I have recently purchased a Canon 70D, upgrading from a 40D that had some issues after years of intensive use. I still have my Canon 17-85 EF-S IS lens however I feel that the lens is too soft and is not as sharp as I would like. I was wondering if upgrading to a 24-70 F/4L IS USM is wise choice? I found it on Amazon for roughly $1,000.

The other lenses I use most frequently are Canon EF 70-200mm f/4L USM Telephoto Zoom Lens for Canon SLR Cameras and Canon EF 85mm f/1.8 USM Medium Telephoto Lens for Canon SLR Cameras. This lens is very sharp, and captures excellent colors, which I have come to expect from L-series lenses. yGtY87N.
