As digital SLR cameras have evolved in recent years in terms of functionality and performance, shooting styles have become more diverse. An increasing number of users no longer rely exclusively on the viewfinder when shooting, but rather view the camera's LCD monitor when using the Live View function to capture still images and when shooting video. Each individual pixel the smallest structural unit capable of outputting an image signal on the CMOS sensor incorporates two independent photodiodes elements that transform light into electrical signals which output signals that can be used for both imaging and the phase-detection AF.
When using the EOS 70D Digital SLR camera's Live View function, the technology enables autofocusing with ease, flexibility, speed and accuracy similar to shooting through the viewfinder, enabling sharp focus to be obtained across a wide shooting area1 through phase-detection AF2 until final focus is achieved.
Compared with earlier generations of Canon's image-plane phase-detection AF3, Dual Pixel CMOS AF realizes shorter focusing times, outstanding tracking performance and smoother autofocusing during video shooting. Because the outstanding AF performance of Dual Pixel CMOS AF is made possible with models of EF lenses including many earlier models and models available outside of Japan , users can enjoy a wide range of photographic endeavors achievable with various lenses.
Recognizing great potential for the application of this technology across diverse product categories, Canon aims to promote its development efforts in the field of AF technology, targeting further advances to contribute to expanding the world of photographic expression. With conventional phase-detection AF, the light that enters through the photographic lens is divided into two images. The difference in the focus point position between the two images is measured on a dedicated AF sensor rather than the image sensor itself, enabling the camera to determine the direction and amount of lens adjustment required to obtain proper focus.
Because phase-detection AF enables fast focusing performance compared with contrast-detection AF, the technology is widely employed in digital SLR cameras, mainly for viewfinder shooting. Its large coverage area enables smooth and reliable image-plane phase-detection AF for both still images and video with no reliance on dedicated AF sensors or contrast-detection AF.
Contrast AF is an autofocus method employed in compact digital cameras and video camcorders, as well as conventional digital SLR cameras for Live View shooting. Because contrast is highest when an image is in proper focus, the camera analyzes the contrast information from the image on the image sensor, adjusting the lens until the maximum contrast value is reached.
While contrast AF offers high focusing accuracy, it tends to require more time compared with phase-detection AF because the focusing components of the lens must be driven during AF measurement to find the point of peak contrast. Sign up. To date, on-chip phase detect systems have provided but a handful of focus points scattered across the sensor's surface. With the Canon 70D, almost two-thirds of its surface area at the center of the frame can provide phase-detect AF, and not just at a handful of locations -- we're talking phase detect at every single pixel.
And unlike typical hybrid systems which use phase detect simply for a ballpark distance and direction to focus, then fine-tune with contrast-detect AF, the Canon 70D's on-chip phase detect is accurate enough that tuning with contrast detection isn't necessary. That is huge news for video capture, because it means no more hunting around the point of focus. With the AF bobble gone, full-time video becomes a much more exciting proposition, letting you quickly and smoothly guide your viewers' attention between subjects without distraction.
The new image sensor doesn't just drive the completely new autofocus system; in addition, its resolution has been increased slightly over the Canon 60D's.
Sensor size is unchanged, but Canon has increased the active imaging area of the sensor slightly, from This means that, although pixel pitch has been reduced, the difference isn't as great as you might otherwise expect. The net result is that, according to Canon, the 70D will produce noise levels that are roughly on par with the lower-res 60D for raw shooting. Meanwhile, the company says that JPEG shooters will see a "huge improvement" in image quality.
To back up that claim, the ISO sensitivity range has been expanded to encompass everything from ISO to 12, equivalents, with the ability to expand sensitivity as high as ISO 25, equivalent. Further in our review we'll see if the camera live up to these promises. The new image processor also yields a significant increase in burst shooting performance, which is now rated by Canon at a full seven frames per second.
Canon has gifted the EOS 70D with a new body that's just slightly smaller, while retaining the same side-swiveling LCD monitor, and packing in several new features. And supplementing the new on-chip phase detection system, there's also a new dedicated autofocus sensor, identical to that used in the EOS 7D.
As well as all of the hardware changes, Canon has made numerous tweaks to firmware as well. These include the ability to preview creative filter effects before shooting, a new 3x to 10x variable video zoom function, the same video snapshot feature seen in recent Rebel-series cameras, and a choice of both ALL-I and IPB compression schemes for video, along with optional time code. Although the Canon 70D looks a lot like its predecessor, it does feature a brand-new body design.
Let's take a look at what's stayed the same, and what's been changed. Seen from the front, the Canon 70D is a little less wide than is predecessor. Otherwise, though, the basic dimensions are pretty close to those of the 60D.
The arrangement of controls and features on the front of the camera is near-identical. The most significant difference is the absence of the small four-hole microphone port that, on the 60D, sat directly above the model number badge. Seen from above, the Canon 70D likewise retains an arrangement very much like that of the 60D.
