CHAPTER 1

OVERVIEW

The EOS 70D is the latest in a line of digital cameras that stretches back to the 10D released in 2003. It also belongs to the EOS family of cameras that began with the EOS 650, a film camera launched in 1987.

The EOS 70D was announced on July 2nd 2013. It appears similar to its predecessor, the EOS 60D of 2010, but this is not necessarily a bad thing — Canon produces well thought out cameras with excellent ergonomics. If you're used to using Canon cameras, the EOS 70D will prove easy to become familiar with.

The major changes between the EOS 60D and the EOS 70D are internal, and start with the EOS 70D's newly developed 20.2 megapixel (MP) sensor. This may seem a small increase in resolution from the 18.1MP sensor of the EOS 60D, but the number of pixels isn't the only way a sensor should be judged. By using a revised DIGIC image processor (DIGIC 5+) the EOS 70D's sensor is able to extract more detail at higher ISO settings than the EOS 60D.

However, the real party piece of the EOS 70D's sensor is its Dual Pixel CMOS autofocus (AF) system. Canon has added phase-detection AF sensors onto the image sensor so that each pixel is able to gather light to create an image as well as determine focus distance. This means that AF is fast and smooth when using Live View and, perhaps more importantly, when shooting movies. Slow or non-existent AF during movie shooting has been a bugbear with previous Canon DSLRs, but the EOS 70D is arguably the first Canon video-enabled camera with AF that is as good as a top-flight camcorder. If you're interested in a camera with the capability of shooting high-quality stills as well as video, then the EOS 70D may well be the model for you.

CHAPTER 2

FUNCTIONS

In many ways the EOS 70D is a "Frankencamera," taking features from many of Canon's current cameras. However, with a new AF system it also has a (so far) unique trick of its own.


All cameras, regardless of make, have certain common features. Often, the biggest difference is in the naming convention used for a particular feature — Canon use Av and Tv for Aperture Priority and Shutter Priority respectively, instead of the more commonly used A and S.

If this is your first interchangeable lens camera or you've just switched from another camera system it can be slightly confusing until you've learned the new "language," but the following two chapters should help you cut through that confusion. However, if you're reasonably familiar with Canon DSLRs you may want to skip the first half of this chapter and go straight to the more detailed explanations of functions after that.

Whatever your level of experience you'll find the EOS 70D is a well-specified camera. It can be used as a "point-and-shoot" camera or you can take full control for greater creative fulfilment. Whichever way you choose to shoot, experimenting with your camera will pay dividends: familiarity will help you make creative decisions quickly and avoid missing photographic opportunities.


CAMERA PREPARATION


Attaching the strap

It's a heart-stopping moment when a camera falls to the floor. One way to minimize the risk of this happening is to fit the supplied strap, which allows you to either wear your EOS 70D around your neck or keep it secure by wrapping the strap around your wrist.

To attach the strap to your EOS 70D pull one end of the strap out of the attached buckle and plastic loop and then feed it through either the right or left strap mount on the side of the camera. Feed the end back through the plastic loop and then under the length of strap still in the buckle. Pull the end of the strap so that is fitted snugly in the buckle. For safety, allow at least 2 inches (5cm) of strap to extend beyond the buckle. Repeat the process on the opposite side of the camera.


Using the viewfinder

All recent Canon digital cameras allow you to compose a shot using the rear LCD screen switched to Live View, but the advantage of a DSLR like the EOS 70D is that you also have the option of using the optical viewfinder. In many ways this is the better choice, as it helps to conserve the camera's battery power and it is also easier to hold a camera steady when it's against your face, rather than when it is held at arm's length.

A disadvantage of the EOS 70D's viewfinder is that you only see 98% of the scene, so the camera will capture more of the scene than expected. Fortunately, this 2% difference isn't too significant. To get round this problem you could either crop the image in postproduction or compensate before exposure by fractionally zooming in with the lens (or taking a small step forward if using a prime lens).

The focus (or diopter) of the viewfinder can be adjusted to compensate for individual variations in eyesight. The adjustment range is -3 to +1 m-1. To alter the diopter, look through the viewfinder and move the diopter adjustment wheel up or down until the display at the bottom of the viewfinder appears crisp. Adjusting the diopter will not affect the focus of the camera.


Fitting and removing a lens

The joy of using a DSLR like the EOS 70D is that it's possible to change the lens to suit your needs for each individual shot. To fit a lens, first switch off the camera and then hold it so the front is facing toward you. Remove the body cap (or lens if one is already fitted) by pressing the lens-release button fully and turning the cap to the left until it comes free easily.

Remove the rear protection cap from your lens. If you're fitting an E-FS lens, align the white index mark on the lens barrel with the one on the camera lens mount. If you're fitting an EF lens, align the red mark on the lens with the red mark on the camera lens mount. Then, holding the solid part of the lens, gently push it into the lens mount until it will go no further and turn the lens to the right until it clicks into place. To remove a lens, reverse the procedure above. If you're not fitting another lens immediately, replace the body cap on the EOS 70D and fit the rear cap onto the lens you've just removed. See chapter 4 for more information about lenses.


POWERING YOUR EOS 70D


Battery charging

The EOS 70D is supplied with an LP-E6 battery that must be fully charged before first use. Remove the cover from the battery and slide it in and then down into the supplied LC-E6 or LC-E6E charger so that the word "Canon" is in the same orientation on both the charger and battery.

