That´s great Kristian!
That restored my faith in the BMCC!

I will keep my EF order, even if I get the "old" type tomorrow and have to send it in.

My biggest fear with this camera was not that it will have problems and glitches, but that BMD will just ignore it as other companys do. That´s certainly not the case here! :)

Thank you Kristian and Blackmagic for working this out.

It is a shame that the lens companies like Canon and Tokina will not cooperate when they themselves stand to profit by selling lenses to be used on this camera. Tokina 11-16mm/2.8 was once a touted wide lens for this very camera and it helped increased Tokina sales. But they don't have the common courtesy to respond to legitimate inquiries from BM engineers working to resolve an issue involving their lenses? And what is the point of Canon withholding mechanical specifications from camera makers designed to use their EF lenses. Does Canon think that will help them sell more Canon cameras instead of Canon lenses?

Thanks for digging into this Kristian. I can only hope that the word now goes out about the fix as quickly as it did concerning the problem. These types of responses give Blackmagic tremendous credibility.

For everyone requesting an RMA here are all the Blackmagic support locations and contacts
http://www.blackmagicdesign.com/company/

I myself am a little angry that I had to pay $63 for shipping and insurance VIA UPS,
This is not a financial burden I should have to absorb.

Blackmagic Design Inc needs to somehow reimburse it's customers for this expense
as this falls squarely on there shoulders.

Darryl, you are an early adopter dude. There are always going to be some unforeseen issues or compatibility problems with brand new products. This is BM's first camera and, like RED, they are finding out all the little issues that can become big issues.

There is going to be growing pains, no matter what. That should be expected really. You're getting a fix for free, but yeah...you have to ship the camera. I don't think that's unreasonable at all.

I'd 2nd that. Just my opinion though. Everyone feels differently.
But I'm generally ecstatic about the camera's output overall.
Since this is entirely fixable, I consider it just a bump in the overall 'great ride' I'd elected to go on with BM.
As long as they continue to provide fixes where possible, I'll be happy.

Sean, It's not about the money, and to some extent I agree with you, I suppose I'm really angry over the fact this is just now being addressed, I mean what the heck why didn't they catch this problem months ago?
And now I just hope I get my camera back quickly so I can go shoot, I was sick with the flu and haven't had any play time with the camera yet.

UPDATE: How about we all get a Blackmagic Design Cinema Camera T-Shirt or Baseball Cap
For our troubles? Whataya say BlackMagic Design Inc?

I hear you!

It definitely tempers the excitment of finally getting your camera, only to find this issue, that issue, etc.

Unfortunately, now that it's in the hands of the people, the issues are presenting themselves. SSD compatibles...flange problems, etc.

It's going to be a rough 6 months I think :?

Hope this question has not been addressed elsewhere on the forum:
Will the BMCC MFT cameras have any adjustment made to the flange distance prior to shipment or will BMD stick with following the accurate specifications for the MFT mount? I am hoping there is no change from their MFT specifications and the flange distance change only applies to the EF mount.

So is this a problem on all cameras? I have mine but I haven't tried it out on too many lenses. The ones I have work but it hasn't been on the ones people have been reporting. Should I go ahead and send mine in? Or if I find out later, can I just send it in then?

BMD should really provide 2 years warranty in the EU, not just 1 year. EU law states a minimum of 2 years, so what's up with that, BMD?

I don't believe BMD is under any EU Warranty law, I think the EU Distributor/seller is, that's whats up!

Is it possible to make a statement from which Serial number the camera's are calibrated the right way from the factory? This could be a mayor help for people that may buying a BMCC that is shipped before re-calb. procedures.

Rick, as far as I know MFT is like an "opensource" mount. Canon EF is not and the flange distance problems are based in the lack of info from Canon.

Jason,

Not everyone will encounter this issue. Also, if the lenses you use are fine, then there's really no need to do anything.

It will also be counter productive to try and send the camera back to be adjusted if out of say 5 lenses, one is slightly soft as it may be an issue with the lens itself.

That's good news. Thank you Kristian. I'm love the image I'm getting from the camera and just wanted to check and get it fixed asap if needed. The lenses I use are fine but I rent alot, so I just wanted to check. Thanks for getting back to me.

No additional delays at all. Cameras are still shipping out as I type this. Maybe those that received it are not on the forums.

I'm still waiting for my camera to be returned, but I will post how long they took to fix it,
That's a given since I got no real answer when I called and asked...

