IT 168 evaluation telephoto digital camera has attracted the attention of digital camera users because of its large optical zoom ratio. In 20 10, the overall performance of the parents telephoto camera was further improved, and the effective pixel reached140,000, while Canon even broke the maximum optical magnification by 35 times, becoming the telephoto king with the leading zoom magnification. However, with the improvement of hardware parameters, we pay more attention to the image quality of products. This paper will analyze the five products listed this year, such as Canon SX30IS, Fuji HS 1 1, Oba SP-800UZ, Panasonic FZ40 and Kodak Z98 1, from the aspects of clarity, noise control ability, color saturation and white balance error and distortion control ability.

Comparison table of basic parameters of five telephoto products for more than 20 times.

From the above parameter table, we can see that in terms of sensors, except Fuji HS 1 1 equipped with CMOS sensors, the other four products all adopt traditional CCD sensors, while in terms of zoom magnification, Canon SX30IS leads with its optical zoom magnification of 35 times, Fuji HS 1 1 and Oba SP-800. In terms of effective pixels, except Fuji HS 1 1 stick to10.3 million pixels, all other products have reached the14 million mark. However, behind the overall improvement of hardware performance, does it also have excellent image quality performance? Let's wait and see.

The Leica lens next to Panasonic FZ40 has the best definition.

In the definition test of five products, we set the sensitivity value of these five products to ISO 100, and shot the ISO 12233 resolution test target under uniform illumination, and paid attention to the imaging resolution performance of these five products through the vertical resolution and horizontal resolution of 4: 3 scale photos:

Let's take a look at the performance of five products at the telephoto end. Judging from the standard proofs 100% screenshots taken by five products at the telephoto end, the sharpness performance of the five products at the telephoto end is very obvious. By comparison, Panasonic FZ40 has the best performance, followed by Canon SX30IS, Kodak Z98 1, Oba SP-800UZ, and the last one is Fuji HS 65438+. Combining the sharpness test results of wide-angle end and telephoto end, Panasonic FZ40 equipped with high-quality Leica lens won the test.

The picture is exquisite. Fuji HS 1 1 won this time.

In the test of noise control ability, we selected the lowest ISO gear in five products to take photos at ISO 1600 gear with the same settings, and intercepted the 100% screenshots of the same part in the test samples for comparison.

The following are screen details of each file of five products under ISO:

From the lowest position of the above five products to the sample of ISO 1600 100% screenshot, we can see that Fuji HS 1 1 has relatively delicate noise control ability, followed by Canon SX30IS and Panasonic FZ40, and Oba SP-800UZ has weak noise control ability. We recommend that the available sensitivity gear of Fuji HS 1 1 is below ISO800, that of Canon SX30IS and Panasonic FZ40 is below ISO400, and that of Oba SP-800UZ and Kodak Z98 1 is below ISO200, among which the noise of Oba SP-800UZ is particularly obvious.

Color saturation and white balance have their own characteristics.

Next is the color test. When analyzing the imaging color of the test prototype, we use the test prototype to shoot the X-rite ColorChecker SG color test target at ISO 100 degrees, and then analyze the color, and we can get 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.

The following is a test picture:

▲ The picture shows the color saturation error test results of Canon SX30IS.

▲ The picture shows the color saturation error test results of Fuji HS 1 1.

▲ The picture shows the color saturation error test results of Oba SP-800UZ.

▲ The picture shows the color saturation error test result of Panasonic FZ40.

▲ The picture shows the color saturation error test results of Kodak Z98 1.

From the test results of color saturation, it can be seen that each product continues the characteristics of its own brand in color saturation performance, especially the red color saturation is higher, among which Canon SX30IS has the best color saturation restoration degree, and Kodak Z98 1 has a stronger overall color performance.

White balance error test results of various products

Looking at the white balance error performance of all products, the white balance of all five products is warm, among which Panasonic FZ40 is the most accurate, and Kodak z98 1 has a relatively large white balance error.

The wide-angle end of Obakodak is distorted.

Next, focus on the lens distortion test of the wide-angle end and telephoto end of the five products. Fuji HS 1 1 with a 24mm wide-angle lens, the barrel distortion test data at the wide-angle end is -0. 153%, which is almost unrecognizable to the naked eye and performs best. Kodak Z98 1 has the most obvious wide-angle distortion, and its barrel distortion test data is -3.76%. At the same time, the distortion of Oba SP-800UZ at the wide-angle end is also recognizable to the naked eye. Then, look at the performance of various products at the telephoto end. From the comparison chart of test results, it can be seen that the distortion control ability of the five products at the telephoto end is excellent, and almost all the distortions are generated.

Summarize the image quality comparison of Canon SX30IS, Fuji HS 1 1, Oba SP-800UZ, Panasonic FZ40, Kodak Z98 1, and compare them in terms of clarity, noise control ability, color saturation, white balance and distortion control ability. Based on the overall performance of the five products, Panasonic FZ40 won the title of image quality comparison by using high-quality Leica lens in sharpness and other test comparison results. Fuji HS 1 1 won the noise control and distortion control tests, but failed because of its unsatisfactory sharpness. Of course, the other three products also have their own brightness, and the zoom multiples of these five products are also different. I just hope that by comparing the image quality of these five products, I can provide some reference for users and make more suitable choices.
