G Lenses produce superior in-focus image quality, as well as beautiful defocused background.
These are different aperture values f/1.4, f/2, f/2.8, f/4, f/5.6, f/8 (high to low) It is calibrated in f/stops and is generally written as numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16. The lower f/stops give more exposure because they represent the larger apertures, while the higher f/stops give less exposure because they represent smaller apertures.
A lens that has an aperture of f/1.2 or f/1.4 as the maximum aperture is considered to be a fast lens, because it can pass through more light. This is the reason behind using lenses with large apertures that better suits low light photography.
A lens mount is an interface — mechanical and often also electrical — between a photographic camera body and a lens.
Camera shutter is just like a curtain in front of the Camera sensor that remains close till the camera fires. Camera's shutter controls how long the sensor is exposed to light. It uses a pair of 'curtains' or blinds. The button that fires the camera is known as shutter or shutter button, because it triggers the shutter to open and close.
Shutter speed also referred as exposure time is the time when the camera shutter is opened to expose sensor to the light. There are some times when you require fast speeds like sports or action photography, but there are other times that you can slow things down a little and get some very nice results indeed.
Shutter speed is generally measured in fractions of a second. Eg: 1/250 means one two-hundred-and-fiftieth of a second or four milliseconds. Most modern DSLRs cameras have shutter speeds of up to 1/4000th of a second, while some high end cameras can handle much higher speeds of 1/8000th of a second and even faster than that. The longest shutter speed on most DSLRs is typically 30 seconds i.e. without using external remote triggers.
Image Sensor and Processing
Dust Deletion Feature
Dust Delete Data is a piece of data that is appended to the photos that are to be used for dust detection and deletion using Canon’s Digital Photo Professional application (DPP) provided on the disk that comes with your Canon 70D. It maps the spots where dust is detected and writes the size and location to the appended data file for DPP to use.
Image sensor format
The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular camera. In particular, image sensors in digital SLR cameras tend to be smaller than the 24 mm × 36 mm image area of full-frame 35 mm cameras, and therefore lead to a narrower angle of view.
Camera User Interface
A device on a camera showing the field of view of the lens, used in framing and focusing the picture.This is the view of the world through the camera, the small rectangle with black edges that shows you what part of the world the lens is looking at and whether it is in focus or not.
The viewfinder is the only important user interface on any camera.
Built-in Dioptric Adjustment
A diopter is a setting on your camera body that adjusts the image in the viewfinder to match your eyesight.They adjust for an eye that can’t focus at a reasonable distance, such as for close objects like reading text.
AF area selection mode
Auto Area AF uses color information and special face recognition algorithms to automatically focus on an individual’s face, which is extremely helpful when there’s simply no time to select a focus point.
Now-a-days camera comes with an autofocus assist light which helps the camera determine autofoucs in low light conditions.
It allows you to focus on the most important part of your scene you want to capture and then hold that focus while you recompose the shot, ensuring your final image has the correct parts in focus.
The metering mode refers to the way in which a camera determines the exposure. Now-a-days camera comes with light “meter”, which is a sensor that measures the amount and intensity of light.Metering is all about how your camera determines what the correct shutter speed and aperture should be, depending on the amount of light that goes into the camera and the sensitivity of the sensor.
Exposure compensation is used to alter exposure from the value selected by the camera, making photographs brighter or darker.
AE lock (Auto)
When you press the AE Lock button, the current exposure settings are locked so that they can’t change as you recompose the shot even if the level of light alters as you aim the camera elsewhere.
Exposure bracketing is the technique of taking three or more shots of exactly the same scene using a different exposure setting for each one.

Live View Shooting
This is a technique is used to measure the brightness of the subject in front of the camera. Then the camera optimizes exposure by adjusting aperture, shutter speed, (f-number), and ISO sensitivity accordingly with the brightness of the subject, which is measured using the camera's built-in metering sensor.
Optical Image Stabilizer
OIS is a mechanism used in a still camera or video camera that stabilizes the recorded image by varying the optical path to the sensor.
The drive mode function within a camera can be used to change whether your camera shoots single or multiple shots once the shutter is full depressed. It can also be used to delay the shot by waiting 2 or 10 seconds to take a photo after the shutter has been pressed.
