About This LensThe Tamron 11-20mm F2.8 Di III-A RXD is Tamron's first ultra-wide zoom for Canon RF-mount APS-C mirrorless cameras, delivering a constant F2.8 aperture across its entire range. Its compact design (340g, 84.2mm length) and fast RXD autofocus motor make it excellent for travel and video, while advanced optics with GM aspherical and low-dispersion elements provide sharp, well-corrected images with minimal aberrations. At $659, it commands a premium over Canon's kit offerings but delivers superior optical performance and aperture speed for dedicated APS-C shooters. | |
