As an avid photographer, I thought the Lightdow lens would be a great addition to my kit. However, it fell short in nearly every aspect. Although it was easy to attach to my camera, the image quality was subpar at best. Through trial and error I found that it worked best in brightly-lit environments, which defeated the purpose of an f/1 lens. Additionally, it was not compatible with all of my electronics .Overall, I would not recommend this product..See full review
