The SJCam SJ6 Legend is one of the newest cameras released by SJCam. It is the first SJCam with a 2-inch touch screen – a novelty which few manufacturers began to implement in their sports cameras. The camera also has its own external microphone sold separately. The camera uses a Novatek 96660 chipset and for the second time for SJCam a Panasonic sensor (MN34120PA, 16MP).  Some of you might remember that Panasonic sensor was used in SJ5000+ as well.

The SJ6 slogan says:

“The legend begins today with unrivaled features & performance ”

Well SJCam, let’s see your new product.

Unboxing

Accessories

As usual, SJCam fills the box with a lot of accessories.  Like many other SJCam products, here we find:

• Camera
• Waterproof case
• Plastic frame
• Rotating curved mount
• Rotating flat mount
• 1x curved mount
• 1x flat mount
• 1x handlebar mount
• 3x screw mount
• 1x wire
• Wiper
• 2x stickers
• Manual

As always SJCam makes good quality accessories. I never say anything bad about them but this time I have to mention the length of the USB cable. It’s more or less 25cm long and it doesn’t let you properly charge the camera or charge while recording. Personally I use the camera on my car and with this cable I can’t charge it while driving.  It could make it difficult to connect with your PC too because the camera is forced to stay literally hanging between the USB port and the floor.

Design and build quality

The design of the SJ6 Legend is just awesome, probably one of the best cameras I’ve ever had. It’s beautiful to the eyes and lovely to the touch. The camera body is completely rubberized to improve grip. On the front we find the lens next to the front screen and the three front LED’s. The feeling of the buttons is perfect, with a good “click” followed by a “beep” sound.  With the waterproof case the feeling remains extremely good. This is my first touch screen camera and to be honest I didn’t expected such a high quality screen.  I was expecting something inaccurate, with no quality and hard to use. Guess what I found?

I found a phone screen. I’m not kidding, this screen is just like your phone screen: reactive, sharp, fast, beautiful to see and perfectly bright. It was an unexpected surprise to me and probably for all the other skeptical people like me. It also works perfectly at low temperatures. I tried it at -2C° without problems. Also with the waterproof case there are no problems with touch precision.

Furthermore I want to congratulate SJCam for adding lots of lights everywhere.  The SJ6 Legend’s LED’s are visible from every angle.  They also added a little but very useful thing, the integrated screw mount on the bottom of the camera body, in Yi, YI 4K and Sony FDR-X1000V style. This mount allows you to mount a camera onto a tripod or anything with 1/4″ screw.

What can I say, the body of the SJ6 Legend is good looking and has good quality.

Buttons, lights and ports

• 1. Shutter button
• 2. LED
• 3. Power button/ Switch mode button
• 4. LED
• 5. Multiple function LED’s (Power on/WiFi/recording)
• 6. Lens
• 7. Menu button
• 8. Front screen

• 9. Mic
• 10. HDMI port
• 11. SDcard slot
• 12. USB port

• 13. Recording LED
• 14. Charge LED
• 15. Back Touch Screen

Let me say a couple of words about the USB port on the SJ6 Legend.  It’s not the usual micro USB like nearly all other cameras but rather it’s a mini type B USB.  You can find it on some of your hard disk drives but it’s very unusual use it on action cameras.  Even so, the SJ6 isn’t the only one that has this USB type. Gitup Git 1, Git 2 and the Dazzne P3 also use it. Probably the choice is made in order to use the same port for the external microphone and the charger.  It’s also much stronger than the “classic connector” called Micro-B but it remains quite annoying because you must use a different cable.

Menu overview

In common with all SJCam menus the SJ6 Legend’s is easy to use and very intuitive, in particular on this model because it’s possible to drag the menu up and down like a smartphone menu using the touch screen. The interface is almost the same as the Yi 2 4K.  Check it out if you want to compare them for yourself!

The menu is divided in two macro sections.  The first is the “fast” – quick acess section where you have instant access to all modes of the camera.  This consists of:

1. Video – Record a video
2. Video Lapse – Shoot a photo every second and automatically create a 30fps video
3. Slow Rec – Makes a slow motion video automatically
4. Still – Shoot a photo

SJCam has exaggerated again with the settings just as I noticed when I reviewed their M20 model.  Some of them, such as sharpness, bitrate and quality, are simply useless because they don’t change anything on the images.

