Canon 70D (single machine)

   　 Canon EOS   70D The overall design style of EOS continues 60D Steady and professional line. The continuous surface fully maintains the hand feeling when holding, and the hard edges and corners also make camera It is full of "manliness". Canon EOS  70D With the new body coating, the frosted surface not only feels fine, but also can effectively prevent the generation of fingerprints. In terms of size and weight, the new EOS 70D is slightly smaller than the EOS 60D, and the weight is completely the same.

The right side of the screen is the control area of the camera. The design here is different from that of the EOS 60D. The main difference is reflected in the video button. When the START/STOP key of the EOS 70D is pressed, the camera will switch to the real-time viewfinder mode, and moving this key can quickly switch to the video mode, which is similar to the full frame SLR 5D3 and 6D bring into correspondence with. The video mode of the EOS 60D is on the mode dial, and the operation efficiency is not as high as that of the EOS 70D.  

After looking at the overall appearance, let's take a look Canon EOS   70D Details and holding experience. from camera From the top of, 70D And 60D The main difference is the mode dial and the focus area selection key. The 70D mode dial only retains common gears such as P, Av, TV, M, B, C and creative scenes, while many scene modes and video keys have been canceled before.

Canon EOS 70D interface is on the side of the fuselage

Several common data interfaces Microphone , shutter cable and HDMI are essential, and all interfaces are set on the left side of the fuselage.

What I got was a set of products equipped with EF-S 18-135 IS STM lens, and the outer packaging continued Canon's previous style.

As soon as the EOS 70D fuselage is taken out, the first impression is that there is no change in appearance with the EOS 60D, but the workmanship and feel of the whole machine are much better. After playing around, we found that the EOS 70D is different from the EOS 60D in some details. Here are some minor differences between the two machines.

Canon used the newly designed 2020 megapixel APS-C CMOS sensor on the EOS 70D, which is no longer the 18 megapixel sensor that has used several generations of products.

Canon EOS 70D uses a new 20.2 million APS-C frame CMOS image sensor

This CMOS is equipped with the Dual Pixel CMOS AF technology previously introduced, which realizes the innovative auto focusing function of phase difference detection. At the same time, its single pixel area is about 4.1 × 4.1 μ m. In the semiconductor production process, Canon improved the fine processing technology, and at the same time, it configured microlenses on the surface of each pixel to improve the focusing rate, shorten the distance between the photodiode and improve the photoelectric conversion efficiency of the photodiode. In addition, the transistor in the pixel has been improved to achieve high sensitivity, low noise and wide dynamic range while exceeding 20 million pixels.

In terms of image processor, Canon EOS 70D has upgraded to a new DIGIC 5+image processor, which can quickly and properly process the huge amount of information of about 20.2 million effective pixels from CMOS image sensors.  

DIGIC 5+image processor

High speed processing circuit brought by 8-channel high-speed reading  

The DIGIC 5+image processor has greatly improved the processing speed. Its processing performance is about 17 times that of DIGIC 4 and 3 times that of DIGIC 5. DIGIC 5+is responsible for multiple processing tasks inside the camera, including high-speed focusing of Dual Pixel CMOS AF (full pixel dual core CMOS AF), image generation, noise reduction processing, RAW imaging in the camera, high-speed continuous shooting of up to 7 pictures/s, real-time compensation for the inevitable multiple color aberrations generated by different lenses and full HD short film shooting, which enables the EOS 70D to have both high image quality and high performance.

  What's the Difference Canon EOS 70D Appearance (I)

First, let's still take a look Canon Appearance of EOS 70D. The Canon EOS 70D received is already a commercial retail version of EF-S 18-135 IS STM package. In addition, the EF-S 18-200 IS package is also available in the market, which is also very practical.

We note that this lens used in Canon EOS 70D EF-S 18-135 IS STM package is also a newly updated APS-C lens covering the basic focal section, especially supporting IS lens anti shake and STM mute motor. Anti shake, mute and coverage are equivalent to about 24-200 focus segments, which is sufficient for shooting various subjects, and is very suitable for a lens of ordinary users.

