Samyang 21mm T/1.5 ED AS UMC CS

Samyang 21mm T/1.5 ED AS UMC CS lens
 

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.

 

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.

 

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.

 

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.
