As this image quality comparison shows, the 70-200 OS's predecessor, the Sigma 70-200mm f/2.8 EX DG HSM II Macro Lens, performs better at f/2.8 and f/4 except at 200mm where the OS version holds a slight advantage. Expect a modest amount of CA (Chromatic Aberration) in full frame corners at 70mm f/2.8. Sigma’s current 70-200mm f/2.8 has been on the market since 2010, and with Nikon (2016), Canon (2018), and Tamron (2017) having recently released updated versions of their lenses, Sigma’s The Sigma 70-200mm f/2.8 DG OS HSM Sport ($1457 / £1179) is a premium constant aperture telephoto zoom designed to match own-brand lenses from Canon and Nikon but at a fraction of the price. It’s one of five lens launches that marked a busy time for Sigma at the end of 2018. These include the beast of a telephoto zoom that is the 60-600mm f Because of the f/2.8 maximum aperture, the Nikon Z 70-180mm f/2.8 focuses in dark conditions without any issue. Compared to an f/4 lens, it captures twice as much light. It also allows for the use of Nikon’s 1.4x and 2.0x teleconverters, giving you a 100-250mm f/4 and a 140-360mm f/5.6 respectively. Focus speed is worse with the The Lumix S Pro 70-200mm f/2.8 is a hefty lens, coming in at 3.46lbs. This is in part due to its 22 total elements (in 17 groups – including 1 aspherical, 3 extra-low dispersion, and 2 ultra However, the new Nikon 70-200 2.8 VRII does have an edge in almost every respect. (Except looks; the original 70-200 2.8 is much more sexy looking!) It is noticeably sharper, so if you shoot high-end portraits and you need to make huge prints from a 36 megapixel D800, while shooting at f/2.8 all day long, then the mk2 is well worth it. The SP 70-200mm f/2.8 Di VC USD G2 completes Tamron's own Holy Trinity, after the Tamron SP 15-30mm f/2.8 Di VC USD G2 and Tamron SP 24-70mm f/2.8 Di VC USD G2. Both of these lenses have developed a good reputation, so the 70-200mm sibling needs to keep up the momentum. Tamron SP 70-200mm f/2.8 Di VC USD G2 for Nikon (Black) at Amazon for $1,104.95 I currently have the Nikon 70-300mm f/4.5-5.6G AF-S VR which is a great lens but I have had a windfall so am looking at getting the Nikon AF-S NIKKOR 70-200mm f/2.8G ED VR II as well as a WLxMDNk.
