Heritage of superior imaging and optical performanceTAMRON's 90mm macro lenses have long been celebrated for their high resolution and beautiful bokeh. The new 90mm F2.8 MACRO lens, designed specifically for mirrorless cameras, reinforces this legacy via a rigorous optical simulation process during its development. This lens offers unparalleled resolution from the center to the edges, and delivers soft, velvety blurred bokeh and a three-dimensional effect that highlights the subject. The optical construction features 15 elements in 12 groups, including four special glass LD (Low Dispersion) lens elements that effectively suppress the tendency of light ray divergence and provide excellent correction for both spherical and chromatic aberration.The BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating significantly minimizes ghosting and flare, ensuring that even in backlit conditions, the finest details of the subject are captured with clarity and accuracy. Plus, this lens is highly corrected for superior flat-field resolution, ideal for flat subjects such as documents and coins, ensuring edge-to-edge sharpness and minimal distortion. This quality is especially important when shooting close-up images where depth of field is too shallow to neutralize the loss of sharpness that could otherwise occur at the extreme edges.This superb optical performance lets photographers explore unique photographic expressions across diverse photographic pursuits, not only for macro photography of flowers and insects but also for a wide variety of genres such as landscapes, portraits and snowflake photography.TAMRON's first 12-blade circular aperture for stunning circular bokeh and starburst effectsThis is TAMRON's first 12-blade circular aperture and will deliver a superb bokeh, with nearly a perfect circular aperture opening, when wide open. Also, the magnification ratio will perform 1:1 to 1:4 magnification at 0.23-0.49m (9.1-19.3in) focus range.The lens also suppresses vignetting in the four corners of the image. Composed entirely of bokeh-friendly spherical lens elements that minimize onion ring bokeh, this lens lets you to enjoy exquisite circular bokeh.In addition, the 12-blade design produces 12 rays for exquisite starburst effects when the aperture is stopped down, making it ideal for capturing dramatic scenes that include point-sources of light, such as birthday cake candles and evening cityscapes.Compact size, just 126.5mm (5in) in length for easy carryingThe 90mm F2.8 MACRO is a mid-telephoto macro lens with a maximum aperture of F2.8 and an overall length of 126.5mm (5in). With a maximum diameter of only 79.2mm, the lens fits comfortably in the palm of the hand and is easy to hold, making it compact enough to take everywhere. It's also light in weight at 630g (22.2oz), making it more pleasant to carry for long periods of time.New hood design with sliding window for easy filter rotationThis lens comes with a new type of lens hood featuring a sliding window for easy filter operation. The sliding window allows photographers to easily rotate filters without removing the hood, ensuring seamless adjustment and precise control over shooting conditions while maintaining the rhythm of normal camera operation.Compatible with TAMRON Lens Utility softwareThe 90mm F2.8 MACRO is compatible with the dedicated TAMRON Lens Utility software (for PC and Android OS) that was developed in-house by TAMRON. This software allows various lens and camera settings to be assigned to the Focus Set Button located on the lens. Also, the lens's firmware can be updated when necessary. TAMRON Lens Utility Mobile, which uses a smartphone, is especially useful for macro photography where a tripod is often used.New functions exclusive to the mobile version have also been added from this model. Users may customize functions of the lens or utilize unique features and enjoy various still photography and videography, thereby providing a more personalized and fulfilling shooting experience.MF Method:You can easily fine-tune your focus by adjusting the focus ring. Customizing the rotation angle of the focusing ring facilitates fine focusing in MF (in this case, it is possible to set a rotation angle up to 720-degree). In the micro world, where precision is paramount, manual focus adjustment is essential. By utilizing this function, you can make settings that are more delicate and suitable for you.A-B Focus:You can shift the focus back and forth between two preset focus positions that have been recorded beforehand. If you shoot video utilizing this function, moving the focus point creates movement in the image, allowing you to enjoy a macro view of the world that you would not normally be able to see.Capture must-get moments with high-speed, high-precision AFThe AF drive uses TAMRON's VXD (Voice-coil extreme-torque Drive) linear motor focus mechanism. This AF system allows comfortable focusing from the MOD through infinity with high-speed and high-precision performance that represents the highest level in TAMRON's history. A high degree of focus precision in steps of 0.005mm, less than one-tenth the width of a human hair. Tracking performance for moving objects is also outstanding, making it perfect for shooting subjects that move in unpredictable ways such as children and butterflies.These features ensure you can capture once-in-a-lifetime photos in sharp focus. In addition, because the quiet operation of the linear motor system is nearly silent, the lens can be used with confidence when shooting still images or video in quiet settings. This high-performance AF demonstrates its advantages and prowess in various types of macro photography situations.Highly convenient and easy to useFocus limiter switchThe lens is equipped with a focus limiter switch that can restrict the AF focus range, enabling faster focusing during AF shooting. This feature also helps prevent the lens from searching focus in full range when losing focus during close-range AF photography.Precise torque for accurate MF operationThe rotational torque of the focus ring has been carefully calibrated to assist precise MF operation. This moderate torque makes fine-tuning the focus more exact and ensures that the results are accurate.Overall lens design for user-friendly operationOur engineers carefully considered the structure and key parts right down to the fine details, resulting in an enhanced design that updates both operability and the ergonomic considerations. The surface of the lens exterior is shiny and glossy black. Improved abrasion resistance makes the lens harder to scratch and resists fingerprints. The material on the ring is also updated to have better grip performance with deeper grooves. The smoothly curved, glossy surface of the brand ring creates a dignified appearance with a design that signifies functional beauty and high quality.Supports camera key functionsTAMRON's 90mm F2.8 MACRO is compatible with many of the advanced features that are specific to mirrorless cameras.Nikon Z mount includes: Hybrid AF Eye AF M/A Mode In-camera lens correction (shading, chromatic aberration, distortion)BBAR-G2 Coating delivers stunning clarity and contrastTAMRON has long been an innovator of coating technologies that prevent ghosting and flare. Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR (Broad-Band Anti-Reflection) Coating. The coating corrects for ghosting and flare to an unprecedented extent and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.Moisture-Resistant Construction protects your lensFor greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment. Also, the Connector Port is the water-proofed USB Type-C variety.Circular ApertureA 12-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background highlights.Fluorine Coating for protection and safe cleaningThe front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture, and fingerprints.
