Evaluation of Meizu MX3

Lens quality

In actual shooting, we will find that the image quality of MX3 is quite good, with sharp imaging and no red shift. Although the edge image quality has declined, the loss is within an acceptable range. For a lens with an aperture of F2.0, this has performed very well. Compared with the previous proofs, we will find that this lens is actually better than Lumia 920 lens, and it is obviously superior in resolution. The anti-glare ability of a new generation of cameras has been greatly improved, and MX3 is no exception. When the front is backlit, the picture can still maintain good contrast, and there is no obvious fogging phenomenon. However, the side backlight will appear glare at a certain angle, but the problem is not big, so you can avoid it slightly when taking pictures.

concentrate

The default focus of MX3 is the center point. After the new composition of the mobile phone, the focus will be completed automatically. You can also change the focal length and focus by touching your fingers. The focusing speed is neither fast nor slow, and the focusing accuracy is not bad. Meizu official also specifically stated that the use of "zero delay photography" will automatically filter the best pictures in the past 1/8 seconds after pressing the shutter. I have to say that this is a very encouraging idea. But in the actual experience, we will find that the success rate of focusing is low. The reason comes from the operation process.

The actions of MX3 focusing at one time can be divided into: the first step is autofocus or manual focus selection and autofocus, and the second step is to select the shutter button or use the physical button with reduced volume to trigger the shutter. There is a time difference between these two movements, which is much greater than 1/8 seconds, and in this time difference, the shaking of the hand will lead to out of focus, or the movement of the subject will lead to out of focus. How can I do two actions at the same time? The solution of MX3 is that pressing the screen for a long time after selecting focus will trigger the shutter. This method looks like an action, but it takes time to press it for a long time, which can't effectively improve the shooting efficiency and reduce the negative effects caused by hand shaking. This design is more likely to lead to macro shooting failure, because the depth and slight jitter of macro shooting will lead to out of focus. But it doesn't mean that you can't take snapshots or macro, but the success rate will be lower.

MX3 has no metering option, but there are actually two metering modes. When you pick up the phone and use autofocus without touching the screen, the metering at this time is global metering. At this time, metering is basically accurate, but it is not suitable for complex lighting environment. This kind of focusing photometry is suitable for novice users who only know how to poke the shooting button, and can also cope with most outdoor scenes. When you touch the screen to focus, you will find that the metering will change accordingly, which is the linkage mode of focusing and spot measurement. This mode provides greater photometry controllability, excellent control can shoot better pictures, otherwise it is easy to fail, so it is not suitable for novices. MX3 also provides an exposure compensation range of plus or minus 3EV, which is convenient for personalized creation, but the step size is 1EV, and it would be better if it is 0.5EV or 0.3EV. ..

Built-in related applications

Compared with the shooting program that comes with MX2, there are some changes in the interface. The operation is relatively smooth, such as double-clicking the exhaled exposure compensation and HDR menu, and the design is simple and convenient. The functions related to control have not increased much. There are still only four white balance options: automatic, fluorescent, daylight and incandescent, and there is no metering mode option menu, which is not "professional". Stupid is not thorough enough, but it can be more stupid.

The main progress comes from the addition of real-time filter function. What you see is what you get, which is very intuitive to use. There are basically all kinds of colors that Wenqing people like, suitable for sweeping streets and short stories. This is a very useful and practical function, and I want to praise it here. The fly in the ointment is that it costs more electricity than ordinary shooting. This function greatly increases the playability, which is the advantage of taking pictures with mobile phones.

White balance and color, image quality

MX3 adopts the "fourth generation white balance algorithm", but most of the time the imaging tends to be warmer, which is actually a more pleasing style, not a color cast. In fact, both iPhone and Lumia have this tendency. But MX3 is a little different, its color performance is conservative, not bright style. The performance of yellow and green is excellent, and we can see that the texture of green leaves and tiles is excellent [within the range of mobile phones], while the saturation of red is not enough, which should be related to the algorithm, because red is easy to overflow and is usually deliberately suppressed, just like putting monosodium glutamate in cooking. Blue performance is actually full, but it is noisy and criticized by many readers. The noise about the blue sky is not unique to MX3. Most models have them, but there are many MX3s. The color performance will be more full and bright in cloudy or low light environment. The actual shooting found that ISO kept within 200, and the picture quality was better, while ISO400 could retain the value of documentary shooting, and beyond 400, it basically lost its practicality.

The upper limit of the safety shutter of MX3 is 1/25 seconds. If the exposure time is higher than this value, ISO will automatically adjust. Because the aperture is F2, even in the case of low sensitivity, you can take some low-light shots. The highest automatic ISO can reach ISO 1300, but the picture quality is unacceptable at this time, but it can be properly "covered" by filters. How much has the image quality of MX3 improved compared with MX2? Let's look at it through a simple set of comparisons. It is easy to see progress and gap. Compared with MX2, it does improve, but compared with Galaxy S4 with higher pixels per inch, the gap is also obvious.

abstract

Years ago, the camera quality of MX3 was excellent, but now it can only be regarded as the upper-middle level. This year is the biggest progress in camera technology. There is no denying that MX3 has made obvious progress compared with MX2. Compared with the previous MX2 proofs, it is clear at a glance that Meizu's statement that it is "not what it used to be" is no problem, but it is not only Meizu that is not what it used to be, but the whole mobile phone industry. The progress of Meizu is not enough, and Meizu needs more progress. MX3 hardware foundation is not bad, and it can be further optimized, noise can be optimized, shooting efficiency can be optimized, and APP can be multi-functional.
