Comments on: Free Wallpaper & Canon Lens Review: Flying High http://www.dphotojournal.com/free-wallpaper-flying-high/ Tue, 07 Oct 2008 15:13:54 +0000 http://wordpress.org/?v=2.3.3 By: Justin http://www.dphotojournal.com/free-wallpaper-flying-high/#comment-119679 Justin Thu, 07 Aug 2008 12:57:24 +0000 http://www.dphotojournal.com/free-wallpaper-flying-high/#comment-119679 Been using the Canon EF 17-40mm as well and find it to be a fairly competent lens with no major drawbacks. Utilizing Ring USM, the Canon EF 17-40mm f/4.0 L USM Lens focuses very fast, quietly and accurately. Wide open center of the frame sharpness ranges from great on the wide end to good on the long end. Corner sharpness is the reverse - ranging from good at 40mm to soft in the full frame corners at 17mm. I'd suggest having a look at what B&H and some of the other major online shopping sites can assist with. I ended up buying mine in South Africa from the guys at wantitall. Decent price. http://www.wantitall.co.za/Canon_cc493720 Been using the Canon EF 17-40mm as well and find it to be a fairly competent lens with no major drawbacks.
