Sigma 100-400mm F5-6.3 DG OS HSM, reviewed by greenjeans

After having this lens for over a year I am more than impressed with it. Works well with my 70D, 6D and 6D MKII. It is my most used lens on a day to day basis. After a firmware update, it now allows lens corrections on my 6D MKII. Update did not include 6D or 70D. Great value and would definitely buy it again.

I recently got this lens to use on a Canon 90D. I did find a tripod ring but had to order it from China through Ebay. I'll post a review when I get it.

I bought a tripod ring from China from photoloving_dot_com, I think the brand name of the tripod ring was IShoot. Fit is excellent & very satisfied with the quality.

I got this lens two days ago. It is very sharp except at the short end - 100mm. Fortunately I already owned the Sigma calibration dock and used it to adjust the focusing at 100mm,, resulting in much improvement. I took both of my sample photos at around 300mm.

Here are a few more samples taken with my Sigma 100-400. They are of smoke from a fire in the Jemez mountains near Santa Fe, taken April 24, 2022.

I took these on St. Lucia in the Caribbean during a recent cruise.

I took these at the Brimstone Fortress on St. Kitts in the Caribbean.
