Product description from Tamron
At launch 2005 Tamron wrote this regarding Tamron SP 11-18mm F4.5-5.6 Di-II :
"Di II: Lenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of our Di products. These lenses are not designed for conventional cameras and digital cameras with image sensors larger than 24mm x 16mm. This super wide-angle zoom lens, designed for exclusive use with digital SLR cameras using a sensor smaller than full frame, provides the extended focal length covering 17mm (when converted to 35mm format) that is desired by today´s advanced and pro photographers using digital SLRs. The lens features an entirely new optical system designed for optimal performance with digital SLR cameras."
Compatibility, autofocus and focal length
The lens is available for both Canon and Nikon cameras, but there are two different versions of this lens (one for each brand and mount) so it is important that you ask for and choose the right version when bying the lens.
This lens is designed and meant for Canon and Nikon 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.
Here it is the only Canon version of the lens that has a built-in autofocus (AF) motor. The possibility to use autofocus (AF) is available for Nikon cameras but only if the camera itself has a built-in autofocus (AF) motor. Some cheaper and budget camera models from Nikon lacks a built-in autofocus motor, and we at Lensora appreciate autofocus, so in the list of compatible cameras we have chosen to display only the cameras that you can get autofocus with.
The lens has a focal length of 11-18 mm. Since the lens is designed to be used on a camera with smaller sensor ('APS-C') the focal length will be equivalent to 18-29 mm if you have a Canon camera or 16-27 mm if you have a Niko camera.

Lens brightness and image stabilizer
The lens brightness and aperture value is f/4,5-5,6.
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 11 mm the lens brightness is f/4,5 and at 18 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 77 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.
Together with the lens there is a lens hood included but we have unfortunately no further information on model etc so feel free to contact us if you know more.
