Excerpt: I purchased this for my 4K camcorder, Sony FDR-AX33. I was looking for a wide angle lens, not a fish eye. No black corners with the lens when the camera is in a steady, lock down shot - great!
Excerpt: I didn't expect it to work great but thought it might be acceptable when stopped down. I screwed it on the front of my 24mm Canon pancake lens which is about 38mm equivalent. I hoped the combination would give me a wider angle of about 25mm for occasional use.
Summary: The lens does appear to be well made. However, on my x920 video camera, there is obvious edge distortion and blurring. I don't think it's because the lens is bad, but rather because it is a one-size-fits-all lens. That means that with some cameras it is good, and with others, not so good.
Summary: This is my first review, but I was so let down by this product I was inspired to write. I wish I could post pictures, to show you the examples. The very center of the image is fine, but everything on the edge is blurred.
Didn't keep it...soft and distorted on Sony RX100-2

Summary: Returned it after trying it on my Sony RX100-2. Optics on wide angle lens not nearly as good as on Sony. I may have been asking too much of it...not crisp, distorted around the edges. Was hoping to add the wider angle capability and this is one of the few add-on lenses with the 49MM threads.
