Hi I just got a Canon EOS 450D Twin IS kit. I went out today to take some pics and I think i may have a problem with the 55-250 IS lens. Here are some pics to show what i mean. 1. Sides are blurry. Really weird looking. EXIF: 1/500s, f/8.0 2.Looked perfect in viewfinder. I distinctly remember so because as I looked through the viewfinder I thought "This will look good printed" EXIF: 1/400s, f/7.1 3. You can see a weird blur around the edges EXIF: f/6.3, 1/2000, ISO 400. If anyone thinks it is a lens problem please let me know as I am going to cairns in 7 days and would like to have it repaired/replaced in time. Thanks.
