Tamron has announced two fixed focal length lenses – the Tamron SP 35mm F/1.8 Di VC USD & SP 45mm F/1.8 Di VC USD. These new lenses provide the ultimate in functionality and operation being equipped with fast f1.8 apertures together with Tamron’s renowned VC (Vibration Compensation) Image stabilization system. Both the SP45mm and SP35mm are compatible with full-frame DSLR cameras and APS-C format cameras.
Tamron SP 35mm F/1.8 Di VC USD & SP 45mm F/1.8 Di VC USD
The SP 35mm and SP45mm lenses will be launched and available from October 2015 in Canon & Nikon mounts. The launch date of the Sony mount is to be announced at a later date and will not include image stabilisation since this is provided in-camera.
The design philosophy of these new fast fixed focal length lenses opens a new chapter in the SP legend. Engineering processes and opto-mechanical construction have been totally integrated in the design process to create great feel to these lenses and deliver exceptional resolving power whilst reproducing fine details with subtle tonal gradations.
A fast F/1.8 aperture has been chosen to deliver more light to the viewfinder and sensor allowing use even in dim lighting conditions, with impressively smooth bokeh (background blur) when used wide open. This also allows an astonishingly short MOD (Minimum object distance) giving photographers a new opportunity to create stunning close focus images, even at the maximum F/1.8 aperture.
VC (Vibration Compensation) image stabilization also adds to the low light capability allowing photographers to enjoy the fast F/1.8 maximum aperture to the fullest extent, as well as assuring high quality images. Modern high pixel density sensors can also be more sensitive to minute vibrations that can cause the degradation of image quality, making VC an important feature to capture the best quality images.
Externally, the new design creates the best possible comfort and confidence under a product design philosophy of “Human Touch”. Metal-based barrel materials provide a pleasant feeling of comfort, high quality and durability, fitting firmly in the hands of the photographer.

1. Outstanding optical quality, even wide open
Even when used wide open at F/1.8 aperture, the lens design provides outstanding image quality with maximum aberration compensation, thanks to optimal use of sophisticated glass materials and highly advanced optical design
SP 35mm F/1.8 Di VC USD (Model F012) is a 10-element, 9-group construction, utilizing two molded glass aspherical elements, one LD (Low Dispersion) and one XLD (eXtra Low Dispersion) element
SP 45mm F/1.8 Di VC USD (Model F013) is a 10-element, 8-group construction, utilizing two molded glass aspherical elements and one LD (Low Dispersion) element.
Two of the aspherical elements effectively correct the field curvature to ensure planarity of the image plane, while efficiently compensating for spherical and comatic aberrations to achieve superb uniformity across the field with high-fidelity point spread reproducibility. Outstanding resolution is rendered from corner to corner and the sagittal comatic flare (a type of aberration that a point image at corners induces a comet tail-like blur), which tends to become prominently noticeable in night scenes, is corrected.
The LD elements and the XLD glass element (SP 35mm) optimally compensate for chromatic aberrations, which tend to become particularly prominent in fast-aperture lenses in general, and deliver crystal clear images without any residual color fringe.
2. Fast F/1.8 maximum aperture and integral VC (Vibration Compensation)
The desirable maximum aperture of F/1.8 was chosen as part of the very challenging design goals which included achieving superb optical performance, minimizing the closest shooting distance and integrating VC functionality while packaging those key attributes in a reasonably-sized barrel construction for better practical handling.
Repeated performance simulations were conducted throughout the entire design phase to assure achieving the essential, fundamental property of a fast-aperture lens in full-frame format, namely the harmony between excellent resolving power and beautifully-tuned background blur (bokeh).
The VC feature has become virtually indispensable in the era of high-pixel-density cameras. Freedom in handheld shooting at dusk or in a dimly lit room is dramatically expanded by cancelling the camera shake that often occurs under such low light conditions due to slower shutter speeds. Minute vibrations that plague cameras with high pixel count can also be well controlled to make the most of the sensor’s performance.
The SP 45mm lens is also the worlds first full-frame fixed focal length standard lens to be equipped with VC.
3. Best-in-class MOD (Minimum Object Distance) close-focusing capability
Since the lens allows for shooting at distances extremely close to the subject (similar to a macro), close-up pictures with spectacular background blur effect (bokeh) can
