For many people an introduction to photography is through a compact camera: usually, these days, one with a zoom lens covering medium-wide through to short telephoto. The next step is often an SLR and the “standard” zoom, covering the same range. The quality of this “standard” zoom can be the difference between great results and disappointment, so the choice is important. This Sigma 17-70 f2.8-70 f2.8-4 DC Macro OS HSM C Canon is both good and versatile, no disappointment here. |

New results are available on dxomark.com for the Tamron SP 17-50mm F/2.8 Di II XR VC LD Aspherical IF lens (Nikon and Canon mounts). This new review, along with our recent review of the Sigma 17-50mm, completes a set of measurements for trans-standard luminous lenses. |

Looking for a luminous lens kit? Choose Tamron or Sigma!
I agree, I have sony version o Tamron 17-55, according to my tests it`s better than Sony 28/2.8 & 24/2.8, at 50 mm Tamron have the same sharpness as my plastic fantastic Sony 50/1.8 but Tamron colurs are much better. Tamron gives the same quality pictures as new Sony 16-50/2.8, but aslo Tammy is half a price.
