I have read that part in the review I think(at the time I was debating the 17-55 vs the 17-40), but I never made the link between the image circle of a normal lens on a crop-body.


To be honest, I never tried to see the difference in a shot with and without hood on. I always put on the hood, except with my macro lens. It blocks the flash. I assume without a lenshood you get the chance of losing contrast and color due direct light falling in, but I must say I have no idea how big the differences will be.


A nice one to check out []
