Mobile phones are an important equipment for many outdoor videos live streaming and short video shooting for vloggers. Shooting videos with mobile phones and cameras in a moving state will cause screen jitter and instability, and it is difficult for mobile phones to obtain smooth videos. The best stabilizers can help you. How to choose the best camera stabilizers 2020?

Part 1: What handheld smartphone gimbal can do?

I believe that many outdoor travel enthusiasts shoot sports video vlogs. We hope that the video pictures look smooth and have no jitter. The widespread popularity of smart phones has also opened the era of real-time streaming media.

If you want to shoot high-quality videos, the image stability is very important. In addition to simple scene shooting, we can use our hands to keep the lens as stable as possible. Live streaming, video vlog, or time-lapse photography,slow motion, panoramic photography, night scenes, object tracking, overlapping images, push-pull zoom (Hitchcock), etc., are not a single mobile phone that can be played well, which requires the best video stabilizer for smartphone.

Part 2:How to choose the camera stabilizer for Phone?

1. Stability

In recent years, with the replacement of mobile phone stabilizers of various brands, the stability function of the stabilizers on the market is sufficient to meet the daily shooting requirements. The stability is good or poor, from the same price point, the difference is not so obvious. Of course,the well-known brands Zhiyun and DJI may have better user experience in many aspects.

2. Lightweight and Portable

The lighter the body of the mobile phone stabilizer for video recording,the more conducive to long-term shooting. It also has a foldable and retractable storage, which can be directly placed in your pocket or backpack and carried with you. This is the most practical feature for outdoor enthusiasts.

3. Application

The mobile phone stabilizer can withstand multiple mobile phones,according to the weight of the existing mobile phone or the applicable equipment, refer this parameter to select the appropriate stabilizer.

4. Function

No need for levelling function, face recognition tracking shooting,gesture control, etc., all increase the attractiveness of their products to users. In addition to the smart camera stabilization function, the camera stabilizer also has a three-level fill light, Bluetooth camera controller, etc.It can be described as a multi-purpose one, which can meet the shooting needs of most scenes. You can even use it as a selfie stick/tripod with anti-shake function.

5. Simple to Use

The 3-axis stabilizer is more professional and the operation is more complicated. For novices or sport video shooting who are only used for daily steady shooting, a handheld cell phone stabilizer is more suitable. After the mobile phone is installed on the handheld stabilizer, turn on the device to do stable shooting. The operation is very simple.

Part 3: The Best Gimbal Stabilizer for Your iPhone Camera Gopro 2020

1. DJI –Reliability and ease of use

DJI UAVs are well known and are in a leading position in the international market. Because gimbals and drones have many similar characteristics in technology, with the accumulation of technology in the field of drones, DJI has also developed a series of mobile phone gimbals(stabilizers). Currently, Osmo mobile has been launched one generation, second generation, third generation.

In terms of product hardware, DJI products are mature and stable. After the market experience and optimization exploration of the first two generations of products, it has now developed a portable, foldable, and more affordable third-generation mobile phone stabilizer. In terms of product application DJI functions and user experience are also the best compared to other brands. DJI Osmo Mobile 3 is known for its reliability and ease of use.

2. Zhiyun -Strong Function

Zhiyun is a fast-rising company that has occupied many markets for gimbal stabilizers in just a few years, which has largely led to the technological progress and popularization of stabilizers. Zhiyun is very strict in product control, and the stabilizing effect is outstanding among products of the same level. It can respond quickly and switch quickly.

Smooth Q2 is Zhiyun mobile phone stabilizer, and it is the smallest and most portable stabilizer. Although the body is small, the battery has the longest battery life, and the three axes are free. It is a rare mobile phone gimbal with unlimited heading axis. The best mobile phone stabilizer at the same price.

3. 3-Axis Handheld Gimbal Stabilizer

The difference between 3-axis gimbal stabilizer for smartphone and other gimbal stabilizer is that it is specially designed for travel.

