Review: Sigma 17-50 F2.8 OS vs Tamron 17-50 F2.8 VC

Today I am comparing two “premium” third-party standard zoom lenses: the Tamron 17-50mm F2.8 VC ($650, B&H), and Sigma 17-50mm F2.8 OS ($680, B&H). Both offer a useful 17-50mm with fast F2.8 max aperture (at all focal lengths). Both feature optical stabilization. Both are available for multiple camera mounts (including Canon, Nikon and Sony).

Interestingly the price difference in The Netherlands (where I live) is much larger – the Tamron being sold for €374 vs the Sigma’s €565.

In addition to their similar specifications, these two have very similar size and weight, and compete in the same price range. Direct competitors, therefore. But which one is best?

The 1 Nikon system came!

The news is out! Nikon indeed came with a big announcement at midnight yesterday, and it is indeed a whole new system.

The 1-Nikon system has been announced and is initially available in two bodies – the cheaper J1 and the premium V1. Highlight features include:

  • 2.7 crop factor called “Nikon CX” (a 10mm lens is equivalent to 27mm in traditional full-frame/film)
  • Very fast shooting rates – up to 60 fps full-resolution photographs
  • Advanced video capability
  • Lots of accessories, already including 4 lenses, speedlight flash, GPS, external microphone and F-mount adapter.

To give you a sense of scale, this is the new V1 in hand:

Why we *love* Nikon

In a recent post I went on the offensive, criticizing Nikon for their overweight bodies and lenses. And yet, I own a Nikon. And I’m not ready to jump ship just yet. Why?  As Nikon is currently promoting its newest DSLR offerings, the D3100 and the D7000, I’m drooling for an upgrade to my old D80. But, realistically, why would I pay the price premium to continue investing in the Nikon system? Why not Canon, Sony or Pentax?  As we now know, it’s not for saving weight.
