Canon EF 70-200mm f/4L IS USM

Canon EF 70-200mm f / 4L IS USM is a well-known zoom lens that does not require closer presentation to Canonphotographers. It’s superfast, razor sharp and has a relatively compact design and low weight. I appreciate this f4 instead of the almost double expensive f2.8 lens mainly because it’s half as heavy. 760 grams instead of 1490 grams makes a big difference after some hours of shooting.
