Overcoming Digital SLR Canon Crop Factor of for wide-angle photography

The crop factor, digital SLR or multiplication factor of the lens, has the effect of crop the edges of an image, broadening the central area. The end result is similar to using a longer lens, or a tele converter.

The effect of clipping occurs because the sensor on most digital SLR cameras is smaller than a 35 mm slide or negative.A "frame" of 35 mm film is 36 x 24 mm in size, while the sensor Digital Canon Digital Rebels (300 to 500 d) and the EOS ** range D (50 D 20 d and 7 d) is only 22.5 x 15 mm in size. a sensor smallest to receive the image means that some of the image will be cropped.

Think of it this way: you're watching a presentation on a screen that is just big enough to accommodate the full-size image, and then someone replaces it with a screen that is smaller. Now some of the projected image (top, bottom and sides) "overflow" the small screen, so that what you see now is a version of the image cropped.

You get a similar result when using a digital SLR camera with a sensor that is less than a piece of 35 mm film--the image expressed by lens "overflow" sensor. Any spare space around your subject is cropped away, so the subject now fills most of the frame--but if there is no spare space, part of the subject itself gets cut.

This cutout or magnification is an advantage when using a telephoto lens, as the result is similar to using a longer lens or 1,6 x Converter.

However, for anyone wide-angle shooting, the opposite is true. Now that terrible wide angle so appreciated for creating dramatic landscapes or indoors close is made useless seeds.A real wide-angle as a Canon EF 24 mm gets "stretched" 1.6 x, giving him a focal length equivalent of 38.4 mm on your Rebel XSi or 50 D.

Fortunately, Canon and other digital SLR manufacturers realized that they had to produce lenses for overcoming the crop factor for photographers using wide angle lenses.

The result is a range of lenses for digital SLR cameras with smaller sensors of 35 mm film (often called sensors APS-C format). While the crop factor still applies when using these lenses, the lenses themselves are "shorter", both physically and in focal length, than the lens equivalent to a 35 mm camera.

So the kit lens for Canon Rebel is THE EF-S 18-55 mm.This should be classified as "ultra wide" (wide end) to a 35 mm camera, but equals one more mundane 28.8-88 mm standard zoom--or--when used with a Rebel XSi or 50 D.

While the rebels and EOS Canon ** D digital SLR are classified as entry-level or "prosumer" cameras, they are also used by professionals, in particular, wedding photographers, not previously be adequately met by wide angle lenses available, particularly in terms of image quality and the focal length.

To work around this, Canon has introduced two lenses that are standouts within its range of lens EF-S for use on rebel and EOS ** D cameras:

* Canon EF-S 17-55 mm f/2.8 IS USM
* Canon EF-S 10-22 mm f/3.5-5.6 USM

THE EF-S 17-55 mm is notable for its constant aperture of f/2.8 throughout the zoom range which, together with image stabilization, makes it particularly effective for shooting in low light without flash. It is highly ranked by photographers of wedding and portrait and also as a walkaround lens.

Users like the lens for its sharp pictures at all focal lengths, autofocus fast, versatile and excellence in low light conditions are Their main dislikes. the price (is the most expensive EF-S lens), insufficient Weather sealing, plus the size and weight.

It however receives a score of 91% of users and is a highly recommended as a top quality lens for APS-C format cameras.

THE EF-S 10-22 mm is remarkable, as is the only true ultra wide angle for Canon Rebel EOS ** bodies d. Adapt this objective on your Canon 40 d and is equivalent to a 16-35 mm on a 35 mm or full-frame, offering creative photographers opportunities not otherwise possible with APS-C format cameras.

Users as an objective for its excellent sharpness, colors, autofocus fast and minimal distortion. They don't like the price, construction of plastic and lack of a lens hood supplied.

But the image quality is favourably compared to that of a Canon l series, and users give a rating of 90%, recommending it as essential for anyone who wants wide-angle real capacity on a rebel or EOS ** D body.

Users of Canon Rebel or EOS ** reflex D you can no longer blame their kit lens for less than stellar image quaility it--alternatives are available (although at a price).

What to look for when buying a Canon L Series

The l series of Canon offers a variety of interchangeable lenses. The goal of Canon is considered the best on the market. The lenses of Canon l series are a favorite among professional photographers and amateurs alike. Many new photographers do not understand why their camera didn't come with an objective already. Canon camera, unlike simple point and shoot cameras, you do not limit what manufacturers built into the camera. To capture incredible images and filmed the types of photos that interests you, it makes more sense for you to buy a lens that fits your needs. In this way you don't pay more money for a lens not using it.

Pickup lens for you is going to greatly depend on the type of photography you are going to do. The question of whether or not to use a normal or a telephoto lens or perhaps a wide-angle lens is going to be determined by the situation. For example, if you are a family gathering and your grandmother asks you to take a family photo and you take the time to squeeze all in pictures and just doesn't work.Your goal is not large enough. If you're out enjoying mother nature and want to capture a photo of a deer mama mozzafiata and his Faun and will grab the camera quickly obtain a perfect shot, only later to see what all you have are trees and blurry blob ... your goal was too short.

The l series of Canon lens gives you a variety of lenses that will have the trial and error out of your photograph. imagine having to not squeeze the whole family in one shot, or to obtain deer that actually MOM and child in the field and all you had to do was change your goal. You can take your wide angle lens for the family or telephoto to your shooting nature.

Of course knowing what is good for every goal is important as well. Wide angle Lenses allow you to fit more people in a shot. For example, a lens with wide Canon l series which is 28 mm is moderately wide whereas a 14 mm lens is a lens that you want to use for a landscape shot.Telephoto lenses are similar to telescopes that extends beyond the nearest objects, are also good to narrow down what you've seen in a photo. If you're taking photos of people at close range and shooting from the waist then a normal lens is fine. Zoom Lenses give you the possibility to adjust the field of view.Instead of making everyone in the family sitting on each other to squeeze in shooting, you can rotate the zoom ring until everyone in the photo.

Decide on the lens right to use for your type of photography is important.Know the type of photography and of what is important for every lens. Using a lens Canon l series will help you capture the most incredible images possible.

Wide Angle Lenses in Landscape Photography: Disadvantages

For many photographers, wide angle lenses are a large part of landscape and seascape photography and are used extensively throughout the field.

They are extremely popular and quite often produce incredible results if used properly.

Just like any lens that is used in landscape and seascape photography it also has some drawbacks and limitations that you need to know about.

Probably the biggest disadvantage of wide angle lenses is that when you attempt to take a photo of an object up close, they tend to distort and stretch the subject out of proportion which is not what we like to see.

Of course you may be trying to achieve this effect but most of us as landscape and seascape photographers aren't typically after that effect. The complete photo may be sharp except for the edges, this is again an undesirable effect but it's easy to avoid.

Your wide angle lens will be particularly prone to vignetting if you use a thick filter holder on it. You should always try and get a really thin filter holder so as to avoid the vignetting.

The final real drawback of a wide angle lens in seascape and landscape photography is that the zoom is very limited. They are fantastic for taking close up photos of objects but are almost useless when trying to capture objects that are a fair distance away.

There are more advantages than there are disadvantages when it comes to owning a wide angle lens but as with anything that you purchase, you just need to realize that there are some downsides to them. As with anything as long as you are aware of their limitations that a wide angle lens may have you should have absolutely no issues with using this type of lens.

If you are looking to buy a wide angle lens, you shouldn't stress out too much about the disadvantages as the advantages far outweigh them.
