Q: Does the Super-Secret Spy Lens work with Prime Lenses?
A: It sure does! And your photos will look sharp and beautiful, just like normal. We recommend using focal lengths of 50mm or greater to reduce vignetting.
Q: How do I figure out what size adapter to get with my Spy Lens?
A: You'll need to know the filter size or thread size for your lens. You can usually find this marked on any filters you may have attached to your lens, or on the lens itself. Just look for a number like 37, 49, 52, 55, 58, 62, 67, 72, or 77.
If all else fails, you can also Google your lens and find the thread size online.
Will the Spy Lens work with non-SLR cameras?
It may! If you can use standard SLR-style filters on your lens, it should work. Some cameras have adapters that let them use standard SLR-mount filters. For example, this adapter for the Canon G9 allows you to use the Spy Lens!