Video

I appreciate when a manufacturer tells the truth about their product on the product packing. SJCAM wrote that the 4K is interpolated and that’s great! For everyone who doesn’t know,  interpolation is the action of literally inventing pixels to reach a higher resolution. However, in doing so there is a big quality loss. If you want go deeper you can find the reasons here but the SJ6 Legend can’t achieve true 4K resolution.

However, the 4K resolution isn’t the only problem because SJCam claimed “120fps” and “240fps” on 720p and VGA resolutions respectively but it’s not true.  Luckily this time all the resolutions and frame rates are good except for these two.  The first is actually 60fps with doubled frames.  The second is 80fps with tripled frames! I’ve never seen something like that before.

Please remember that this camera uses a Panasonic sensor so it’s normal to find quite high quality videos: great colors, very good images and quite good sharpness. But if you use the SJ6 Legend without good lighting, it could be a problem.

Usually an action camera is made to record videos in extreme situations – on a bike, during a run, on the snow, under water.  They’re made to capture incredible shots where and when other cameras simply can’t, but with this camera it can be frustrating because with some particular motions scenes are not as detailed as expected.  On the other hand it can sometimes be very satisfying.

I found another strange problem. Sometimes, in a totally random situation, the camera makes a completely violet frame, just one.  It’s most frequent in dark conditions. There was a similar problem with the Sjcam M10+. Probably it’s a firmware problem but they didn’t fix it with the latest version.

Here’s an example.  You can see it at 8 seconds and again in slow motion at 16 seconds:

And this is a frame capture:

The camera makes good videos in daylight but during the night things change. Strangely it can capture light very well even from dim sources but it doesn’t capture the details. During the night it seems constantly blurred.  It also halves the frame rate when there is insufficient light. This is common for action cameras but it could be frustrating to set the camera at 60fps and have it record at 30fps just because the camera wants to.

Update : The violet frame rate issue has been fixed in one of the firmware upgrades.

I noticed another strange effect when the camera is facing into the sun. It creates a “glass effect” to compensate for the huge amount of light. This is how it looks in bright light just before the sun hits the lens directly:

And this is how it looks with the sun shining directly on the lens.

In this situation other cameras have different methods to avoid this effect such as decreasing the exposure. In this case I’m not sure if it’s a firmware problem or a hardware problem caused by the lens.

Apart from these problems there is a new feature I’ve never seen in any other Chinese action camera. I’m talking about the 1080p Super. What is it? It’s a copy of the “Super wide angle” by GoPro, and personally I like it! It’s an extension of the higher and lower edges at the expense of distortion. The difference is clear:

It’s very noticeable with slow shootings but in action it doesn’t seems that bad because the angle is taller so the viewing is better

Photo

This is an action camera and usually they’re not made for or used to shoot photos, but if it can take good photos then there’s nothing wrong with that! But don’t worry, with the SJ6 Legend there’s no risk of taking good photos because the quality is very poor. The resolution is high, the sensor is good (Panasonic) and the colors are very beautiful but the details are lost.

At night it’s worse:

Once at home I noticed the sky in the photo was much brighter than the actual sky. It was sunset and it wasn’t this bright. In fact cars already had their headlights turned on. The speed of the photo was 1/16s – not fast but not so slow as to be a “long exposure” photo.

Photos have another annoying problem. Sometimes if you try to shoot a 16MP photo the camera freezes and shows this message:

Sorry for the photo but it happens randomly, this time when I was in my car.

Whenever the error occurs the camera creates this file on the SDcard:

Audio

The SJ6 Legend records good quality sound with a beautiful mix of high and low frequencies without distortion. One minor criticism might be that the volume is a little bit low but nothing serious.

