DJI OSMO 4K camera comparison test with the Inspire X3 camera

DJI OSMO 4K camera comparison test with the Inspire X3 camera

Ever since the first prototype was going around the DJI booth at NAB this year, teases of a handheld version of the Inspire 1 gimbal/camera have been making many owners anxious to finally have the option of taking their X3 camera off their drone and continuing to shoot on the ground with the same quality stabilized camera footage for more seamless productions. Well, now they finally can (kind of).

 

OSMO-X3-compareBased off the same professional 4K camera base that DJI developed for their Inspire 1 quadcopter, the new OSMO handheld stabilizer camera is a perfect companion for the aerial photos and videos you’re taking from the sky. Or, you may just have a need for a solid and easy to pack gimbaled 4K production camera that isn’t just a GoPro on a stick – nor a hefty MoVi with a big DSLR attached to drag around. And for about $650. complete, the OSMO might just fill that need and small enough to toss in your gear bag.

OSMO-w-SmartphoneThe folks at Multicopter Warehouse sent me one of the first production units in to the US to test and review, so I’ll share some of my examples and impressions of it so far. I do some side-by-side comparisons with both the OSMO and the I1 X3 camera to share with you and let you decide if you need the full OSMO camera today or if you can wait for the handle-only kit to come out and use the camera you already own on your Inspire 1.

DJI OSMO HANDHELD GIMBAL AND CAMERA

I’ve tested several different gimbaled handheld stabilizers over the past couple of years – some for smartphone and some for GoPros, and all have done a lot of similar things: they stabilize the camera so you can move freely and get smoother video from a handheld position. Most have worked fairly well, so I’m familiar with them and how they should work. The DJI OSMO is different in many ways, however – primarily in that you control the camera operations from your smartphone device which doubles as your wireless viewfinder screen.

OSMO-profilesThe OSMO was originally based on the camera & gimbal design on the DJI Inspire 1 quadcopter’s X3 camera and an early prototype was teased around at NAB this year – a handle that held the X3 in an upright position instead of it’s usual underslung orientation.

While many UAV photographers and videographers have been waiting for the OSMO to arrive (most impatiently on the social media boards), many were disappointed that the only configuration you can currently get the handle was to buy the complete unit with the OSMO camera included. After doing my initial tests when I first got it, I discovered that the Inspire 1 X3 camera does not exactly work well with the handle and the software did not connect your smartphone to it correctly either. However, note that DJI has been doing a lot of firmware updates and beta testing new builds that will eventually incorporate use of the I1 X3 gimbal/camera. I will follow-up with finalized results in a later release, but take heart that they are indeed working on this!

The gimbal on the OSMO also locks in all three axis, so it’s not flopping around in the case or if you lay it down on a table when not in use. The OSMO fits neatly inside it’s custom storage case (included) when fully collapsed. And while the case is kind of cute and looks like a little violin case (or a handgun case, perhaps) there’s no additional room for the battery charger, extra battery or even filters inside the case so you’ll need to toss those all in your gear bag. Plus being an asymmetrical shape, it doesn’t pack very easily.OSMO Montage 1

 

The feel and design of the OSMO is really quite nice. It has a professional feel and heft to it without feeling too heavy, not cheap like a toy. The smartphone bracket is pure genius in design and fabrication alone, and really holds phones up to the iPhone 6s Plus and has soft rubber padding to secure your phone without scratching the case. The phone holder rotates in position so whatever angle you’re holding OSMO, you can see your viewfinder screen and camera menu/controls. It also detaches with a 1/4-20 mount that you can then use other mounts and accessories like an extension arm, telescoping pole, bike mount or suction cup vehicle mount (accessories available soon). I attached the OSMO to a tripod and it worked great. More on that later…

OSMO Camera Features

The camera settings and viewfinder are all presented on the smartphone screen and connected through WiFi, so there’s no cables, unlike other camera based DJI products like the Phantom 3 Professional and Inspire 1, where the tablet or smartphone are connected directly to the radio controller via cable. I first thought it was strange to not have a cable connection of some kind as it’s a bit cumbersome to have to reconnect the WiFi every time you turn the OSMO off and on again and you’re in range of a known WiFi hotspot with your smartphone.Announcement-OSMO-NA-8

 

The smartphone app is the same used by the latest DJI quadcopters, called DJI GO and will automatically recognize the OSMO once you’re connected by WiFi and will display the camera’s viewfinder image as soon as it’s selected from the menu.

All of your separate menu settings are clearly marked and those already familiar with DJI’s app will quickly recognize most of them. You have separate controls for photos and video, plus a full range of exposure controls and white balance settings. There’s also advanced settings for gimbal controls and other features.

