This camera can also surf the Internet wirelessly. Evaluation of Sony Sliding Card G3

From the moment the digital camera was invented, the way people shared images was doomed to be greatly changed. It conveys infinite colors and light and shadow in an invisible way, which is the charm of digital technology. The gradual popularization of wireless network in our life has further narrowed the communication distance between people. Nowadays, digital cameras and wireless networks have begun to be more deeply integrated. For example, Sony Cyber-shot DSC-G3 is a digital camera with wireless Internet access.

G 1, the pioneer of G series, was once so unique in Sony Cyber-shot digital cameras, with explosive innovation in appearance and function, but it was this innovation that made it difficult to adapt to the market temperature for a while, and the limelight soon passed. Now the Cyber-shot DSC-G3 is reloaded and returned, which makes the wireless Internet access function simpler and more practical with a slider shape closer to the fashionable T series. Will it be in Gensonnie? Wireless sharing type? Is the camera hot again?

Cyber-shot DSC-G3 can browse the web through WiFi.

The new Cyber-shot DSC-G3 has a built-in web browser, which can browse ordinary http web pages and perform some simple information interaction operations on the pages. Of course, conveniently uploading photos to the Internet is the core of Cyber-shot DSC-G3 wireless sharing.

"Product advantages:

1, exquisite appearance and simple operation.

2. Wireless network function brings convenience for photo sharing.

3, the screen display effect is good

4. The autofocus response speed is fast.

"Product disadvantages:

1, random battery capacity is small.

2. The fineness of the preview is not high.

When Sony G 1 was launched with a chubby appearance, many users were very surprised, and many users had a very bad first impression on it because of this appearance. As the saying goes, success is Xiao He and failure is Xiao He. Today's Cyber-shot DSC-G3 no longer challenges most people's aesthetic orientation at this point. Lighter and more fashionable than G 1, the sliding body is very close to T series products. I believe that most young and fashionable consumers will like it at first sight.

In fact, the well-defined appearance and clean sliding handle are very harmonious, while the black metal body can inadvertently? Is it cool? It feels simple and bright.

The 3.5-inch wide touch screen of Cyber-shot DSC-G3 has a display resolution of 920,000 points, and can display photo thumbnails of about 365,438+0,000 pixels point to point, so the image display quality brought by it is far more delicate than the 230,000-point display screen of a general digital camera. Of course, playing photo slides on HDTV through HDMI interface is another high-quality photo sharing method of Cyber-shot DSC-G3. In practical use, the screen viewing angle and brightness of Cyber-shot DSC-G3 are no less than those of other digital cameras, but the preview image resolution of Cyber-shot DSC-G3 is not high enough, so that the image seen during framing has obvious sawtooth feeling.

The screen of Cyber-shot DSC-G3 is operated by touch (click here to view a larger image.

)

Touch screen makes the shooting and setting operation of Cyber-shot DSC-G3 more intuitive, and reduces the number of buttons on the fuselage. At the same time, it also creates conditions for the photo graffiti function. When used for web browsing, the touch screen is certainly more comprehensive than the conventional button operation interface. But in the process of using it, I can't help but think of Apple iPhone, which also has WiFi connection function. Sony Cyber-shot DSC-G3' s single touch screen still needs to click on the virtual button on the screen. Compared with iPhone, Cyber-shot DSC-G3 is still inconvenient to zoom in and turn pages.

Cyber-shot DSC-G3 supports multiple photo display modes, making it easier to organize a large number of photos.

Cyber-shot DSC-G3 is based on a large-size display screen, which can display pictures in various ways, such as shooting date and portrait type. This also provides an effective way to organize a large number of photos for Cyber-shot DSC-G3 with built-in 4GB memory.

In fact, there are many digital devices that support WiFi connection now, but some of them are not optimistic about their practicality, or eventually become furnishings because of the limitation of network bandwidth. In contrast, it is still a positive idea for cameras to share photos with WiFi.

Cyber-shot DSC-G3 can browse ordinary http content.

Cyber-shot DSC-G3 has a built-in NetFront V3.4 browser and an embedded Adobe Flash player. Therefore, Cyber-shot DSC-G3 can normally browse the general http content including Flash, and can perform some simple information interaction actions on the page, such as registering, logging in, posting comments or sending and receiving emails, and the browser can also record the login password. Cyber-shot DSC-G3 supports the https protocol when uploading photos to online photo albums to ensure the security of account information and photos.

Cyber-shot DSC-G3 can upload and browse photos.

The Picasa online photo album we tested can log in, upload photos and browse the photo album normally, which is also the default online photo album of Cyber-shot DSC-G3. In addition, you can log in to MSN space to upload photos through Cyber-shot DSC-G3, but this login is in mobile mode, and the functions that can be realized will be limited. Therefore, other online photo albums that do not support mobile devices may not log in normally.

Cyber-shot DSC-G3 can send and receive emails online.

We can also send and receive emails through Cyber-shot DSC-G3, and we can send photos stored in the camera as email attachments. The network access speed of Cyber-shot DSC-G3 depends on the connected wireless network, but the overall response speed is good in mobile devices, but it is limited by the resolution of the display screen, so it is not convenient to zoom and scroll web pages.

In addition, Cyber-shot DSC-G3 can also enjoy wireless photos through devices that support DLNA standards.

In general photography function, Cyber-shot DSC-G3 reduces the difficulty of taking beautiful photos as much as possible and increases the probability of taking successful photos through various advanced identification and optimization functions.

