Since the digital train makes its way around the world, you see the old track touch almost every part of our daily lives. revolutionized by digital chips in cars, coffee machines, telephones and credit cards, one of the industry is expanding in the digital photography.

While a film SLR cameras for almost a century, were the only digital SLRs have been around a decade. Once a luxury and only for a public professional digital SLRhave developed a camera that is now collected from the shelves of amateurs and hobbyists. This change was brought about falling camera prices, better image quality and capabilities of these cameras.

But because reflex?

Today's digital cameras have the best of both worlds: These cameras can range from a full manual camera with a camera point-and-shoot with Morph by turning a switch. Often sport higher megapixel image sensor, lens interchangeable, moreOn-board features, beefier and more durable body, shutter speed and the immediate response from the camera when the shutter button is pressed as standard digital point-and-shoot down.

Today, if you're used to point-and-shoot cameras is that there are several things you'll probably miss a reflex. To accommodate interchangeable lens mounts, compatible with older lenses, allowing for larger image sensors and simulates the feel of SLR TraditionalDigital SLR cameras are generally much larger than the point-and-shoot cameras. While there are many advantages to a larger body, tourists and those hoping to remain unnoticed, it is advisable to stay with the small boundaries, point-and-shoot cameras.

Another disadvantage of the comparison with DSLR cameras point-and-shoot cameras is that there is a live preview on the rear window. SLR shortage for two reasons: first, there is a trigger and a mirror blocking the path of light from the lens toImage sensor, secondly, more and more of today's digital SLR cameras are offering in CMOS image sensors, no way, with a live preview of the failure (which is less expensive to produce and consume less energy than using its rivals CCD) array of pixels in a map.

So while digital SLR for those who can not live preview, or need a small camera body, their capabilities are much greater than the point-and-shoot cameras – at a price.

Ok Let’s continue

Crop Reduction

Some lenses are designed to reduce this crop factor. While they cannot eliminate it completely, they can adjust for it.

Essentially, the lens is designed so that the back (the part that attaches to the camera) is closer to the digital SLR sensor.

Since the back of the lens is closer to the sensor, it reduces the amount that the small-sized sensor crops out of the image.

There is one big drawback to this type of lens: it won’t work with a film SLR camera. If you’re never going back to film again, then lenses like these won’t limit you one bit.

Image Stabilization (also called vibration reduction).

The stabilization helps when you are holding the camera in your hands and taking photos at slow shutter speeds.

Typically, this would result in a blurry photo, but with an image stabilization lens you can get clear shots. The stabilization corrects for the fact that the lens is shaking around.

This is especially helpful on lenses with long focal lengths (100mm or greater) since camera shake is magnified at long focal lengths.

You are going to pay a huge premium for an image-stabilized lens, but if you take a lot of photos in low-light conditions and don’t want to attach the camera to a tripod all the time, this is the way to go.

Image-stabilized lenses are NOT necessary with digital SLR cameras that include built-in anti-shake.

Superior Optics

Some lenses are designed with special optics that adjust for distortion, reduce flare and stray light from entering the lens and are designed to produce images with maximum clarity.

These lenses all come with different names

For example, Nikon used the term “ED” while Canon’s pro optics are branded with an “L”

Any one of these lenses is going to cost significantly more than a lens without the superior optics.

Internal Zoom

This really is a specialty feature, but it can make a difference. If you have a zoom lens with an external zoom, the length of the lens changes as you zoom from wide angle to telephoto.

With an internal zoom, the length of the lens is always a constant.

This is helpful for 3 reasons:

1. an internal zoom does not affect the balance of the camera. If you have your digital SLR attached to a tripod and use an external zoom, the changing length of the zoom changes the center of gravity of the camera.

2. internal zooms tend to be smoother and faster than their external counterparts.

3. external zooms can “slide”. This means that if you are pointing the camera toward the ground, the lens will zoom in unless you are holding onto the zoom ring.

The World’s Most Expensive Digital SLR Lens

Each one of these features will add to the price of your lens:

• Internal zoom
• Wide maximum aperture
• Full-time manual focus
• Superior optics
• Silent autofocus
• Image stabilization
• Long focal length
• Crop reduction
• Non-rotating front element

Hope that guide can help you.

