What We Like About the Tamron 16-50mm F2.8 (B091R)
- Constant F2.8 from 16mm to 50mm: the aperture stays the same at every focal length, so exposure does not shift while zooming
- Internal zoom: the barrel length stays fixed, which keeps balance steady on a gimbal
- 305g weight: light enough to stay mounted all day on a compact APS-C body
- 0.15m minimum focus at 16mm: close-up shots at up to 1:4.5 magnification
- Zoom lock switch and moisture-resistant build: holds the barrel in place during transport
16-50mm Standard Zoom With Constant F2.8 Aperture
The range starts at a wide 16mm, which covers landscapes, interiors and group shots, and runs to 50mm for portraits and tighter framing. Equivalent coverage on a Canon APS-C body is about 25.6-80mm, with a diagonal angle of view from 80°24′ at the wide end to 30°16′ at the long end.
Maximum aperture is F2.8 throughout, and the minimum is F16. A 7-blade circular diaphragm stays close to round up to two stops down from wide open, according to Tamron.
Optics and Coatings
The optical design uses XGM, GM, XLD and LD special elements. Tamron applies its BBAR-G2 coating to cut flare and ghosting, an AX coating on the more strongly curved elements, and a fluorine coating on the front element to repel water and grease.
VXD Autofocus and Internal Zoom
Focusing is driven by a VXD (Voice-coil eXtreme-torque Drive) linear motor. Zooming happens inside the barrel, so the lens does not extend when moving from 16mm to 50mm, which Tamron positions for vlogging and gimbal use.
A zoom lock switch keeps the barrel fixed while the lens is carried. The Canon RF version supports firmware updates through Tamron’s Lens Utility.
Close-Up Capability
Minimum object distance is 0.15m at 16mm and 0.29m at 50mm, giving maximum magnification ratios of 1:4.5 (wide) and 1:4.8 (tele).
Build and Size
The Canon RF version measures 77.6mm from the front end to the mount face and weighs 305g. Filter size is 55mm. The construction is moisture-resistant, though Tamron notes this does not fully stop water droplets from getting in.
