Quality and Effect

Turnikit adds a great effect to your photos and videos. Making your content more distinct by narrowing your depth of field. 

- Adding a complex lens onto your iPhone does require more light to compose a properly exposed shot.

- Some degree of vignetting may be noticeable depending on the quality of lens and amount of available light. To take full advantage of turnikit's potential, you'll want to use it in situations with lots of available light. 

- Pincushion distortion may happen with certain lenses (usually telephoto)

Just a heads up for video users. Because your lens will be attached to your phone you'll be able to hear the motion of your focus ring. External recording mics fix this issue nicely.


Cleaning and Care

The Focus screen inside turnikit can easily get dust on it, which in turn translates onto your images . Make sure not to touch it with your fingers since the oil from your fingers will damage the focus screen. You will most likely need to get a camera air blower to blow it off. If your focus screen is to far gone, a replacement will be available for purchase in the store.