Connect the LC-E6E charger to the AC power cord and insert the plug into a wall socket, or plug the LC-E6 charger directly into a wall socket after flipping out the power terminals. The charge lamp will blink orange once per second, and as the battery is charged the rate of blinking will increase: at three blinks per second that battery will be approximately 75% charged, and when charging is complete the charge lamp will glow green. Once the battery is charged, unplug the charger from the wall socket and remove the battery by pulling it up and out from the charger.

A normal charge for a depleted battery will take approximately 150 minutes. The amount of charge left in a battery is shown on the top LCD (see table below). When fully charged the battery should be able to power your EOS 70D for approximately 920 shots at room temperature when using the viewfinder to compose your images, or 210 shots when using Live View. This is reduced to approximately 850 and 200 shots respectively as temperatures drop close to freezing.


Inserting and removing the battery

To insert the battery, switch the camera off and turn it upside-down. Push the battery cover release lever toward the center of the camera. The cover door should then open easily. With the battery contact terminals facing down and to the center of the EOS 70D, push the battery into the compartment with the side of the battery pressing against the white lock lever as you do so. Once the battery has clicked into place close the battery cover. To remove the battery, push the lock lever away from the battery and gently pull it out.


Battery life

The LP-E6 battery supplied with the EOS 70D is a rechargeable lithium ion unit. Lithium ion, or li-ion, batteries are remarkably small and lightweight for their power capacity. However, the EOS 70D's battery will inevitably deplete when used, and also slowly discharge when it is removed from the camera.

The more efficiently you use your EOS 70D, the longer the battery will last. Using the rear LCD to constantly check your images (known as "chimping") is particularly power draining so try to keep the use of the LCD to a minimum. Using Live View compounds the matter, as it requires the sensor to be permanently active as well as the LCD, which puts a further strain on the battery. Keeping Image Stabilization (IS) switched on (if a lens has this feature) will also cause the battery to deplete more quickly.

Ambient temperature has a big effect on the efficiency of a battery. Cold conditions will cause your battery to deplete more quickly than usual. Therefore it's worth carrying a fully charged spare battery with you on days when the temperature is close to freezing.


BASIC CAMERA FUNCTIONS

It takes time to get to know a camera well. Ultimately this means using your EOS 70D as often as is practicable, as getting to know the layout of the controls could be the difference between capturing a shot and missing it. Fortunately, Canon has made the EOS 70D ergonomically similar to other models in the EOS range, if you've used another Canon camera you'll quickly get to grips with this one.

Throughout this book I'll be referring to the buttons and controls by using shortcut symbols. To use the various menus and functions (assuming you're not using the touchscreen) you'll mostly use the Main dial [??] behind the shutter-release button, the [??] Quick control dial on the rear of the camera that surrounds the multi controller. If you need to use the multi controller you'll see either a specific direction arrow (* for left, * for up, * for down, and * for right) or * if you have a choice of which direction to press. The Setting button (SET) at the center of the multi controller is used to confirm a function or menu choice. Other buttons on the camera will be referred to by their name or relevant symbol. When you come across words in bold type these signify options that are visible on a menu screen.

In shooting mode you can switch between several different shooting information screens on the LCD by repeatedly pressing INFO.. One of the more useful of these is the virtual spirit level, which is an excellent aid to keeping your camera straight. Pressing INFO. in playback mode will cycle through a series of screens showing varying degrees of information about the currently displayed image.


Switching the camera on

The power switch is found below the Mode dial. Switched to OFF, the EOS 70D is entirely inactive. When the camera is switched ON, the Access lamp will flicker briefly, automatic sensor cleaning will be activated, and the top LCD will display the current shooting settings.


The LCD monitor

The viewfinder conveys some information about the configuration of the EOS 70D. However, the same information — and more — can be found on the LCD. This information includes the currently selected shooting settings, a Live View display that displays a live image directly from the camera's sensor (optional when shooting still images or automatically selected when shooting movies), a comprehensive menu system, and the playback function to review images.

The LCD of the EOS 70D is also touch-sensitive so you can select camera functions, without pressing buttons or turning dials. How you control your camera is very much a personal preference, though.

The LCD is hinged and can be rotated so that it faces into the camera. This is useful to avoid the LCD becoming scratched when you're not using your camera. To view the LCD, first pull it out from the camera 180°, and then rotate it forward, toward the front of the camera, by a further 180°. Push the screen back into the camera so that it fits snugly with the screen facing outwards. The LCD can of course be used at any angle, which is particularly useful if you want to use your EOS 70D close to the ground or above head height.


Using the touchscreen

You can set the various functions on your EOS 70D one of two ways: by pressing buttons and turning dials, or by using the LCD touchscreen. Which you choose is entirely up to you.

There are three ways that you can interact with the LCD. The first method is to simply touch an onscreen option to select it; this is useful when using the menu system or [Q] screen. You can also select OK or Cancel to confirm an alteration to a function by touching the relevant option on the LCD. Touching can also be used during Live View, either to select a focus point or to fire the shutter when Touch Shutter is set to Enable. Whenever arrows are displayed on screen you can touch these to make alterations to settings in much the same way as using the multi controller.

The second way to interact with the LCD is to slide your finger across the screen. This is used to adjust functions that use sliders, such as exposure compensation. When viewing images in playback you can use a left-to-right sliding motion to quickly skip through images on the memory card.

The third way to interact with the LCD is to use two fingers and either bring them together or pull them apart. This action can be used to zoom out or zoom in respectively when viewing images.