The fan-cooled gimbal-camera is utilizes a Sony 1/2.3-inch 12-megapixel sensor that can record videos of up to 4K resolution — 4,096 x 2,160 at 24fps or 3,840 x 2,160 at 30fps/24fps, to be exact — with a maximum video bitrate of 60 Mbps. If you want a smoother video, you can go up to 60fps at either 1080p or 720p, or even do slow motion with 120fps at 1080p. It features a 20mm f/2.8 lens with a 94-degree FOV. You can shoot 12MP still images as well in both JPG + RAW (DNG) that can be edited in Adobe Lightroom and Photoshop (ACR). There’s also an automated 360º pano mode, which I’ll share more about later.

The microSD card slot is on the side of the camera pod on the gimbal and comes with an included Lexar 16GB UHS Speed Class 3 card.

There is a built in condenser mic but it’s practically useless at the moment, but word is there may be some firmware updates to resolve some issues in the future, but we’ll get into more about that later in this review.

The handle controls allow you to reposition or lock the gimbal’s yaw motion with a finger trigger and a pan/tilt thumbstick. You can also start/stop recording video and take single frame images with two other thumb controls. This frees up your other hand to change settings on your smartphone screen, operate other gear or just hang on tight while you’re getting a ride down the road grabbing awesome action shots!

There are three different yaw control modes with the trigger switch on the front of the OSMO handle: Single click + hold, and it locks the gimbal in the direction the camera is currently facing, no matter how you twist or reposition the handle. A double-click will re-center the camera out ahead of you. And a triple-click will swing the camera gimbal around into selfie mode for bloggers and the man on the street reporting.

But unlike all other handheld gimbal stabilizers I’ve used, you can actually “touch” the camera head! In fact, you can manually grab the camera and move it with your hand to a position you want and it will just stay there. A simple double-click with the trigger switch and it snaps right back to the center neutral position.

Testing the OSMO right out of the box

Touch ExposureNote that all of my examples shared here are in default settings and full auto mode. I did this on purpose to give you a sense of what the cameras can do right out of the box without being “pushed”.

You can touch anywhere on the smartphone screen to set the exposure spot meter until you get the balance you prefer. The OSMO has a surprisingly wide dynamic range for such a small sensor camera. By default there are Zebras for exposure but I haven’t yet dug into the menus settings to see if their values can be changed or not.

You can also tap/hold on the screen to slide your finger to smoothly reposition the gimbal head in any direction – pan/tilt. This is really useful when you have the OSMO mounted on a tripod or a rigid mount or car. Since the smartphone is connected by WiFi, you can easily control it without being attached to the handle – as long as you are in WiFi signal range.Tripod-mount

 

Here’s a video I compiled with some basic test scenarios over a few days. You can see that the 3 axis are covered pretty well, but the yaw can be a bit jerky at times with the stock settings. I’ll be testing some advanced gimbal controls to see if that can be tuned out later. Other than that I’m pretty pleased with the stabilization it gives for a 3-axis gimbal. If it also had one more axis like a Steadicam gives (up/down) then the walking motion would be almost entirely eliminated.

Video examples are in full 4K so be sure to click-through to YouTube and view in 4K HD. Note that all the clips are straight from the OSMO camera with no post-processing or color grading of any kind (Camera comparisons are later in this article):


First tests in the field (literally) and in ambient light conditions – look for actual comparisons below.


Testing indoors with ambient light at a manufacturing plant (notice the tilting horizon/level issues in some shots, as well as a “float” sensation while walking with the OSMO).

Still image quality and clarity

OSMO-DNG-100-detail-1024x642I shot some tests in the studio under low/ambient daylight conditions to see how the noise levels would be and how the focus and auto exposure functions responded. Click on the image on the right to expand it to see the details of the shot at 100%.

Shooting Panoramas with the OSMO

One of the still image options on the OSMO is the 360º pano mode. When this is selected and you click the photo button on the handle, the camera will automatically rotate a full 360º and fire off a single image every 45º to give you 8 images. You can stitch these images together on your desktop workstation with Adobe Lightroom or Photoshop or other programs like Kolor Autopno Giga.

Pano-File-StructureOne thing I noticed when I opened the media folders on the microSD card, was there is a separate folder for the Panorama files (with a separate sub-folder for each group of images in a pano) so organization of the panos is much easier. However there is also an HTML file added to the Media directory that merely opens up the subfolders if you try to launch it, so I’m not sure what its purpose is.

When you’re taking the panos with the OSMO, the app on the your smartphone will process a stitched preview for you and save it to your Photo library. It’s only a preview file though and is pretty dreadful as a final result as you might expect on an iPhone pano, as you can see below.Ranch-360-Panos-1200

 

Pano-error-bracket

Also, depending on the tilt of the gimbal and how you’re holding the OSMO handle when you take the photos, you will find that your hand, parts of the smartphone/bracket or your fat head get in the way.

