lenshood showing up at wide setting on EF10-22
« on: June 04, 2012, 07:49:07 PM »
Have been taking some HDR shots at wide setting and, on processing, notice the lenshood showing up on the sides, causing the need to trim both sides of the final image.
Has anyone else come across this?
using the EW-68 (same as for 17-40/4L)
cheers

Both 10-22mm and 17-40mm use the EW-83E.

It should not vignette (mine certainly didn't), provided it's mounted correctly.
EOS 1D X, EOS M, and lots of lenses

Agree.

Used this lens on my 40D with hood, could not see it. Are you using a screw on filter as well perhaps? You may be seeing that (not the hood).

Could possibly happen even if the lens hood is correctly mounted, depending on the angle of the sun and if you're shooting into the sun. I've had my EW-83F appear in one or two pics shooting wide on my 24-70, at the top & bottom, where the lens hood is largest

Sorry, but I just don't see how that's possible.  The angle of view does not change, regardless of the position of light sources or what you're shooting. By design, the lens hood does not impinge upon the area of the image circle which is sampled by the image sensor.  Depending on lighting, you could be seeing a shadow from the hood that is cast upon the lens - that's the lens hood doing it's job.  But if you are using the correct hood, and it is properly mounted, you will never see the lens hood in the image.

This (if not the Filter)

Yeah, I figured it was a shadow. It is difficult to not correctly mount the hood as it has both a red key symbol + a red dot to show when it is locked in place properly, I did a double-take, then removed the hood and was better without
