camera lenses 101 - Sigma 18-200mm

Sigma 18-200mm f/3.5-6.3 DC AF OS (Optical Stabilizer) Zoom Lens for Canon Digital SLR Cameras

Sigma 18-200mm f/3.5-6.3 DC AF OS (Optical Stabilizer) Zoom Lens for Canon Digital SLR Cameras

Sigma’s own unique technology OS (Optical Stabilizer) function
The 18-200mm f3.5-6.3 OS is equipped with Sigma’s own unique OS (Optical Stabilizer) technology. This system uses two sensors inside the lens to detect vertical and horizontal movement of the camera by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It also automatically detects panning movement of the camera and compensate for camera shake when shooting moving subjects such as motor sports.
Excellent Optical Performance
A Special Low Dispersion (SLD) lens and three aspherical glass elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range. The super multi-layer lens coating reduces flare and ghosting while producing the best color balance.
Enables close-up photography
This lens has a minimum focusing distance of 45cm through entire zoom range with a maximum magnification of 1:3.9 making it very convenient for taking close-up pictures.
Inner focusing system
Because the front of the lens does not rotate, circular polarizing filters and a petal-type hood can easily be used.
Magnification scale
A magnification scale is displayed on the lens barrel, ensuring ease of use.
Zoom lock switch mechanism
A zoom lock switch mechanism is provided to prevent the lens from creeping due to its own weight.

The Sigma 18-200mm high-zoom-ratio lens is designed exclusively for Canon digital SLR cameras and is capable of covering a wide range of focal lengths, from wide-angle to telephoto. Two Special Low Dispersion (SLD) glass elements and two hybrid aspherical lenses correct for all types of aberrations, letting Sigma house the extended-range super-zoom lens in a compact and lightweight body that measures 70mm in diameter and 78.1mm long and weighs a mere 14.3 ounces. The new lens coating, meanwhile, reduces flare and ghost--a common problem shared by many digital cameras--while also creating an optimum color balance. Other details include a minimum focusing distance of 45cm (17.7) at all focal lengths, a high zoom ratio of 11:1, and a maximum magnification of 1:4.4.
The lens design incorporates an inner focusing system that prevents the front of the lens from rotating, making it particularly suitable for using circular polarizing filters and petal-shaped lens hoods. In addition, the overall length of the lens never changes during focusing, making the lens convenient to handle and easy to use. Finally, the lens's zoom lock switch eliminates "zoom creep" during transport--a convenient addition when traveling. The lens, which includes a metal mount, is backed by a one-year warranty.

11/365: Minolta SRT 101

This is the camera I used for my film class this semester.
I bought it off an older gentleman who had placed an ad on Craigslist.
It cost me $50 with 4 lenses and a flash.
Damn good deal!

The reason I took a picture of it was because today was the last day of the semester to go use the photo lab at school.
In a way, it's a tribute to this semester which is almost over.
I made my final prints yesterday because today would be madness with people trying to finish final projects and making prints to submit to the San Diego County Fair.

Taken on my Sony a200.

Soooo I kinda got a new-used camera with two awesome-tastic lenses yesterday. I already managed to use a roll of film, and I shall get it developed some time later when I have actual money.

Anyways, I can check 'touch a Minolta camera' & 'Own an SLR camera' off my bucket list.

Sigma 50-200mm f/4.0-5.6 DC IF SLD Optical Stabilized (OS) Lens with Hyper Sonic Motor (HSM) for Canon Digital SLR Cameras

This compact high-performance telephoto zoom lens incorporates Sigma’s own Optical Stabilizer function. The lens incorporates SLD (Special Low Dispersion) glass in the front lens groups and is equipped with an inner focusing system to provide high image quality throughout the entire zoom range. The incorporation of HSM (Hyper-Sonic Motor) ensures quiet and high-speed auto focus. The OS (Optical Stabilizer) function effectively eliminates the effects of camera shake so subjects can be easily and clearly seen in the viewfinder as well as in the image. It allows the use of shutter speeds up to 4 stops slower than normal for steady, handheld photography. For Sony and Pentax mounts the built-in OS System allows the photographer to see the stabilized image in the viewfinder and can be used as an alternative with cameras having built-in image stabilization. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images throughout the entire zoom range. This lens has a minimum focusing distance of 43.3inches (110cm) throughout the entire zoom range and a maximum magnification ratio of 1:4.5. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters.
