Tamron has officially announced the 35-100mm f/2.8 Di III VXD (Model A078), a new fast-aperture portrait zoom lens designed for Sony E-mount and Nikon Z mount full-frame mirrorless cameras. It will hit the shelves on March 26, 2026.
If you’re familiar with Tamron’s popular 35-150mm f/2-2.8 Di III VXD (Model A058), think of this as its more portable sibling. The A078 trims the zoom range to focus on the sweet spot for portrait photography — 35mm to 100mm — while maintaining a constant f/2.8 aperture throughout the entire range. The result is a lens that weighs just 565g and measures only 119.2mm in length (Sony E-mount version), making it noticeably easier to carry around all day.
The optical design uses 15 elements in 13 groups, and Tamron says it delivers high resolution with rich, smooth bokeh — exactly what portrait shooters want. The VXD (Voice-coil eXtreme-torque Drive) linear motor provides fast and precise autofocus, which should help nail those fleeting natural expressions.
One nice touch: the minimum focusing distance at the wide end is just 0.22m (8.7 inches), giving you some real close-up versatility for tabletop and detail shots. The lens also features a unified 67mm filter size (consistent with many other Tamron lenses), moisture-resistant construction, and fluorine coating on the front element.
The lens is compatible with the TAMRON Lens Utility™ app, which lets you customize button functions and fine-tune AF behavior. Tamron also just released a new Tamron Link (Amazon) wireless accessory for remote lens control via Bluetooth.
This new lens is now available for pre-order at B&H/ Amazon.
