Panasonic GX 1 has good resolution.

In the test, we used Panasonic GX 1 equipped with 20mm F 1.7 lens, and took samples of ISO 12233 resolution standard board (4000 lines) under various apertures, and tested with Imatest software, and finally got the best resolution value. The following is the best resolution test result of Panasonic GX 1:

▲ Panasonic GX 1 resolution performance

According to the test results, the best resolution of Olympus E-PL3 is good, with the highest resolution of 2300 lines in JPG direct format and 2700 lines in RAW-JPG format.

▲ JPG with the best resolution for direct visual inspection.

▲ Visual inspection of the best resolution from RAW to JPG

From the visual results, it can be seen that the vertical resolution of Panasonic GX 1 in JPG format is about 2400 lines and the horizontal resolution is about 2400 lines, while the vertical resolution in RAW-JPG format is about 2600 lines and the horizontal resolution is about 2600 lines. It seems that the resolution performance of Panasonic GX 1 is really good.

The actual shooting effect of Panasonic GX 1 is also good.

Resolution test can let us know the theoretical definition of a camera, but it is best to see if the photo can reach the definition we want.

▲ Clarity test environment

We used Panasonic GX 1 to take this photo in a standard evaluation environment. The lens used is 20mm F 1.7, the shooting parameter is F8 aperture under A file, and the sensitivity is set to ISO 160. For the convenience of comparison, we 100% cut off four parts of the sample (the red box area above) for observation.

▲ Sample 100% enlarged screenshot

As can be seen from the above proofs, the actual shooting clarity of Panasonic GX 1 is good, the details of the face and collar position are well preserved, and the purple texture behind the silk thread is also very clear, and the texture restoration of metal coins is basically satisfactory.

From the two aspects of resolution and clarity, Panasonic GX116 megapixel M4/3 image sensor really provides a strong guarantee for high image quality, and the overall clarity of the shot picture is satisfactory, which is a good level in the same level of micro-camera.

Panasonic GX 1JPG format shows good sensitivity.

The following scenario is the standard sensitivity test environment of IT 168 evaluation room. We fixed the camera on the gear platform of a heavy tripod and let the camera shoot the photosensitive effect of each gear motionless. After that, we cut the photo slices from the same position in the above picture, as shown in the red box, to see what the sensitivity of Panasonic GX 1 is.

▲ Sensitivity test environment

First, let's shoot a set of JPG slices with noise reduction turned off.

▲ Panasonic GX 1 sensitivity performance

As can be seen from the above slice, Panasonic GX 1 has a good high sensitivity, and the slight noise only appears after ISO800, and the noise obviously comes from ISO3200. On the whole, the available sensitivity of Panasonic GX 1 is ISO800.

▲RAW to JPG high sensitivity contrast

However, by comparing the high-sensitivity performance of JPG direct output and RAW to JPG, it can be seen that Panasonic GX 1 probably optimizes the high-sensitivity image quality in JPG direct output, while in RAW format, the available sensitivity is only ISO400, which is somewhat poor for a flagship product. It is recommended that you record as many photos as possible in JPG direct output format in dark environment.

Panasonic GX 1 automatic white balance is blue-purple.

Clarity and high-sensitivity imaging are important manifestations of image quality, and the color performance of Panasonic GX 1 is also worthy of attention. One is to see whether its white balance can accurately restore the original color temperature of the object, and the other is to see what theme its overall color tendency is more suitable for.

▲ Color test environment

In order to understand the imaging style of Panasonic GX 1, in the color test, we let Panasonic 20mm F 1.7 lens, set automatic white balance and manual white balance to shoot standard color cards respectively (the red box area in the above picture is the color test range), and get the final data through imatest software:

▲ Panasonic GX 1 Manual White Balance Test Results

The test chart reflects the difference between the actual imaging color value and the ideal value of Panasonic GX 1. The part surrounded by gray lines in the figure is the color gamut range of Panasonic GX 1. The square color block in the test chart is the ideal color value, and the circular color block is the actual shooting value. Among them, manual white balance exceeds sRGB color gamut 18.3%, and Panasonic GX 1 has moderate brightness, which can be used for post-processing and direct output. At the same time, manual white balance is very accurate, suitable for taking photos of various themes.

▲ Panasonic GX 1 Automatic White Balance Test Results

In terms of automatic white balance, we can see that Panasonic GX 1 is sensitive to blue and purple, which is very suitable for taking landscape photos, but when taking other styles of photos, we should try to use manual white balance to compare colors.

Panasonic GX 1 video autofocus is not strong enough.

The high-definition video shooting ability of the camera has now become one of the important performances that have attracted much attention. Panasonic GX 1 can not only focus automatically, but also have real-time continuous focus tracking function. Let's see the actual effect.

Let's watch a video shot with Panasonic GX 1 autofocus tracking:

▲ Panasonic GX 1 autofocus tracking test

As can be seen from the above video, the automatic continuous focusing of Panasonic GX 1 is still relatively fast. During the whole movement of the train, there are many behaviors of focusing on the front of the train, but in the process of automatic focusing, we are hesitant and can't always ensure the clarity of the front of the train.

In addition, when shooting still objects, there will also be some cases where the subject changes due to composition hesitation and scene change. In this case, can Panasonic GX 1 auto focus quickly? Let's do further tests.

▲ Panasonic GX 1 autofocus test

In the whole autofocus process, we can see that Panasonic GX 1 still showed some hesitation, but finally succeeded in focusing on a new subject, which is more in line with the consistent style of a single camera and still has a certain gap compared with the real DV.

On the whole, the high-definition video shooting function of Panasonic GX 1 is still very practical, and it can be used for automatic real-time continuous focusing, but the focusing stability of the shot pictures is not high, which is obviously different from the general DV. It can be used as a record of daily life, but shooting more professional short films is still insufficient.
