Canon 5D and 17-40mm 1:4l lense shows corners at 17mm

Does somebody have a solution for this problem?

1 ACCEPTED SOLUTION

Yes, stacked filters will show on most wide angle lenses.  Even at more standard focal lengths on some lenses.

 

Might I ask, what is the glass filter?  If it's just a UV filter, take it off when using a polarizer or ND.

SHow corners?  Perhaps the corners of the lens hood?  If that's the case you probably don't have it set properly; make sure it's firmly seated and locked in.  Or, perhaps you're using a 3rd party hood?

 

There's some amount of vignetting (easily auto-corrected in most processing programs) when on the wide side of the 17-40, but you still get full use of the sensor.

I found it. It is the polarizing filter. It seems that this lense doesn't accept two filters. A glass filter  and the polarizing. Thanks for your feedback it halped me looking at this.

And you are probably not using low profile filter. I can stack 2 low profiles filter on 16mm just fine.

If it's the Canon 16-35/2.8L II you're referring to, that uses 82mm filters. The 17-40 uses 77mm.  

 

"Slim" filters tend to be more expensive. And some of them don't have threads on the front, so need a special lens cap.

 

B+W's "standard" mount filters are pretty slim to begin with (tho they to offer slim, as well)... I've never had any vignetting problems with them on even the widest lenses. But I also would never stack a polarizer on top of a clear "protection" filter. Previous response to remove the clear filter first, before installing the CPL, is correct.

🙂 ... I often stack ND with CPL to prolong shutter speed because my 3stop ND sometimes is not enough. I may get around to get the 6 stop or 10 stop soon.

Yup, I've done this on my 17-40 and didn't have issue, but I have the B+W XS-Pro CPL, which is super slim.
