SP 45mm F/1.8 Di VC USD

Tamron has announced two fast premium fixed focal length lenses featuring new external lens appearance and branding. 

The SP 35mm and 45mm f/1.8 Di VC USD lenses are both compatible with full frame DSLR and APS-C format cameras. The SP 35mm has best-in-class MOD (Minimum Object Distance) close-focusing capability, measuring just 0.2m (7,9"), yielding a magnification ratio of 1:2.5, the shortest close-focusing capacity among fast-aperture fixed focal lenses in full-frame format. 

Tamron say both lenses produce a spectacular bokeh effect, thanks to circular aperture blades, expanding the scope of photo opportunities. 

The SP 35mm f/1.8 Di VC USD is a standard wide-angle lens that provides an equivalent focal length of 54mm on APS-C cameras.

The 45mm f/1.8 Di VC USD is the first high-speed fixed focal standard lens in full-frame format with VC (Vibration Compensation), and offers a unique perspective with significantly shorter minimum focusing distance.

SP 35mm F/1.8 Di VC USD

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. 

No pricing has been announced as yet, but both lenses will be available in Nikon and Canon mount from October 2015. The launch date of the Sony A mount will be announced later on. 


Tamron SP 35mm and 45mm f/1.8 Di VC USD Key Features:

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.

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 canceling 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.

Best-in-class MOD (Minimum Object Distance) close-focusing capability 

SP 35mm

MOD measures just 0.2m (7.9”), yielding a magnification ratio of 1:2.5, the shortest close focusing capability among fast-aperture fixed focal lenses in full-frame format*. 

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 be obtained with the aperture wide open, thereby expanding the scope of photo opportunities. Tamron’s proprietary Floating System, which places a group of elements at the optimal location as the focusing group travels relative to shooting distances, ensures the best imaging performance at any range. From the closest distance right through the focal range, image quality is excellent.

* Rated top among current 35mm fixed focal length interchangeable AF lenses for full-frame DSLR cameras excluding macro lenses (as of July 2015; Tamron).

SP 45mm

MOD measures 0.29m (11.4”), yielding a magnification ratio of 1:3.4, the best-in-the-class close focusing capability among fast-aperture fixed focal lenses in full-frame format**.

** Rated top among current 45mm and 50mm fixed focal length interchangeable AF lenses for full-frame DSLR cameras excluding macro lenses (as of July 2015; Tamron).

Optimal relative illumination means no dark corners

Some fast-aperture lenses “vignette” or have darkened corners due to uneven light distribution, especially wide open. However, even at the full open aperture, the overall illumination level across the entire field is well balanced and optimized. 

eBAND Coating deployed to thoroughly suppress ghosting and flare

eBAND (Extended Bandwidth & Angular-Dependency) and BBAR (Broad-Band Anti-Reflection) coatings, both providing outstanding anti-reflection effect, are applied to critical element surfaces for maximum light transmission. Internal reflections from element surfaces which cause ghosting and flare are reduced to an absolute minimum. Flawless, crystal clear images can be obtained. 

eBAND Coating, a hybrid nano-structured layer with extremely low refractive index coupled with multi-layered anti-reflection coating technology, efficiently minimizes reflection of extremely angulated incident light—something that cannot be achieved by conventional anti-reflection coatings alone.

High-speed AF with USD (Ultrasonic Silent Drive)

Fast, quiet AF is achieved by employing a USD ring-type ultrasonic motor which enables remarkably precise focusing drive with high torque and responsiveness. Because the rotational torque of the USD is generated by waves of ultrasonic vibrations, inherent operating noise is extremely low and practically unnoticeable. In addition, Full-time Manual Focus override is available at any point during the autofocus operation for deliberately shifting focus without switching the AF-MF mode back and forth.

Fluorine coating on the front element repels water and fingerprints

Fluorine coating technology, developed for use in industrial optics applications, has been adapted to photographic lenses. The water and oil repellant coating applied to the front element surface allows instant removal of dirt or smudges with ease. The coating also provides a reasonable level of durability, and will sustain its effectiveness for years.

Moisture-resistant construction 

Seals are located at the lens mount area and other critical locations to prevent infiltration of moisture and/or rain drops and provide moisture-resistant construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions.

Circular aperture for enhanced bokeh

The 9-blade diaphragm retains a nearly circular opening even when stopped down by two stops. Marvelously tuned blur in the subject background can be obtained without generating undesirable shapes of aperture patterns.

Interesting development and good to see Tamron moving back into prime lenses. If the images live up to the hype then they should be challenging Sigma and the OEMs.

Sad to see no DoF markings though - even in this day and age they are useful for quick hyperfocal working.

Not sure about the design though. Bland bordering on dull springs to mind...

To me they look very clean - I don't need (or want) flashy looking lenses, just a good quality result.

I'll be watching these to see how they work out, especially the 35mm

Will be interesting to see the price point, especially now that Canon have the 50mm 1.8 MKIII. To compete with that, even though the Tamron has VC, will be the challenge. That said though, I use Tamron and Canon glass and find Tamron's pro range sits above Canon's standard range, and in some areas very, very close to L glass quality. I suspect this 45mm will be better than Canon's 50mm if their other lenses are anything to go by. The 35mm looks like it could be a winner too. I'm looking forward to seeing some reviews.
