Summary: First off, this is a great product for the price. Obviously it's not as good as real fisheye lenses, but for 40 bucks it does a good job. Other reviewers have complained of serious aberration/vignetting around the edges, but I found only minimal (as indicated by the price) distortion.
Summary: Delivery was fast but the packaging was very sloppy. Lens box was loose and open, all items in the lens box were in small unsealed plastic bags made you feel as if they were not brand new. The item was made in China and the workmanship is not impressive.
Summary: I read other reviews that gave a lower score, but on YouTube I found test videos and they looked great! When I received the package it came with 4 days, the fisheye works great and fits perfect with my Sony hx300!
Summary: This is just an add-on fisheye lens to an existing camera lens therefore it cannot compete with a pure, high-end, CAMERA-COMPATIBLE fisheye lens. Both lens material and lens coatings are below satisfactory quality with very poor low-light performance.
Summary: If you zoom you'll lose the fish eye effect. But this is merely an attachment to your already existing lens.. Does what it's supposed to and in comparison to the price of an actual fish eye lens it is worth it. Just be aware again that if you zoom in you'll lose the effect.
Summary: I ordered my stuff on the 6th and got a day early. REALLY like the product first 5 mins of using it and I fell in love with it. And what also made me love it even more is that my camera ( Nikon D3200 ) doesn't even need the adapter rings the fish eye just attaches right on.
