🍆 Canon Ef 24 70 F4L Is Usm Review

The Canon EF 70-300mm f/4.5-5.6 DO IS Lens is in an interesting position in Canon's lineup - sharing the basic optical specs of the 70-300 IS. Although it is 1.5" shorter, the DO actually weighs 5.4 oz more and costs significantly more. The DO is better built and has Ring USM, but is not impressive to me optically. 6J1d.
