The Tamron SP 45mm F/1.8 VC Lens is a premium normal prime lens design. With superior optical performance, class-leading close-up capability, and gorgeous rendering and resolution to match today's advanced camera systems with high pixel densities, it is the perfect everyday lens for digital SLR cameras.
Bright F/1.8 Aperture
An advanced optical formula ensures that this lens delivers high performance even shot wide open at F1.8 full aperture. Shoot highly resolving and ultra-sharp images with beautifully blurred backgrounds that help emphasise your subject - shallow depth of field portraits and isolated still life photos are a specialty of this premium glass.
Circular Aperture Blades
A 9-blade circular aperture ensures bokeh retains a circular shape throughout the aperture range.
Class-Leading Close Focus Capabilities
By using a floating system lens design, Tamron was able to optimise image quality by internally shifting elements to enable excellent image quality even when focusing at the ultra-close focus range of 29cm.
Superior Optical Design
Moulded glass aspherical elements help control field curvature across the lens plane and provide superb focusing uniformity with well corrected spherical and comatic aberrations. Using low dispersion (LD) glass further reduces unwanted aberrations and highlight fringing, giving excellent performance through the aperture range.
Coated Lens Elements
Ghosting and flare is reduced thanks to the special nano-structured eBAND (Extended Bandwidth and Angular-Dependency) and BBAR (Broad-Band Anti-Reflection) coatings applied to the lens surfaces.
Integrated Image Stabilisation
Integrated vibration compensation takes the low light photo and video capabilities of this lens even further. Shoot longer exposures hand held with reduced shake and vibration that remain clear in darker environments.
Quiet and Accurate Autofocus
Ultrasonic Silent Drive focus uses ultrasonic waves to deliver quiet, responsive and accurate autofocus every time. Where a photographer wishes to creatively apply or change focus, manual focus can be used at any time to override the AF module.
Moisture Resistant Construction
With a moisture resistant construction the SP 45 mm f/1.8 lens is designed to meet the needs of enthusiast and professional photographers who wish to shoot outdoors in adverse conditions. Fluorine coatings on the front element provide excellent resistance to moisture and smudges with only a quick wipe needed to keep the lens clean.
