TAMRON 90mm F2.8 Di III VXD 1:1 MACRO for SONY E-MOUNT & NIKON Z MOUNT (Model F072)
TAMRON’s Legendary 90mm Macro is Reborn for Mirrorless

TAMRON’s new 90mm F2.8 MACRO for full-frame mirrorless offers unparalleled sharpness from center to edge and a velvety bokeh effect. TAMRON introduces its first 12-blade circular aperture, ensuring perfectly circular bokeh and minimal vignetting especially in the macro range. The 12-blade design creates 12 rays for stunning starburst effects when stopped down, making it ideal for dramatic images with point light sources. This compact mid-telephoto macro is just 126.5mm (5″) long and weighs 630g (22.2oz.), has a maximum diameter of 079.2mm. It fits comfortably in the palm making it easy to hold for long periods of time. The 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. The rotational torque of the focus ring has been carefully calibrated to assist with precise Manual Focus operation. SonyAlphaRumors
This moderate torque makes fine-tuning the focus more exact and ensures that the results are accurate. The new hood design with a sliding window for easy filter use lets photographers rotate filters without removing the hood. The 90mm F2.8 MACRO is compatible with the dedicated TAMRON Lens Utility software. It lets users change lens settings, assign camera functions and update firmware when necessary. In addition, the mobile version is especially useful for macro photography where a tripod is often used. Users may customize functions for various still photography and videography shooting styles. This lens excels in macro, landscape, and portrait photography, offering unique photographic expressions across genres.