Cyber-shot DSC-G3 supports optical image stabilization and dynamic range optimization.

The optical anti-shake function of Cyber-shot DSC-G3 can be used not only when shooting still photos, but also when shooting videos, which is more comprehensive than the optical anti-shake function of general cameras. The dynamic range optimization function preserves as much details of highlights or shadows as possible for shooting in a high contrast environment. Although according to our test results, this small digital camera Cyber-shot DSC-G3 still has no advantage in imaging latitude.

Cyber-shot DSC-G3 provides automatic scene recognition mode.

Face detection and smiling face recognition functions of Cyber-shot DSC-G3

Now all major camera brands have developed their own automatic scene recognition mode, which saves a lot of trouble for users to take pictures. Sony's iSCN+ mode is more interesting, which can help users to take one more photo in different ways in some special modes and increase the probability of successful shooting.

Password lock function of Cyber-shot DSC-G3

Password lock function is also a special additional function of Cyber-shot DSC-G3 as a camera with built-in large-capacity memory. This function can prevent private photos from being accessed maliciously, which is not surprising in today's information security crisis.

In the response speed test, we use the built-in storage medium of Cyber-shot DSC-G3. Post-shooting processing time in the project refers to the time required to release the shutter until the next preview screen appears on the screen and get ready for the next shooting; Playback transition time refers to the time from clicking the screen to the next photo being clearly displayed on the screen in playback (browsing) mode. When testing the focusing speed, we focus on the black-and-white picture displayed by the LCD with a distance of 1 m. Other settings of the camera remain in the default state.

Dynamic performance test. We refer to the test method provided by CIPA DC-002-2003 standard, and use a fully charged lithium battery (model NP-BD 65438+620mAh, 3.6V) and an 8GB Sandisk Extreme III SDHC1GB Sony memory stick Produo Apache150xSD/Kloc-0. The key points of the test are: P mode shooting is used during the test, and the photo storage format is the largest and most detailed. The built-in flash is used once every two shots with an interval of 30 seconds. During this period, perform at least one full-focus zoom operation, and turn off the power for more than 5 minutes after every 10. In addition, during the test, the anti-shake function is always on and the automatic power saving function is always off. The LCD is used to view the scene and keep the brightness of the display screen at the highest level, and the power mode is set to Ni-MH battery. When the camera is automatically turned off due to insufficient power, the test process ends.

The following are the test items and results of reaction speed and dynamic performance, which will be slightly different from the following results due to the different environment and photographer's habits in actual use:

200 photos, or about 30 minutes of web browsing.

According to the test results, the Cyber-shot DSC-G3 with periscope lens has speed advantages in autofocus and continuous shooting response, and the shutter lag is almost negligible. However, the post-processing time of a single photo taken by Cyber-shot DSC-G3 is long, and the process of thumbnail reproduction also has obvious time lag when playing back photos. In addition, the random battery capacity of 620mAh is too small for the large-screen Cyber-shot DSC-G3.

The camera's ability to express imaging details can be reflected by resolution test. In the imaging resolution test, according to the method provided in Imatest software reference, under the illumination of 5000K standard color temperature lamp (the color rendering index is greater than 95%), we used the test prototype to test the ISO 12233 test target for many times. The focal length used is equivalent to 50mm of a 35mm film camera, and the sensitivity is ISO 100. The following are the test results of Cyber-shot DSC-G3.

Horizontal imaging resolution of Cyber-shot DSC-G3

Vertical imaging resolution of Cyber-shot DSC-G3

For the model with/kloc-0.0 million pixels, the highest resolution performance of Cyber-shot DSC-G3 about 1800LW/PH is not excellent, and the key reasons that limit its imaging resolution performance are imaging noise and lens dispersion.

When analyzing and testing the imaging color of the prototype, we use it to shoot the X-rite ColorChecker SG color test target at the sensitivity of ISO 100, and then analyze the color, and we can get the data such as imaging color error and white balance error. The value of the white balance error in the list is the color temperature error of the medium gray block, and the closer this value is to zero, the better. If this value is positive, it means that the imaging tone is cold, and if it is negative, it is the opposite. 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.

Imaging color error of Cyber-shot DSC-G3.

From the color temperature error of automatic white balance, it is difficult for Cyber-shot DSC-G3 to have ideal color tone performance under artificial light source, and the cool color tone tends to be obvious. Judging from the imaging color error, the imaging color of Cyber-shot DSC-G3 in standard mode is very saturated, even the skin color is dark, so it is easy to shoot the subject very bright.

We use the automatic mode of Cyber-shot DSC-G3 to shoot the same group of still lives, and observe their exposure and imaging noise at different ISO sensitivities. The following is a photo slice with magnification of 100% at various speeds:

As can be seen from the above reference pictures, the performance of Cyber-shot DSC-G3' s imaging noise control ability is indeed lacking, and even in ISO 200, the picture clarity is obviously reduced. Even in ISO 100, flaky color anomalies are easy to appear in solid color areas.

Judging from a large number of test samples, the imaging color of Cyber-shot DSC-G3 is really bright, which is more pleasing to the eye when shooting general still life and scenery. However, when shooting at high sensitivity in dark environment, the picture details and shadow areas are poor. Of course, the combination of high sensitivity and optical anti-shake function can really reduce the probability of taking dynamic blurred photos by Cyber-shot DSC-G3. The following are some test samples of Cyber-shot DSC-G3:
