Standard 35mm diagonal measurement is 43.3mm & D70/100 CCD is 28.1mm : [43.3/28.1] Multiplier factor 1.5409 x 18mm film = 27.74mm digital equivalent See this URL = Duckware.com What is the effective lens factor that I use for Photo Vista Lens File? The Nikon 990 lens says 8mm - 24mm or 35mm Equivalent is 38-115mm. Fisheye FC-E8 lens adapter* that states it is an x0.21 Magnification. 38mm x .21 would = 7.98mm or 8mm 115mm x .21 = 24.15mm or 24mm. Then look for 8mm or 24mm Photo Vista lens file to stitch your images. The above tip provided by Rodrigo in the UK The wider the lens [smaller the lens focal length (fl) value] means that you are able to capture more view. Fisheye 1 is 8mm fl full 180° circular view.. so you would capture ALL from the tripod center point. Fisheye 2 is equal to about 16mm fl so the view is truncated so the NON view area is up to 3 feet in front of the tripod. Using a 24mm lens fl you won't capture anything between the tripod and 7' in front of the camera. The interesting point of all this is if you are taking a panorama in a restaurant, many of the near by tables will be missing from your images.... So be sure to consider this visual void when selecting lenses for your camera.
