Cokin Z-Pro Filter Holder on your Ultra Wide Angle Lens
Vignetting at the widest end!
So often, when we shoot landscape photography using our UWA lenses, we found ourselves plagued by the problem of vignetting on the widest end when we have our Cokin filter holder screwed on. I have found this tip from another forum, but as it is not very appropriate to link another forum to CS, I have simply taken my own picture and share it with all us CSers here.
What is my set up?
It is a typical set up similar to many of our brothers here.
I use the Cokin Z Pro series with the 77mm and 82mm adapter rings on various lenses.
And when I shoot with my Full Frame camera with the 16-35mm lens at the widest end, the vignetting from the filter and filter holder will always force me to zoom in to around 22-24mm before the vignetting disappears.
I am sure this problem is faced by photographers of all makes and models of cameras with all the other models of Cokin Filter holders.
But do take a look at this and it might just solve your problem.
What can we do to significantly reduce vignetting?
Simple. Instead of screwing in the Adapter Ring first, followed by slotting the Filter Holder from the top, do this:
- Make sure any UV filters are removed
- Slot the Adapter Ring into the filter holder's opening, with the adpater ring's thread side facing towards the lens' front element.
- Now gently screw in the whole contraption until the Adapter Ring is snugly screwed well onto the lens' threads.
- The Filter Holder will be firm held between the Adapter Ring in front and the lens rim behind - and it will be so firm that it will not fall off at all!
- Turn to 16mm end of the lens, and on a Full Frame camera, you will see NO VIGNETTING at all!
Here is how the contraption appear.
I would urge all UWA lens users, no matter if you are using Full Frame or Cropped bodies, no matter what Filter Holder systems, to give this idea a try.
I cannot promise that it will definitely work on your system (perhaps not on Tianya system), but there is no harm trying out and you might just find yourself solving the persistent problem of vignetting.
Please try out your Filter System and share your findings with CSers.
I have no experience with other Filter systems and thus I sincerely urge all to test out this method with your own Filter system and keep us informed and updated.
Thank you all in advance.
