If you own a Canon Digital Rebel or one of the Canon xxD digital SLR Cameras, the 18-200mm Canon Lens deserves a look from you. Its official name is Canon EF-S 18-200mm F3.5-5.6 IS telephoto lens. Quite a moniker, huh? The EF-S identification means that It is distinctively for what are known as “crop sensor” cameras. Also labeled as APS-C sensors. So, if you are shooting with a Canon 7D or one of the full frame models, the 18-200mm Canon lens will not even mount to your camera. Benefits of Owning a Super-Zoom Lens The evident main gain of owning one of these Super-Zoom lenses is that it may stay on your digital SLR almost constantly. This is an splendid vantage for travel and vacations when you don’t want to lug a camera bag or heavy backpack all over the countryside. It is also outstanding for getting quick shots. You do not have to stop and affix just the right lens to your camera body. Many times the shot is gone by the time you finish setting up to take it. In fact, having to alter lenses is one of the blessings AND the curses of digital SLR owners. We genuinely buy the cameras so we may alter the lens, then we are frustrated when we have to. Continuing with the benefits, this lens has a few more worth mention. First, as noted is the focal range, which is 11x. Considering the monumental variation in range, the effigy quality is exceptional. Also, there is IS (image stabilization) which is supposed to give you an further and added 4-stops of aperture without having to use a tripod. This is crucial because the widest aperture is only f/3.5, and it increments from there to a max of f/5.6. This is typical of the super-zoom lenses, whether Canon or a lot of other manufacturer. One more gain is the bokeh that is devised when using a wide aperture. Photographers are always comparing bokeh. Briefly, it is when you undertake to get the main subject of your photo in sharp focus and have the other areas of the photo in a pleasingly blurred focus. The 18-200 does a gorgeous good occupation with this, but it is not considered the best. The last gain has to do with a comparison to the “kit lenses” that Canon promotes. Sometimes new buyers buy the 18-55mm starter lens and an further and added 55-250mm lens for the mid-range focal lengths. These two lenses are not bad as far as effigy quality goes, but they are not high quality construction. The Canon 18-200mm lens is far better constructed than the kit lenses. The Down Side You will find this unfeigned of most super-zooms, whether they are Canon, Nikon, Sigma, or Tamron lenses. There is a compromise in effigy quality in order to get the wide focal range. Most will have barrel distortion at the wide angles and chromatic aberration issues at both the shortest and the longest focal lengths. This is not to say that the images are bad – the lens gives rise to genuinely good images. The problem areas are rather minimal, and you might not even observe them without someone pointing them out to you. But if you are looking for the pixel-perfect image, you will either need to recompense more cash or use a more specific focal length lens. Finally, consider a Canon look-alike. Third party manufacturers have devised a lot of genuinely good lenses that fit Canon digital SLR cameras. If the gains and problem areas are identical, why not consider saving a great deal of cash for one of those? It’s a thought. |
