Sony Camera Focus Problem

Sony Camera Focus Problem


When it comes to photography, the Sony camera delivers incredible images. But sometimes, the device may not provide an accurate picture due to the focus issues.

In this guide, I will discuss the potential reasons for the focus problem and the solutions. So, let’s dive into the discussion…

Reasons For The Sony Camera Focus Problem 

These issues may disturb your camera not focusing automatically or manually. Read carefully-

Dirty AF sensor 

I first want to highlight the camera’s dirty AF sensor. It is the thing that measures the distance between the subject and the camera. It collects information about the matter and sends them to the main body, where the rest of the functioning part is done. 

If the AF sensor is dirty, it cannot detect the concern and fails to command the camera. 

Wrong Mode 

Secondly, the focusing problem happens due to selecting the wrong way. For example, you want to use the AF mode or MF mode to capture an image or a running thing but switch to MF mode or AF mode by pressing the button AF/MF on the body. This situation happens when you unintentionally move the key to the wrong position. 

Dirty Lens Contacts

Thirdly dirty lens contacts can be the foe for your focusing problem. The lens and the camera share information with each other through contacts. It is situated at the point where both of them meet. Now the question is, how does dirt get inside? Well, the answer is at the time of changing the lens. 

You use different types of lenses for other purposes. While setting one by removing the previous ones, dirt can access the built home in the contacts. This uninvited guest prevents your lens from contacting your camera, and the issue happens. 

Low Light Sony a9

The camera cannot concentrate on the subject because of the low Light. Therefore, inserting a sufficient amount of Light is necessary to take a good picture. If the Light is too low, the camera cannot get enough brightness, and the view would be blurry. 


Contrast is highly valued for the camera’s good performance. Photos will be Sharpe and accurate when there is much difference. A deep contradiction of black and shine is perfect for your camera.  

If you are in a place where the required divergence fails, your camera cannot find anything. 

Weak Knowledge About Camera 

You should have a good command over your camera. If you are not an expert and do not have deep knowledge of the camera, then the foremost thing to happen is you will not use it properly. It has many options like AF mode and MF mode, each for various purposes. 

It would help if you used options on the correct basis. Otherwise, you will not get results. 

Wrongly Set Lens  

The lens should be decently set to the camera, or it will malfunction. Details about the matter pass through the lens contacts to the camera. So, it is necessary to connect the lens to the device exactly.  

When you set the lens to the body and rotate, you will hear a click at the end of the circle. It means that the lens is well positioned, and you will not hear a click sound if it does not. 

Sometimes a lens cannot transfer ideas to the instrument if it falls to the ground.

Closer Issue 

The distance can be a happening of not focusing on your concern. The camera needs a minimum interval for seeing, measuring, collecting, and capturing things. It does not search and receive data about the subject matter when you are too close to it. As a result, you will get an obscure photo.


You often notice that your instrument does not focus on the main issue and only detects irrelevant circumstances. It means that the sensor and the lens fall apart from working together. It would be best if you had fine-tuning in this experience. 

Unwanted Subjects Before the Primary Target

You see a person behind the gate or an animal in the cage that seems interesting to you to capture. So you focused the camera on the target and grabbed it. But you get puzzled when you see the take picture. 

It only focuses on the gate or the cage and does not give concentration on the main thing. Why? Because the device only sees something which is in front of it. It escapes the individual or the beast as they are behind the barrier or the cell. 

Contrasted Design

The camera does not find the subject in the field of highly contrasting design. The patterns like sky crapper windows, reflective cars, or black and white colored strips prevent the camera from searching for the desired thing by moving them aside. 


You have seen the problems your camera may face. Now it is time to give sufficient time to the solutions. So, have a look-

Erasing Dirt from the AF Sensor 

How do you clean dirt from your sensor when you see it is full of dust? Is it difficult? No, it is not. You can wipe unwanted guests from the sensor through a blower. First, set your camera to the sensor cleaning mode after pressing the menu button and blowing dust. 

Setting Right Mode 

Firmly set your mind on what kind of picture you will take. For example, if you want to take an image of a constant subject matter, then use AF-S mode, and for moving things, use AF- C mode. But confirm the AF/MF switch is in the AF mode. 

If you want to use the device manually, displace the AF/MF button to the MF mode. 

Cleaning Lens Contacts 

Remove the lens from the main body and use a dry and clean cloth to set the dirt free from the lens. But ensure your hands don’t touch the lens directly while cleaning it or cause scratches. Otherwise, it leads to corrosion which makes the instrument stop functioning. 

Search for Abundant Light

Do search for the area where the sun gives Light for much time. Sufficient Light fulfills the camera’s hunger, and it will work consistently. It makes your picture vivid and lively. 

You can use the flashlight if you do not find the necessary Light. Then press the shutter button halfway to determine the content and click again for the final result. 

Select Contrasted Areas

Make sure the area you go to, with much black and shadow disparity, is there. It is needed as it helps the device identify the subjects in ample space. 

Make A Distance to the Subject.

Maintain a gap of 15 to 20 feet distance from the subject. Use a more robust lens when your target is too far, and select the lens made for close range when the thread is near. 

If you use AF mode for photography, choose macro AF mode for the touchable target allowing a distance of 6 feet. 

Set the Lens Properly 

The lens should be orderly set. Otherwise, it will not do its work. Insert the lens in the destinated place of the camera and rotate until you hear a click sound. 


When it is time for calibration or fine-tuning, you don’t have to worry about how to do it. Sony cameras consist of easy access to fine-tuning. To do this, press- 

Fn button-then select white balance- select the desired things. Here you will find everything you want. For example, you can make the image radish or bluish, etc. 

Order the Camera for the Target 

When unessential matters hamper your focused goal, you can keep them apart by zooming and making the camera identify the item. Zoom the camera to get more visual, press the button halfway to let the camera target the issue, and lower the stud fully to capture. 


Your camera is the most valuable thing to you as you take pictures and videos to make a memory. You can get rid of the problems regarding your camera when you follow my instructions and can go to places from near to far with your camera.
