The 18-200mm Canon Lens Does it All
Go to: Previous Article Next Article
In the event you own a Canon Digital Rebel or 1 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. Fairly a moniker, huh? The EF-S designation means that It's specifically for what are referred to as "crop sensor" cameras. Also labeled as APS-C sensors. So, if you're shooting with a Canon 7D or 1 of the full frame models, the 18-200mm Canon lens won't even mount to your camera.
Advantages of Owning a Super-Zoom Lens
The obvious primary benefit of owning 1 of these Super-Zoom lenses is that it can stay on your digital SLR virtually continually. This is an outstanding benefit for travel and vacations whenever you do not need to lug a camera bag or heavy backpack all over the countryside.
It's also terrific for obtaining fast shots. You don't need to stop and affix just the correct lens to your camera body. Lots of times the shot is gone by the time you finish setting up to take it.
Actually, having to change lenses is 1 of the blessings And also the curses of digital SLR owners. We truly purchase the cameras so we can change the lens, then we are frustrated when we need to.
Continuing with the advantages, this lens has a couple of much more worth mention.
Very first, as mentioned is the focal range, which is 11x. Considering the monumental variation in range, the image high quality is exceptional.
Also, there's IS (image stabilization) which is supposed to give you an extra 4-stops of aperture with out having to use a tripod. This is essential due to the fact the widest aperture is only f/3.5, and it increases from there to a max of f/5.6. This is typical of the super-zoom lenses, regardless of whether Canon or some other manufacturer.
1 much more benefit is the bokeh that's produced when utilizing a wide aperture. Photographers are constantly comparing bokeh. Briefly, it's whenever you attempt to get the major 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 pretty great job with this, however it just isn't considered the very best.
The last benefit has to do with a comparison to the "kit lenses" that Canon promotes. Occasionally new buyers buy the 18-55mm starter lens and an extra 55-250mm lens for the mid-range focal lengths. These two lenses aren't poor as far as image top quality goes, but they're not top quality construction.
The Canon 18-200mm lens is far much better constructed than the kit lenses.
The Down Side
You'll come across this true of most super-zooms, regardless of whether they're Canon, Nikon, Sigma, or Tamron lenses. There's a compromise in image top quality to be able to get the wide focal range. Most will have barrel distortion at the wide angles and chromatic aberration problems at both the shortest as well as the longest focal lengths.
This isn't to say that the images are poor - the lens produces definitely great images. The difficulty areas are fairly minimal, and you may not even notice them with out a person pointing them out to you. But if you're seeking the pixel-perfect image, you'll either have to pay a lot more funds or use a much more particular focal length lens.
Finally, think about a Canon look-alike.
Third party manufacturers have produced some genuinely very good lenses that fit Canon digital SLR cameras. If the advantages and difficulty areas are identical, why not take into consideration saving some dollars for 1 of those? It's a thought.
