Save Your Hard-Earned Cash: Look into Used Canon Telephoto Lenses!

Canon telephoto lenses are a great asset for any photographer to own. However, there is one downfall…..these lenses can carry an expensive price tag. Owners of cameras with interchangeable lenses can build up a good set of optics without having to spend a fortune. The market for used lenses is vast and can save you a great deal of money if you choose the correct lens. Used Canon telephoto lenses are, for the most part, cheaper than brand new lenses. For instance, the Canon Zoom Telephoto EF 70-300mm f/4-5.6 IS USM Auto-focus lens can be purchased at a refurbished cost of around $400 compared to a brand new price tag of approximately $650.

It can sometimes be rather difficult to tell if a used Canon telephoto lens is garbage or not. Most camera owners realize that the quality of the image depends heavily on the lens and its condition. Therefore, when making a final decision on a used lens, all you can do is look for obvious signs of wear and tear before you make the final purchase.

The safest and surest way to make sure that you are purchasing the correct Canon telephoto lens is to test the lens on your own camera. Does the lens fit your camera and lock into place properly? Be aware that there are lenses out there that may be incompatible. This is due to the fact that many camera manufacturers have changed their lens mount designs at some point in their history. Are the proper displays appearing in the viewfinder? Does the indicated focus on the lens match up with the distance from camera to subject? These are all valid points to check when searching for a used Canon telephoto lens.

You can also check to make sure that the focusing, aperture selector and zoom control all work properly without being too stiff or loose. In order to check to make sure that the diaphragm opens and closes properly, simply look through the lens while you change the setting of the aperture. There is a problem if it sticks, and that can be a result of defective lubrication of the iris blades. This is something that will require a service technician’s attention and may be quite expensive to fix.

Factors such as finger-prints, scratches and abrasions to the external glass surface of the lens are something to keep an eye out for. Modern Canon Telephoto lenses are coated to reduce reflection and minimize flare; this coating can become damaged by reckless handling of the lens or careless cleaning habits. Never use a harsh cloth on your lens or a fluid such as window cleaner.

Now that you aware of some of warning signs to look for in your search, you may be wondering where you can find a used Canon Telephoto lens for your camera. Well, an online auction is one source. The only disadvantage is that you will not get the chance to examine and test the lens before you bid. The only information you will be able to secure is what the vendor provides in the description. I think that buying privately is much safer as long as you get the opportunity to examine and test the used lens before you commit to the sale.

Finally, the safest way to secure a used Canon Telephoto lens is to buy from a dealer that has a good reputation. This route may cost you a bit more money, but it is the safest way to go. Most dealers realize that you could potentially bring them future business and have their business image to protect.

More often than not, you will be able to take advantage of a warranty on the used lens. The bottom line is this is a great way for you to save money. Just be careful and do not inherit someone else’s nightmare!

Learn How to Properly Care for Your Canon Digital Camera

Canon, a leader in digital cameras, offers some of the best cameras on the market and their place in pop culture was confirmed in the 1970’s by use of their creative advertising on a variety of sports and outdoors shows. Ever since Canon has been a favorite among professional and amateur photographers alike. In more recent years, Canon has proven themselves again with their line of digital cameras which have proven to be quality, reliable cameras. However, just like any other type of electronic device, Canon digital cameras are not free from the damage that can be done from neglect or improper handling. With this being said, it becomes important to remember that you must take proper care when handling your Canon digital camera so that no damage is done and you cane get the most from your investment.

Store Your Canon Digital Cameras in its Case

It is always important to remember to return your Canon digital camera to its case when your are not using it. This will help save the camera and its lens from being scratched or banged mishandled. It will also keep the camera out of the harmful rays of the sun which can have a corrosive effect on your camera, additionally it will keep the various parts and accessories from getting lost or misplaced. Additionally, if the camera is in its case you will always know EXACTLY where the camera is at and will not have to scramble around looking for it when that perfect picture moment arises. (Unless, of course, you lose the case!)

