Canon presented yesterday the new and acclaimed EOS 70D, an APS-C camera dedicated to camera lovers. This body substitutes 60D in the Canon range, positioning itself between the Rebel T5i and the 7D. While the first is a fairly recent entry-level model, it is slightly changed with respect to the previous T4i and T3i. The 7D is an older model, with 4 years of age. However it belongs to a much superior category. Now it still is one of the best APS-C on the market, incredibly popular amateurs and professional, both in fields of photo and video. It has become even more attractive now that great deals can be found when buying it used. As long as the 7D model is not updated, which it’s presumed to be done by the end of 2013 and beginning of 2014, the 70D will have more space for action and will be better able to appeal to the taste of experienced amateurs with some new important features offered that the 60D doesn’t have. These are: Weather sealed body, better performance of AF module, higher ISO extension, faster burst, new menu with intuitive touch screen, and the revolutionary sensor with Dual Pixel CMOS AF.
And the following, we will have a comparison between 70D vs 7D：
Advantage of 70D
Canon currently has 18MP sensors in the 7D, 60D, T4i, T3i and T2i. Finaly, The 70d offers 20.2MP resolution, The EOS 70D’s best attribute is undeniably its distinctive dual pixel sensor that could possibly improve the live view that it once had and video speed by as much as five times. And that was the best feature of the 70D. The 70d has 20.2 MP resolutions, but it utilizes 2 photodiodes for each individual pixel. They face left and right so that they have on chip phase detection. This will greatly improve the autofocus for both live view and movie recording. For instance, Canon states that the EOS 70D has the ability to focus in on a face when the person is going from one place to the other, even when you are trying to film with a fast lens at big apertures.
The Dual Pixel CMOS AF is based on based detection sensors, and it is designed to provide a smooth focus and video of high performance. It also has a fast autofocus when shooting pictures in Live View mode. It is ideal for the development of professional looking “pull-focus” effects, for keeping a subject movement towards the camera always in focus, while keeping the background blurred.
EOS Movie allows the user to capture video with a shallow depth of field, but a certain level of skill is necessary to obtain an accurate focus. The Dual Pixel CMOS AF has been developed to make it easier to shoot video and control the focus capability when the subject is moving across the frame. With Dual Pixel CMOS AF, the management and control of the focus in video mode is faster and easier than ever. As it ensures that it verifies there are no errors in the in the focusing while the action takes places and the subjects are moving within the frame.
Dual Pixel CMOS AF comes in handy when photos are taken in Live View mode (it is framed with the LCD display): fast autofocus, similar to speeds available when using the viewfinder.
The new 70D features the DIGIC 5+ processor while the 7D features the old DIGIC 4 processor. When it comes to speed, the DIGIC 5+ has speed that is approximately three times as fast as DIGIC 5, and more than 17 times as fast as the DIGIC4. Based upon quality, the processor can calculate more via pixel to pixel. This can be done right then. This means that you will have more chances to look at each picture and make changes before it goes to the memory card
This camera has extra power to process, which means that it has a frame rate that is always shooting(burst) and also can do better at correcting noise via signal processing. Where the EOS 60D had a burst mode speed of 5.3 images a second, this is boosted up to 7fps in the 70D. When it comes to data throughput, the 70D may be better, but its continuous shooting speed is not as fast because it has a higher quantity of sensor MP.
When it comes to the RAW image buffer, the 7D is better because it has a V2 firmware that was added on last year. It expands the last 15 RAW images to 25 RAW images. The 16 images that the 70D has is somewhat okay, but the 7D will be much better for those who want to shoot plenty of sports photos and have to have RAW. Keep in mind that a majority of professional sports photographers with deadlines use JPEG.
Like T4i and t5i, Touch Screen is be used in the new 70d，this is a great advantage the 70d offiers over the 7D is that the touchscreen should help make setup easier. The 70d has 1,040k dots resolution screen, better than the 7d’s 920k dots
The EOS 70D is the second of Canon’s SLRs that have built in Wi-Fi. This is not surprising because it is almost the same system that the EOS 6D has. It has a good range of features and unique setup flexibility. You have connection to other devices by utilizing a current Wi Fi network or you can connect to it directly. Also, it saves up to 3 setup profiles for fast recall. For instance, one can connect directly to your phone for your use out in the field. And you can use the other for your tablet and another one that will connect to your computer via your Wi Fi at home. One thing that the 70D has that the 6D doesn’t is that it has a touch screen, which makes setup much simpler.