Battery Performance

Here are the battery test results:

• 4K 24fps – 70min 11.3Gb
• 2K 30fps – 72min 15.3Gb
• 1080p 60fps – 65min 13.6Gb
• 1080p 30fps – 113min 17.6Gb
• 1080p 30fps 4:3 – 113min 17.6Gb
• 1080p 30fps Super -113min 17.6Gb
• 720p 120fps – 105min 22.2Gb
• 720p 60fps – 76 min 10.6Gb
• 720p 30fps – 125 min 8.7Gb
• VGA 240fps  – 108 min 14.9Gb
• Recharging Time – 120 minutes

The tests were made with the screen and WiFi off. With the WiFi on the times could decrease by half.

07/04/2017 NOTE – After 7 month of daily use, the camera had a significant reduction of its battery life. Today it is exactly the 25% lower than when I first tested it. Wow the camera in 1080p 60fps can reach max 45 minutes of recording. Even though slight reductions in battery life are possible, especially with every day usage, the reduction of 25% seems like quite a lot.

WiFi and App

The WiFi and app are absolutely perfect. It’s the same app as every other SJCam camera and the WiFi with the SJ6 Legend it works. By “works” I mean it does its job without problems and it’s fast (it can reach 2MB download).  SJCam probably has one of the best pairings of WiFi and app you can find among Chinese action cameras.

Support

I had the opportunity to use SJCam support and to my surprise it’s just how support should be. They answered my questions within 24 hours and they’re very friendly and professional. I exchanged a few e-mails and they replied to me EVERY TIME. They also made few helpful suggestions. This is what I want from company: Help the customers and do so with a professional attitude. In particular I want to thank Miguel for his incredible patience with me!

Summary

The SJCam has a great advertising campaign so it must be a great camera, right? I was expecting something on the level of a GoPro or YI 4K but it instead it was just another camera with some good features but without the incredible part. It has too many little issues like the violet frame, the freezing photos and quite bad performance in dark conditions and together they makes a big problem. I hazard to say that her little sister, the M20, is on the same level. Surely we’ll see a comparison between them on Pevly!

Pros

Cons

Firmware Upgrade V1.4.3

The entire review was based on the first firmware, version V1.0, because the camera was just released. This month SJCam released a huge firmware upgrade on this the SJ6 Legend. They released version V1.4.3. You can see all the fixes on the following link.

In my opinion the biggest fixes are:

• Added new frame rates, 1080p 50fps and  1080p 25fps (they are real).
• Fixed the crash problem with photos. It wasn’t actually a crash but a hot pixel fix, a sort of mini tune-up for the camera. It used to start after holding down the shutter button for 2 seconds. Now the time has been increased the from 2 to 10 seconds so it‘s harder to accidentally start the hot pixel fix.
• Fixed the Violet flash during the video recording.
• Improved the light in night mode and in general with low light conditions. Now the images are brighter

After these numerous changes, contrary to what they say about the image quality optimizations, I didn’t find any improvement comparing old and new photos.  Rather they decreased the video quality! Here you can find an example between two frames of the same subject with the different firmware versions:

It’s clear that is was sharper originally. Obviously I made this comparison with the same options.

We’ll see if there will be further improvements in future!

Where to buy SJCAM SJ6 Legend

Today we’re here to review one more tiny action camera – SJCAM M20, advertised as the smallest camera SJCAM has ever made. The small-sized camera I reviewed was the AEE MD10 and this one is no bigger.

Personally I love the SJCam brand.  My first action camera was the SJ4000 and with this latest camera SJCAM has made a great product. With the M20 model they used a 16MP sensor by Sony and usually when there’s a Sony it means there’s good quality. The thing about this sensor is that it’s tinier than others, it’s back-illuminated and has lower power consumption. So as George Clooney says in a famous TV ad, “What else?”.

I think it’s time to show you the camera so let’s do it!

Specifications

The M20 has all the specs to be a great camera, probably one the best and cheapest on the market, so let’s see product specification in our traditional table.

Unboxing

If you’re curious about what’s included in the box, here you go: the unboxing video!

Accessories

Like all other SJCam’s it’s full of accessories – look at them!

• M20 SJCam
• Waterproof case
• Base mount
• 4x Screws
• 1x curved M3 mount
• 1x flat M3 mount
• 1x floating curved M3 mount
• 1x floating flat M3 mount
• USB cable
• 1x Cloth
• 2x SJCam stickers
• 1x Manual

An optional remote control is available but wasn’t included with the camera I tested.