You should always remember that ultimately, the camera case is a cameras best friend because of its ability to keep the camera safe and secure when not in use. However when you are using your Canon digital camera it will be up to you to protect the camera from damage.

As one can see, there are no magic formulas or secrets required for keeping Canon digital cameras safe, on the contrary, it is simply common sense and a desire to want to keep your equipment in good, functioning condition and to provide proper basic care. Sadly, some miss these basic points and this results in the damage being done to a number of excellent Canon digital cameras that should have had a much longer and happier life.

Don't Forget to Treat Your Canon Lenses with the Same Care

For those of you who happen to have a Canon SLR camera with a exchangeable lens it is important to adhere to the same principle of using common sense when not using a particular lens. Weather you use Canon wide angle lenses, macro lenses or Canon zoom lens, it is important to take good care of the lens and always store it safely when not in use. Again, this will ensure that your Canon camera lens, or lenses, will remain functional as long as your camera does.

So thats it, it only takes a little common sense and a little care to keep your Canon digital camera and your Canon lenes operational and in good shape.

Canon Macro Lenses: What Are They?

A true macro lens is one that can create life-size image – 1:1 magnification or greater. Canon macro lenses come in a wide variety with focal lengths from 50mm to 180mm. Most of these lenses will take you up to life-size magnification. However, one lens starts at life-size, rising to five time’s life-size magnification.Macro lenses are not just used for macro photography. For the most part, this is what they were designed for, but most focus to infinity as well.
This makes Canon macro lenses exceptionally versatile lenses that can be used for a variety of reasons besides just photographing fine detail.The essential difference between a macro lens and an ordinary lens is that the optical elements of a macro lens can move over a greater range. This allows them to bring subjects at a closer distance into sharp focus.
This would be a great advantage for taking photos of stamps or coins as the details of the items would be more defined. If you compare two equivalent focal length lenses, for example, the EF100mm f2 USM and the EF100mm f2.8 Macro USM, you will see that the close focusing distance of each is very different.
The macro lens can focus sharply on a subject just 31cm away from the lens, while the non-macro lens can only focus on a subject if it is 90cm away or further. Being able to focus closer, the macro lens magnifies an image more. In this case, a subject 31cm away will be recorded as life-size. Compare this with the non-macro 100 mm lens. A subject at its closest focusing distance will only be recorded as 0.14x the actual size. In other words, if the subject is 10cm long in real life, when recorded on film or on the digital sensor, it will only be 1.4cm long.
Canon macro lenses allow you to move in really close to your subject for a dramatic effect in the photograph. These types of lenses can be a great asset for any photographer. The dramatic effect that it creates enables you to add variety to your photos.

Prime Canon Wide-Angle Lenses

Canon wide-angle lenses are lenses with focal lengths below 50mm. The shorter the focal length, the wider the lens becomes and your field of view will be bigger. Simply put, if you stood in the same position, a Canon wide-angle lens can accurately squeeze more into the photo. This is particularly useful if you are trying to take a photograph of a large building from inside or out, an immense landscape view, or a group shot. These lenses are very useful when you cannot step back any further to take the photograph.

As you may expect, Canon wide-angle lenses have a greater distortion due to squeezing more into your photos. This distortion is especially evident toward the edges of the photo. On natural landscapes, this may not be that noticeable, but can appear unappealing on portrait shots unless the subject is placed directly in the middle of the frame. With that being said, this effect can produce pleasing results and be used to amplify perspective. I suggest getting as close to the foreground subject as possible so that it appears large in comparison to the background. Canon wide-angle lenses have large depths of field, which means that it is easier to get lots in well-defined focus from close-up to far away.

The most common wide-angle focal length that produces natural-looking results is the 28mm. In general, focal lengths below 20mm are known as ultra-wide-angle and can produce extreme results. I would have to say that the fish-eye lenses deliver the most extreme results as they produce a highly curved result, while capturing an extremely significant field of view.

