Dark corners, Da 18-135 ED DC

normhead · 01-31-2011, 05:16 PM

Anyone else experience this? it's happening on quite a few shots, I think probably when the lens is set to 18mm Visible in the upper right and lower right corners. This shot taken without the lens hood.

its called vignetting and can be either the lens itself or a stack up of filters or improperlly installed lens hood.

try without the hood to see if that is it, and also without filters. You may need a low profile filter

Damn, it doesn't happen with the fairly thick polarizing filter off. Now I have to choose, the filter makes a huge difference, maybe I just have to plan on cropping that side of the frame. You can probably guess what these snow shots would look like without it, Thanks.

Little vignetting, oh well. Look at the craftsman-ship of that building.

Ya, there's a few things that are still done right.

You could try the thin filter thing, or go with a step up ring and a bigger diameter filter. I only own 77mm filters, I use step up rings to use them on smaller lenses. You can even use a rubber collapsing lens hood on the filter if you like.

Note it is on all 4 corners. Not a big issue just need a slim filter
