What are the advantages of SLR camera Canon 70d over 60? I just bought a second-hand one from Fenyi, and I'm playing by myself!

Although Canon 70D still uses APS-C format sensor, it has some very interesting technologies, including CMOS focusing mentioned at the beginning, which is unique among all Canon camera products at present. In addition, the pixel of this sensor has also increased to 20.2 million, which is higher than the18 million pixel of Canon 60D.

Image processing engine

First of all, we saw that consumer models including PowerShot SX280 and PowerShot SX270 began to be equipped with the latest DIGIC 6 processor, but 70D chose the same DIGIC 5+ processor as Quan Huafu SLR 6D. Even so, it is much more advanced than DIGIC 4 of Canon 60D to compensate for the increase of pixels per inch, but the sensor size has not changed, which may affect the image quality.

ISO sensitivity

The improvement of image sensor naturally means the improvement of ISO sensitivity. At present, Canon 70D can achieve the original sensitivity in the range of ISO 100- 12800, and can be extended to ISO 25600；. . The 60th day is ISO 100-6400, extending to ISO 12800. Theoretically, Canon 70D can achieve better night shooting effect through high ISO and multiple noise reduction functions, but this has yet to be tested in practice.

Continuous shooting speed

The brand-new image processor engine has also brought faster continuous shooting speed to Canon 70D, from 5.3fps of 60D to 7fps, which is still not as good as 8fps of high-end product 7D.

viewfinder

Canon 60D and 70D both adopt pentaprism optical viewfinder, the difference lies in the coverage of the field of view, the former is only 96%, and the latter is increased to 98%, which can obtain a more complete framing effect.

Screen design

On the screen, although the Canon 70D still continues the 60D 3-inch/kloc-0.0 million pixel screen, it adds touch function. This is a capacitive touch screen, which can realize the operation effect of the process, and can also change the autofocus point of the camera through the touch screen during real scene.

Complementary metal oxide semiconductor sensor

Canon 60D adopts 9-point cross focusing system, and 70D is upgraded to 19-point full cross focusing, but the difference is that the latter adds new focusing function. Canon 70D designed two photodiodes on each pixel of CMOS sensor, thus obtaining a diode with 40.3 million pixels. When using live view function to take photos or shoot videos, these considerable diodes can independently read data and realize the phase detection function, which will greatly improve the speed and accuracy of autofocus.

WIFI connection

WIFI wireless connection is a very popular new function in the camera industry. It can not only realize the picture transmission between camera and computer, tablet and smart phone, but also support camera and smart phone/tablet to take photos remotely through special App, and directly connect to WIFI printer to print photos, or upload photos to Canon Web server or watch photos through DLAN connected TV.
