Canon EF 70-300mm f/4.5-5.6 DO IS USM Lens Review

The Canon EF 70-300mm f/4.5-5.6 DO IS USM is a compact 70-300mm zoom lens feature a unique optical technology called “Diffractive Optics” (DO). This unique system allows for Canon to make the lens significantly more compact than a standard 70-300mm. The lens features Canons Image Stabilization and USM focusing systems but carries a rather hefty price premium over the standard Canon EF 70-300mm IS USM lens. I have not formally tested this lens, but have been intrigued due to it’s small size and significantly lower price when purchased used.
