculous feature set to get back in the game and turn some heads because many people may not give them the proper look they deserve.

Thanks for the review. One thing I'd like to add (if it wasn't mentioned anywhere) is that the audio preamps are fantastic.

Yeah the camera is underrated, but it might pick up, my review is looking to become a positive one.
The compression is nice. The 4K looks nice and clean to my eye and I have yet to see any moire:
It can get a pretty ugly noise if you push and then grade somewhat under exposed, low contrast shadows. When that happen I just crush the shadow a bit. In daylight and lowlight is no issue. Its more of a dusk/dawn thing.

The HD 4:2:2 looks excellent.

I agree, people are weird when it comes to what "brand" that peaks their interest.
I belive if more people knew that JVC stands for "Japan Victor Company" it would be different. I mean how cool does "Panasonic" sound compare to that ;)
 
Wont have time to complete the full in depth review for a few weeks and have to return the camera to JVC.
So I bought one for myself. Here are 5 reasons why.

 
Great review, thanks for sharing.

I just picked up an LS300 as a replacement and/or upgrade over our AF100. Interesting camera to say the least, with lots to like.

JVC Announced a 120FPS firmware update (free) for it too: http://pro.jvc.com/pro/pr/2016/releases/gyls300_slomo.html

I also put up a more lyrical set of first impressions (not a review) by doing the unthinkable with an 8-bit compressed-codec camera: https://medium.com/@krispii_p/jvc-g...-elephant-in-the-room-79ea5f1e5f61#.ryqdteqcv
 
Yup, the FPN in the low contrast mids can be scary at first. I just have to remind myself that its an 8-bit camera and even though I would have loved to use all the detail I see in J-log, its 12 stops and that's what I will get. I can see +13, but it will look like garbage when graded. So I keep the mids in the mids and the image comes out nice.
 
Increasingly happy thus far.

I took it outside today - it was another "terrible" test for this thing. Low contrast, grey skies.

J-Log 50mbit/422 - stands up surprising well to multiple passes. I did some terribly quick tests and lunchtime and came away very pleased. Please don't judge the choices, I was simply trying to break the codec.

Nice to see a fellow user torture the thing a little.
I did some tests today of the cine gamma to see what I can make of it in a low contrast and pretty dim light.
Will get back with results.
 
I was packing up the loaner thats shipping back to JVC when I thought I would do one last thing. Some experimenting with the Cine Gamma.
The J-Log is really great. It has a nice roll of and I love using it specially on bright days with a high dynamic range.


But in dim light, specially low contrast, it doesn’t withstand grading very well.
The noise can turn very ugly and FPN if not careful. So far my fix for it has been to expose down. If its dark, let it be dark. This isn’t a night for day camera.


Today I tested something else. Anybody that uses Sony and S-Log knows that in many low contrast situations its better to switch to "Cine Gamma”. Specially to preserve skin tones. And it seems JVC is no different.


I shot some clips of myself in a mirror. There is no direct light hitting me, its pretty dim.
If you look at my sweater on the arm you can see how the J-Log has a nicer roll of, while the Cine Gamma has a harsher clip. But you can probably also see how much nicer the skin gets, specially on the shadow side. There where less banding on the wall as well.
Also the J-Log is almost breaking after the Grade and a WB correction.
The Cine Gamma had the correct WB but I still feel there is more leverage in a situation like this.

J-Log Ungrdaed


J-Log Light Grade and WB fix


Cine Gamma Ungraded


Cine Gamma Light Grade


Cine Gamma Graded to my liking





So now I can’t wait until my own LS300 gets here, because I need to give the Gamma settings and Picture Profiles a thorough run through.
There is for example a WDR mode I need to fiddle with.

Cine Gamma WDR Light Grade


Cine Gamma WDR Ungraded
 
BTW: Guess What!?
If you recall back in the days of the BMPCCs youth we tested all kinds of s16 lenses, including these cheap CCD lenses.


Well I thought what that heck, could be fun again. I remember liking the 35mm best.



First surprise was that they have updated the build quality, now its actually not to bad.
Second surprise came when I tested the coverage to see how much I needed to remap in camera....... nothing.. its 100%.
​​​​​​​I at least 70% sure it didn't use to cover the Nex APS-C. Or at least I didn't know about it until now.


Either way, a cheap backup or a fun option for some artsy stuff.
Here are some 4K frames.
(All examples are cinema gamma, a stop or two lower DR but I still tend to use it a lot)


Ungraded


Graded






Also here is a frame from the Olympus 17mm in f1.8. Some distortion but I could easily scan way larger than m4/3 if I couldn't liv with it.
