    Works great with both Canon EF/EF-S lenses. Tried using with a Sigma lens and get a vignette effect. Not sure if issue is with my specific lens or not

    If you are upgrading cameras and want to use your old lens this is a must. My one complaint which is not so much with the product but the compatibility is that it did not work well with my sigma art lens. It added some dark vignetting around the edges.

  • No disappointment here

    If you already have lenses from a collection you’ve built over the years; then this is a product you need. Why buy all new lenses because you’ve purchased an upgraded unit? Get this and save money by using your current ones. You can thank me now!!
