Canon 70D Camera Review Detailed

Canon EOS 70D Camera

There is a lot to like about the eagerly-awaited alternative to the Canon 70D. It comes with a fully optimized autofocus system, Live View / video without the need for special lenses; a more streamlined body design with an articulating touch screen; and Wi-Fi support. And with only a few exceptions, I like the 70D and love to shoot with it; it’s fast and snappy and will still be one of the best Canon cameras available today.

Pros: The new sensor of the Canon EOS 70D delivers excellent autofocus performance, and the camera itself is quite fast. Its design is streamlined and features well tailored to the target market.

Cons: The picture quality isn’t too impressive for this price point, and certain aspects of the design – notably a single card slot, hard-to-control multi-controls, and conflict mode resolution movie / Wi-Fi – annoying.

Bottom: Line A great camera in general, but one that doesn’t win the best class award for image quality.

Xi Pa Chao will review the Canon 70D in detail in the article below!

1. Design

I really like the camera’s design, although there are a few things I wish were a bit different. Overall, it’s a slightly more streamlined composition than the 60D, so overall it’s comfortable to hold and shoot, even one-handed.

On the upper left is Canon’s typical current mode dial with the center lock button. It features the usual manual, semi-formal, and automatic modes, along with a single custom install slot. On the upper right of the LCD screen is a series of direct access buttons for metering, ISO sensitivity, drive mode and autofocus mode (single, AI Servo and AI Focus), along with the top dial and second AF area selection button. You cycle through your AF area options – single point, Zone (center 9 points or 4 points at top, bottom, left or right) or automatically 19 points – by pressing the button repeatedly, Then select the point or point button using the Quick Return control dial.

The back offers a typical Canon thumb-operated Live View / Movie switch with the record button; AF-On, exposure lock and second AF area selection buttons are arranged above the thumb rest; Quick control panel and review buttons next to LCD display; and the multi-controller navigation controller is inserted in the quick control dial around the Set button. It has a dedicated lock switch; you can choose to apply it to main dials, speed dials, multi-controls or any combination. On the front near the bottom of the lens mount is a small, reprogrammable depth-of-field button. The viewfinder is large and bright enough for the preview to use.

Canon’s articulated touch screen is still a favorite of mine for video recording, and the 70D keeps the same look and feel as the T5i. It is responsive and has an intelligent user interface that includes the usual capabilities, like touch focus, that streamlines Live View shooting. You can see the screen quite well under direct sunlight. You don’t have to use it if you don’t want to, although operations like selecting the ISO sensitivity will be much faster when you can select directly instead of having to cycle through them. Overall, I find Canon’s interface simple and easy to use.

2. Feature

The Wi-Fi implementation is identical to that of the Canon EOS 6D, and not bad for remote shooting with the EOS Remote app, which now allows you to change shutter speed and aperture, ISO sensitivity and exposure compensation. Connection configuration is not easy and difficult; The camera acts as the access point, which you then set as the device’s Wi-Fi connection, then launch the app. However, as with many of these cameras, it doesn’t always connect to the phone.

Canon 70D Camera Features

You can also connect the camera to a computer wirelessly using Canon EOS Utility, but only through an access point, not peer; that makes it useless for a subset of instances. Setting it up was a bit more complicated than I expected (or more than I expected in 2013) and the camera did not consistently see my work network.

The Canon 70D offers a fairly wide set of video-specific features, although like most of the company’s dSLRs, it doesn’t seem to be able to output clean HDMI for external recording (though I wouldn’t be surprised. if that possibility finally appeared in the Magic Lantern hack.) Like many dSLRs that Canon is about to release, there’s nothing else of note in the 70D’s feature set; a streamlined but no-frills photographer-friendly set of shooting options such as time lapse / interval, multiple card slots or multiple custom installation slots.

