11.1 \r\n high zoom ratio lens is designed exclusively for \r\n digital SLR cameras and incorporates Sigma’s \r\n original OS (Optical Stabilizer) technology. \r\n

\r\n

MSRP: \r\n $820.00

\r\n

This high ratio zoom lens is \r\n incorporated with Sigma’s original OS (Optical \r\n Stabilizer) function and exclusively designed \r\n for digital SLR cameras. It is perfectly \r\n suitable for low light conditions, indoors, at \r\n dusk and telephoto range. SLD (Special Low \r\n Dispersion) glass and aspherical glass provide \r\n excellent correction for all types of \r\n aberrations. This lens has a minimum focusing \r\n distance of 45cm (17.7”) throughout the entire \r\n zoom range and has a maximum magnification of \r\n 1:3.9. The inner focusing system is suitable for \r\n using a petal-type lens hood supplied and also \r\n circular polarizing filters.

\r\n\r\n

Sigma’s own unique \r\n technology OS (Optical Stabilizer) \r\n function
The 18-200mm f3.5-5.6 OS is \r\n equipped with Sigma’s own very special OS (Optical \r\n Stabilizer) technology.? This system uses \r\n two sensors inside the lens to detect vertical \r\n and horizontal movement of the camera by moving \r\n an optical image stabilizing lens group, to \r\n effectively compensate for camera shake.? \r\n It also automatically detects movement of the \r\n camera and compensate for camera shake when \r\n shooting moving subjects such as motor \r\n sports.

\r\n

Excellent Optical \r\n Performance
A Special Low Dispersion \r\n (SLD) lens and three aspherical glass elements \r\n provide excellent correction for all types of \r\n aberrations and produce a high level of optical \r\n performance throughout the entire zoom \r\n range.? The super multi-layer lens coating \r\n reduces flare and ghosting while producing the \r\n ideal color balance.

\r\n

Enables close-up \r\n photography
This lens has a minimum \r\n focusing distance of 45cm through entire zoom \r\n range with a maximum magnification of 1:5.3 \r\n making it very convenient for taking close-up \r\n photos.

\r\n\r\n

Inner focusing \r\n system
Because the front of the lens \r\n does not rotate, circular polarizing filters and \r\n petal-type hood can easily be used.

\r\n

Magnification scale \r\n
A magnification scale is displayed on the \r\n lens barrel, ensuring ease of use.

\r\n

Zoom lock switch \r\n mechanism
A zoom lock switch mechanism \r\n is provided to prevent the lens from creeping \r\n due to its own weight.

\r\n

Corresponding AF \r\n Mounts
This lens is available for \r\n Canon, Nikon and Sigma mounts. Canon mount is \r\n available now, Nikon and Sigma will be available \r\n in the near future.

*Vignetting will occur if \r\n the lens is used on digital cameras with image \r\n sensors larger than APS-C size or 35mm SLR \r\n cameras.\r\n\r\n

If you would like to know more about the subject - then you will want to read this article. It includes plenty of information about this subject that is sure to help you better understand the ins and outs that seem to confuse most people. It really does not have to be difficult to understand.

The information that follows is one way to look at this information, and after reading the article you are free to form your own opinion. Whether or not you agree with the subject matter is up to you, and you are certainly free to make up your own mind about the material presented here.

In Digital photography there are still only three basic things to worry about in regards to your camera. These are: the aperture (also called F-stop), the shutter speed, and the pixels. The difference here\’s that newer cameras, both digital and non digital alike have simplified things. You do not usually see the actual F-stops or Shutter speeds, but the photos they left behind still control the same things.\r\n\r\n

Shooting the Minds Eye


Are you finding the information on the subject confusing? Perhaps you are finding much of the information contradictory? If so, you are not alone. That's the reason why we developed our website. We spent time trying to gather the facts for ourselves, unfortunately, what we found didn't help us make decisions at all.

Have a look at the article below. It presents the facts in such an easy language that we were able to understand it immediately. If it helps clear the fog for you, please let your friends know about our website, as it might be useful for them also.

To correct what I said earlier; grandpa might have actually been satisfied with a snapshot from a point and shoot camera. Both mother and father would look at that picture and feel something just was not right. It\’s not that his picture was a bad picture; it just did not match what they\’d in mind. By using depth of field you can make people see what you saw, not only with your natural eyes, but in your mind\’s eye too.\r\n\r\n
