Title: Terrible for an L series
Review: I purchased the 24-70mm f/2.8L in early December 2011. I wanted to buy the perfect portraiture and fashion lens for a 24 to 35 focal length to suit my home studio. Though I am relatively new with photography, I have owned 3 L series lenses. The standard I use to judge all lenses is Canon's EF 100mm f/2.8 macro. Tack sharp. I bought the ultra wide 17-40mm L and it was blurry. I returned it. I bought the 24-70mm f/2.8 L and it too was blurry (and not the good bokeh blurry). I am returning it today. At all times I used a tripod and a remote shutter release. The 18-55mm kit lens with IS turned off was WAY sharper in my test with the same lighting conditions. All variables were the same except the lens. I used a Canon 60D. I have sent Canon an inquiry today but I cannot imagine an explanation that would resolve the issue of how a $1400 lens is outperformed by a $150 kit lens.
Is the review positive or negative?
