Canon 17-40mm f/4.0 L USM review By: Jon Tarrant, What Digital Camera (Oct 7, 2008) Overall, Canon’s EF 17-40mm f/4 L USM is designed to match the needs of demanding professionals and, as such, does so with ease.

It will also prove useful for shooting in cramped interiors. [ia]

Canon EF 17-40mm f/4L USM Lens Image Quality (the-digital-picture.com) Side note: I have found the site is a little iffy with lenses shot wide open at f/8 though it seems pretty representative of reality. The above link is shown on the 5Dsr which is 50mp. Looks pretty good.
Used to own this lens many years ago, only used on Canon 5D series cameras. As other said it's soft at edges at 17mm/F4, much better at 40mm side. The new EF 16-35L/4.0 IS is much better. I sold FE 16-35 ZA, bought EF 16-35L/4.0 IS in Canon refurbished with additional 15% off deal together with EF 100-400L IS II as then thought own two systems.
