About 10 years ago, Tamron released a 150-600mm f/5-6.3 lens that became wildly popular for offering photographers decent image quality paired with extreme focal lengths, a combination that used to be prohibitively expensive most of the time. Since then, we have seen an explosion of similar lenses, making genres like bird photography far more accessible than they used to be. One such lens is the Sigma 150-600mm f/5-6.3 DG DN OS, and this excellent video review takes a look at the sort of performance and image quality you can expect from it in usage.
Coming to you from Stefan Malloch, this great video review takes a look at the Sigma 150-600mm f/5-6.3 DG DN OS lens. In the sort of applications you will use this lens for, you will normally need fast shutter speeds, which might set off alarm bells when you see its maximum aperture. Yes, in lower-light environments, this might be a bit tricky, but the high-ISO capabilities of modern bodies have made this less of an issue than it used to be, and frankly, when you consider the amount of money you would have to shell out to add a stop or two of light-gathering power, the value of such a lens quickly becomes apparent. Check out the video above for Malloch's full thoughts on the lens.