When choosing a lens, it is important to keep in mind any reduction in field that would be caused by your DSLRs sensor. Canon’s APS-C models such as the EOS 400D/XTi and 40D both have a reduction factor of 1.6x. As a result, if you want 28mm equivalent coverage, you will need to fit them with an 18mm lens.
Canon wide-angle lenses can add a lot of enjoyment and provide methods to enhance your photo taking abilities in ways you have never experienced. So what are you waiting for? Pick up your Canon wide-angle lens today!

Varieties of Canon Wide Angle Lenses

Sooner or later, you will feel the need to purchase a wide angle lens. I suggest buying from Canon as they have an extensive selection! “Wide Angle” covers the approximate range of 14mm through 28mm. Any range that is longer than 28mm is really more of a general purpose lens. Anything that is shorter than 14mm would be considered a “fisheye” lens.

Canon EF28-105/3.5-4.5 USM

This is an eminent lens. It is minute, light and reasonably priced. This Canon wide angle lens covers a useful 28mm to 105mm range and the sharpness of your pictures will be exceptional. This camera takes 58mm filters which are a common size in the Canon lineup. If your finances are limited and you can only afford to purchase one lens, this is the Canon wide angle lens for you!

Canon 24/2.8

The 24/2.8 isn't a USM lens. It uses a micro motor which means you can hear it focus and you don't have full time manual focus. The advantage of the prime over the zooms is that it's smaller and lighter. What it does have is a floating element focus, which means that the optical formula of the lens changes when you close focus to maintain optimum sharpness by minimizing spherical aberration and field curvature. This can be a benefit if you do a lot of close-up photography work. A point to consider in this case would be the fact that the 24 prime lenses focus down to just below 10” while the 20-35/3.5-4.5 only focuses t0 13”. You may be thinking that 3” doesn’t sound like a lot, however for a wide angle lens used that close, it is substantial. The other major advantage of the prime ‘Canon wide angle lens’ is reduction in flare.

Canon 20-35/3.5-4.5 USM

This Canon wide angle lens is well constructed and an optimal performer when it comes to taking excellent photos. This lens has silent operation and full time manual focus allowing ease of use. This is probably the “best buy in the Canon wide angle lenses selection. The sharpness and flare control are exceptional and vignetting is negligible. This Canon wide angle lens is compatible and can be used with a standard Tiffen 77mm polarizer. The standard Canon filter size is 77 mm, so you may already have filters that fit this lens.

What to buy?

From a sharpness point of view, for landscape work where you are at f8-f16, I would chose a Canon wide angle lens that covered the focal length I wanted and had the features I wanted (filter size, weight etc.), with optical differences being a smaller weighting factor. If you intend to shoot a lot under flare provoking conditions though (e.g. with the sun in the frame), that's the time to give extra consideration to the prime lenses. Prime Canon wide angle lenses also typically show less distortion, though again, for landscape work, this isn't usually a big issue

Wide Angle Lenses vs. Telephoto Lenses - Which is better for you?

Can't decide between a Canon telephoto lens or a Canon wide angle lens?

Most professional photographers have learned about shorter focal length (wide angle lenses) and long focal length (telephoto lenses). There may be debates between different photographers as to which one is best but like everything it is all down to personal choice as to which one you like best.

Many of the experts out there may say that a wide angle length doesn't necessarily give you more depth of field. If you would like, you can always try this out for yourself. As an accomplished photographer, what impact will it have on your work?

Don't forget that this may only be true if you keep the size of the picture constant.

Remember that it is possible for you to take a picture of a subject using your Canon telephoto lens then zoom out and compare the difference with your Cannon wide angle lens. You might be thinking of taking a shot of some really amazing scenery, perhaps a hillside with beautifuly colored trees and sunlight shining down through the trees.

