Tamron has some excellent lenses in its lineup. Definitely read the review and/or view the standard image quality test results for the Tamron lens model you are considering to get the full story.
Standing out in the Tamron lineup is the Tamron 17-50mm f/2.8 XR Di II non-VC Lens for its great image quality at a low price. This lens has been the first-choice for many first-time DSLR camera owners – and for many not interested in investing more in their DSLR kits.
Tamron lenses are often selected by those looking to save money over a Canon or Nikon equivalent, but also standing out is the not-inexpensive 24-70mm f/2.8 Di VC USD Lens. This lens is a standout for its unique features and excellent image quality.
Tamron lenses are available in Canon, Nikon and other brand mounts with the Di II models being compatible only with APS-C/1.6x/1.5x sensor format cameras.
