Since late November, I’ve been shooting with a new Tamron 100-400mm f/4.5-6.3 Di VC USD lens. I bought this lens to replace my Canon 100-400mm f/4.5-5.6L IS USM lens (the old version with the push-pull zoom) I’ve been using for wildlife photography since 2012.
I’ve loved my Canon ever since the day I unboxed it. This lens has everything I wanted, long reach, fast autofocus, reasonably lightweight, and since I bought it after the Mark II version came out the price was much more affordable. I’ve taken thousands of images with this lens and it served me well over the years. Any images shot with this lens I wasn’t happy with certainly were not the fault of the lens. I planned to keep using this lens for as long as possible as I was completely satisfied with my investment.
