Sony DT 18-135mm F3.5-5.6 SAM Review

Sony DT 18-135mm F3.5-5.6 SAM

General information

This is a zoom lens manufactured by Sony and the lens was released 2012.
The lens belongs to the category superzoom lenses. A superzoom lens gives you a wide zoom range, from a wider field of view (wide angle) to a more narrow field of view (telephoto) and is usually appreciated as an all-in-one travel lens.

Compatibility, autofocus and focal length

This lens is designed and meant for  cameras with a smaller sensor (often referred to as 'APS-C') which means that the lens does not fit all camera models. By clicking on the link below you can make sure that the lens works with your camera model and you should do an additional check with your local dealer as well, before you buy the lens just to be sure.

The ability to use autofocus is available for all cameras.

The lens has a focal length of 18-135 mm. Since the lens is designed to be used on a camera with smaller sensor ('APS-C') the focal length will be equivalent to 

Lens brightness and image stabilizer

The lens brightness and aperture value is f/3,5-5,6.

This lens is not considered to have a good aperture value and brightness. It is something to consider before you purchase the lens. To compensate for this you might, while photographing in less favorable light conditions, be forced to either use higher ISO settings (which generates more noise in the image), slower shutter speeds (which may give some motion blur) or flash lightning. Read more at the link below what lens brightness means to you as a photographer.

One thing to consider is that the lens has a variable brightness, which means that depending on how much you are zooming the lens will have a different maximum aperture value. At 18 mm the lens brightness is f/3,5 and at 135 mm the brightness is f/5,6. Through the link below you can read more about what this could mean for you as a photographer.

The lens lacks image stabilization, which otherwise os good for avoiding the blur that can occur when using slow shutter speeds. 

Filter and Lens Hood

The lens has a traditional filter thread on the front and its measuring 62 mm which also the filter you will use must have. If you use for example an UV filter can be a cheap insurance against scratches and dust.

There is a lens hood that fits the lens (model name "SH0008") but unfortunately this is something that is not included when purchasing the lens and must be ordered and bought separately, as an accessory.
