NOTE: Vignetting occurs when pictures are taken with a Di
II
lens mounted on a full-size format SLRs camera
or a digital SLRs with a image sensor larger than 24 x 16mm.
Designed exclusively for digital cameras with APS-C size imagers.
Di
II
lenses are designed exclusively for digital SLRs with APS-C size imagers. This series of lenses are not
designed for 35mm fi lm cameras and digital SLR cameras with image sensors larger than 24 x 16mm.

NOTE: The angles of view obtained by a “Di” lens mounted on a digital camera with smaller-size imagers dif-
fer from those obtained by the same lens mounted on a full-size format SLRs.
Digitally integrated design.
Di lenses are designed to fi t the characteristics of digital cameras as well as fi lm cameras by paying attention to
countermeasures against ghosting and fl are through such advances as special coatings.

Since the size of 35mm fi lm format is
larger than the image sensor general-
ly used in D-SLRs, a digital camera
captures a narrower angle of view
than a 35mm fi lm camera even at the
same focal length settings. Tamron's
Di-II lenses, made exclusively for digi-
tal SLR cameras, provide ideal focal
lengths to cover the range desired by
D-SLR shooters.

Attempts to design shorter focal lengths inevitably result in
a larger lens diameter. Tamron has solved this problem by
designing the size of the lens’ image circle to match 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 fi lm format.
*When pictures are taken with a Di
II
lens mounted on a
35mm fi lm camera, image corners become dark (ie., vignet-
ting becomes noticeable).
