I have just tested my 350D with following lens set at wide angle. There are dark corners in photos I take. Is that normal?

My lens
- Canon 18-55mm
- Canon 17-85mm
- Sigma 18-200mm

你可以試?用\n1) 18mm @最大光圈;
2) 20mm @最大光圈;
3) 18mm @ f/8

如果(1)有暗角, (2)同(3)可以改善暗角, 就正常

題外話:奇怪, 你會有齊呢3支鏡??

thanks for your advice =)

i bought the 18-200mm last year for travel. just bought 17-85mm for benefit of IS.

I have tried shooting indoor pictures during certain event with the an IS lens I borrowed, more sharp picutre than my 18-200mm lens coz of limited light. =)