The rotating mounts are interesting accessories.  They allow 360° movement while installed on the M3 mounts.

Design and Build quality

The M20 camera has an easy and practical design because it has the essential buttons for navigating without problems. This is a classic SJCAM feature, one of the many reasons I like their cameras. These cameras must be easy to understand with an immediate visible impact and the M20 has all of this. By the way if you can see a comparison between all SJCAM models in this article.

The camera is very light to the touch but solid – there are no “dancing” buttons or slack ports. The front of the camera is made with a rubber surface to ensure a perfect grip and the rest of the camera is made by the classic striated plastic.

The buttons are good too.  The two on top are concave to provide a better grip for your fingers and on the side are the usual SJ arrows to navigate the menu.  The WiFi button is also on the side. As always the accessories are good quality for a cheap camera.

Buttons, Lights and Ports

Here’s a description of the buttons, lights and ports:

• 1 – Recharging LED
• 2 – 3^rd Recording LED
• 3 – Lens
• 4 – Recording button
• 5 – 2^nd Recording LED

3. HDR (On/Off)
4. Mode (Photo/Video)
5. Resolution/Frame rate
6. Audio (On/Off)
7. Battery Status
8. Gyro (On/Off)
9. Memory Left
10. Time

Unlike a lot of similar cameras the M20 has good software.  It’s very stable and has no problems. The menu is perfectly intuitive and easy to use thanks to the nearby buttons. The display is completely visible in any condition and even in full light it allows you to read the menus and OSD without problems.

Menu Overview

As I said before, this camera has great software, very intuitive and very stable. The menu has two modes, Video and Photo, changeable with just a click on the power button, and by a full menu with other modes and options:

1. Video/Photo Mode -> These are the main modes switchable by pressing the power button
2. Playback -> Here you preview photos and videos you captured
3. Video Lapse -> This mode is to make a video in time lapse
4. Slow Recording -> This mode is to make slow motion directly with the camera (-x2/-x4/-x8)
5. Photo Lapse ->This mode is to make a photo lapse (3s/5s/10s/20s)
6. Burst Mode -> This mode is to make 3/5/10 photos consecutively
7. Underwater Mode -> In the mode the camera changes the color palette to optimize underwater colors
8. FPV -> You can choose between LCD/FPV/LCD+FPV
9. Motion Detection -> In this mode the camera starts recording if it detects movement in front of it
10. Car Mode -> In this mode the camera turns on automatically when the car starts and turns off when you turn off the car (obviously the camera must be attached to the car charger)
11. Remote Control (On/Off/Pairing)
12. Options

As you can see the M20, like all other SJCam cameras, has too many settings and some of them are completely useless. For Bit rate, quality and sharpness there’s no difference between the higher and lower settings so… they are simply useless.

Video

The M20 has 5 different resolutions: 4K@24FPS,  2K@30FPS,  1080P@30/60FPS,  720P@120/60/30FPS and VGA@240FPS. Let me say right now now that some of these frame rates are false. First of all I noticed that the box says “2K cam” and not 4K because actually it’s not a real 4K.  In fact on the side of the box the SJCam says “4K interpolated”.  At this point I thought all the other resolutions and frame rates were right because if they were honest with the 4K then there’s no need to lie about the others.  Well, I was wrong.

The real resolutions and frame rates are:

This is a practical example of false 720P@120FPS and a real one:

Same thing for the false VGA@240FPS and a real one:

This is absolutely ridiculous because the M20 has a processor that can make the claimed frame rates so I don’t know why SJCam decided to tell this HUGE lie.

Okay, apart from this annoying thing, let’s talk about how this camera really records videos.

First of all I want you to remember that this camera has a Sony sensor.  In fact the video results are very, very good with incredibly true colors. This camera works great in every condition, even at night! I found just a little “problem”; it’s not a real problem but it could be annoying for some. In this video focus on the sky:

As you can see the sky literally pulses. This is because the camera focuses the image in the middle of the field of view (FOV).  It works to make the center as good as it can so the “pulse” is nothing more than a light variation to always make the center perfect. Personally I don’t care for this, at least for my needs, and I understand if some people could be annoyed with it.