The gimbal has a base that can accommodate compact cameras, sports cameras and smart phones, which can provide you with beautiful and smooth shots and leave lasting memories for your journey.

The compact design makes this gimbal an easy addition to your camera bag without the need for heavy equipment. Whether you are shooting with GoPro, iPhone, compact camera or even mirrorless camera.

Different shots have different requirements for stabilizers, so on the basis of determining the budget, choose the most suitable smartphone gimbal in this price range.

In the era of sharing life videos, our way of expression is different from the past era of paper media, text, and pictures. Regardless of daily life,parties, travel, outdoor sports, and creation, they will gradually become like to using vlog to share. I believe that a camera stabilizer gimbal is worth.

The focus is not working. You can move it buy it doesn't adjust the focus.The focus is not working. What should you do if binoculars not working? Hope that the methods in this article can help you how to repair binoculars at home?

[attachimg]15480[/attachimg]

The focus is not Working

There is a nut focusing knob on the binoculars, which can drive the screw to adjust the distance between the objective lens and the eyepiece. If the knob is turned and the eyepiece does not move, it indicates a mechanical defect on binoculars.

Howto Focus Binoculars?

1. When using the binoculars,first adjust the distance between the two lens barrels of the binoculars. The method is to hold the lens barrel of the binoculars with both hands and open and close it inwardly or outwardly until the images form a circle.

2. Close your right eye and slowly adjust the focus wheel of the binoculars until the left eye is clear.

3. Close the left eye and adjust the right eyepiece of the binoculars (if the right eyepiece cannot be rotated,there will be a ring under the eyepiece, adjust this ring) until the right eye is clear.

4. When observing targets at different distances, simply rotate the middle focusing wheel.

Howto Fix Double Image in my Binoculars?

The two lenses are not aligned,so when you look at a single object, you will see double vision instead of overlapping objects. Can this be fixed?

We see a double image because the light(images) leaving us are not parallel.

Turn the screw.

Point the binoculars at any point.

Move the screw slowly until the two images coincide.

The Binoculars Lens is Blurred Background:

Use the large screw on the top of the knob to open the focus knob.

After opening the knob, clean the binocular lens and dry it.

Grease the cotton swab and gently rub on the knob.

Tighten the screws again.

You may have to tighten the screws multiple times because they will become matte due to lack of grease.

Howto Use Binoculars Properly?

I bought a new mountaineering binocular, I was looking forward to it, but I didn’t know how to use it. I didn't adjust it so well that the images no overlapping during observation, and there were black shadows in the field of view. So, how to set up binoculars correctly?

Step 1: Rotate or fold the eye mask

No need to fold if you don't wear glasses. This is to keep the eyes and eyepieces at a proper distance. If they are attached too close or too far away, there will be dark shadows in the field of view, and a perfect field of view cannot be obtained.

Step 2: Adjust the interpupillary distance

Adjust the distance between the two lens barrels to the same distance as your eyes, so that the images can be seen to overlap. Everyone's pupil distance is different. For example, the interpupillary distance of children is relatively small, and the interpupillary distance of adults is relatively larger. Twist the distance between the lens barrels on both sides and adjust it to be the same as the pupil distance of the eye, to avoid double vision and observed without shadows.

[attachimg]15482[/attachimg]

Check the level calibration

Relax your eyes.

Look for obvious vertical lines in the structure.

Gently close your eyes once every few seconds to change the angle of view.

When switching views, look for any movement on the vertical line.

When your left eye is open, the image may move slightly to the left, and vice versa. Such slight movements are normal.

The vertical movement in the vertical line calibration adjustment is necessary multiple times.

Check the vertical calibration

Relax your eyes.

Find a clear horizontal line in the structure.

Slowly move your eyes about 4 inches away from the binoculars while continuing to observe the horizontal line.

Look for any unbalanced in the horizontal line of each view.