What Months? Weeks? 2-3 weeks? no answer, But If I don't get my camera back soon...
They may have just purchased it as I will refuse a return if it takes longer than 3 weeks.

10 business days from when they receive the cam is the time frame BM estimated. Mine has been in Fremont, CA for 5 days.

Very happy that they came up with the source of the problem and are taking care of it so quickly. I think it shows BM is a standup company.

I think you'll find any cameras shipped after Kris made the announcement would have the new extra FFD tolerance built in...

As if the entire global bmcc buying community reads this forum, and then happens upon this thread..
Cmon jb.
Seriously, it would be nice to know if the bmcc i just unboxed had been adjusted at the factory before it left for America. Eh, i wasnt busy tomorrow anyway, why not spend some time checking!!

You have a go at people for complaining about not getting their cameras on one thread, and on another complain and ask for financial compensation on another?

Just be glad you even got a camera yet, even if you had to send it back.

BMCC Fremont, CA rec'ed ours on 3/5/13.
So technically they have had it for 9-10 business days as of the end of today.
Rec'ed an email advising that it should ship back by the end of this week.

So they are pretty close to what they estimated for time.

It is more important to me that it is fixed and calibrated perfectly.

I think BM is doing a good job with this issue.

Re: Flange distance issue

I received my BMC about 9th March I wonder if it has the flange issue fixed?

I've only ever owned Canon Lenses, after ordering the BMC I figured I'd need a lower light capable lens (it seems everyone touts the tokina 11-16mm as there's not much else around) I sold my Canon 10-22mm (beautiful lens btw) and picked up the tok what a disappointment.

You wouldn't believe the difference compared to a Canon 17-55mm and my 10-22? at times even smoked that! Now I feel like an idiot for off loading it.

I won't bother about the flange issue just to remedy the Tok at 2.8 I do know some people like the TOK but not me.

Re: Fixes etc;

It would be helpful if a manufacturing date was included in the package and an announcement of which manufacturing date onwards the flange has been corrected. Anyway, its just another example of the quirky and annoying bits of info hard to find out, such as, what firmware version is installed on the camera? Be handy to have that in the menu, on screen, in the box, on a QC note signed, ...somewhere. :?

As Kristian Lam mentioned earlier in this thread, not all cameras were experiencing this issue. Even if you got your camera before the "fix," your camera is probably fine. If you discover the issue, consider sending it in, but I wouldn't just assume your camera has a problem if you received it before a certain date.

I just don't understand that. If BMD makes the BMC with a specified flange distance to exacting tolerances, wouldn't all BMCs possess pretty much exactly the same flange distance? If one BMC requires adjustment to correct a flange distance error, then why wouldn't all BMCs require the adjustment? And if all current BMCs being shipped have had the flange distance "fix", then why wouldn't an earlier built BMC need the fix?

No i haven't sent it in, i only have canon L glass at the moment and i guess the tolerances on those lenses are tighter as i haven't noticed a problem (i haven't gone looking for it either but i did do some shots in my testing that i think would have showed infinity focusing issues on my lenses if there were some).

That's the other thing, if the flange distance gets adjusted to allow for 'sloppy' lenses, does it mean that lenses that are more exact or working fine get affected (negatively)? I'm sure i asked earlier about what would happen to 'cine' glass getting the flange distance adjusted (reluctant to say 'fixed' since it seems lenses have the slop) since the tolerance on those is generally tighter. I think i read somewhere it would negatively affect them. :(

I just don't understand that. If BMD makes the BMC with a specified flange distance to exacting tolerances, wouldn't all BMCs possess pretty much exactly the same flange distance? If one BMC requires adjustment to correct a flange distance error, then why wouldn't all BMCs require the adjustment? And if all current BMCs being shipped have had the flange distance "fix", then why wouldn't an earlier built BMC need the fix?


The "fix" is a deliberates shortening of the actual spec FFD.

This FIX also breaks some lenses because it means those that have accurate witness mark, and hard stops at infinity will no longer be accurate once the BMCC is "fixed". A lot of lenses that haven't worked ALSO have versions that do...

And this is something that BMD is doing to every single EF BMC that they ship going forward, right?

Has anyone gotten their cam back from flange adjustment? They have had mine for ten days, and no word of when I will be getting it back.

In what way would shortening the flange distance affect these accurate lenses? Wouldn't it just make them go past infinity?
