About Sony 18-135mm

Sony 18-135mm f/3.5-5.6 SAM AF/DMF Zoom Lens was developed to provide the most ideal focal range for normal use covering frequently-used focal lengths between 18mm and 135mm.

The Sony SAL18135 mid-range zoom lens enables rich expression for a wide range of shots. Direct Manual Focus (DMF) allows you to switch between AF and MF without removing your eyes from the viewfinder to seize fleeting photo ops with ease. Plus, enjoy smooth and quiet AF thanks to the Smooth Autofocus Motor (SAM), which also improves AF response when shooting moving subjects. And with a single ED glass lens element as well as a pair of aspherical lens elements, the SAL18135 delivers images with low levels of color aberration for excellent image quality in any setting.

New Direct Manual Focus mechanism
DMF (Direct Manual Focus) functions previously offered mainly on Carl Zeiss, G and other high-performance lenses are included with the SAL18135. DMF allows users to quickly switch between AF (autofocus) and MF (manual focus) without removing their eyes from the viewfinder to easily seize fleeting photo opportunities with success.

Comfortably light mid-range zoom lens
The SAL-18135 reduced weigh of 14 oz./398 grams makes it easy to shoot while also finding ways to enhance the shooting experience. Its weight was especially reduced in the front of the lens to improve overall balance and make it easier to hold the camera steady when taking photos.

Silent, high-speed AF drive via SAM
The Auto Focus drive in the SAL is smooth and quiet thanks to its SAM (Smooth Autofocus Motor), which also helps improves AF response when shooting moving subjects. Reductions in drive noise also make the SAL-18135 quieter than other entry-level model lenses in the line-up.

Superior internal optics including ED glass
Featuring a single ED (Extra-low Dispersion) glass lens element as well as a pair of aspherical lens elements, the SAL-18135 delivers images with low levels of color aberration. The result is excellent image quality that ranges from indoor photo birthday parties to as stunning landscapes.

Very sharp pictures


from Hamden, CT  -  Photo Enthusiast

Very quick and quiet autofocus. Pictures are much sharper than my older Minolta 28-85. Not sure how much of that is due to the 'compensation' performed by the camera for the newer lenses. There is a lock switch, but for some silly reason it only engages at 18mm zoom. I guess it's purpose is to prevent lens creep, but it would be nice if it worked at all focal lengths. The one really big negative is that when the lens hood is on backwards (when you don't need it), it covers most of the zoom ring. You've got to fight around the hood to reach the zoom ring. It's only held on with 1/4 turn, so it's easy to knock loose by accident. I'll need to get into the habit of flipping it back and forth a lot.

Questions about this item:

JEFF K  I believe the 28-135 being referred to is a Minolta branded full frame lens now discontinued and only available on the used market. The 18-135mm Sony lens is designed for APS-C cameras only. On APS-C cameras the 18mm length provides a great wide angle view.
Shopper  Isn't this a new lens to be released in mid-July?
RICHARD G  It has been released and is available at several sites.
