Sigma 150-600mm f/5-6.3 DG OS HSM Sports & Contemporary mechanical comparison

Sigma 150-600mm f/5-6.3 DG OS HSM Sports & Contemporary mechanical comparison (click for larger)

DC Watch met the developers of the 150-600mm Sports and Contemporary lenses for a long interview. The awkward Google translation (the truth about Sports lenses is at the end of this post) likely made me miss a few bits of info, but here you go nonetheless.

  • Although the two lenses were unveiled at the same time, Sigma took a few extra months to refine the Contemporary version.
  • The extensive use of metal in the S plays a big role in the extra weight (2,860 g) compared to the C (1,930 g), which utilizes more plastic (TSC I guess).
  • The size of the front lens was mostly determined by the position of the diaphragm. The closer to the sensor plane, the larger the front lens has to be, for a given level of peripheral illumination. That’s why the S boasts a larger front element. It’s not a matter of corner resolution.
  • There should not be any noticeable difference in OS effectiveness between the two models. Both incorporate the latest advances in this technology, with just a few differences in how the units are integrated.
  • Following the previous point, Sigma didn’t want to cripple the 150-600mm C, even though it is supposed to be a lower-end lens. In particular, it offers the same feature-rich switch panel as found on the S version.
  • The slit at the base of the C’s lens hood helps eliminate debris and reduce motion when the wind blows, by allowing the air to flow out.

The Fun Bit

Thanks to Google Translation for revealing what Sigma’s Sports category is all about (but we already had a hint)…

For a model that has been planned as APO 150-500mm F5-6.3 DG OS HSM successor, would contradict the specification occurs when the you can put the all the elements required for the super-telephoto zoom of this class, robustness and reliability and differentiate into two products of and sex-oriented “Sports” line, of portability and mobility-oriented “Contemporary”.