8 Tips for Using Binoculars:

1. Do not use binoculars to observe the sun directly, as this will cause serious damage to the eyes.

2. Avoid dropping, vibration and impact, so as to avoid the deviation of the optical axis and make the user dizzy.

3. Don't touch the lens with your hands to avoid staining the lens with grease, fingerprints, etc. that affect the image clarity.

4. Do not use binoculars while walking to avoid accidentally stepping on dangerous objects.

5. Do not put the binoculars under the scorching sun or expose it to the sun for a long time to avoid high temperature to accelerate the aging of the rubber.

6. Non-waterproof binoculars need to be kept dry for a long time, which can prevent the lens from growing mildew in a sealed bag.

7. Do not put the telescope in a place where children so as not to fall and damage it

8. Please cover the objective lens and eyepiece cover after using the telescope to prevent dust from falling on the lens.

I just got the drone a few days ago, but I have been very busy, so I can't watch how it works. But today I finally had time to take it out, but it did not take off. How to fix drone not flying?

With more information about what happened with your quadcopter and why it is not flying, we could be more helpful.

Why is My Drone not Flying?

Low Power

Make sure the flight battery is fully charged. If your drone has a battery monitoring system, the flight controller may not work when the flight group voltage is below a certain threshold.

To do this, try several steps:

Remove the battery and put it back

Put the battery in the charger,and then check whether it is charged

Check the battery status on the controller screen

Replace with new batteries

Check the battery and connector for damage

Make sure the battery meets the specifications of the original battery of the quadcopter

Check Drone Flight Axis

Check all props for damage and debris (like string) around the shaft, and arrange the propellers in the correct order. Propeller installation requires a certain turn to create the necessary airflow to actually lift the quadcopter into the air. Therefore, if these conditions are not met, your drone might start but won't take off.

Compass and IMU are not Calibrated

Have you tried calibrating the gyroscope? Turn on the drone and place it on a horizontal surface, I believe it moves down and right at the same time (may move to the left, depending on the manufacturer). Hold it and watch the LED on the bottom flash. Once it stops flashing, it should be calibrated. If the gyroscope calibration fails, it will not fly.

Please follow the calibration procedure of the flight controller to ensure that the compass and IMU are calibrated before the flight.

Poor GPS Signal

The GPS antenna is shielded or disturbed by electromagnetic. You need to remove the shield, away from the interference source, and place the aircraft in an open area. In addition, the reason for this situation may also be that the GPS has not been powered on fora long time, the distance between the local and the last GPS positioning point is too far, or the microwave power switch is turned on before the UAV positioning.

At this time, you can try to turnoff the microwave power switch, turn off the system power, and turn on the power after 5 seconds to wait for relocation.

Warm Up Flight

It is found that the quadcopter cannot fly, please wait a few minutes to see if the situation has changed. Some drone models require some warm-up before take off, which often happens in cold weather.

Physical Damage

If there are any damages to the drones (such as internal components), for example, if they are wetted or damaged in any greater way, they don’t take off. Then, you may have to find a professional who knows how to repair the drone.

Ground Console Cannot Receive Data

Check whether the connector is loose or not connected, click the link button of the ground station, whether the serial port is set correctly, whether the serial port baud rate is set correctly, whether the data transmission channel of the ground console and the aircraft are set the same, and whether the GPS data on the quadcopter is imported.

As long as if there is a problem,the communication cannot be performed, and then reconnect after checking the correctness. If it still fails to connect after checking, restart the ground console and drone system power.

Drone Deviates from Course

Adjust the drone to fly and maintain altitude without human intervention. Secondly, check the wind direction and wind force, because the strong wind will also cause some problem,you should choose to take off the drone when the wind is light. Furthermore,check whether the balancer is placed properly.

Why is my drone not flying? Just like the drone not turning on, if any part is injured, it may make it can't fly.Drones are precision instruments, and any small changes in components can affect their flight and life.
