Field flatteners, reducers and coma correctors give their best image only at the exact lens-to-sensor distance they were designed for. This set of three thin T2 spacer rings (article 10310231) from Gerd Neumann jr. lets you fine-tune that distance in small, repeatable steps.
The set contains three rings, 2 mm, 1 mm and 0.5 mm thick. Placed over a standard T-thread, singly or combined, they lengthen the optical path in 0.5 mm steps up to 3.5 mm in total.
