The Nikon CFI Plan Achromat 10X NA 0.25 objective has proved to be an excellent lens for this purpose. It delivers its rated magnification when used with a 200 mm telephoto or “tube” lens, and it has been shown able to cover a full-frame sensor (36mm x 24mm) with high quality image when used with an appropriately wide telephoto. With an APS-sized sensor, this objective can also be pushed down to as low as 5X, by using rear lenses as short as 100 mm.