As well as the two four-hole ports for the relocated microphone -- now stereo, and straddling the rear of the hot shoe -- there's a new button between the Shutter button and front dial. This new control is used to select between autofocus area modes. The number of positions on the Mode dial has also been slashed by a third, to just It's when you come to the rear of the camera that the changes are more significant.

In this evolution of sensors, you must consider the what and how of your photography and then decide the sensor. You've already decided on the glass L. Because you are considering the use of adapters you're not limited to Canon cameras.
You have so many things to consider; should you sell your arsenal and get into medium format digital. I was taught to buy the best glass I could afford and then get any POS camera with the money I had left.
Good luck on all your possibilities. I don't envy you. My Best, mulestick. I've read through the reviews here and elsewhere and I'm more taken by the 70d than 7D Mk II, especially considering the price difference. I picked up a Canon D on ebay a while back and it's been a nice, if limited entry experience into DSLR photography.
I like my Canon, yes I'm sure that they're a little behind Nikon in terms of absolute image quality at this level of camera but my biggest gripe with my current camera isn't the photos I've achieved with it but the poor viewfinder.
I really want to be able to manually focus at times and the poor viewfinder on the D, plus the total lack of any form of live view really makes manual shooting a nightmare. The Touchscreen really helps in portraits as you can preview if things are in focus quickly. And not to mention being a decent video camera. The 7D mark II on the other hand has better build, burst rate, buffer, Dual Card slots, focusing and viewfinder.
If you plan to do sports and wildlife in the future, this is the better option. The 6D or 5D Mark II is a good value for the money and the image quality is far more better than the 2 cameras you mentioned especially if you do a lot of low light shooting.
Go for the 70D. Goes well for fast shooting 7fps; good for sports and wildlife , manual lenses because of Live View magnification , high native ISO, responsive Touchscreen, and Dual Pixel AF, nice video capability especially when using STM lenses , but do invest on EF lenses if ever you want to upgrade to full frame later on.
I love everything I've read here except for one thing: without a headphone jack the camera is useless to me for video recording as we always need to mic a presenter or interviewee, therefore we absolutely must be able to monitor the quality of the incoming audio signal. It's a shame too as a certain warehouse box store has a great price on these now.
With a Boya SM80 stereo mic mounted on the camera and being fed into the mic socket, you have the headphone output on the Boya mic and they give you an earbud to listen with. It has a flexible mount and the audio quality is excellent. High pass filter, 10db pad and level control combined with 70D manual audio control gives very good results. I thought this initially but forget the headphone jack the audio on all DLSR's is not great.
You want a separate audio system which plugs in to the camera and then you can have full control and monitoring. What if the connector between the mic and the camera is faulty? You'd be hearing good audio coming out of the mic's headphone output, but you wouldn't know that you didn't actually record anything until you reviewed later.
Replaced my trusty Nikon D90 for the Canon D What a fantastic choice to make. The colours were simply beautifully such creamy bokah such naturally beautiful shots all way found. Daylight white balance. Why did I choose the Canon D70? I just love this camera the battery is great. I don't do cam just photo work. Oh 1 thing to mention is the burst rate??? Click click click away boy it's fast.
Just to add to my previous post, whilst I'll stick with the Sony a for now, I think the 70D looks like a camera I'd be happy to go for if i needed another camera.
I do astro photography and I'm sure that Canon is still the leader in that field of use within dSLR cameras If Canon reads this, this might be a good feedback for them to see why they lost a Canon dSLR user this time I've been using a sony a for half a year. I cannot agree with Tuan. It also amazed me when it could autofocus on some bright stars at night, and I did that from inside the house from my samsung S5 phone, whilst the camera was setup in the garden.
I guess something similar could be achieved with the 70D. If I was a professional photographer, I would probably stick with Canon, but as I'm not and mostly I would use the images on a computer screen, those 24MP images look just as good as any Canon image would Once again, my experience is based on the latest 7D, not 70D However, I feel most of the body made from plastic and I could easily break it to pieces.
When holding the 70D, you feel like holding a hi-tech device while the A brings to you 'PnS-like' feeling! Love the touch screen on 70D. And you know what: I saw a guy at camera store who tried to touch the A when navigating the menu all the time even he knew that it can not be! If you concern about the image quality between Canon vs. Sony, something like: 60 vs. I plan to buy a semi-pro camera with the kit lens in the next month or so.
I have a budget of about Rs. I am torn between mirrorless and Canon 70D. I am leaning towards the traditional DSLR more. Can someone please suggest which way I should go? I am hearing good things about the sony A but I will not be able to upgrade beyond that soon. Canon 70D or a mirrorless Camera. I owned both for a while and decided to keep the 70D. I feel more confident when holding DSLR cameras rather than mirorless ones.
Hey everyone, I've decided to upgrade from EOS D to 70D but reading all the reviews and everything is changing my mind. I'd appreciate it. It is best in the business. Having seeked expert advice before buying my first DSLR, I am happy that I could get the same opinion from all of them.
