Canon mode dial locking update for Canon EOS 5D Mark II and Canon EOS 7D

Effective December 6, 2010, Canon will start to provide as a chargeable service, a locking mode dial modification for the “EOS 5D MarkII” and “EOS 7D” digital single-lens reflex cameras.

This modification is available, for a fee, to owners of these cameras who would prefer a Mode Dial which locks in place and can’t be accidentally moved during normal camera operation.

For USA residents, the pricing of the locking mode dial modification service for EOS 5D Mark II and 7D cameras has been set at $100 per camera as of December, 2010. (Pricing and availability subject to change without notice.) For further details, see contact information for inquiries below.

Once modified, users must first press and hold down the central lock-release button in order to turn the Mode Dial. The modification is intended to prevent the Mode Dial from accidentally moving, once set to a particular exposure mode by the user.

That's a pretty cool update for those of you (like me) who have had the mode dial bumped without your knowledge and shoot for a while with messed up settings!

  1. First I was all like 😀 😀 😀 Hell YEAH!!!!

    Then I saw the price for this service and I was all like 🙁 🙁 🙁

    I’d rather put that $100 in the 5D Mark III fund.

  3. I don’t really understand why people would need that?

    Anyone here who “accidentally moved” the Mode Dial on the camera?
    I’ve been using those cameras for almost a decade and never ever moved that Dial accidentally. Why would I do that? It’s not in a position where it could bother me in any way.

    There are a lot of other things to improve on these cameras.

      While it doesn’t happen often, I have indeed had the mode dial move on me – and it has happened to my wife while using my 5D2 as well. Would love to have the locking mechanism. Tho I’ll probably wait for the 5D3

      I’ve also had reports of it happening to other people… just a random bump during a wedding etc.

    2. has happened to me many many times when shooting a wedding in manual and then all of a sudden, the shutter will just stay open because its in B mode! lol

      just because it doesnt happen to you, doesnt mean it doesnt happen to anyone at all.

      what i dont understand is that the mechanism is available for free, but then the next paragraph it says its $100. is that to install it? please be more clear and try to avoid directly contradictory statements back to back.

      1. Oops, my bad. thought it said “free” when it said “fee.” i take back my snarkiness. =/

  4. I’m an amateur sports photographer and it happens to me about once or twice a day when ‘m on the field.
    It’s the way I hang my camera on my shoulder. Lens (70-200 2.8 + 1.4 TC) towards my body on my right shoulder. This way I can have it hanging and still grab my camera really quickly with only one hand.
    Downside is that the mode dail might rub against my sides and change.

    Never had this problem with my old D70 cause I never hung it that way. Now I run around with my 7D and a wide angle on my D70.

  5. Dial does rotate on occasion… at times just pulling the camera out of the camera bag will change the dial. This is a good feature and should have been standard long ago.

  9. Happened to me yesterday. I am a professional photographer and I was doing a shoot for Aurthur’s day in Dublin. We had a group shot of 70 people and all of them had to have a pint of Guinness in their hand. It costs €4.50 for a pint which in total is €315 plus fees for a model dressed as Aurthur. While moving a table the mode dial got changed from Av to M and the pic was over exposed. Luckily, I shot RAW and could salvage the pic somewhat.