Canon EOS 70D package includes body, lens, hood, shoulder belt, instruction manual, battery charger, instruction CD, data cable, etc. In the manual, many practical materials are provided, including Wi Fi function description, lens guide, etc. Users are advised to read the instructions carefully before using the camera again. At least before writing this article, the author has read the instructions twice, including some functions that are easy to miss.

Canon EOS 70D adopts plastic body for dust prevention and waterproof The performance is equivalent to the early 35mm film SLR EOS-1N

Some people may complain about why Canon EOS 70D still uses plastic body, but in my opinion, it does not seem too important. It may be due to cost control or fuselage positioning. Although the aircraft does not use an all metal fuselage, it still provides a certain dust-proof and waterproof performance, which is disclosed to be equivalent to the early 35mm film SLR EOS-1N. The handle feels very good, and the rubber is very soft. Of course, here we have to mention one of the competing products Nikon D7100 , relatively speaking, Nikon At least the design of metal fuselage will win the favor of some users.

Canon EOS 70D adopts three-way flip touch screen Keys follow the classic layout

We noticed that the Canon EOS 70D still uses a three-way flip screen. The 3-inch EOS 70D does not have much improvement at 1.04 million points, but it adds the touch function, which allows the touch to release the shutter and select the focus.

Canon EOS 70D side view

On the top of the fuselage, we noticed that the focus selection button has been added, which is similar to Canon EOS 5D The design of Mark III is similar. In addition to single point free focus and global focus, the selection of regional focus is added, which is somewhat similar to Sony 。

Canon's fuselage design in recent years has tended to be round, and the EOS 70D is no exception. Maybe some people like the tough shape like EOS 3, while others think that the rounder shape is acceptable. Let's have our own love for turnips and vegetables. The EOS 70D does not use a metal body, but it still has a certain dust-proof and water repellent function. However, it is a plastic body after all, so its reliability in extreme environments is questionable. Some users mentioned that they hope Canon EOS 70D can adopt Nikon D7100 If the top magnesium alloy structure is really like that, I believe many users will be very satisfied.

The battery adopts the general LP-E6 model with a battery capacity of 1800mAh

Canon EOS 70D battery is the same as the previous generation and Canon EOS 6D 、 5D Mark III With the same LP-E6 battery, more than 920 photos can be taken with a single charge, and the endurance performance is excellent. Of course, according to the official introduction, if the real-time shooting mode is used for shooting, then the endurance shooting will be more than 210. It can be seen that although the real-time viewfinder is very convenient, it still consumes a lot of power compared with the OVF optical viewfinder.

  Detail Adjustment Canon EOS 70D Appearance (II)

Canon The EOS 70D is equipped with a full pixel dual core CMOS structure, so the focusing speed is significantly improved during real-time shooting. On the scene of the product launch, we learned from interviews with Canon R&D technicians that the lens equipped with the STM motor will bring a more silent shooting experience.

According to the author's own test, if a lens like a small spittoon without a mute motor is used for automatic AF, the sound of the motor is still loud. If you want to shoot high-definition video, it is recommended to choose a lens with STM and USM motors.

Canon EOS 70D microphone, shutter cable, HDMI output and USB interface

The sides of Canon EOS 70D are microphone, shutter cable, HDMI output and USB 2.0 interface, and it also supports external monitor via HDMI. At the top, we can see that there are several holes in the speaker part of the machine.

Canon EOS 70D mode turntable

The mode dial part provides the PASM common mode, SCN scene mode, C custom mode, CA intelligent mode, A Plus intelligent automatic function, and the courtesy mode of flashing off. The mode turntable lock is provided. To adjust the mode turntable, the user needs to press the middle lock key and then rotate it.

Canon EOS 70D top flash

Canon EOS 70D uses built-in flash and hot shoe. The hot shoe supports ETTL flash, and the built-in flash index is about 12 (ISO 100, in meters). It also supports flash master control. The flash part is very prominent when the flash is ejected, which also takes into account the reduction of the shadow of the fuselage when using a longer lens.

The optical viewfinder adopted by Canon EOS 70D supports 98% field of view rate, and the OVF supports display of exposure value, level, etc. And EOS 6D Same as the single card slot design Nikon D7100 The double card slot is inferior, but it also conforms to Canon's consistent design idea.
