Tips：

Please check the following description before order placed:

Optics is based on the original sigma art 50-100mm f1.8 lens. Our modification is change the lens into full manual, and install housing with gears onto original lens, its optics will not be improved, and still there is breathing effect. We suggest you google the original lens reviews or test it in local shop before order in our shop.

If you have original lens, you can send it to us for modification.
