* For 8" HD version, add 1.0" to length; for 11" and 14" HD versions, add 0.5" to length. Camera adapter length varies depending on the HyperStar lens and camera model. Adapter length is HyperStar backfocus minus camera backfocus. (For example, on a C11 HyperStar, the backfocus is 59.7mm; using a Starlight Xpress camera with 18.3mm backfocus, the adapter length is 59.7 - 18.3 = 41.4mm, or 1.63")
