1-Inch Lens List

Coverage legend: Covers Likely covers Partial Likely partial Vignettes No coverage Needs test Unknown

Key Points: “Covers” should mean there is a forum thread with evidence; “likely covers” is used when there are only textual statements found stating that the lens covers; “partial” is to be used when the lens would work if a slight crop is applied, but these are always a compromise; "likely partial" is when there is textual evidence that the lens almost covers the 1-inch format; “vignettes” is to be used not when there is a light or acceptable vignette, but when the vignette is so strong it would deter one from using the lens; "No coverage" means the lens is not big enough for the 1-inch format and should not be used; “needs test” means that we're hopeful it will cover but only a test can confirm that; or lastly “unknown” is to be used when a lens is put on the list that we know nothing about but may end up being useful for the 1-inch format.

Focal reducer legend: Compatible Incompatible Unknown

Key Points: “Compatible” means the lens mount and image circle are generally suitable for focal-reducer / Speed Booster use on a smaller-format camera, assuming the correct adapter exists. “Incompatible” usually means the lens is already a native Micro Four Thirds lens or otherwise cannot accept a reducer between lens and camera. “Unknown” means compatibility should be verified before relying on it.
