Another unusual feature is the fact that the infrared filter is fitted to the lens mount rather than the sensor and doubles as a dust protector, sealing the mirror and sensor compartment, and can be removed easily, to allow infrared photography. The image sensor captures pure, rich light efficiently and gives the SD14 its high resolution.
Physically, the SA mount is identical to the PK mount with a reduced back-focus of This provides a not so obvious but very interesting option that most Canon EF-mount lenses will work seamlessly after exchanging the mount plate with the Sigma DSLRs, but without image stabilization. Pentax K-mount lenses physically fit, but should only be mounted when the rear protrusions have been dismantled. Such lenses will then focus beyond infinity and may contact the protective filter.
A spacer ring made e. Prime as opposed to zoom lenses often permit a simple resetting of the position of the focusing ring on helical inside.
P, S, A, and M modes are known as exposure modes and give photographers a choice as to which elements of exposure—aperture or shutter speed—they wish to control. The camera automatically adjusts aperture and shutter speed for optimal exposure, but the photographer can choose from different combinations of aperture and shutter speed that will produce the same exposure.
This is known as flexible program. The photographer chooses the shutter speed and the camera automatically adjusts aperture for optimal exposure.

In this lesson, you will explore the basics of your DSLR camera such as buttons, and controls, and the exposure mode options for different shooting situations. This lesson also covers some general maintenance and housekeeping issues with memory cards, batteries, and cleaning-and by the end of this lesson, you will feel empowered to get started with your DSLR camera.
This lesson is all about DLSR lenses. One of the most important features of the DSLR is the ability to change lenses based on shooting conditions. You will find out how lenses work, some of the most common DSLR lenses, and what shooting conditions those lenses can help you.
Do you know how your camera sees a photo? In this lesson, you will learn about the three components of exposure-aperture, shutter speed, and ISO.
You will also learn about metering modes and how your camera uses these to determine the correct exposure for a photo. The previous lessons introduced the aperture, but this lesson will discuss it in depth. You will learn how this aspect of exposure controls how much light enters the camera, and you will discover how to control this light to affect the quality of your photos as well as certain focusing effects. Both have positive and negative aspects for photographers.
There are some ways to retrofit old lenses onto new cameras, but they might need to be the same brand, and you may lose some important technical tools, like the light meter.
Using a tripod will ensure a crisper and cleaner image. For analog photographers , the type of film and brand you choose will affect your photographs.
The most common brands to choose from are Kodak, Fuji, and Ilford, but there are others. The most common 35mm film is measured in ISO , or speed, ranging from to Each speed will create a different effect. Higher ISOs are best used in lower light, while lower ISOs are better for brightly lit interiors or full sun outdoors. A standard speed to start off with would be ISO , which can be used indoors and outdoors with adjustments to your settings. The aperture consists of small blades in the lens that create an adjustable, octagonal shape.
It tells you how big the hole is in your lens. The smaller the hole is, the less light passes through it. The wider the hole is, the more light will enter your lens. The aperture is measured by your f-stop. The higher the f-stop f22 , the smaller the hole and the darker your image will be. The f-stop also measures the depth of field. A lower f-stop f2. For example, if you are taking a photo of a person and would like the background to be a bit blurry, you would choose a low f-stop.
If you are taking a picture of beautiful scenery, you would want a higher f-stop to make sure everything is in focus. The shutter speed tells you the amount of time the camera will be exposed to light. Using a faster speed means the image will be darker. If you would like to lighten the image, use a slower shutter speed.
