Tamron's budget ultra-wide for APS-C — generic listing of the SP 10-24mm across multiple mounts.
The Tamron SP 10-24mm f/3.5-4.5 Di II LD Aspherical IF is an affordable ultra-wide zoom for APS-C DSLRs, available in multiple mounts. This is a generic listing without specific mount identified — see ID 3484 (Sony A) and ID 3657 (Nikon F) for mount-specific descriptions. It covers a 15-36mm equivalent range at a budget price.
Optical performance is decent for the price class. Centre sharpness is good, particularly at mid-range focal lengths. Corners are softer at 10mm wide open. The SP designation ensures Tamron's premium build quality. LD and aspherical elements help control optical aberrations. Internal focusing prevents front element rotation — useful for polarising filters.
Available in Canon EF-S, Nikon F DX, Sony A, and Pentax K mounts. Filter thread is 77mm. Weight is approximately 406 grams. Build quality is solid SP tier. No image stabilisation. The IF design keeps the front element stationary during focus. The Tamron 10-24mm Di II VC HLD is the improved successor with stabilisation.
Affordable on the used market. Check zoom and AF operation. Verify which mount version this listing represents before purchase. A serviceable budget ultra-wide for APS-C DSLR shooters wanting dramatic wide-angle perspectives at a modest price. The VC HLD successor is preferred where available.
