Century 16:9 1,33x on a Sigma 24-35m art lens.

[TheYuri]

So I was looking to get the Sigma 24-35mm f2 art to use as a taking lens for a century optics 1.33x adapter.

The adapters rear thread size is 52mm and the Sigma's front thread size is a huge 82mm. if I use a 82-52mm step down ring will it viggnet heavily?

I'd welcome an opinion or two, even better I'd like to know if anyone tested out something like that.

Mounting a small adapter on a big lens that is.

Thanks.
