If you need to troubleshoot CAPTCHA every time you open an app on your phone, do you want to continue using it? So I felt like I used Sony's new a6400. If you look at the settings page and submenus to change important settings, it is difficult to use a non-solid mirrorless camera.
The Sony a6400 shares some features with the more expensive a6500 as a follow-up to the a6300 three years ago. There are many things such as stable image quality and fast hybrid AF systems. However, these positive features are buried under convoluted menus and awkward ergonomics. Everything about this camera is hidden under the menu, hidden by a warning, or not at all.
The main notable elements are real-time eye AF and tracking auto focus, updated image processor and 180 degree flip touch screen. With $ 899 for the body only, $ 999 for the 16-50mm kit lens or $ 1299 for the 18-135mm zoom lens, the a6400 has parts that can be an ideal small powerhouse for photo enthusiasts or video bloggers, It's easy.
Over the last few weeks using the a6400, I noticed that I have a good quality camera, not a compact mirrorless camera that changes in the game. “/>
- Intelligent and versatile auto focus system
- Excellent image quality
Small size Body
- No IBIS
- Sony's menu system is still messing The tiltable display is not clear and does not work in the menu
- Shortened battery life  Most of the improved parts of the a6400 include updated hybrid autofocus systems with more focus points; A total of 425 contrast and 425 phase detection points are provided to keep the 169 contrast points of the a6300 and a6500 at their best. You can attach candles to Sony's top full-frame camera, which can account for 84% of the image area and 93% of the Alpha A9.
Sony claims a 0.02 second focus and is quick to auto focus on the a6400, reacting instantly to half-pressing the shutter button and accurately identifying the target for most of the time.
The real meat of the new AF system of the a6400 is Sony's new real-time eye AF and tracking AF function. Real-time tracking of the a6400 uses Sony's algorithms and artificial intelligence to recognize and follow your subjects.
Similarly, "Real-time Eye AF" uses artificial intelligence to track the eyes and body of the subject and is updated to support the animal at the end of the year. Both of these features are useful for portraits where the model can be moved gradually or completely to other areas of the frame.
If you enable Real-time Eye AF, you can customize your photo as you follow your subject with the camera. If your subject is out of position, you can focus again and adjust settings each time.
But before you can do either of these, you really need to turn it on and it is not enabled by default. It should not be that hard, is it? 14 still picture settings ( using the navigation buttons alone  added 14 pages for video ) enabled continuous autofocus, eye and subject tracking enabled. In March 2019, Sony does not allow Alpha camera touchscreens to work in the system menus for unknown or unintelligible reasons.
When you do: It is solid. That did not change late in Sony's alpha camera. The a6400 is no exception and uses the same image sensor as the a6500. If color pop-ups, objects, and topics are clearly visible, ISO can be set between 100 and 32,000 in native mode, and ISO can be scaled up to 102,400 for dimmer scenarios. Most shots look great on the test scene, but the quality around ISO 12,800 falls noticeably and the details look stained. This effect is reduced in RAW images compared to JPEG (RAW is always better to edit). Expected due to additional data available in the file.Superior image performance in most scenarios
Video producers have a 6400 S-Log 2, S-Log 3, and Hybrid Log Gamma (HLG), but it is not the best fit for video, it also has a 4K 24/30 fps shooting mode and looks great, but does not have a headphone jack.
In addition, the a6400's SD card slot supports only the maximum UHS-I speed, which means that if you are using the latest UHS-II SD card, it is faster than the previous version
When you press and hold the shutter button in 11 fps continuous shooting mode, the buffer of JPEG standard 116 frames or RAW compressed image 46 frames is reached when writing to the SD card. But it is much less compared to the 300 JPEG and 107 RAW buffers of the a6500.
Nailing the a 6400's video recording capability in the tube is the lack of image stabilization in the body. This is the biggest difference between the a6400 and the a6500, and the value There is. Lack of stabilization inside the camera means fortunately that about 30 Sony lenses have to rely on the lenses they have and their own stabilization functions.
Bad rolling shutter occurred when recording video. Simply rotating the camera will show a jelly-like motion, but a clear 4K image will be displayed.
The a6400's 921k dot resolution display is brighter and clearer and can move 180 degrees to the Selkie location, but there is no complaints. In addition to the lack of touch controls in the menu, if you try to get a 180 degree position completely, the viewfinder eye cup will hit the screen. You can solve this problem by sliding the eye cup, but you can lose the eye cup now.
It is difficult to use a6400 for vlogging due to the hinge design. Video producers often place a shotgun microphone on a hot shoe mount on the camera. When you flip the screen upwards, the microphone completely blocks the screen and becomes useless. This solution is an articulated screen with a hinge on the side of the camera, but Sony needs to redesign the microphone and USB input on the left side of the camera.
, It is a good idea to set the programmable "C1" button as the video recording button. It is just next to the shutter button and is a lot awkward than the default option in the center of the thumbwheel.
The compact camera body is one of the most important things for a mirrorless camera that receives a spotlight in a DSLR. However, catches usually leave the unbalanced camera with a light grip by increasing the weight again. Ultimately, the a6400 works best with smaller lenses, such as the Super Wide Angle E 10-18mm F4 OSS Lens or the Compact Zoom Vario-Tessar T E 16-70mm F4 ZA OSS Lens.
Otherwise, if you choose heavy attachments like the $ 2,200 FE 2.8 / 16-35 GM zoom lens that you tested the camera, the a6400's small grip will feel too much inconvenience. Glass. Most of the grip faces of the camera are filled with buttons, so there is little space for the user wearing his or her thumb and gloves. I myself and some of my video team colleagues felt that the a6400's small grip was insufficient and uncomfortable.
I realized that attaching a hot shoe flash while shooting and attaching a zoom lens at the same time can be more difficult to handle. The larger lens was switched to Carl Zeiss wide angle 24mm f / 1.8 lens. This is where the a6400 shines. Mainly because of weight loss. It can now be felt as if there is a powerful and wobbly tool available to hold the camera in one hand.
The body of the a6400 is weathered by moisture and dust like the a6300 and a6500, but only large, expensive full-frame lenses from Sony are weather sealed, so you should check the weather. You can use the lens to shoot at the next heavy rain.
Battery life is another matter. Since the a6400 uses the same battery as the 3-year-old a6300, it has been rated 360-degree shooting. It turned out that some of his friends died during the photo shoot. Fortunately, it is relatively easy to find a third-party version of this battery, so it's a good idea to have a few spare sets when storing it in your camera bag.
The camera is well-priced considering the robust image quality and specifications. I was impressed with real-time tracking AF capability and focus time. But it is not absolutely perfect. Some of the new features of the a6400 (features such as real-time tracking) are particularly interesting for cameras of this size and price, but flaws such as the screen and menu system are a hindrance.
It feels like Sony has reached the end of what it can do with this camera design. The a6400 has almost the same physical design as the NEX camera, which debuted nearly ten years ago, and has trouble adjusting to new style of video blogging, such as larger lenses or video shoots.
Sony has updated the technology inside the APS-C camera, especially the autofocus system, but now it needs to pay attention to body and user interface. If this is done correctly, it can be the best enthusiast-like camera for photos and videos.
