and...I would understand if your pay for a camera which works flawlessly. Unfortunately I bought my in May, and so far, several European service actions hasn't fixes mine. Service in Germany even completely blocked one of my ,almost new, L lens. No one is willing to exchange the camera for a new one. I own 5 lenses (4 Ls) and that's why I cannot be happy with Canon. Paid really a lot for the brand new, faulty body, without good working AF, so I feel like I just waste my money right now. I completely agree that Canon is too expensive relatively, but mine was the most expensive camera I had ever bought. I wanted to buy some new lens next year but I just cant. Trust me-that is a real reason to be unhappy with Canon, the will just left you with faulty body if you are unlucky. The issue and the whole case is not only my problem as there are also 3 other professional photographers on the local most known Canon forum, who have the same problem with Canon. We have been just completely left with faulty gear. So my advice is double or triple check otherwise service will not help you in some cases.
When you say you are left with faulty gear, do you mean 1) it does not work as advertised and Canon won't fix it, or 2) that it does not work the way you want it to (but does work exactly the way it is designed)?
If the former (1), you have legal recourse available to you. Contact your government trade commission and ask them how to file a complaint. I seriously doubt that Canon repair really is leaving you high and dry - I want to hear the rest of the story.
If the later (2), then there is really nothing to be done, other than to either wait until Canon makes one works the way you want, see if Magic Lantern does what you want, or change to a different brand that may (or may not) work the way you want.
hey I am normal customer and photographer not a psycho, it obviously option no 1.
ad 1/ Do you think that 5d3 is designed to not achieving focus precisely? NO, and I think the same. Please have the full story (sry 4 my english-it not my mother tongue):
Bought 5d3 in May with 50 1.4 and 35L. I already own 24-70L, 70-200 L II IS, 135L, 85 1.8. The camera was faulty from the beginning. The focus points were completely misaligned. Took it to store, they advised to sent the camera to service in order to calibrate it with all lens. I was completely sure that that is not a issue with calibration but also with misaligment, therefore I made a detailed description. The body with lens was sent 2 times there and nothing was done besides standards calibration which obviously did not aligned AF sensors properly and did not adjust properly all lens. Sent it for the 3rd time and push them to exchange the camera. They did not exchange the camera but they exchanged the mirror box. It solve the misalignment issue but the lens was still not calibrated. After that 24-70 had problem with longer distance, 50mm was backfocusing for short distance. I also ask them to check a brand new 35L as I was sure it is soft so they should exchange it or fixed. They once more tried to calibrate all gear. After that 50 1.4 was still backfocusing at short distance, 135L started to miss at longer distance and 35L was still soft (nothing to do with calibration). They also stated that they checked 35L and it is fine. I was really frustrated with everything as it took 3,5 months and I still did not have a flawless body which I paid for. I took 35L for testing and you know what? A look inside and the glass inside was broken a bit, and it was for sure made during production. The lens was still just soft. So I was sure the service did not checked it seriously. I came back to store and bag them to exchange the lens, and they decided they will. The second glass was sharp! Besides that I still had focusing problems with body and other lens. First of all I checked once more the 50 and sent the test photos to service-they stated that it was calibrated correctly even if a show them bacfocused results(with lenscal). I though that maybe this is a lens issue so I sold 50 and tried 4 other 50mm samples from store to test at home. All were back focusing on short distance ( ca. 1m) . I did not buy any. So I thought it is camera issue. Next I decided to try other service so I bring the gear to Germany. They stated that the body is OK but some lens need calibration (already calibrated in my country). After that service activity my 135L is completely blocked (aparture) and I have err 01 (lens was rarely used). Also I found that I my 35L is not focusing properly with right side focus points (front focus on right sensors) so the second copy is faulty or maybe that's a camera issue once more (but german service did nothing with this lens) Other lens, which now works acceptable like 24-70 focus properly on side AF points. A. Trust me Canon service did nothing to REALLY solve the issue, and to satisfy me as a customer. They did what they know or pretend to but it does not solve the real problem. I know what 5d3 is capable of but mine is not. Its end of 2012 right now, and camera was purchased in May. Do u think I should be happy? I paid a lot for something that has't got its full value and I am left with the problem. That's the full story.
