I just got a couple of Kodak wide adapters and I thought I’d try it out on my way to and from work. They both have 37mm threads so I’ve paired them with the Olympus M.Zuiko 17mm f/2.8 pancake lens which has a 37mm filter thread. The 0.6x and 0.5x give a field of view of 10.2mm and 8.5mm respectively. Image quality is horrible but it can produce some funky looking pictures from time to time.
First four pics below were taken with the 0.6x and the other four were taken using the 0.5x.
