Pentax smc DA 17-70mm f/4 AL (IF) SDM

Pentax smc DA 17-70mm f/4 AL (IF) SDM lens
 

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.

 

Not stabilized

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.
