Tamron Lens Codes

When you see a price list for a lens or even get the lens it is covered in different types of codes which is supposed to give you information about the lens, but do you know what they all stand for. What we have done here is list out the codes we have been able to identify with their descriptions in order to give you a quick look up list when researching lenses.

Nikon D40, D40x and D60 cameras do not have a mechanical drive to focus lenses, so only lenses that contain an electronic focusing motors will work with these cameras. On the Tamron Lens Price comparison page we have highlighted those lenses that will work with these cameras.

For example: AF 28-300mm f3.5-6.3 XR Di VC LD Aspherical [IF] MACRO

28-300 is the zoom length from 28mm to 300mm

f3.5-6.3 is the aperture range where it is f3.5 at 28mm and f6.3 at 300mm

The codes below explain all the other letters XR Di VC LD Aspherical [IF] MACRO

AD A lens with Anomalous Dispersion element(s), a special optical glass which delivery large partial dispersion ratios relative to a specific light wavelength zone.
AF Autofocus
ASL Aspherical Lens Elements. A type of lenses that virtually eliminates the problem of coma and other types of lens aberration. The are particularly good at correcting distortion in wide-angle lenses as well as contributing to a lighter and smaller lens design.
Di Digitally Integrated Design.  Optical system designed to meet the performance characteristics of DSLR cameras as well as film cameras. Lenses can be used with either Digital or Film SLR cameras.
Di II Digitally Integrated Design. Lenses made exclusively for digital SLR cameras with image sensors smaller than 24mm x 16mm (APS-C). Features high resolution performance incorporating anti-reflection coating and optical configurations to compensate for internal reflections and ghosting. Peripheral light fall off, more noticeable with digital cameras, is also reduced. Also provide ideal focal lengths to cover the range desired by DSLR users. Not designed for Full Frame Digital SLR cameras.
HID High Index High Dispersion Glass element. Minimises on-axis and lateral chromatic aberrations.
IF Inner Focus. The lens is able to focus without physically changing its size, where optical movement is limited to the interior of the non-extending part of the lens barrel, allowing for a more compact and lightweight lens as well as closer focusing distances.
LAH LD Hybrid aspherical elements.
LD Low Dispersion elements which effectively compensate for chromatic aberration that is a problem at the telephoto end and lateral aberration at the wide angle end.
MACRO Used on those lenses which have the ability to be used for close up (macro) photography. Tamron puts MACRO on those lenses that provides a magnification ration of 1:4 or greater, indicating it is capable of providing macro results.
SP Super Performance. High performance Specifications. The first priority in producing these lenses have been superior specifications and outstanding performance free from cost restraints.
VC Vibration Compensation. Uses a 3 coil system allowing lenses to remain compact in size. Gives smooth and steady images in the viewfinder.
XR Hi Refraction index glass elements resulting in minimum aberration. Allows smaller lens diameters while maintaining aperture values for overall compactness.
ZL Zoom lock mechanism. Prevents undesired barrel extension whilst carrying the camera-lens around, thus protecting the lens.

If you come across any other abbreviations then please let us know so that we can research their meanings and extend the above list.
