First post on the CR forums, thought i would say hello
I bought my 5D3 a week ago, and haven't really used it much as was waiting for the grip to arrive. I saw this post on the site and was shocked that there might be an "issue" with my new £3000 camera! I am based in the UK and can confirm my new 5D3 has the light leak "issue".
To be fair, I agree with most on here that it isn't really an issue unless you shoot as said in near pitch black with lens cap on etc etc Although, this isn't a 500D so when you pay the premium, and £3000 is a lot of premium, you really don't expect to get this kinda issue. Will the "issue" actually effect my photography (Weddings, Portriats and some landscapes) probably not, but I am one of these guys that when I know something isn't right it bugs me, not because its effecting my pictures as i am sure it won't, but knowing there is a known issue on something that is classed as Pro gear just bugs me.
With this in mind I took my camera back to the retail store i purchased it from, who were completely unaware of this issue so I showed them the post on the Canon website and then on my camera. He agreed the issue was there.
I was offered a repair or replacement, I then stated there is no point in a replacement as it will have the same issue, and I was not willing to give it in for repair as its only a week old and Canon haven't even said what is causing it yet.
The thing is, I have bought a lot of gear from this shop. I have a 5D2+grip, 24-105 L & 70-200 f2.8 L IS II all bought from them so add the 5D3 and its coming close to £10k so I feel I am within my right see what they can do to help.
The guy then called his area manager, who also checked the Canon website and basically agreed to replace my camera when Canon issue a updated/fixed model and to keep using the one until that time. And as a good will gesture they even gave me £100 cash
So I am more than chuffed, the non "issue" I am happy to live with on this model and if and when Canon revise the camera I have a receipt saying they will replace it for me FOC and I have a £100 in my pocket. Don't ask, don't get
