SLR Camera Lenses - Top 5 Bestsellers and Why

Many people looking to buy a second lens for their digital SLR camera are baffled by the number of lenses available. There are so many to choose from, it's easy to be overwhelmed by the choices. Check out these 5 top SLR camera lenses and discover why people love them so much.

1. Canon EF-S 55-250mm f/4.0-5.6 IS Telephoto Zoom Lens

The key to this lens is the image stabilization. The stabilization allows more photo ops without having to use a tripod. This makes for more crystal clear photos at Johnny's soccer game, or capturing a flock of birds at take-off. Image stabilization is an absolute must on a hand-held zoom telephoto lens.

2. Canon EF 50mm f/1.8 II Camera Lens

For people looking for a fixed focal length, this lens is lightweight and affordable. The images are sharp with great color balance. It's great for portraits and it focuses as close as 18 inches, so you gardeners will find this lens very useful. Most people who use this lens can't stop talking about the picture quality.

3. Nikon 70-300mm f/4.5-5.6G ED IF AF-S VR Zoom Nikkor Lens

This Nikkor telephoto zoom len also has image stabilization which they call Vibration Reduction. It's the Nikon version of the Canon listed above. The lens is ideal for sports, action, wildlife, and travel when you want a telephoto lens. The fans of this lens love it for capturing sports and action.

4. Nikon 50mm f/1.8D AF Nikkor Lens

Like the 50mm Canon lens above, this lens has a fixed focal length. But the quality of the pictures outweighs the fact that you need to move your feet around alot to get the shot. It's really versatile and should be in everyone's camera bag. Fans of this lens say it works great in low light situations both indoors and out.

5. Nikon 55-200mm f/4-5.6G ED IF AF-S DX VR [Vibration Reduction] Zoom Nikkor Lens

This Nikkor telephoto zoom lens is great for professional or advanced amateur photographers. It helps you capture close-up sports shots and national park wildlife without standing right next to your subject. The Vibration Reductions extends the use of the camera to capture more shots while hand held. Like the telephoto lenses above, the lens is slower than a professional zoom, so it's not a good choice for action photography in lower light conditions (like indoor sports without flash or outside sports at dusk).

Now obviously, these SLR camera lenses are only suitable for Canon and Nikon camera fans. But take this information and find a lens that works with your camera. You'll explore an exciting new area of photography and take your hobby or profession to a whole new level.

How To Use Lens Aperture Correctly

All camera lens apertures are controlled by a metal-bladed iris. The size of the iris can be set by the photographer using the standard aperture scale, which begins at 1, (the maximum aperture) and decreases on a logarithmic scale that is based on the square root of 2, which has the value 1.4142.

The trick really is to use an aperture with a shutter speed that gives the correct exposure. Fortunately, with today's digital cameras all you need to do is to select the appropriate aperture and the camera's electronics will select the correct shutter speed to give the right exposure.

This will always happen on a D-SLR that is set to Aperture Priority mode. If you want to get creative you can always put a D-SLR in Manual mode and independently set both the aperture and the shutter speed. Normally you choose the aperture first, and then set the shutter speed. If you do it in reverse it will not work.

You need to understand that when selecting large apertures you will always produce photos that have a shallow depth-of-field. This means that the background in particular and sometimes the foreground of a subject is out of focus. This result is ideal for portrait images, and when you do not want any distraction in a scene.

If you need much more of the image to be in focus you will need to select a smaller aperture. Unfortunately, a smaller aperture means that there will be less light entering the lens and therefore the shutter speed will be automatically reduced to maintain a good exposure.

A slower shutter speed means that there is more chance of experiencing camera shake, which inevitably leads to image blurring. It is a fine balancing act really. Either you lose depth-of-field to attain the right exposure, or you get blurring because there is not enough light.

However, there is a neat way around this problem. To reduce the risk of image blurring all you need to do is to set your camera on a bean bag or tripod, then use a remote release cable or the camera's timer, and away you go.

