Canon IXUS860 noise issues

ISO noise comparison screenshot 2.

The Canon 860 is has a sensitivity range from 80 to 1600, while the Sony T200 has a sensitivity of 80 to 3200. As you can see from the actual screenshots, the images are relatively clean in the ISO 80-400 sensitivity, with almost no interfering noise, but sharpness is noticeably higher on the Canon 860 IS than on the Sony T200, which produces a more pronounced fogging effect at the edges of the font.

At ISO 800, the Sony T200 controls noise levels in the bright parts of the screen a little better, but it's still not as sharp as the Canon 860 IS.

Transitioning from ISO 800 to ISO 1600, the Sony T200's noise is more naturally excessive, with noise being handled to a certain extent. On the other hand, the Canon 860 IS's noise is noticeably noticeable, and the image is more fragmented. Since the Canon 860 IS does not have ISO 3200 sensitivity, comparability does not exist.

However, looking at the Sony T200's noise level at ISO 3200, you can see that the noise is well controlled in bright images, but the noise in the shadows is more noticeable. However, in general, ISO 3200 is not very practical.

As you can see from the above comparison, the Canon 860 IS has better sharpness than the Sony T200 in low sensitivity conditions, and the resulting image is relatively pure and clear. At high sensitivity, the Sony T200 has a slight edge, and the in-camera noise reduction is better.

You see that 860 has more dry points than 530 because the 530 screen has lower pixels, and the pixels are larger than the 860 screen pixels. So it feels like 530 is less dry than 860. Actually, it's the same. It's just that the 230,000-pixel screen restoration ability of 860 is too strong.

Dry spots are present with every camera. It can't be avoided. The darker the ambient light, the more dry spots. Includes Canon's top-of-the-line 1DS Mark IIIIt's just that 1DS is a lot less than a home machine.

Flash issues. Remember that Canon's machine flash can be adjusted to slow and simultaneous flashing. This will not cause local over-brightness problems. I forgot where I set it exactly. Have time to take a look at it for you.

Set up a tripod with low ISO, slow shutter speed, large aperture.

The first time you see the Canon Ixus 860 IS, you will have a familiar intimacy. In terms of exterior design, the 860 IS still maintains the style of its predecessor, the IXUS 850 IS, with an asymmetrical design on both sides, and the overall look is very beautiful. The fuselage is made of sturdy stainless steel, and the surface has been treated with a special process, which is both smooth and bright.

The IXUS 860 IS has changed the sterling silver and white design of its predecessor 850 products, and adopts a two-tone combination of silver and black, which is full of fashion and adds some sense of stability. The thickness of the IXUS 860 IS is that it is easy to carry.

The Canon Ixus 860 IS features a 1-inch, 8-million-pixel CCD sensor with a maximum resolution of 3,264 to 2,448 pixels** and can be printed in an A3 format. In terms of lens, a double optical zoom lens is used, and the actual equivalent focal length is 28 105mm, the maximum aperture, and the minimum focusing distance is 3cm. At the same time, the lens is still equipped with Canon's advanced IS optical image stabilizer, which can counteract some of the blurring caused by camera shake through the reverse displacement movement of the lens.

On the back of the Canon IXUS 860 IS body, it is equipped with a 230,000-pixel "Jingxuan" LCD, which has been re-upgraded by Canon this time, greatly improving the contrast and color reproduction area, which can effectively reduce the reflected light on the surface of the screen, and at the same time has stronger anti-wear and dust-proof performance. In addition, the IXUS 860 IS is equipped with Canon's third-generation DigiC III image engine, which is believed to bring better imaging results. In terms of buttons, it also provides one-button playback, which is very convenient.

The IXUS 860 IS has fewer upgrades than its predecessor, the LCD screen has been upgraded to 3 inches, and the third-generation DIGIC III graphics engine has been adopted. However, this full-performance flagship in the IXUS series is more than enough for home users who like card machines. At present, this ** of the ixus 860 is is very good, and friends who like it can pay more attention.
