Experience Evaluation of Gankun Canon Powershot SX730 in Sleeve

IT 168 Evaluation Many photographers around me have the habit of taking telephoto cameras when traveling. This way, you can easily capture the distant scenery without adding too much load. What came to our IT 168 evaluation room this time is such a telephoto camera: Canon PowerShot SX730 HS, with 20.3 million pixels and 40x optical zoom.

Advantages:

1, 40 times zoom, 20.3 million pixels high available;

2, the body is small and portable, and it works well;

3, flip the screen to facilitate self-timer;

4, support Micro USB (charging treasure) charging.

Regret:

Touch operation is not supported.

Canon SX730 evaluation summary:

It is true that SX730 does not support RAW format, and the adjustable aperture range is better than nothing. But I think this price &; There seems to be no need for a fixed telephoto camera to have a rear computer and manual exposure, so I don't think these two points should be regarded as the shortcomings of SX730.

As far as a camera that can be easily put into your pocket and used with a long focal length of 960mm at critical moments is concerned, the Canon SX730 has really done a good job.

Comments on Canon Powershot SX730 fuselage with sleeves

Canon SX730 is a telephoto camera with 40x zoom, but the volume control is as small as a card camera.

▲ The front of Canon SX730 adopts periscope lens structure.

▲ Canon SX730 side

▲ The back of Canon SX730 is equipped with a 3-inch 920,000-pixel LCD screen, and the display effect is not bad.

▲ The top of the Canon SX730 is equipped with an on-off button, a zoom lever integrated shutter button, a mode dial and a video button. The design is simple and refreshing.

▲ The bottom is equipped with a tripod interface, next to the battery compartment.

▲ It's a pity that the screen of SX730 can't be touched, but fortunately, the button design and feel of the right-hand operation area are not bad.

▲ The fuselage interfaces on the right are mini HDMI and Micro USB respectively. Micro USB, also known as Android port, has a wide range of uses and supports USB charging. It must be praised!

▲ This small button on the left controls the turn-on of the flash, which is reasonable in design and not easy to touch by mistake.

▲ The flash also supports upward flashing, which is also well received.

▲ Compared with the previous generation SX720, SX730 has added a flip screen, which supports 180 degree flip, making self-timer very convenient.

▲24mm wide angle, 40 times optical zoom, the quality of the lens will be tested later ~

▲ The bottom battery compartment is integrated with SD card slot, saving the internal space of the fuselage.

▲ The battery capacity is not large, but since the body already supports USB charging, the power is naturally not a problem.

Canon SX730 fuselage comments:

Canon SX730 is light and compact, and its design is close to maturity. Perhaps the only regret is that it doesn't add a touch screen.

Analysis and measurement of Canon Powershot SX730

In telephoto cameras, the resolution of the lens is actually very important. After all, if you can't shoot clearly, it's no use focusing any longer. Then let's actually test the lens resolution performance of SX730.

We tested the resolution of SX730 by capturing a screenshot of 100% magnification. As for the camera on the tripod, turn off all internal optimization, ISO80, and take 100% of the screen center to enlarge the screenshot.

The first is the original picture of the 24mm wide-angle end:

Screen center roof position 100% enlarged screenshot.

It can be seen that the wide-angle performance of SX730 is good, and the eaves and antennas are angled. However, it makes sense to do a good job at the wide-angle end. After all, telephoto is more difficult.

Then we push directly to the longest end of this lens, which is equivalent to 960mm for shooting.

Original picture:

Roof position 100% enlarged screenshot:

It can be seen that even if the focal length of 960mm telephoto is pushed, the screws on the metal hinge can be clearly seen in the picture, which shows that SX730 has strong resolution.

At the same time, there is no visible dispersion in the picture, which makes the author satisfied.

Comments on the analytical performance of Canon SX730;

Unexpectedly, such a small machine can have such good analytical performance. At this point, it really caught me off guard. ......

Gankun Canon Powershot SX730 High Sensitivity Sleeve Measurement

The high sensitivity of the camera is directly related to the night scene and motion shooting ability of the camera. The better the high sensitivity of the camera, the higher the image quality in dark light, and the stronger the ability to capture moments.

Canon Powershot SX730 HS is equipped with a 20.3 megapixel 1/2.3 inch sensor. A sensor with a small negative image can obtain a longer equivalent focal length in a smaller volume. However, correspondingly, high-sensitivity performance will be relatively poor. Let's take a look at the high sensitivity availability of SX730.

The camera is placed on a tripod with an aperture of F8, so that the internal noise reduction optimization is all turned off and JPEG files are generated directly. Take a 100% enlarged screenshot of the position shown in the red box below each ISO file.

It can be seen that the image quality of Canon SX730 is the best in ISO80, and the details are obviously better than the following files. From ISO400, the details began to be obviously lost, and the straight edges in the picture began to become impetuous; Until ISO 1600 and ISO3200, the details in the picture have been mixed together, but fortunately, the red and green noises are well controlled, giving a good impression.

Canon SX730 High-Sense Image Quality Comments:

For a small negative camera, of course, we can't expect it to have as good high sensitivity as a SLR camera. However, it is good to enlarge the sensitivity of each gear to 100%, which is actually acceptable.
