5D Mirror Drop Out

[shojibake]

Personally i don't think machine gunning for fireworks is considered mishandling. Equipment shouldn't be treated with kid gloves. Supposedly the glue holding the mirror doesn't hold too well under humid & hot conditions.

waa like that v dangerous man. Dont know when will the mirror drop? :sweat:

he said he wanted to shoot, took out cam and was all black. he thought forgot remove lens cap then realise lens not cap. then remove lens realise mirror dropped out...cant imagine you have a L lens then mirror drop hit against the rear element and scratched it.

Actually I am puzzled too.. why this never happen for 30D or 400D?? :dunno:

they focused too much on how to fit the FF sensor?

Interesting analogy.. if compare this way.. 5D vs 1Dmk3 will be similar to 30D vs 5D :lovegrin:

no la...this is not math la... what I mean is that Canon never put effort on QA/QC on non-1 series cam...

maybe the 5D mirror is bigger

this is the worst situation...rear element is not cheap to replace...

Has been raised a lot of times. How would you explain the lack of this anomaly in ALL the EOS film bodies?

i guess the cost of the LCD and CMOS have already make up to 85% of the selling price...
let compare 1dmk2 and 20D both r 8 mega pixel but why their price r 3 time different? If u r in manufacture line then u know what is the price diff between 1.3 CF vs 1.6 CF...just like diamond in carat...same grade 0.5 carat vs 1 carat, their price diff can be up to 5 times more...

So maybe Canon try to cut cost to lower down the price for those FF fan...by mean of quailty? Who know?

they tried to save money by using a cheaper glue??? i though canon would be smarter than that....

In film time, the shutter count is relative low. In digital time, some people press the shutter release like using a machine gun.

My 300D mirror dropped off at 4000+ shutter count. Canon S.C. glued it back for free. It may be in its dppm range. For 5D, the number of user is relatively low and there are few cases ..... dppm wise is not low ....

Any way, Canon needs take a serious look at this reliability issue.

 

[miniUltraman]

I have used my 30D for about 15k shutter count... no problem at all. I don't think canon want to save glue... They should be well aware that the service (pple returning to service centre when mirror drop) will incur higher operation cost in the long run. :dunno: It might be a design flaw and a Canon's oversight (which probably has been addressed in the later batches) let's see

 

[shojibake]

I can't remember the specifics (hmm maybe it was here in cs), but i think it's because the mirror has less points glued than the other cameras.

ha....hopefully this glue on mirror problem is solved on the later batches *cross fingers*, i just joined the 5D club with a 2mth old grey set

haha.. I am sure it does (consoling myself).. cos mine is only 3 weeks old :bsmilie:

yes try not to use 3fps...

at least u guys dare to take the risk...

Wa so scary mirror drop plus rear element kana scratch, not to count the embarassment cause when your friend saw your Expensive Big Canon fail you in such a manner...how to explain?? Ummm .... Tell them "Its like that want la, Canon knows it, the whole Singapore also knows it as they are all CS member, very common problem la :bsmilie: Come on lets continue shooting, I have my Ixus with me" :sweat:

I am thinking of upgrading to 5D but now....Scary~:sweat::sweat::sweat:

it's time to ask Canon to wake up their QA/QC department liao...
