If you find 140 of molded aluminum that is a little expensive, this necklace is for you! Fine finish, very reliable screws, felt very well positioned protection (do not scratch it was the objective. This collar allows you to leave the sunshade mounted upside down for storage. It is a bit heavy, but I'm not sure that the Canon version is lighter.
Recommended for those who make the macro, on my 450D, it is necessary to support the whole (more objective case) by the collar. For 30 (when will a version 12 as for type A?) It's worth the cost!
