Other than that it is a great purchase and works wonderfully.

I wanted to love this lens like the other 2 (fisheye and wide angle) lenses I purchased

All in all I'm happy with the purchase given the ease of us and the top notch quality.

This was my most regretted purchase of 2017.Bottom line: It has the construction quality of a $100 product and the image quality of a $15 product.
