The Sigma 150-600mm F5-6.3 DG OS HSM | Contemporary versus the 150-600mm F5-6.3 DG OS HSM | Sports

The Sigma 150-600mm F5-6.3 DG OS HSM | Contemporary lens has a removable tripod collar. When the collar is removed, there is a rubberized ring that slides into place to cover the mounting bolts for a better hand-held experience. Sigma is rethinking lenses. From the innovative zoom lock at all marked focal distances, to lens customization for AF speed, custom focus limiter and more, the 150-600mm F5-6.3 DG OS HSM | Contemporary is a fantastic hyper-tele zoom lens designed with an eye on portability and performance.

Last year, Sigma announced a pair of zoom lenses for full-frame cameras, the 150-600mm F5-6.3 DG OS HSM | Sports and 150-600mm F5-6.3 DG OS HSM | Contemporary. With identical focal lengths and apertures, and advanced feature sets including the Sigma-exclusive lens customization, these two new champion zoom lenses share a significant amount of DNA. So, what is the difference between the Sports and Contemporary version of the Sigma 150-600mm zoom lenses?

First Impressions: Sigma 150-600mm f/5 – 6.3 DG OS HSM Contemporary

I finally got a chance to get my hands on the Sigma 150-600mm f/5 – 6.3 DG OS HSM | Contemporary while I was down in Ft. Myers for the Florida Camera Club Councils annual conference. I had a ½ day free before and after the conference and I was eager to get out and put the lens through its paces and compare its performance against the Sigma 150-600mm f/5 – 6.3 DG OS HSM | Sport version.

Are Teleconverters Still Relevant in Today’s Photography?

I had the opportunity to return to Bosque del Apache NWR a few weeks ago to lead a workshop that was sponsored by Sigma Photo, the Friends of Bosque, and Hunt’s Photo and Video. This was going to be an intensive hands-on flight photography workshop and I was bringing with me the new Sigma 150-600mm F5-6.3 DG OS HSM Sport as well as the Sigma 120-300mm F2.8 DG OS HSM Sport. Why those lenses and not my beloved Sigmonster? Don’t worry, I don’t leave home without that lens but I was especially excited about testing the two shorter telephoto lenses with the brand new Sigma 1.4 and 2x teleconverters (TC).

This morning sun rises over the San Juan Mountains
of southwest Colorado bathing the deep snow on Coal Bank Pass in low angle light. I spent two days

critical in helping us capture some amazing shots.
