Understanding Which Digital SLR Camera Lens Is True For You? - How The Top SLR Cameras Work
When shopping for a Digital SLR Camera people often overlook or skimp on the camera’s lenses. Camera Lenses provide as the digital SLR cameras “eye,” the lens concludes what & how your camera will see your subject & how well that view is transmitted to the camera’s sensor chip for recording. The way I like to look at camera lenses is as painter’s brushes broad strokes medium stokes all purpose brushes & small detail brushes. The following sections make clear the basic types of SLR Camera Lens how they do & how to choose them.
Focal Length
On a digital SLR camera the focal length of the lenses measures the space between the lens & the image sensor measured in millimeters. Lenses can be classified into subgroups like prime macro wide angle normal telephoto & zoom lenses.
Prime Lenses:
Prime lenses are fixed focal length lenses like a 50mm 1.4f lens. Traditionally prime lenses are sharper & quicker then zoom lenses.
Macro Lenses:
Examples of macro lenses are 50mm & 100mm macros. These lenses are also large for selective focus types of photos.
Wide-angle Lenses:
Wide-angle lenses are your broad stroke brushes; these types of lenses have short focal lengths. A way to confirm if the wide-angle lenses you are interested in has convergence is to take test pictures before buying the lens. With high quality wide angles lenses like Canon L series lenses address this convergence issue well. Examples of wide-angle lenses are 15MM 17mm 24mm & 28mm lenses.
Normal Lenses:
If you buy just one lens try & get the fastest normal lenses you can like a 50mm 1.4f lenses. Some examples of normal lenses are 35mm; 50mm 65mm & some consider a 80mm a normal lens.
Telephoto Lenses:
Lenses with long focal lengths 100mm & higher are called telephoto lenses. Telephoto lenses also provide your subjects a graphic look & flatten out your subject. These lenses are my short stroke brushes.
Zoom Lenses:
Zoom lenses are special because they can be very versatile. These types of lenses vary in their focal lengths & come in many in wide-angle telephoto & wide-angle to telephoto. In my bag I carry a 17mm to 35mm my wide-angle broad brush 24mm to 70mm my medium brush & a 80mm to 200mm my short brush. When shopping for a zoom lenses check out the f-stop range rating. Zoom lenses can give you flexibility & versatility all in one lenses.
The meaning of the SLR acronym is Single Lens Reflex.

What I’m trying to say is that digital SLR’s are versatile cameras.
The digital SLR mechanics
Here I’ll try to describe a bit how a digital SLR camera works.
1. After the light goes through a lens it hits the mirror
2. Then the light is sent on a focusing screen
3. After the focusing screen the light goes to the pentaprism a block of glass
4. From the block of glass the light goes to the viewfinder so you can see it.
5. Taking a photo means that the mirror is flipping with the shutter opening & exposing the sensor to the light.
