APS-C sized image

Lenses that create APS-C sized image are designed for digital only. They cannot be used on cameras that have image sensor larger than the APS-C format. These lenses are not suitable for film cameras either.

 

Ultrasonic AF

Lenses with ultrasonic focusing mechanism tend to be quiter and faster than traditionally focusing lenses.

 

No stepping motor AF

Lenses with stepping motor focusing mechanism are better for contrast based focusing, and are quiter and faster than traditionally focusing lenses.

 

One or more Low Dispersion lens element is used

Low Dispersion lens elements help to reduce chromatic aberration.

 

Built-in image stabilizer

Image stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule.

 

Metal mount

Cheaper lenses are usually equipped with plastic mount, while more expensive, professional lenses have metal mount. In general, metal mounts are more durable, and a good thing to have when lenses are changed a lot. When a camera is used mainly with one lens, the material of the lens mount is not that important.

 

Internal Focusing

Internally focusing lenses don't change their size while setting focus.

 

No Internal Zoom

Internally zooming lenses don't change their size while focal length is changing.

 

The front lens is fixed

The fixed front lens is not rotating during zoom and/or focusing. This allows the photographer to use petal shaped lens hood. Fixed front lenses also make the use of polarization filters a lot easier.

18-250mm F3.5-6.3 DC OS HSM incorporates Sigma's original anti-shake compensation function, with a 13.8 times zoom ratio. As opposed to having an anti-shake function in the camera body, this lens’s Hybrid Optical Stabilizer provides not only an anti-shake function for the camera body, but also compensates for image shaking in the view finder as the Optical Stabilizer is built in to the lens. Incorporating four Special Low Dispersion glass elements and three aspherical lens elements provides excellent image quality throughout the entire zoom range. This lens has a minimum focusing distance of 45cm (17.7 inches) at all focal lengths and a maximum magnification of 1: 3.4 reproduction ratio, making it ideal for close-up photography. An inner focusing system eliminates front lens rotation, making it suitable for use with circular polarizing filters and the supplied petal-type hood. Incorporating super multi layer coating reduce the ghost in the backlight photography.
