Note (19/3/19): some firmware updates may affect this lens's OS performance - a couple of people have mentioned the image looks less steady now, but that Sigma tell them performance has actually improved.

Here's a famous lens from Sigma (although Tamron pipped them to the post by launching an almost identical lens just months earlier) - an extreme telephoto zoom, lens, which can be found for a very reasonable price. Here, I test it pretty extensively, on a 20mp full-frame camera, a 42mp one, and a 24mp APS-C camera - feel free to skip over any sections that don't apply for you.

All pictures taken by me on Canon 6D, EOS M3, and Sony a7R II cameras.