Lens aperture measurements are really fractions of the len's focal length and are expressed as f/numbers, like f/2.8, f/5.g, f/16, etc. These are also called f/stops, or just stops. The larger the f/number, the smaller is the aperture. So an aperture of f/22 is a lot smaller than one of f/6.3.

You can easily master lens aperture providing you follow the proven principles in this article. Mastering lens aperture is not difficult - it can be done. Use these strategies and very soon you could be the expert photographer you know you can be.

New Sigma APO 50-500mm F4.5-6.3 DG OS HSM. This is a 10x high zoom ratio ultra telephoto zoom lens incorporating Sigma's original Optical Stabilizer function. This lens covers a wide range of focal lengths from 50mm to 500mm ultra telephoto. The OS (Optical Stabilizer) function offers the use of shutter speeds approximately 4 stops slower than would otherwise be possible.

This lens is equipped with a Petal-type hood to block out extraneous light. The filter size of this lens is 95mm and the lens is supplied with a step down ring enabling digital cameras with an APS-C size image sensor to use an 86mm filter. *It is not possible to use a Polarizing filter with the step down ring. If you attach a Polarizing filter, you may not be able to remove it from the lens again. *For Pentax and Sony mounts, it is not possible to use the AF and the built-in OS function of this lens when attaching it to film SLR cameras as well as Pentax K100D. *Nikon and Pentax mounts do not have an aperture ring. Some functions may not work depending on the camera model.

Zoom Lens With DSLRs May Offer a Surprise

If you are shopping around for your first ever DSLR camera, then there is one factor that you might want to learn about and that is the "crop factor." The reason that this feature is important is that it might give you a different lens performance than you expect. When it comes to compact digital cameras, what you see is that you get and if the compact camera comes with a 35mm equivalent lens, then you would get the same performance as a 35mm lens. However, this is not necessarily true in the case of DSLR cameras.

The sensors of most DSLR cameras is smaller than a 35mm film and a camera with 1.5, 1.6, or 2.0 crop factor will capture smaller area and "crop" the view. If you use a lens with 100mm focal length and the camera has a 1.5 crop factor, then the final, adjusted focal length would be 150mm. The photographers that are likely to take more indoor or landscape photos are the ones that should be typically concerned with the crop factor or at least take it into account when buying lenses for their DSLRs. However, if you take more wildlife, portrait, or macro shots, then you might not have to worry about this issue at all. One way to work around it though, is to purchase a DSLR that has a zero crop factor, or a full-frame DLSR. These cameras typically cost more and depending on your needs, purchasing one might not be justified at all.

Another fact that is good to know is that all camera manufacturers use a consistent crop factor for their cameras and therefore the number does not vary from one camera model to another within the same brand. The terms focal length multiplier and focal length conversion factor are often used instead of "crop factor" and the most common numbers are 1.5x, used by Nikon and Sony, 1.6x, used by Canon, and 2.0x, used by Olympus.

Factors to Consider When Buying a Camera Lens

Purchasing a DSLR or Digital Single Lens Reflex camera comes with a basic kit lens that could give decent quality pictures. But the advantage in DSLR cameras is being able to switch lenses, depending on the type of shot you want. There are powerful zoom lenses or macro lenses, for example.

Here are some factors to consider when buying a digital camera lens:
The Glass
o Focal Length - It is the actual distance in-between the focal lane of the lens and the rear element, measured in millimeters (mm). This is where the light's parallel beams enter the lens converging onto a point. It determines the viewing angle of the lens. When there is a shorter focal length, the field of view becomes wider, providing more scenes for your camera to capture. When you increase the focal length, the actual field of view becomes narrower.

o Aperture - It is one of the mechanisms that control the actual "amount of light" passing through the lens towards the image sensors. It is also referred as "f-stops," like f/2/8. The smaller the number, the larger the opening. This means more light enters the camera. Since it begins to collect additional light, a type of lens that allows you to open to a wider aperture also enables you to have a faster shutter speed. Such feature is essential in low lighting conditions to obtain sharp images, especially through a handheld camera.

o Image Stabilization - Slower shutter speed can result to blurry photos when cameras are handheld. Image stabilization counteracts the shaking, allowing one to shoot certain handheld shots amidst low lighting conditions. Canon's term for this is IS (Image Stabilization). Nikon use the term VR (Vibration Reduction).

