I have been considering the 47 SA 5.6 but can't seem to find any other options. I have read somewhere that someone said they used the 38 SA on 4X5 without moves. But according to the specs, the image circle is not big enough. But I can't figure why someone would lie about something like that. Either it covers or it does not.There doesn't seem to be anything else in the ultrawide choices for 4X5.
