The Tamron SPAF10-24mm f/3.5 -4.5 Di II is an ultra wide-angle zoom lens designed for exclusive use on digital SLR cameras with smaller-size imagers. Boasting a focal length range of 10 - 24mm (the 35mm equivalent of a 16mm to 37mm, this lens has a varied range of applications for creating dramatic images as it features both ultra-wide and semi-wide angle settings.
The close focusing capability of this lens enables image capture with an exaggerated perspective at the 10mm ultra wide-angle end or with a maximum magnification ratio of 1:5 at the 24mm semi-wide-angle setting.
• Captures Ideal Range of Focal Lengths With D-SLRs
Since the size of 35mm film format is larger than the image sensor generally used in D-SLRs, a digital camera captures a narrower angle of view than a 35mm film camera even at the same focal length settings. This lens, made exclusively for digital SLR cameras, provides ideal focal lengths to cover the range desired by D-SLR shooters.
• Fits Smaller-Size Imagers
This lens is designed so the size of the lens' image circle matches that of smaller-size image sensors. In the compact design, it is almost comparable to a lens offering the same angles of view in 35mm film format.
Please Note:
When pictures are taken with a Di-II lens mounted on a 35mm film camera, image corners become dark (ie., vignetting becomes noticeable).
• Aspherical Lens Elements
The optical system within this zoom lens uses three large-aperture glass-molded aspherical lenses, as well as three hybrid aspherical lenses, which minimize spherical aberrations, coma, and distortion.
• Minimum Focusing Distance Across Zoom Range
The close focusing capability of this lens enables the capturing images with an exaggerated perspective at the 10mm ultra wide-angle end or shoot with a maximum magnification ratio of 1:5 at the 24mm semi-wide-angle setting with the freedom to create closeups at the minimum focusing distance of 0.24m throughout the zoom range.
