    Without having the camera in hand, it appears that it was subjected to some sort of impact that dislodged the screen. Perhaps in shipping?
    Rather than mess with it I believe you should return it to KEH & have them repair/replace the unit. That is Before you attempt to correct it.
    Heavily sedated for your protection.

    So based on everything here and a phone call with KEH, especially keeping in mine that the focusing screen is supposed to be permanent and my unusual setting for the diopter, I'll be sending it back to get it fixed or whatever they can do asap.

    Thanks!

    Yes, the ground glass is definitely out of whack. See if they will trade you a complete Pro or Pro TL for this body. Then you would gain removeable backs, removeable prism, different screens, different winders, etc. The Super would be good too, and it has a 1/60 mechanical setting in case the battery dies.

    Heck, I would even trade it for a good 1000s. You can't change the backs, but you still get two (or three) winding options, several view screen options, and several finder options. They are like a tank, I'll probably never get rid of mine.

    so what's the benefit to having different screens? Also, I'm fairly satisfied with the winder on this camera, it feels pretty comfortable and I don't really want to put money into other winders when I'm fine with what I have.

    I'm not sure about the backs and prism though. The backs might work well but I'm still not sure as to why I might want to change the prism unless it was just to take it off and maybe use something else like a loupe to check focus though it's a pretty small spot to put a loupe or something similar on. I think the 1/60 mechanical shutter w/o batter sounds good though.

    I'm hoping to send it back today to probably just get it fixed unless I see that they have something that's similar that I could trade for.

    Thanks!

    IMHO the advantages (other than cost) of the 645E are:
    1) lighter in weight;
    2) can use the thumb operated Rapid Winder; and
    3) built in diopter correction in the finder eyepiece.

    The biggest reason to want interchangeable screens is so that you can install a grid screen. The second reason - some screens are better for extreme closeup and other specialised purposes.

    Interchangeable backs speak for themselves.

    It is handy to be able to switch to a waistlevel finder if you are photographing tabletop or ground level scenes

    The build quality of a ProTl is heavier and more durable

    If it matters to you the TTL flash capability on the ProTl is good

    Just a few observations from an owner of one "Pro" body and two "Super" bodies

    Hmm, I see what you're saying but I think for now I'm going to have to stick with what I have...after looking at the prices haha. I paid about $205usd for the 645E and being a college student without a real income, yeah. I started looking at the ProTL at the beginning but I ended up getting studio lights instead. I've already gotten a fair amount of work out of them so I think it was worth it. I'll probably have to stick with what I have now but until I have a real income I'll probably just have to stick with this.

    Also, I'll search around but what does the grid screen help with? It's not just a grid is it? Is it easy to explain how some are better suited for close up? As I said (or maybe as you figured) this is basically my first medium format and before now I've just used 35mm and specifically a camera where I can't change anything else besides the normal SLR stuff.

    Thanks for all your knowledge and advice!

    The grid screens help you make sure that your image is, or at least appears to be level or vertical or square (as circumstances require).

    Some of the other screens are more usable when the circumstances or equipment make it impractical to use split image or microprism focus aids (such as stopped down photography, with shift lenses or bellows). In addition, screen patterns and focus aids are acquired tastes - some people just prefer some choices over others. Whether or not one screen type will appeal to you more than others is hard to predict - it's best, if possible, to try a few, and then decide for yourself.

    One other point, if you can change the screen, it means you can easily clean the screen. There is almost nothing more irritating than dust and dirt trapped on a fixed screen (how does it get in there anyways )

    The price you paid for the 645E is good. Have fun.

    Hi everyone.

    Have the same problem here.
    I've bought my 645e on eBay from the US seller and its viewfinder shows no infinity, although at the film plane it's OK.
    I will not ship it back because in that case I should pay for the shipping and it's expensive here in Russia where I live
    I have searched through the internet for similar problem discussions and that thread is the only one I found.

    I intend to try to fix this by myself as I have some basic experience in camera repair.
    Would the pics of disassembly process be useful here?
    Sadly, I had no success trying to find any service or repair manual or disassembly guide for the 645e so I'll be all alone.

    BTW, I found that 645e HAS INTERCHANGEABLE focusing screen!
    Remove the lens and look inside up along the lens mount plane. You'll see small metal "L"-shaped hook that locks front edge of the screen frame. Gently pull it to the left with a toothpick or something and it will release the frame with the screen giving you the ability to take the screen out for cleaning or replacement.