I’m thinking you may not want a complete 360º pano in the end but possibly only 240º or less, so perhaps you can position your body away from the main area you’re trying to capture and crop it out afterward, like this example looking out over the valley and reservoir below.

COMPARISONS with OSMO vs I1 X3 Camera:

At the time of this testing series, I did my comparisons with the OSMO by itself and mimicking the same movements with the Inspire 1 turned on and connected to the remote controller and iPad mini to set my camera, and hand-held the Inspire 1 to use as a gimbal device. This is quite awkward to do for very long, as you can’t really see what you’re capturing (unless you have a second person with the RC) and the weight/size of the Inspire 1 gives your arms fatigue after some time. However, after spending some time with both devices, it’s easy to see that the lightness and lack of mass in a single handheld stabilizer tends to have more “float” as it’s very difficult to keep a single hand perfectly steady when waking in any direction.

I set uptown different scenarios for the comparison testing in various conditions. One was with ambient room light with a skylight in our photo studio with a mannequin, a laptop with a pattern and a camera focus chart printed and attached to the back wall. This gave me several points of auto-exposure resetting and can gauge how well each camera responds to these extreme lighting conditions one may encounter in an actual production environment – not a perfectly-lit studio that most users don’t have access to.

The second scene was outdoors on a bright day – again with full auto on both cameras, but with an ND16 PolarPro filter to cut glare and decrease shutter speed. I made sure to incorporate close and distant objects as well as bright sky and movements were made similarly.

OSMO-DNG-dataThe settings on the OSMO camera at f/2.8 1/15s 3.6mm produced an auto setting of ISO 152

X3-DNG-dataThe settings on the Inspire 1 X3 camera at f/2.8 1/15s 3.6mm produced an auto setting of ISO 263

This video shows the comparisons one after the other and side-by-side. Be sure to click-through to YouTube to watch it in full 4K (though H.264 compression has been applied for YouTube streaming):

Although DJI has claimed the OSMO camera is supposed to be redesigned with clearer close-range focus than the I1 X3 camera, I’ll let you be the judge to determine if the difference is that extreme to warrant getting both, or just wait until the Handle Only kit is available and just use your I1 X3 gimbal/camera.

I believe most people will probably get the full OSMO for ease of use on location so they can quickly go from sky to ground without messing about with attaching the I1 X3 cam, but the option will be available in early 2016.

Third-party audio options

The built in condenser mic is useless as tested. Besides the noise of the cooling fan and buzz of the gimbal motors, the low gain on the mic render it totally unusable for anything – save for possibly a loud (LOUD) clap board to sync purposes. You must use a powered boom or condenser mic (or wireless lav, etc.) through a powered mixer or source to boost the audio level going into the OSMO (via a mini-stereo jack on the front of the handle). The problem is, how do you mount a mic to the handle if you’re using it handheld and need the smartphone holder installed?

AudioClipTo solve this issue, Josh Gilson and Kerry Garrison over at Multicopter Warehouse came up with a device for getting an external condenser (powered) mic to work with the OSMO on their Cold Show Accessory Mount ($9.99).

This also places the mic far enough away from the gimbal to not only clear the camera pod movement but also separate it from the noisy fan and motors.

OSMO & I1 X3 Filters

PolarPro-Filters-1200The nice thing about the OSMO camera’s design is that it utilizes existing filters made for the DJI Inspire 1 camera. This set of Polar Pro filters work nicely to cut glare and offer a richer, less burned-out look in daylight shots.

This 3-pack includes a circular polarizer, and ND2 and ND3 filter, complete with protective carry pouches. The OSMO comes with a standard UV filter that unscrews off the front and these screw on in place. However, the Polar Pros aren’t designed to be stacked so only one can be mounted at a time.

Overview

This long-awaited prosumer-grade camera and stabilized gimbal is a welcomed addition for the generalist videographer and professional that needs a quick run and gun stabilized camera. I’ve known DJI for several years now and I’ve watched them enhance products shortly after they go to market with software updated and firmware upgrades quite regularly. I’ve been updating the firmware at each release and there are still some lingering issues, including a horizon-tilt drift during use requiring constant recalibration and resetting the unit, but I’m sure that will get resolved soon as well.

The battery life is quite dismal, however; if you’re conservative and put it in sleep mode after ever shot you might get an hour or two out of a single charge, but leaving it running you’ll be lucky to get 30 minutes. It does charge quickly but my advice it to stock up on extra batteries!

The built-in audio/mic just sucks and is unusable. Only an pre-amped external mic option will make the OSMO a fully-functional handheld recorder – if that’s what you’re really in the market for. Chances are, most videographers are going to be using the OSMO for B-roll and not have a need for audio, but the capabilities of this handheld device are just starting to surface, and I think we’ll see a lot of creative uses for it in the near future.

Price as tested: $649.00
