    Received my camera today from CVP in UK.

    Could not focus past ~1 meter on the Tokina EF 11-16mm, on either end of the zoom, many of my primes does not hit infinity, including the Zeiss and Nikon's with Fotodiox Pro and Leica 24mm with Leitax.

    Going straight back to BM, they supply pickup with UPS, so no costs involved and the shimming should take up to a couple of weeks, but hopefully sooner.

    This is my issue. I just received my BMCC EF from Adoram that I bought at NAB. I have yet to receive a response from Adorama if MY camera that I just got has had the issue fixed. I have emailed BM and no response as of yet there. Does anyone know of a way to check cameras via serial numbers or something to see if it has been fixed? Thanks.

    Are newer cameras less likely to have this issue?

    Yup.
    All is good... No back focus issues any longer.

    I'm in my 10th business day since the camera was shipped back to adjust the back focus issue and still no word as to when it will return to me.
    the folks at BMC are very nice and polite and ask me to allow them till this coming monday to find out what is going on with my camera...
    I will do that and keep the forum updated.

    so... I spoke to BM this morning about the fact that it is not cool that I spent the money to ship the camera to them. I was promised a phone call from a manager that will "fix" this by the end of today. phone call never came in, so I called them just now only to be put on hold for 30 minutes before hearing "sorry but we can't give you the shipping money you spent back"
    I asked "can you at least expedite this so I can get my camera faster since you made me spend $85 on shipping and the response was "huh... NO"
    BM really starting to piss me off.

    Yep, if you ask for it they will. I shipped mine off too early, and then got a label the next day!

    So lame Eli, I'm about to ship mine back as well. Maybe it will magically be returned as an MFT for my trouble?

    So Canon's "nominal" 44mm flange depth turns out to have some substantial "wiggle room." I.e. it's actually less, to accommodate manufacturing tolerances. So when the BMC 44mm flange depth runs up against lenses that are designed around the "real world" spec (44mm - X), they are unable to focus at infinity.

    Should BMC be liable for not knowing the secret X-factor, which apparently is common knowledge among the other, more experienced lens and camera manufacturers? Those other mass manufacturers are apparently aware enough that they know how to make their focus-shifting, non-parfocal, AF lenses, economically built to wide manufacturing tolerances, focus at infinity on the EF mount. Personally, I think the EF mount problem is part of BMD's growing pains. Whether they should pay is a matter of corporate ethics - and will be a great test of character.

    I'm just glad the MFT standards and tolerances are transparent to members of the group (or so I assume), so this should not be a problem when the MFT version is released.

    Eli, did BM pay for the shipping? I'm awaiting my RMA and I'll be pissed at the principal of paying to ship a defective camera!

    Hi Paul,

    can you post a link or a phone number so we can also contact the office and make arrangements to send off our cameras?
    thanks