Another great thing about this camera is the Gyro sensor. It makes a huge difference in stabilization at the cost of a little bit of field of view. To understand how much “space” it takes, this is a little comparison:

In this dashcam test notice how the gyro follows the movement of the car while it turns:

It makes very stable images without any optical stabilizers:

But the gyro also has a limit.  In fact when there’s too much shaking it’s better to disable the function in order to avoid the blurring effect:

To my own huge surprise this camera allows you to see in dark conditions thanks to the back-illuminated sensor.

However there’s still a problem with the amount of noise in the images.  It’s very annoying because of the lack of details.

I also discovered that in night conditions the frame rate is lower than in full light condition.  That means that when the camera is set to 1080P 60fps it’s actually 30fps.

This is a good action camera, maybe one of the best I’ve ever tried, so the problem with the frame rates is a shame.  I hope they fix it in a future firmware upgrade.

Photo

This camera can shoot incredibly good photos, probably the best I’ve ever seen after the Eken H8R. It shoots 16Mp photos with a great resolution.

The only problem is the common problem of “painting”: the far details seems like they’re made with a paint brush. This problem is minor because these kinds of cameras are not made to shoot photos like a real camera.

By the way, the general impact is great, even in back-light as you can see.

I also want to show you the difference between the FOV variation:

The only real difference between “Tiny” and “Medium” is the quality. Tiny has very bad quality and medium has normal quality.

As you can see above, whether photos or videos, the colors look great but there’s a lot of noise when shooting at night.

Audio

I’ll be honest with you, all the videos above were made with the audio settings on default, i.e., on a scale from 1 to 10 it was set to 7. Luckily I found it just in time to record the audio test and show the differences between volume 1 and volume 10 at various car stereo levels.

The volume set on “1” is near to mute – you literally must scream into the mic to hear something.  With the volume at “10” it’s sometimes too sensitive, enough to hear scratching yourself while driving!  I advise you to set this parameter to 8 or 9, neither more nor less, to have a good audio level.

As you can hear the audio is good.  It’s not made to record an EP but it’s versatile enough to use it in every situation from a concert to school to a talk with your friends.

Battery Performance

The results of the battery test are:

• 4K, 24FPS – 101 minutes, 16.4Gb
• 2K, 30FPS – 100 minutes, 21.3Gb
• 1080p, 60fps – 84 minutes, 17.9Gb
• 1080p, 30FPS – 120 minutes, 17.4Gb
• 720P, 120FPS – 120 minutes, 25.1Gb
• 720P, 60FPS – 120 minutes, 15.7Gb
• 720P, 20FPS – 123 minutes, 8.62Gb
• VGA, 240FPA – 143 minutes, 19.8Gb

The recharging time is 105 minutes

That’s good performance for a 900mAh battery. I noticed that the last quarter of the battery takes more time to finish so if you’re at that last quarter you can still shoot some more videos.

WiFi and App

The WiFi and app are other two strong points because I never found any problems with them. The WiFi has a perfectly stable connection and the app is clear and easy to use.

As part the options for the video/photo modes and video/photo time lapse we can change a lot of settings:

• Resolution
• Cyclic record
• WDR
• Audio
• Date stamp
• Rotate
• Gyro
• Video time lapse settings
• Image size
• White Balance
• Exposure
• Capture mode
• Frequency
• Default settings
• Format
• Auto power off
• WiFi name
• WiFi password

As you can see there are more settings than with other cameras and this is good because it allows you to change them from a distance.

In Playback settings you can see the files on both the camera and phone.

On this menu you can choose to download files from the camera to the phone or to delete files.  This works particularly well because the transfer rate easily reaches 2Mb/s.

Summary

With the M20 I can say that SJCAM has made another good camera.  It’s cheap, easy to use, has a good battery and stable software. The only notable cons are the issue with the FPS (I hope they will correct it with the next firmware upgrade) and the huge amount of noise in night images. I think that for $119 you can’t ask for anything more.