3. Image quality

Image quality didn’t change significantly between my pre-production and final tests, but in my opinion it does. It’s good now. Not outstanding for money, but not bad either. However, it’s simply not as good as the Nikon D7000. Yes, it’s still an improvement over the 60D, but not very big – I don’t think you can even stop usability entirely, and any advantages seem to come from the slight increase. resolution. It’s slightly better than the Rebel T5i across the entire sensitivity range, though you really have to look at them closely.

I am starting to think that Canon actually pushed the contrast up to its Default Picture Style to increase the sharpness of the image, because when you look closely at the details, they appear very soft. Even so, you will lose a lot of shadows and highlighting details if you leave the Picture Style on Auto. The dynamic range doesn’t seem particularly wide, not having a lot of outstanding data that can be recovered in raw files and shadows that are hard to produce without causing noise. However, the new sensor appears to have better noise patterns at higher ISO sensitivities than previous sensors.

Image quality

JPEG photos look OK up to about ISO 1600; Also it depends on the scene content. I can sometimes produce sharper images at ISO 1600 by shooting raw, but not always.

Thankfully, video from the production unit looks better than the pre-production unit, although it has the same general softness as stills, combined by a relatively low HD resolution. It shows edge artifacts, jagged, moire, and crawl – this, as is often the case, gets worse as ISO sensitivity increases. It looks a bit better than the T5i, though it’s not that obvious and most casual users probably won’t see a big difference. Low-light video has nice tonal tones and reasonable dynamic range, but still has a lot of color noise.

4. Efficiency

Except for the speed of focus in dim light, the 70D delivers excellent performance. (Looking back at my pre-production report, I think I misjudged that result as 0.3 seconds instead of 0.7 seconds.) It turned on, focused, and shot for about 0.4 seconds, no Nikon must be fast, but overall fast enough and much better than Canons. Time to focus, expose and shoot in good light will run as fast as 0.2 seconds and in dim light for just 0.8 seconds. Two consecutive JPEG or raw images also ran for about 0.2 seconds, up to only half a second when the flash was turned on. In Live View mode, up to 1.5 seconds.

Continuous shooting works really quickly for this class, with a buffer deep enough to make speed useful. JPEG runs through 30 photos at 7.1fps; Raw shooting has dropped to about 2.5 fps after about 17 shots during testing, but in field testing I maintained raw 9-shot + JPEG bursts with Servo AI focus a reasonable way. That’s pretty good for a numerical model. (Use a SanDisk Extreme Pro 95MBps SD card.)


The new Dual Pixel CMOS AF (DPA) autofocus system is a definite update over many previous Canon models, both from a performance and functionality perspective. Normally, a photodiode – an element on a sensor that collects light and converts it into an electrical signal that carries image information – transmits only image data. The DPA divides the two photodiodes into two, comparing the signals from each half using a phase detection algorithm for autofocus.

There are several theoretical advantages of the new architecture. First, it is likely to be faster, mainly because it brings the lens directly to the focus position; it doesn’t have to repeat in the fine-tuning position like contrast AF, and it can more quickly determine focus as it measures the sensor instead of having to go through a separate phase-detect sensor cycle. Second, it takes up about 80 percent of the frame (as is the implementation of the SL1), which improves off-center focusing performance. And third, the lens doesn’t need to be hunted, which makes operations like focusing smoother when recording video.

In fact, the system provides; Working in Live View is relatively seamless. For stills, it typically locks on quickly and accurately, regardless of the AF area mode, and Live View is fast – about 0.6 seconds to focus and shoot in good lighting conditions. This is the first dSLR I’ve used where Live View is actually usable for stills. In dim conditions, it’s not nearly as great – 1.5 seconds to focus and shoot. While that’s not optimal for stills, it’s great for video recording in low light, where you want the focus to flick rather than snap. It racks really well with touch focus.


I want to rate the camera’s image quality at 7.5; it’s great, but overall not quite as good as the D7100, everything is considered. Unfortunately, since the rest of the package – the excellent autofocus system, a neat shooting design, and the right feature set for the price – add to a camera I really like.

Thank you for watching the review of the Canon 70d camera in my tech column. Hope the information I shared will be useful to you.
