This large aperture telephoto macro lens enables you to shoot up to 1:1 life size close-ups. Its large F2.8 aperture makes it an ideal lens for digital SLR as well as film SLR cameras. Two Special Low Dispersion (SLD) glass elements control various color aberrations and assure high image quality. Super Multi Coating gives superb color performance whilst cutting down flare and ghost. Its compact, yet advanced, construction has an overall length of Length 137mm (5.4in.), maximum diameter of 79.6mm (3.1in.), filter size of 72mm and weight of 895gr/31.6 ounces
F2.8 large aperture tele-macro lens
Tele macro lenses have a greater working distance. It is possible to enjoy Macro photography, even when you are far from subject. This enables you to capture the small animals and insects without disturbing them. Very narrow depth-of-field allows selective focusing and less distracting backgrounds. Large aperture of F2.8 is ideal for sports, action and indoor photography. It is equipped with two pieces of Special Low Dispersion (SLD) glass elements.
Two SLD glass elements control various color aberrations and assure high and sharp image quality.
Hyper Sonic Motor (HSM) with full time manual focus override.
The HSM models provide ultra quiet high-speed autofocusing as well as full-time manual focus override.
Floating Focusing System produces excellent optical performance.
A floating focusing system moves two different lens groups in the optical system to different positions. This system compensates for astigmatic aberration and spherical aberration. Since focusing does not change its overall length, this lens is easy to hold and use.
Super Multi Layer Coating
Super Multi Layer Coating of this lens gives superb color performance whilst cutting down flare and ghost caused by reflections from the digital image sensor.
Key Features
- APO (APO lens) - In order to attain the highest quality images, the APO lens has been made using special low-dispersion (SLD) glass and is designed to minimize color aberration.
- HSM (Hyper-Sonic Motor) - This lens uses a motor driven by ultrasonic waves to provide a quiet, highspeed AF.
- IF (Inner Focus) - To ensure stability in focusing, this lens moves the inner lens group or groups without changing the lens' physical length.
- CONV. (APO Teleconverter EX) - This lens can be used with the APO Teleconverter EX. It can increase the focal length and will interface with the camera's AE (automatic exposure) function.
- EX (EX Lens) - The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
- DG (DG Lens) - These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras whilst retaining suitability for traditional 35mm SLRs.