Hey there! I need your guys advice. My Sony NEX-7 with a got just stolen. I'm a travel photographer, means most of my pics cover landscapes, people, wildlife and sometimes sports. My preferences lay on a single lense with a big range, for that I was thinking about the Tamron in combination with the here discussed EOS 70D. Due to the fact of being in Costa Rica, my chances to buy the lense are pretty small. Any alternatives that are more comon?
Thanks a lot in advance. I used a Tamron mm as my work horse lens on one of my cameras just to avoid changing lens constantly. IQ was good. It's not too big, either. I only found means to do 3 Frames. Can somebody explain to me how to do more than 3 Frames or is it just a typo in the spec sheet? My intention behind buying this lens is just to make sure that I need not carry multiple lenses, and this should help me learn DSLR techniques. Please advise if this is a good combination.
I'd go for an STM Despite Canon's sensors are behind Sony's,I am seriously thinking about switching to Canon. Hi Steve70Dreinhardt If "the same issues as everyone else is reporting" means focusing problems, read this. I have solved the problem as following: In menu I put the focus point illumination on red squares in VF activate themselves, when focusing is ok.
Then I changed AF from one point focusing to 9 point focusing. Makeing this allowes the camera body to deside, which point are the best ones for focusing. Then I look at, that at least 3 points will be activated and if not, I make a new focusing untill it will happen.
This way the body can choose best points for focusing suitable amount light, contrast, details and colours. If I use one point focusing and choose the situation of the point by myself, it is maybe not good enough for the camera and then focusing is not ok. By this way I can shoot sharp pictures and misses are very few.
Hi All, I recently purchased the sigma 1. I have tried resetting the camera back to default but no difference was noted. I was advised by the shop to send the body and lens to Sigma in Australia where we are located for the lens to be calibrated to my camera body, however, my concern lies that the issue is a body issue not lens issue, can anyone confirm this?
I am about to go on a safari in Africa and was intending on taking a f2. I was thinking of purchasing this combination. Can you be a bit more specific about the problem please? I am aware that focusing wide open can be difficult, but in a lens of this focal length range I would normally focus manually anyhow.
Hello, when I shoot with my 70 D and then upload my footage to final cut, The start time of each shot is different. So for instance the 1st shot is from 0s to 12s well then the start time of 2nd shot will be 12s and so on and isn't zero It doest do this with my other cameras or the iPhone. You can reset the time code to 0 in the menu but it never does it automatically. I read the manual but i didn't understand anything.
Anybody has a clue? The start time of each shot should be zero! Timecode is needed to syncronize your movies between each other Either counting overall record time of your shots, or indicating where it was started.
So reset of timecode is needed, for example, if your starting new project. Use record time, it always starts with zero. I now see the purpose of a timecode! I thought you just sinked with the audio waves but i guess it can help with timecode too. But never mind it's okay ;.
I have a canon 70D, while taking photos a shaft of light appeared in the photo , I changed lens but it is still there. Can you tell me why this would happen? Hi Place this question on the Canon SLR forum and hopefully someone will give you a definitive answer! I have some thoughs but they may cloud the correct answer! Similar thing happened to a friends 70D.
If I remember correctly it was a horizontal bar would be lighter then the rest of the picture. He ended up having to get his shutter fixed due to a detached blade. Just a thought. How come nothing in the testing procedure is the same when you look up the "auto focus" sections of the 70D and the 7D mk II.
Would be interesting to see the 70D:s tests beeing performed on the 7D II, especially since the conventional AF of the 70D seems to be surprisingly inaccutate, and inconsistent. If the body and lens are matched perfectly, or you micro-adjust to match them, then the inconsistency goes away. It's just that this is the first DSLR with phase detect on the sensor that illustrates just how much better phase detect AF calculations on the sensor are.
Quick question: One of the features listed in this review is "silent shutter mode" which I found on the camera but it is not quiet at all. It's the loudest of any camera I've owned. Am I doing something incorrectly? I can't directly answer you question as I don't have a 70D, but I do have a 5D MkIII and the silent shutter modes on it are significantly quieter than the regular shutter modes.
And both silent and regular are much quieter than most of the Nikons I've heard. I take a lot of theater pics and I have found the silent mode to be great. It is generally inaudible from more than about 10' away if the room isn't dead quiet.
This review says, "In addition to capturing video at x at 30, 25, and 24fps, the 70D can also capture a still image, or multiple still images at full resolution Is there a way to create a still from a video frame after the fact so my video isn't all goofed up?
You can create any still from any video using your video editor program -- that would be the preferred method of doing so. Hi Allen, which camera do you feel performs the best in the 60D 70D price range? Not trying to debate was looking for your professional opinion. I'm interested in these two cameras: the 70D and the old 7D What would you guys recommend?
I usually do some landscape photography, portraits but in the near future I expect to learn about the timelapse technique. Video isn't really important for me so far. I would appreciate your opinions. Don't listen to the Nikon fanboy. For your needs, and given the age of the 7D, I'd go for the 70D.
It's updated in virtually all respects and represents a good value. Thank you guys for your advices I really appreciate it. I shoot sports. I'd like to know the best combination of eos 70d with the telephoto lenses.
