Ultra-wide zoom for APS-C E-mount

The Tamron 11-20mm f/2.8 Di III-A RXD is built for Sony E-mount APS-C mirrorless cameras. It covers a 11-20mm focal range with a constant f/2.8 aperture, letting photographers work in tight interiors or expansive landscapes without swapping lenses. The bundle adds a ProOptic 67mm filter kit, an Ulanzi MT-11 octopus tripod, a sling strap, cleaning tools and a pouch. It suits creators who need a single fast wide-angle for everyday carry.

Consistent brightness under sustained use

The constant f/2.8 aperture holds exposure steady across the zoom range, so video shooters and burst photographers avoid the brightness drop common with variable-aperture designs. Close focus reaches 0.15 m at 11mm and 0.24 m at 20mm, allowing detailed near-subject work during extended sessions. The RXD stepping motor drives autofocus quickly and quietly, reducing hunting when the lens is used continuously for vlogging or event coverage.

E-mount APS-C image circle defines the limit

The lens projects an image circle sized for APS-C sensors, so it cannot cover full-frame Sony E bodies without vignetting or crop mode. The 67mm filter thread accepts standard circular filters, but larger diameters require step-up rings not included. Buyers needing full-frame coverage or a wider maximum aperture must look elsewhere, as this design is optimised specifically for the smaller format.

Questions about this item

How quiet and cool does the Tamron 11-20mm f/2.8 Di III-A RXD run during all-day shooting?

The lens has no internal motor noise or heat concerns; its RXD stepping motor operates silently and the compact barrel stays cool during extended use.

Which camera mount must I already own for this Tamron 11-20mm f/2.8 to attach and autofocus?

You need a Sony E-mount APS-C mirrorless body; the lens is designed exclusively for that mount and will not fit other systems.

Will the 67mm filter threads on this Tamron 11-20mm f/2.8 accept the circular polariser I already use on my older lenses?

Yes, the front thread is 67mm, so any 67mm filter — including your existing polariser — screws on directly without step-up rings.
