The thinnest Sony TX55 in the history of iPhone4.
Sony T series products surprise us every year, so this year's new product release is also expected. The innovative Sony card TX55, which still hides half a face behind the guitar in front of us, finally unveiled its mysterious veil in 2065 438+0 1. 8. 8. Although TX55 continues the classic slide design of Sony T series in appearance design, the fuselage is still made of metal, and it seems that nothing has changed from the appearance alone. However, TX55 further reduced the size of the fuselage, and the thinnest part of the fuselage was only 12.2mm, making it the smallest and thinnest digital camera card product in the world.

Details of TX55 appearance
Sony TX55 is made of metal matte, which makes it feel full in your hand. It uses a 2.3-inch Exmor R CMOS image sensor, and its effective pixel is 1620. With the carl zeiss Vario Tessar periscope lens, it has the optical anti-shake function. Because Sony TX55 uses a 3.3-inch touch screen with 1.23 million pixels, which occupies the whole back of the fuselage, the design of its control buttons is quite simple. Only the switch, shutter and zoom lever are set on the top of the fuselage, and other operations are completed through the touch screen. In terms of battery, TX55 adopts 630mAh rechargeable lithium-ion battery. As for memory card, Sony's own M2 memory card and Micro SD memory card are supported.

Sony TX55 built-in sharpening is obvious.
In the resolution test, Sony TX55 photographed the ISO 12233 resolution target (line 4000), and analyzed the final data with Imatest software. The best resolution of Sony TX55 is 2876LW/PH, which is similar to that of SLR. Next, we will further observe its performance in resolution by actually shooting visual samples.
▲ Sony TX55 wide-angle resolution test results
▲ Sony TX55 telephoto end resolution test results
▲ Sony TX55 resolution visual sample
The above picture is a resolution sample 100% screenshot taken by Sony TX55. The resolution proof of the wide-angle end is at the top of the picture, and the resolution proof of the telephoto end is at the bottom (enlarge the original picture). Although the resolution of Sony TX55 is as high as 2876 lw/pH, it can be seen from the screenshot that Sony TX55 has obvious internal sharpening phenomenon. In addition, from the actual visual samples, we can also observe that there is obvious dispersion in the edge position, which is the main reason that affects the performance of edge details in the imaging picture.
Sony TX55 definition test
We used Sony TX55 to shoot the actual sample in ISO200 gear, and intercepted its four parts with 100% to observe its performance in detail.
▲ Schematic diagram of clarity and 100% interception position.
▲ Shutter: 1/6 seconds/aperture: F4.5/ sensitivity: ISO200/ white balance: auto/focus: 19mm.
The above slices are ISO200 proofs 100% screenshots taken by Sony TX55. From the slice, we can see that the imaging details of Sony TX55 are somewhat disappointing. The details of the whole picture are seriously lost, especially from the face slice in the second part, the details of the facial texture part have been completely lost, and there are obvious particle noise and color drift in the picture.
Sony TX55 Color Performance Test
In the contrast test of color performance, we use Sony TX55 to shoot the X-rite ColorChecker SG color test target at ISO 100 sensitivity, and then analyze the color, and we can get the imaging color error data.
▲ Illustration of Sony TX55 color performance test results.
This test chart reflects the difference between the actual imaging color value and the ideal value of Sony TX55. The part surrounded by gray lines in the picture is the color gamut range of the camera under test. In the color error diagram, the squares in the Lab color gamut coordinates represent the ideal color (standard color) of the subject, and the circles represent the imaging color of the camera under test. Sony TX55 exceeds the sRGB color gamut by 20.4%, and the color reproduction of the image is high. Judging from the trend of sRGB color patches, red is relatively more expressive.
TX55 Noise Control Performance and More Creativity
In the noise control ability test, we used the same settings, sampled the sample cabinet at the same position, and took a 100% screenshot to observe the signal-to-noise ratio performance of Sony TX55 gears. We should not only compare the graininess in the picture, but also consider whether there is color drift and whether the details of the picture can be well preserved.
▲ The picture shows the schematic diagram of the sampling cabinet for noise control capability test 100% interception position.
▲ The picture shows a screenshot of Sony TX55 real-time sample cabinet 100% comparison.
The lowest sensitivity of Sony TX55 is ISO 100. As can be seen from the screenshot above, the noise control performance of Sony TX55 is not as good as the official propaganda. From ISO 100, identifiable particle noise appeared, and the appearance of noise increased with the increase of sensitivity gear, accompanied by obvious color drift. Excessive sharpening in the machine makes the detail loss of its picture very serious. Use the recommended sensitivity.
Photo effects provide more creativity.
In terms of creative functions, Sony also provides users with seven photo effects, such as HDR painting effect, rich tone black-and-white mode, miniature landscape effect, toy camera, local color, soft and bright tone and popular color, so that users can get creative shooting effect without post-image processing. It is worth mentioning that when Sony TX55 uses the photo effect mode, you can set the modes of HDR painting, miniature landscape and toy camera in a more detailed style through the setting menu.
▲ Sony TX55 provides users with 7 photo effects.
Performance of Sony TX5 wide-angle and telephoto distortion control ability
Sony TX55 has a 5x optical zoom lens with obvious distortion at the wide-angle end. The data given by Imatest test is that the wide-angle distortion rate is 2.74%. Relatively speaking, the telephoto end distortion is slight, and the data given by Imatest test is 0. 13%. In terms of optical loss, the wide-angle end of the machine has obvious optical loss, and the telephoto end has been improved but not completely eliminated.

IT 168 evaluation center's viewpoint
Judging from the products released by Sony in past dynasties, all digital cameras with the number "5" belong to its innovative products. This world's smallest and thinnest fashion digital card is named TX55, which shows that Sony attaches great importance to it.
▲ The digital camera with the number "5" belongs to its innovative products.
Although the appearance design of Sony TX55 has not changed much, and great efforts have been made in functional design, its performance in image quality has not brought us any surprise or even a little disappointment. Different from Sony's super noise control performance, in the standard test environment of the evaluation center, the image quality of Sony TX55 is somewhat unsatisfactory, and the trace of built-in sharpening is too obvious, which affects its performance in resolution and noise presentation.
▲ It is very eye-catching to have a digital camera smaller than a mobile phone.
Although its performance in image quality is slightly insufficient, I believe that its petite and fashionable body will still be welcomed by the majority of female users, and it is also very eye-catching to have a digital camera smaller than a mobile phone. Of course, if you love fashion, you won't miss this opportunity to show it.