The Canon 7D is an 18-megapixel semi-pro DSLR that shoots 1080p video in 24—or 30—glorious frames per second
The 7D feels like Canon took the results of a survey they handed out to people about what they wanted in a camera and crammed ‘em all into one product targeted at semi-pros. Full HD video with manual exposure in 24, 25 or 30 frames per second, check. More rugged, weatherproof body than 5D.

Customizable buttons, including a new multifunction button. A dedicated button for switching to RAW+JPEG mode.

Electronic axis level? It has dual DIGIC IV image processors, the first model outside of the pro 1Ds line with dual image processors for fast burst shooting: 8FPS with 94-shot JPEG bursts (124 with UDMA card) or 15 RAW shots, all at full resolution with 14-bit A/D conversion.
But, it’s not full-frame: They’ve crammed 18 megapixels into an APS-C-sized sensor (like in the Rebel series or 50D, versus full-frame in the 5D) with an ISO range from 100-6400, and a Hi setting of 12,800. Canon says they’ve shortened the distance between the photodiodes in the sensor, which decreases light falloff, supposedly translating into better high ISO performance.

Video
It might just be the best video on a DSLR yet: Manual exposure from the get-go, and oh yeah, the ability to shoot 1080p video at 30, 24 or 25 frames per second. If you cut it to 720p, you can shoot up to 60FPS. Also, video is encoded using H.264 now. There’s a dedicated switch to flip from shooting stills to video that encircles a start/stop button for recording, so it’s much easier to get right to shooting video than the 5D.

Other

Focusing system has 19 cross-type points, with a new way to focus in addition to the usual full-blast autofocus vs. single-point—zones, which are clusters of points. You can also lock different default focus points for horizontal and vertical orientations, so you can turn the camera back and worth without having to repick your focus point. (Setting it up is a little confusing—even the Canon rep took a minute to make it happen.) AI servo focus is supposedly smarter, so it tracks moving objects better, and it works with a new light-source detection system that adjusts for flickering light. (We didn’t get a chance to check that out.)
The viewfinder provides 100 percent coverage, like the 1Ds, and it uses a new polymer LCD network with a different graphics overlay than the 5D—that’s a lot like what Nikon’s got in the D300, In a first for Canon, the built-in, wide-coverage flash can command other wireless flash modules.

Here’s the list of features that manufacturers pack into modern digital SLR lenses:

• Silent autofocus
• Full-time manual focus
• Non-rotating front element
• Crop reduction
• Superior optics
• Image stabilization
• Internal zoom

Silent Autofocus

If you enjoy taking discreet photos or don’t want your subjects to be aware that you’ve got a camera aimed at them, this type of focus will give you away every time.

Common names for this include Ultra-Sonic Motor (USM) and Hyper-Sonic Focus (HSF). All that these really means is the lens is dead quiet when it is focusing.

It’s is also an essential tool for wildlife photographers

Full-Time Manual Focus

On most lenses, if you want to switch from autofocus to manual focus you have to flick a switch on the lens.

Since autofocus systems don’t always get it right, having the ability to focus manually all the time is helpful.

Some special set of lenses that feature full-time manual focus. This means that even if the autofocus for the lens is engaged, you can still focus manually to make fine-tuned adjustments.

Non-Rotating Front Element

On some lenses, the front of the lens rotates when you focus.

If you put a piece of tape at the top of your lens and then focused on your subject, the tape would not longer be at the top.

So the front spins around. It is a problem if you are a landscape photographer trying to use a polarizing filter on your lens.

A polarizing filter changes the light entering the lens depending upon how it is oriented. Let’s say that you set your polarizing filter just how you want it.

Now you focus, and the polarizer spins around. It is no longer capturing the same image as before, so now you have to re-set it.You’ll have to re-set it every time you focus.If you know for sure that you’re going to take landscape photos with your digital SLR, you’re probably going to want to use a polarizing filter at some point.

Make sure that the lens you get has a non-rotating front element.