Zoom lenses included in a variety of DSLR kits offer focal lengths ranging from 18 to 35mm. Depending on the cropping capability of the camera, it can reach up to 55mm. This means that you can go from only a moderate "wide-angle" view towards a so-called "slight telephoto."

If you have plans of expanding your digital camera's features, here are some things you need to consider:
o Prime Lenses - These should possess a longer type of zoom lens or a lone focal length between 35mm up to 85mm. Prime lenses have a better glass on them.

If you get the "fixed-length lens", there is a tendency that you will be required to move around when getting your shot. Of course, over a certain time, this will already help you make better compositions. Prime lenses also possess a wider type of maximum aperture, making it easier to get sharper shots, especially under low lighting.

o Zoom Lenses - For those wishing to get action photos, the best would be the "telephoto lens" which ranges from 100mm up to 300mm. This is due to the DSLRs crop factor. There is not much zooming needed. A good example would be Nikon D40 which has a 200mm type of telephoto lens that can turn into a 300mm one.

Important Spy Camera Pieces

A spy camera is a complicated piece of equipment that's actually quite easy to explain. A camera lens transmits images to a receiver which then broadcasts those images on a TV screen, monitor or even on a personal computer. And while inside each component of your nanny camera is a complex section of wires and circuits, it's those two important units that make your nanny camera what it is. Without them - and without having them function properly, your micro spy nanny cam will simply be a high-tech piece of junk that won't actually do anything that you want it to.

So, we've determined that the camera and the receiver are the most vital components of a spy cam. Let's elaborate on those pieces so that you can enjoy a better understanding of exactly what they do, how they work and how they contribute to enhancing the safety and security of your family, home or business location.

Camera Lens

This is your eye when you can't be there to watch and see for yourself. The camera is the part that actually catches and records everything that happens within its field of vision. The great thing about the camera lens is that they can be incredibly small in size. There are exceptionally small camera lenses - called pinhole lenses - which are literally less than 1" in diameter. With spy cams, it's important to always understand that the camera lens is your window to everything that's going on. Without it, you won't see anything and your nanny camera won't record anything.

That's why pinhole camera lenses are so valuable. You can place them just about anywhere and not have to worry about anyone locating it or detecting it. Remember, the camera lens has to be in some clear location where it can have an unobstructed view. An exceptionally large camera lens will be easily discovered, thus neutralizing the "hidden" aspect of the spy camera. But, a small lens can be placed in any room and nobody will ever know that it's there.

There's one truth to always remember when it comes to spy cameras and the behavior of people: when people know that they are being watched, they will modify their behavior to make themselves appear in a favorable light. When they think they're alone is when their true behavior and intentions come to the forefront. A well hidden camera lens will always capture and record the truth, because nobody will know that it's there.

Receiver

Just as important as the camera lens is the video receiver. When you're super-small pinhole lens is recording video, it's got to send that video information somewhere. That somewhere is the receiver. For a majority of spy cameras and nanny cams, the receiver plug into a standard wall outlet. At the same time, the receiver is also connected to a TV, computer screen or viewing monitor. This allows you to watch the video that your camera is recording - in real time - directly on your television set.

The reason that this part is important is quite obvious actually: without it, you couldn't see what your camera recorded. Many people, when they use a spy camera, they intend to watch the footage that the nanny cam captured while they were away at a later time. Without a reliable, strong receiver, your camera won't be able to transmit any image whatsoever, thus rendering it completely and utterly useless. You should always endeavor to ensure that your camera receiver is kept in pristine condition at all times.

Your receiver will always be in tune with your camera lens, which means that you'll be able to set them up so that they'll always work together. Cameras and receivers are designed to work in conjunction with each other, and they aren't designed to be mixed and matched with other spy cam products or brands.
