While already available for several other brands, Sony and Pentax are finally getting a crack at the Sigma APO 120-400mm F4.5-5.6 DG OS HSM optically-stabilized lens, set to become available very soon.
Sigma seems to be trying to play catch-up when it comes to lenses for Sony and Pentax mounts, as just last month the lens manufacturer announced the APO 150-500mm for full-frame DSLRs made by these two camera brands.
This particular Sigma lens is equipped with several professional-level qualities, including a coating to reduce flare and ghosting, a glass element to correct for chromatic aberration and a rear focus system minimize pixel fluctuation.
The lens also incorporates Sigma's signature optical stabilizing system, permitting shutter speeds up to four stops slower than normal.
Here's a few other basic stats on the Sigma APO 120-400mm:
- Maximum aperture: F4.5-5.6
- Minimum aperture: F22
- Minimum focusing distance: 59.1 inches
- Weight: 61.7 ounces
- Dimensions: 3.6 inches × 8 inches
Both the Pentax and Sony versions of the 120-400mm Sigma lens will be available by the end of May in the UK, with an MSRP set at £766.30 ($1,132).
