Ultra-wide Tamron SP zoom for Sony A-mount APS-C with LD glass and aspherical elements.
The Tamron SP 10-24mm f/3.5-4.5 Di II is an ultra-wide-angle zoom for Sony A-mount APS-C cameras, covering a 15-36mm equivalent range. The SP (Super Performance) designation indicates Tamron's premium build tier, while the LD glass and aspherical elements work to control the aberrations inherent in ultra-wide zoom designs.
Optical quality is good with the aspherical element and LD glass providing well-controlled distortion and chromatic aberration. The lens delivers sharp results at moderate apertures across the zoom range, with performance peaking around f/8. The ultra-wide 10mm end provides dramatic perspective for landscape and architectural photography.
Build quality follows Tamron's SP standard with solid construction and an internal focusing design that maintains constant physical length. The lens is compact and lightweight for an ultra-wide zoom, balancing well on Sony A-mount bodies. The focus ring and zoom ring operate smoothly with adequate damping.
On the used market, the Tamron SP 10-24mm offers ultra-wide zoom capability for Sony A-mount at very accessible prices. While the A-mount system is discontinued, this lens can be adapted to Sony E-mount via the LA-EA adapters, giving it continued relevance for Sony mirrorless users wanting affordable ultra-wide coverage.
