    Question about 90 degree prism for Hy6/Afi

    This might seem like a dumb question but I just receive my 90 degree finder from DHW and it seems to be pretty off. When it is set to "0", the image through the finder is very off focus. I have to turn it to about -3.6 to get the image in focus. This doesn't seem correct to me. Any feedback would be appreciated since I hate having to send it all the way back to DHW and have to wait another two weeks before receiving another one.

    Thanks,

    Loc

    Once you have it set to -3.6, it works fine?

    When it is set to -3.6 it seems to work fine. My concern is that since I paid for what is a not-cheap finder, I want to make sure that I'm getting one in proper working order. Especially in the case that I ever want to sell it, I won't be able to because it's somewhat defective of if someone actually need it adjusted -2 or -3 but can't because it's already dialed near the max just to get to what I would think to be zero.

    Yes, understood. If you're sure that you don't need anything like a 3.6 diopter then I would definitely contact DHW and see what they say. Perhaps something is out of alignment.

    Sorry, I only have the 45 finder which doesn't have an adjustable diopter so I can't be of much help.
