Angle of ViewThe range across the film surface onto which the subject is exposed isexpressed as an angle, called the angle of view. Wide-angle lenses withtheir short focal lengths have a wide angle of view, which means theexposure range is wide. Conversely, telephoto lenses, which have long focallengths, have a narrow angle of view, making the exposure range narrow.So a wide-angle lens is used to take a wide area of a subject nearby whereasa telephoto lens is used to take only part of a subject located further away.A single zoom lens, meanwhile, can function as a number of lenses withdifferent focal lengths, enabling you to smoothly alter the angle of viewand quickly frame the shot. You can select your lens to create the effect ofdistance or depth of field, or to suit the location and surrounding conditions.Some Examples of Effective Focal Length inRelation to Sensor SizeFull Frame SensorCanon EOS 1DX, 1DX Mark II5D, 5D Mark II, 5D Mark III5Ds, 5Ds R, 6D, 1Ds Mark IIINikon D4, D5, DfD610,D750,D800,D810,D810ASONY α7S II, α7R II, α7 IIα7S, α7R, α7APS-H Size Sensor(1.3x Full Frame Sensor)EOS 1D Mark II,1D Mark IIn,1D Mark IIIAPS-C Size Sensor(1.6x Full Frame Sensor)Canon EOS 40D,50D,60D,70D 80D7D,7D Mark II, M, M2, M3Rebel T4i,T3i, 0D,1200D,1300DAPS-C Size Sensor(1.5x Full Frame Sensor)Nikon D40, D60, D90, D300D3000, D5000, D7000, D500,D7200, D5500, D5300, D3300SONY a57, a65, a77, α6300,α6000, α5100, α5000Depth of FieldPerspectiveWhen you focus on a subject, there is part of the subject that is in focusand parts in front and behind which are not in focus. This range in whichthe object is seen to be sharply in focus is called the depth of field.Perspective is the visual effect of moving a subject which is in theforeground closer to or further from the background. If you takephotographs with lenses of different focal length while keeping the sizeof the subject in the foreground constant, the background appears to befurther away and the sense of perspective is exaggerated with a shortfocal length wide angle lens.If the focal length is kept the same, the depth of field gets deeper (therange in which the subject is sharp gets wider) as the aperture is stoppeddown, and it gets shallower (the range in which the subject is sharp getsnarrower) as the aperture is opened.Even when the aperture stop is the same, the depth of field getsshallower as the subject distance gets shorter, and deeper as the subjectgets further away. Furthermore the depth of field is deeper with a shortfocal length wide angle lens, and shallower with a long focal lengthtelephoto lens.With a long focal length telephoto lens, the background appears to becloser to the subject and the sense of perspective is lessened. You cangreatly change the feeling of presence even with the same subject byusing this sense of perspective.Micro Four Thirds Size Sensor(2x Full Frame Sensor)Olympus PEN E-P3, E-P4, E-P5E-PL3,E-PL4,E-PL5,E-PL6,E-PL7E-PM1,OM-D E-M5,OM-D E-M10Panasonic Lumix GH2,GH3,GH4GX8,GX7MK2,G7,GF7,GM5,GM1S25

Superior use of filters as the front filter thread does not rotateFilter Size (mm)The internal focusing system has a number of advantages, including:Diaphragm BladesThe two main methods of lens focusing are either the completestraight forward movement of elements (used mainly with single focallength lenses), or the rotation of the entire front lens barrel group(used mainly with zoom lenses). The internal focusing system usedby Tokina moves each lens group, but does not change the overalllength of the lens - this is especially useful with telephoto designs.Aperture RangeInternal Focus SystemClosest Focus Distancefrom Film Plane(in Macro Mode)Manual FocusDiagonalAngle of ViewAuto FocusStandard lenses are made from a combination of spherical lens elements.However, there can be problems with such lenses when light enteringat the edges of the lens may not be perfectly focused at the same pointas light entering at the center. That presents limits to performance inwide aperture and super wide-angle lenses.Tokina uses asphericalglass elements in many of its lenses. In addition to correcting sphericalaberration, these lenses fully correct light quantity and distortion at theedge of the image and provide excellent results when used in combinationwith floating elements. Through technical cooperation with Hoya, Tokinahas succeeded in producing high quality molded glass elements witha greater aspherical shape than any other lens so far. This technique isunparalleled in its technological sophistication and excellence.Optical ConstructionElements / GroupsThe newly improved one-touch focus clutch allows the focus to bemoved quickly and easily from the AF position back into the MF position.In Nikon and Canon mounts, the lens can be set for manual focusingwithout an AF/MF switch or setting the body to the AF position.Aspherical OpticsMountOne-Touch Focus Clutch MechanismTECHNICAL SPECIFICATIONSLensTECHNOLOGY - MECHANICAL107.5 8994.5600BH-821f/2.8 f/329557395.1490BH-5511:8.36f/2 f/2298289106735BH-8230.28m (11 in.)1:8.62f/2.8 f/229828992560BH-821104 82 0.3m (11.8 in.)1:11.6f/2.8 f/229778489.2550BH-77B10/8180 100 0.14m (5.5 in.)1:2.56f/3.5 f/226N/A7071.1350Built-in10/8180 100 0.14m (5.5 in.)1:2.56f/3.5 f/226N/A69.970.9350N/An The external appearance and specifications shown in this catalog may bechanged without any advance notice.n Mount C: CANON AF N/D: NIKON AF-D S: SONY-An 1g 0.03527 oz n 10mm 0.39370 inch n 1m 3.28084 feet27
