Compared with last year's product ZR 100, the most obvious improvement of this year's new product is that Casio ZR200 is equipped with a 1/2.3-inch high-speed back-illuminated CMOS image sensor with an effective pixel of 1665438+ million (ZR 100 is126558).
▲ Main performance of Casio ZR200
As can be seen from the main performance of the above picture, Casio ZR200 is characterized by not only a large zoom lens, but also a high pixel sensor, a 24mm wide-angle lens and a full HD camera function. Then, let's have a comprehensive understanding of the overall performance of this camera.
Casio ZR200 appearance
▲ Front view of Casio ZR200
Casio ZR200' s exterior design is quite satisfactory, and the fuselage streamline design is distinct. From the front, you can see its 12.5 times optical zoom retractable lens and flash, and at the same time, a non-slip strip is added to the handle.
▲ Casio ZR200 rear view
Casio ZR200 is equipped with a 3.0-inch ultra-high definition LCD night screen with 460,000 effective pixels, but it does not support touch operation. All the parameters in the shooting process should be set through the buttons on the back of the fuselage.
▲ Top view, bottom view and side view of Casio ZR200
Casio ZR200 mode dial can be seen at the top of the fuselage, with gears A, S and M, which are used to manually control exposure parameters. In addition, you can also see the power switch, shutter button, zoom lever and so on.
Casio ZR200 fuselage details

▲ Casio ZR200 battery
The battery compartment of Casio ZR200 is located at the bottom of the fuselage, and the SD memory card slot is also located in the battery compartment. The NP- 130 lithium battery that comes with you can take about 480 photos when fully charged, which can basically meet the needs of a day's travel shooting.
▲ Casio ZR200 interface
Casio ZR200' s fuselage interface is located under the side guard, equipped with HDMI high-definition output interface and USB data interface, which is enough for a card camera.
${PageNumber} Casio ZR200 resolution test
Next, let's take a look at the improved image quality of Casio ZR200 effective pixels. We use it to shoot samples under ISO 12233 resolution standard (4000 lines), and test with Imatest software to get the best resolution value. The following are the best resolution test results of Casio ZR200:
▲ Casio ZR200 resolution test results
From the above test results, it can be seen that the central resolution of Casio ZR200 is excellent, and the horizontal and vertical resolutions are above 2670 lines, but the horizontal resolution of the edges is very low. After analyzing the original image, the author found that the vertical lines of the edge image were obviously scattered. So is the difference rate of Casio ZR200 really as good as that tested? We need to do a visual inspection.
▲ Visual effect of Casio ZR200 resolution
As can be seen from the above figure, there is a certain gap between the visual results of Casio ZR200 and the software test results. Both horizontal and vertical resolutions are around 2200 lines. Although this result is not as good as the data obtained by the previous software, it is still above average in the camera.
Casio ZR200 definition test
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.
▲ shooting target
We used Casio ZR200 to take this photo in a standard evaluation environment, and the sensitivity was set to ISO 80. For the convenience of comparison, we 100% cut off four parts of the sample (the red box area above) for observation.
▲ Screenshot of Casio ZR200 resolution proofs 100%
As can be seen from the screenshot above, the image quality of Casio ZR200 is basically satisfactory. Observing people's faces, we can find that some texture details are slightly recorded, and the metallic texture on the surface of metal coins is partially preserved. Based on the previous resolution test results, we can conclude that the imaging quality of Casio ZR200 is basically satisfactory, and it is in the upper-middle position in the camera.
${PageNumber} Casio ZR200 High Sensitivity Test
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 slice from the same position in the above picture, as shown in the red box below, to see how the sensitivity of Casio ZR200 is.
▲ shooting target
The following is a screenshot of various sensitivities 100% of Casio ZR200. We can analyze the sensitivity performance of ZR200 from the figure below.
▲ Sensitivity performance of Casio ZR200 in various gears.
Casio ZR200 has no obvious image quality loss in ISO 200, but some image quality loss occurs in ISO400, and the noise in ISO800 increases obviously. Therefore, the maximum usable sensitivity of Casio ZR200 is ISO400, and ISO800 and above are only recommended for emergency use.
Casio ZR200 color reproduction test
In order to understand the imaging style of Casio ZR200, in the color test, we use automatic white balance and manual white balance to shoot the standard color card (the red box area in the above picture is the color test range), and get the final data through imatest software:

▲ Casio ZR200 Manual White Balance Test Results
This test chart reflects the difference between the actual imaging color value and the ideal value of Casio ZR200. The part surrounded by gray lines in the figure is the color gamut range of ZR200. 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, the manual white balance is only 8.3% beyond the sRGB color gamut, and the color recorded by Casio ZR200 is close to the real color, which is sensitive to red performance and suitable for shooting portraits. ?
▲ Casio ZR200 automatic white balance test results
In the automatic white balance mode, the color gamut of Casio ZR200 exceeds sRGB 9.4%, but the picture is obviously blue, more sensitive to blue, and the automatic white balance is inaccurate.
${PageNumber} Casio ZR200 sample display
Casio ZR200 lens has the optical zoom capability of 12.5 times, which is suitable for shooting a wide range of scenes. With HDR, HDR art and other filter functions, shooting becomes very interesting and artistic.

▲ Casio ZR200 sample
From the proofs, we can also see that Casio's ZR200 background blur function is very effective. Even if the lens telephoto end or large aperture is not used, the effect of shallow depth of field can be taken, which is impossible for many card cameras.

▲ Casio ZR200
Advantages:
12.5 times super zoom lens 24mm wide-angle shooting has many shortcomings such as HDR art, background 1665438+ CMOS image sensor with millions of effective pixels, small size and strong portability.
The image quality at high sensitivity is generally blue with automatic white balance. Editor's comment: Based on the above, we have clearly seen the advantages and disadvantages of this product. The author thinks that Casio ZR200' s super-large zoom lens and various shooting artistic effects will become the biggest selling point of this product, which will make many people fall in love with this camera at once. 1860 yuan's price is also relatively affordable, which is recommended by home camera users who travel frequently and love to take pictures.
