Sigma stabilizes 50-150mm F2.8 EX DC APO OS HSM

By dpreview staff on Feb 8, 2011 at 17:02 GMT

CP+ 2011: In a group of releases, Sigma has unveiled an optically stabilized version of its 50-150mm F2.8 fast telephoto zoom for APS-C DSLRS. The 50-150mm f/2.8 EX DG APO OS HSM gives a field-of-view range equivalent to around 75-225mm on a 35mm system, but in a design that is smaller and lighter than full frame 70-200mm F2.8 designs. The latest, 'OS' version is claimed to offer the ability to get stable shots at shutter speeds four stops slower than without it. It features a completely revised optical design with 21 elements in 15 groups.

Press Release:

Sigma 50-150mm f/2.8 EX DC APO OS HSM

Compact, large aperture telephoto zoom lens with Optical Stabilisation

  • Compact, lightweight, large aperture telephoto zoom lens
  • Sigma’s proprietary Optical Stabilisation system
  • Rounded 9 blade aperture
  • HSM for fast and quiet autofocus
  • Compatible with Sigma EX DG APO Tele-Converters

The Sigma Corporation is pleased to announce the new Sigma 50-150mm F2.8 EX DC APO OS HSM, designed especially for digital SLRs with an APS-C size image sensor.

Sigma’s proprietary OS (Optical Stabiliser) system enables hand held tele-photography by allowing the use of shutter speeds approximately 4 stops slower than would otherwise be possible.

Six SLD glass elements compensate for chromatic aberrations and provide high image quality throughout the zoom range. The Super Multi-Layer Coating reduces flare and ghosting and ensures sharp and high contrast images even at the maximum apertures.

The lens design adopts an inner focusing and inner zooming system to provide convenient handling and the HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus while allowing full-time manual focus override.

This lens has a minimum focusing distance of 80cm (31.5”) and a maximum magnification ratio of 1:6.3. The rounded 9 blade diaphragm creates an attractive blur to the out of focus areas of the image. The addition of Sigma’s TELE CONVERTER 1.4x EX DG APO or 2x EX DG APO produces a 70-210 F4 AF telephoto zoom lens or 100-300 F5.6 AF telephoto zoom respectively.

Can the OS work with NEX LA-EA2 adapter?

By flyryd (Jan 6, 2013)

yes, all sigma lens with OS work with la-ea2. i've got 4 OS lenses myself, and they all work. HSM also works.

Great and useful focal length for APS-C users, but little bit too big I guess.

An exciting release in my opinion. I shoot APS-C and the FF 70-200mm is too cropped. A 50-150mm will be welcomed by many.
Considering its a 70-200mm equivalent for APS-C, I feel that the price is excellent, as there is nothing in the market that comes close.

Too expensive? Who offers a stabilized f/2.8 50-150 for APS-C at under $1100? Nikon's closest offering is a $2500 70-200 f/2.8 beast. Closest Canon is the very nice f/4 70-200 is. And both are FF lenses. And the Canon is f/4. So, why would you think any of the Aftermarket manufacturers would what to offer their lenses at their cost! This is a reasonable price for an introduction. This is an initial price, so wait until it drops in price if you don't like the price. Wait for a short time and a few hardly used pieces will show up for sale and save even more.
The size is a concern of course, but it is supposedly optimized optically for APS Cameras and as such has an appeal at the short end for us who shoot the smaller sensor. In the mean time, for me, it beats anything Nikon offers spec wise in the APS world and warrants a good look given that they have the second best Stabilization system out there. As to ergonomics... I actually find that Sigma does a pretty good job.

Certainly not "smaller;" it is in fact exactly the same size as the 70-200 f 2.8 OS (3.4 x 7.8"). It has ONE less glass element, so it might be a teensy bit lighter, but not enough so that it makes any difference. This despite having LESS depth of field isolation at maximum aperture (a truly "equivalent" APS-C would have to be a stop faster, which would actually not only make it lose the supposed size and weight "advantage," it would actually make it heavier than the FF equivalent, based on this lens' specs).

Sigma needs to ditch this OS line. Their ergonomics suck, and as noted below, the prices are too high to make them attractive alternatives to Nikon/Canon glass.

You don't have to buy it.

You guys are nuts! Do you want quailty or not? You won't get quality at 10oz and $400. But then, go ahead. I don't need the competition.

50-150mm F2.8 II has enough image quality. I don’t need some extra quality for a double weight and price.
