Standard or Wide Angle Ring?

I want to purchase an adapter ring for my Lee Filter system which would fit my EF-S 10-22mm and EF-S 17-55mm. Both are 77mm. Do I need the wide angle adapter ring or would the standard ring work without causing vignetting?

Given that the 10-22mm is an ultra wide angle for the format I would be going with the wide angle version, you will probably need it. If the difference in cost was not significant I would always pick the wide angle version where I could.

Thanks. It looks like the wide angle ring is twice the cost of the standard.

Just had a look and it seems that you will need the wide version for both your lenses. The wide version is recommended for lenses wider than 35mm (I guess on FF) so your 17 with an FF eqv field of view of 28mm is well within the recommendation for the wide version. At least both lenses have the same size filter thread, so you only need the one ring.

Definitely get the wide angle one. I bought the foundation kit and the standard ring from someone. Using it on my 17-40, you could easily see it in the frame on the wide end. the wide angle one works perfectly.