Try using the telephoto setting and zoom in, after which you can then zoom out and take a picture with the wide angle setting. When using the Canon wide angle lens, you will automatically expect there to be more depth of field in the last photo and that’s what it will look like. However, if you enlarge the photo, the depth of field may disappear. There are some of you who will zoom out to get more in their picture using only a wide angle setting. Remember though, by doing this, the objects may look smaller. When you zoom in on a particular object you want in your picture, you will typicaly lose depth of field. By zooming in and out and varying the focal length setting, you will have the perception that the depth of field is variable.

It may therefore appear that by using a wide angle lens you will get more depth of field if compared to using a telephoto lens. Remember that whatever a person is happy with when they are taking photographs is all down to the photographers personal choice as to what they like and know best and what they are looking for. What ever you decide to do, using either a Canon telephoto lens or a Canon wide angle lens should greatly enhance your photography experience.

How to use a Canon Wide Angle Lens

There is a very interesting feature that you can play around with when you are using a canon wide angle lens and that is the perspective stretching capability. What this is is the ability to things that that when looking through a wide angle lens, it may seem like the distance between the objects is much more than it really is. When looking at an object that is not very far away in the distance, it may appear that the object is much farther off than it is in reality. The object's proportions may increase dramatically; this effect can can make the object closest to the camera appear to be huge, and those farthest away seem to fade into the distance.

If you can imagine looking through a wide angle lens at two parallel lines stretching out away from the camera, the lines will merge at a distant point. This, for the wide angle lens, is called the perceptive vanish point. This means that at this distance the objects may represent a small point or cannot be seen at all. The normal lens camera can be farther away from the focal plane than for a wide angle lens.

As an example if you have two children who are similar in height, one may be nearer to the camera and the other may be a few feet farther away. Now you can take a photo with a wide angle lens, you will now see that the one who was farthest away looks a lot smaller when in fact they were of similar height. This will give you some perspective and effect you can achieve by using a wide angle lens understanding the stretching perspective.

There are a lot of benefits for a photographer when using a wide angle lens, as mentioned when there are two subjects, the one nearest the camera then becomes the primary subject. It is easy to assume this without additional thinking, and this happens when using a wide angle lens as it is much simpler to focus the viewer’s attention to the main subject.

5 Great Tips on Using a Wide Angle Lense!

5 Tips for Creative Photography Using Your Canon Wide Angle Lens

Here are some tips to help you achieve those fantastic photographs you are after using your canon wide angle lens.
This is a great way for you to add creativity to your photographs by capturing a wider field.

The subject may be the image's focus; however, by using this wide angle lens, you can make good use of the background in the picture to add interest. This way the picture will capture a larger story instead of just a photo; for example, in a picture of two children playing on the beach, you may have captured a small fishing boat going past in the background. In respects to the larger lens, the wide angle lens gives you a stronger depth of field. This is great in that it will not only give you a background and foreground, you also have the chance of keeping everything focused. However, on the other hand, if you were using a bigger lens then you would need to have the aperture more closed. This would mean you would have to use a slower shutter speed and a tripod, which is of course more time consuming. With all the extra messing around, the depth of field very well may not have the strenght it would have had you been using a wide angle lens. The great thing about using a wide angle lens is that if taking photo shoots of such things as railroad tracks, a jetty, fence-line things that may stretch into the distance, then by using a wide angle lens will actually give you great photos. This will give you a photograph where you may feel like you can actually walk right along the railroad track giving very strong lines to the picture. One cool thing you can create with a wide angle lens is the addition of a dimension which makes objects that are distant apear to be much further apart than they actually are. The objects at the forefront look smaller, while the background objects may seem a lot more distant. The tips I have provided shoud help you in some manner to acheive the goals you have set for yourself when it comes to creating fantastic pictures. There is nothing better than getting your camera and taking different photos using your wide angle lens and experimenting to see what sort of pictures you have taken.
