Tamron's legendary APS-C constant f/2.8 — the SP 17-50mm for Canon without VC.
The Tamron SP AF 17-50mm f/2.8 XR Di II LD ASPH IF for Canon EF is the non-stabilised version of Tamron's excellent APS-C standard zoom. The constant f/2.8 across 26-75mm equivalent was revolutionary at its price point. SP build quality. XR and LD elements control aberrations. IF internal focusing. A landmark APS-C standard zoom.
Outstanding for the price — the SP 17-50mm f/2.8 consistently matched or exceeded first-party kit zooms at any aperture. Centre sharpness excellent from f/2.8. Constant aperture provides consistent exposure and bright viewfinder. The non-VC version is sharper than some VC alternatives in tests. SP build quality is solid.
Canon EF mount, APS-C. Filter thread 67mm. Weight approximately 434 grams. SP build quality. IF design. No VC stabilisation on this version — the VC version adds stabilisation. The non-VC version is sometimes preferred for marginal optical quality advantage. Screw-drive or motor AF depending on specific version.
Very affordable. The non-VC may be marginally sharper than VC version. Check AF. One of the most celebrated APS-C standard zooms ever made. The constant f/2.8 at budget pricing was revolutionary. The VC version is preferred for stabilisation convenience. Both are excellent. An outstanding value APS-C standard zoom.
