The Tamron 17-70mm f/2.8 Di III-A VC RXD (Model B070) is an expansive, high-speed standard zoom lens engineered specifically for APS-C-format Sony E-mount mirrorless cameras (delivering a broad 25.5-105mm full-frame equivalent focal throw). Reimagining the standard kit zoom into an all-in-one professional workhorse, this optic pairs an extended 4.1x zoom ratio with a bright, constant f/2.8 maximum aperture throughout the focal range. This consistent light-gathering capability provides strong low-light performance, dependable exposure control, and shallow depth-of-field separation for event documentation, travel landscape capture, street photojournalism, and handheld video production. Integrated Vibration Compensation (VC) utilizes specialized algorithms to mitigate handheld camera shake, ensuring sharp still exposures at slower shutter speeds and smooth framing during active video capture.
The optical formula incorporates 16 elements arranged in 12 groups, integrating two glass-molded aspherical elements, one hybrid aspherical element, and two Low Dispersion (LD) glass elements. This configuration actively curbs spherical aberrations, geometric distortion, and chromatic fringing to deliver tack-sharp resolving power across the entire frame. Optical surfaces are treated with Tamron’s BBAR (Broad-Band Anti-Reflection) coating to eliminate internal ghosting and flare in harsh, direct backlighting. Autofocus is powered by a high-speed RXD (Rapid eXtra-silent stepping Drive) actuator, providing swift, accurate, and whisper-quiet focus acquisition fully compatible with Sony Fast Hybrid AF and Real-Time Eye AF. Featuring a close 7.5-inch minimum focusing distance at the wide end (1:4.8 reproduction ratio), moisture-resistant barrel sealing, a protective fluorine front coating, and a rounded 9-blade diaphragm, this versatile everyday zoom delivers reliable performance in good, field-tested condition.
CONDITION DIAGNOSTICS & PHYSICAL NOTES
Included Components: COMPLETE STANDARD ZOOM OUTFIT. Supplied with the Tamron 17-70mm f/2.8 Di III-A VC RXD lens, genuine Tamron 67mm front snap-on lens cap, genuine Tamron rear E-mount lens cap, and dedicated Tamron petal-type bayonet lens hood (HA036). (Camera bodies, 67mm filters, and carry pouches sold separately unless pictured).
Exterior & Barrel Status: GOOD CONDITION. The matte black composite polymer barrel chassis, ribbed rubber zoom ring, electronic manual focus collar, and bayonet mount show typical cosmetic signs of standard field handling, including light surface scuffs and minor finish rubbing along the outer barrel and hood rim. All printed focal length numbers, switchless barrel markings, and Tamron brand badging remain clean, sharp, and fully legible.
Optical Status: GOOD CONDITION. Both external front and rear optical glass surfaces are clean and free of deep scratches, gouges, haze, fungus, or element separation. The internal optical assembly contains scattered dust particles typical of telescoping zoom optics; extensive bench testing and sample test exposures confirm that these internal particles do not render into final captured images, nor do they degrade sharpness, contrast, or color transmission across normal working apertures. Protective fluorine front coating and BBAR internal coatings remain fully intact.
Mechanical & Electronic Status: FULLY FUNCTIONAL. The RXD stepping autofocus motor locks onto subjects swiftly, accurately, and silently; full compatibility with Sony Fast Hybrid AF, Real-Time Eye AF (human/animal), and Direct Manual Focus (DMF) operates smoothly; the zoom ring extends and retracts across the entire 17-70mm focal range with uniform, factory-correct resistance; the Vibration Compensation (VC) system engages cleanly and steadies the live view feed; the 9-blade rounded diaphragm stops down crisply without sticking or oil migration; gold-plated E-mount electronic contacts communicate Exif metadata and in-body corrections reliably with host Sony cameras with zero error codes.
KEY FEATURES & PERFORMANCE HIGHLIGHTS
Constant f/2.8 Maximum Aperture: Maintains consistent light gathering and shallow depth-of-field separation across the entire 17-70mm focal range.
Versatile 4.1x Zoom Span: Spans 25.5mm wide-angle vistas through 105mm portrait and telephoto perspectives on Sony APS-C crop-sensor bodies.
Built-In Vibration Compensation (VC): In-lens optical stabilization mitigates handheld camera shake for sharper low-light photos and steady video capture.
Advanced Optical Architecture: Combines 2 glass-molded aspherical elements, 1 hybrid aspherical element, and 2 LD elements to correct aberrations and distortion.
Broad-Band Anti-Reflection (BBAR) Coating: Suppresses internal reflections, flare, and ghosting to maintain punchy contrast and color neutrality in backlit scenes.
Quiet RXD Stepping AF Motor: Delivers high-speed, quiet, and precise autofocus tracking optimized for both fast-action stills and smooth video racking.
Close-Focusing Macro Capability: Focuses down to just 7.5 inches (0.19 m) at the 17mm wide end with a 1:4.8 maximum magnification ratio for dynamic close-ups.
Rounded 9-Blade Diaphragm: Engineered with 9 curved blades to produce smooth, natural bokeh and circular out-of-focus background highlights.
Weather-Resistant Construction: Internal rubber sealing rings and a rear mount gasket protect internal components against dust and moisture in the field.
Protective Fluorine Front Coating: Repels water, grease, and fingerprints, making the front glass easy to wipe clean on location.
Standard 67mm Filter Thread: Shares the unified 67mm thread standard of Tamron’s mirrorless lineup for effortless sharing of polarizers and ND filters.
