What brand and model of camera will this lens be compatible with?
This lens will fit any 58MM lens camera, the model of your camera is not relevant as long as it has the same thread size.
How can I make sure this will fit my lens?
This lens was designed for 58MM lenses.The most important thing to do is find out the thread size of your lens, your camera's lens thread size will be marked somewhere on the lens barrel or printed underneath your lens cap. This number is always preceded by a "Ø" (diameter) symbol. For example: Ø58 = 58MM lens thread size.
What should I know before I use a Wide Angle Lens?
When choosing a wide angle lens, remember; the smaller the number, the wider the angle. For instance a 0.18x is considered a super fisheye lens (notorious bubble effect) and a 0.5x is considered just a wide angle lens. This particular lens 0.43x has the best of both lenses and is considered a wide angle lens with a soft fisheye effect. Great for every type of photographic situation.