The Wi-Fi for 70D has the following features:
- It transfers pictures between Canon cameras that have Wi-Fi
- It connects to either your Smartphone or tablet by using EOS remote
- It has a remote control from your personal computer via EOS utility
- It can print from a printer that has Wi-Fi capability.
- It can upload to any web service by using Canon iMage Gateway
- It views pictures on devices that have DLNA.
When you use the free EOS Remote app and connect the 70D to your Smartphone or tablet, you can utilize it as a remote control. This gives you the power to set the focus point that you want, have a continuous live view and control things such as the shutter speed, aperture, ISO and exposure compensation. You can look at your pictures and rate them. You can also transfer them to decreased resolution so that you can look at them and share them with others.
Better AF in live view :
On chip phase detection has been around for a while. It was first introduced in 2010 with a well known Fujifilm F300EXR model. It has been used time and time again by other manufacturers since its introduction. It has undeniably had the most success with the mirrorless cameras at Nikon. However, even up until now it does not use that many pixels on the sensor. It has been limited and has only covered a limited section of the frame. It used to struggle when the light dropped less than regular daytime light levels. Canon claims that it has a Dual Pixel AF system that is different. It supposedly operates over an area eighty percent of the frame in terms of height and width. It can also work in light areas that are as low as 0 EV and with apertures that are as low as F11. If this is true, then this might be the best option for live view autofocus system that is offered on any kind of camera.
We have already mentioned the capability of shooting video. Canon EOS 70D enables shooting Full HD video with frames between 30 – 24 fps, or 50 – 60 at 720p, The new camera from canon is able to capture sound, by using an external microphone and a range of compression options for post-editing and sharing. Because of the Dual Pixel CMOS AF, the Movie Servo AF mode can track objects as they move around. It can even do it if the images are messed up or blurry. This makes sure that they are never out of focus. On the flip side, you can choose various focus section areas up to 80 percent of the frame by just a tap on the touch screen. This can be done even at the time of recording. This will ensure that the movie remains clear as a bell and if the object moves or you change the shot.
HDR(high dynamic range) and Creative Modes：
If you like how the HDR looks but you do not like to spend a lot of time on the computer, then the 70D has a built in feature that you will really like. The EOS 70D has a variety of creative modalities. The HDR in-camera function eliminates the difficulties of shooting in troubling situations with high contrasts, blending three exposures in one to capture more details in the areas whether in light or shadow. With Multiple Exposure mode, the photographer can shoot and combine up to nine exposures into a single image, or use a range of creative filters to change instantaneously the style and appearance of the shooting. The integrated Speedlight wireless transmitter provides in-room and wireless control of multiple Canon Speedlite EX units.
The 70d has an ISO range of 100-12,800 (expandable to 25,600) for shooting in lower-light conditions.
Advantage of 7D
The 7D is the first EOS camera with a 100 percent coverage and 1.0x magnification viewfinder specification. which can offer the photographer the exact perspective of how it will be fixed in the final image.
Better shooting speed:
The 70D can do 7fps in burst mode and the 7D can do 8fps, which is a difference of 1fps. Will this really be noticed? If you are not a professional photographer, then you probably won’t. This is a true statement because professional sports shots can be taken from a lot of different cameras from ranges of 3.5fps to 11fps. The 5D MKIII can shoot 6fps and it does not have a hard time shooting great sports pictures. So both cameras can be used to get great sports pictures. You could also get wonderful wildlife pictures too.
For now the 70D vS 7D is a close battle but for the most part my recommendation is to go with the 70D. In terms of AF and speed it’s on a par with the 7D. It offers a slightly larger image and performs better at high ISO. Really the only advantage that the 7D has is 1FPS faster shooting speed, magnesium shell and a viewfinder that covers 100% of the image. Whilst I do love a 100% viewfinder, the 70D is 98% and likely this will not affect your image making abilities.
If you really really beat your cameras up then the 7D might still be a better proposition but otherwise the 70D has the edge due mainly to the new AF mode for video shooting and also the handy swivel screen.
User Review is important:
Besides the specs difference, the real reivews from users is very improtant for us to choose a camera! I suggest you read the User reviews about the 70D or 7D on Amazon:
You can buy these two cameras on amazon at a cheap price.
