Lens Review

Another intriguing offering in our database is the Canon EF70-300mm f/4.5-5.6 DO IS USM. It’s pricey at $1,270 but appealing as an ultra compact (if still relatively heavy at 720g) model, thanks to the adoption of the firm’s innovative Diffractive Optics (DO) technology. Although only introduced in 2004, the resolution at maximum focal length is poor accounting for the low DxOMark score of 12.6 when mounted on a Canon EOS 5D Mk II and it’s correspondingly lower still on an EOS 7D (at 10 points).
