Excerpt: You have to make sure the camera is turned off or you won't be able to thread this on, then you have to set the control to the max telephoto or you'll get a black halo, but you can use that halo to center your subject and create depth and make your viewer focus their attention on the center of your photo. So it could be an advantage depending on how good you are at working with the camera and not against it.
Excerpt: Does the job - allows the internal lens to extend and you to attach filters/extra zoom lens. Gets in the way of the picture below 1/3 zoom with filters only, and below 1/2 zoom with the telephoto lens. can be difficult to thread, if camera isn't perfectly horizontal.
Excerpt: The lens on SP 560 offers more than enough zoom range. 27-486 mm is quite sufficient. The reason I bought the CLA-10 conversion adapter is to be able to use filters. With the adapter there is a very significant vignetting effect at the shorter focal length end of the zoom range. It really is quite a price to pay for the ability to use filters.
Pros: Durable, Easy To Use, Improves Product Function, Lightweight
