• "Keep in mind, too, that a wide angle lens - and the fisheye is the epitome of a wide angle lens - normally has a really large DoF, so most of the time if you're just snapshooting at things farther than, say, 5 feet away, you don't have much to worry about."
• "(Raynox 0. 66x, or a Raynox 0. 3x fisheye) The 0. 66x gives a bit wider view then the normal lens on the camera, but the 0. 3x fisheye gives a full view of the rooms and seems more pleasing as it shows how big everything is, but then you can notice the fisheye is a bit distorted and I'm not sure if realtors would like/not like that so I'm not sure which one to get."
• "I especially liked the "fisheye" lens filter and the way the "Plastic" filter brought out orange and blue tones."
