Image quality results have been added to the Sigma 150-600mm f/5-6.3 DG OS HSM Sports Lens review page.
The first copy of this lens to go through the lab showed a rather strong misalignment issue (Sigma replaced that lens for the owner – great service). As the 150-600 Sports lens model remains unavailable, we have Sigma USA to thank for the loan of this second lens. This new lens also shows some side-to-side variances, but the differences are less-significant than the first model. The left side of the lens is not as sharp as the right in the widest focal length tests and, noticeable in the results presented here, is that the right side is softer at 300mm.
Overall, this lens is a very good performer. I spent lots of time behind it this past weekend, capturing over 2,000 images at the sporting events I covered. I look forward to sharing that experience. In the meantime, here are some comparisons:
Sigma 150-600 Sports vs. Sigma 150-500 OS (be sure to compare the long focal lengths)
Sigma 150-600 Sports vs. Tamron 150-600 VC Lens
Sigma 150-600 Sports vs. Canon 100-400mm L IS II Lens
Demand is still outstripping supply of this lens right. If you want a 150-600 Sports lens in your kit, the best option is to get in line at B&H.
