Documentary camera selection

6D is entry level, and 70D is mid-range and half width. The positioning is different. Of course, the picture quality of 6D is better, and the focusing system of 70 d is stronger. These two cameras can be said to have their own advantages. Let's talk about the advantages of Canon 70D. First of all, it has a better focusing system, a shutter speed as high as 1/8000 and a more advanced video shooting system. The advantage of Canon 6D is the better image quality brought by its Quan Huafu-sized sensor, so if you are not particularly concerned about whether the camera is Quan Huafu, you can consider Canon 70D. Otherwise, I think Canon 6D with larger sensor size is more worth choosing.

The difference between Quan Huafu and APS-C

First of all, Quan Huafu's image sensor is larger than APS-C, and the resolution of 6D is better than that of 70D.

Secondly, talk about high sensitivity. In the case of insufficient light, the exposure time will be extended, especially at night. Sometimes in order to achieve the highest image quality at low sensitivity, you have to use a tripod, but when is there no tripod? Is it necessary to increase the sensitivity to reduce the exposure time? The digital image processors of 6D and 70D are the same, but the image sensor of 6D has a larger area. Under the same high sensitivity condition, the noise suppression ability of 6D is stronger than that of 70D.

Thirdly, focusing, the focusing of 6D in low brightness is even stronger than that of 1DX and 5D3, and it can be autofocused at -3EV. Fourth, talk about the number of autofocus points. The 70D is a model focusing on high-speed continuous shooting and tracking and capturing moving objects (19 autofocus point), while the 6D is a model focusing on taking Quan Huafu resolution photos. We can't judge the performance level of the camera only by the number of autofocus points, but mainly consider what kind of subject to shoot.

In addition, if you want to practice photography, SLR takes a long time, basically focusing on a single point, and mainly focusing on the central point, which is not very helpful for learning photography, and is suitable for shooting moving objects with a large number of focuses. And personally, I think that 7D is more professional and cost-effective than 70D (if the landlord needs high-speed continuous shooting). The only thing that 70D is better than 6D may be video shooting. After all, 70D came out late and the technology was new.

Finally, talk about the price. Because the landlord already has 24- 105, it is enough to buy a 6D stand-alone camera. An APS-C camera with this lens can't reflect the full value of the lens. At present, the price of 6D single camera is around 9900, which is already very low. 6D is more valuable than 70D, so the price will not fluctuate too much in three years. In addition to taking portraits, you can also shoot humanities documentaries. Special ones are 85 and 135. The focal length of 50 is different from that of 24- 105. Setting the Jiao Da aperture helps to blur the portrait background. As for the 6D shutter, the fastest shutter time is only 1/4000 seconds, except in extreme environment, which requires a faster shutter speed. This speed is enough in daily situations, and it is also completely enough for the landlord not to buy 50 1.2 and 85 1.2. If you buy 1.2 large aperture focusing, it is better to change the fuselage to 5D3, but.
