[QUOTE="Steve B, post: 248249, member: 15754"] Reducing the image circle does not change the focal length of the lens. It changes the eFOV just like a cropped sensor does. Are you referring to the adapters that will let you use lenses designed for cameras with longer lens registration distances on bodies with shorter lens registration distance. Like using an Olympus OM lens on a micro four/thirds camera? If the adapter has optics in it it will change the focal length of the setup but not the focal length of the lens. Just like a TC.
