The latest problem found with the 5D3 is the IS noise coming from certain lens-5D3 combination. It may be the case that all these teething issues (soft focus, write error, dead pixel) can be fixed by a firmware/software upgrade but it seems that there could be some hardware issues as well. I have not seen as many issues during the 5D2 release (black dot) and it seems that Canon has dropped the ball in the case of 5D3. Nikon seem to manage their new release better. Anyway this is an excellent example of never to be an early adopter. I'm putting off my purchase of the 5D3 and hopefully all these software/hardware bugs will be resolved in 2-3 months time by Canon.

It's not just about the s/n improvement, but the noise have a more pleasant film grain appearance with no banding

Well, I think its about time Canon make a statement about these issues, or non-issues and not let users and potential buyers speculate to death  :D

Man, what happened to Canon's QC?

So I have a the new 5dmk3 and a 50mm 1.2L.  I have been trying to get the micro adjustment on the lens just right, but but I figured out why it had been a bit confusing up to this point.  If I use the center point (or any AF point within the metering ring) I get spot on tack sharp AF on like 90% of the shots with 0 MFA.  BUT, if I use one of the outer AF spots I get pretty bad back focusing (like +15).  I thought maybe it was the body I had, so I just went back to the camera store and exchanged it for another body hoping that I would at least be able to figure out if that was the variable.  Turns out this body is exactly the same.  This makes me think it is either difficult for the AF to get a good lock due to the aberrations of the glass the closer you get to the edge, or something wrong with the lens itself (it is brand new and date code is uz0909).  I'm also just wondering if this is the price you pay with AF on really fast glass.  That is where you come in.  If you have fast glass (1.2) try checking the AF accuracy on center point and a more lateral point and lets see if we can come to a consensus.  I'm especially interested in 50mm 1.2 as thats what I'm working with.  I tested my 70-200 2.8 and it's pretty spot on with no MFA, on both center and lateral AF points.  I'll post a few test shots of my 50 when I get home later.

All AF points should work the same. Canon should look into this issue as well.

It's better to have more moderators than the so-called karma system. The karma system is open to abuse by irresponsible and immature members and can be unfair to many. Just my 2 cents

That is part of my disappointment. I have not used the DPP software because of the known issues. I'm using the Adobe DNG converter and photoshop and than maybe importing into lightroom, but going from the converter to photoshop is the best option at this time (actually its the only option). At the risk of repeating myself, I'm uncomfortable with the fact that the camera is released without any software that can process the images. Its a big leap of faith to assume that all is well with the raw images when cannon has not released software that can process them and the raw images where not available to the pre-testers either. Since I'm not using the DPP software it seems to be a hardware issue, but It could be operator error. Maybe the focus system is so advanced that it requires schooling to achieve acceptable results. I just don't know. Learned a big lesson, never buy a pre-released product. My father taught me to never throw away your old shoes until you have a good new pair. I forgot that lesson this time.

Have you tried ACR 6.7 beta?

Is the sharpness problem due to the DPP software problem, or is it due to lenses needing microadjustment? With my 5D2, all my L zoom and prime lenses did not need any microadjustment and it seems that the focus is factory calibrated to zero MA for most lenses. I use this MA method with great results so far I am just so surprised that the 5D3 has so much sharpness issue and I hope that it is more of the DPP software issue rather than a hardware issue. I am holding back my purchase of the 5D3 until the dust settles on this and a couple other issues with the 5D3.

An interesting development tonight.  I have been working at +6 all day on  my 50 1.2 and been pretty happy, thought I might see a bit of front focus this evening, set back to 0 and everything is totally spot on.  Will check tomorrow once the sun comes up if it is the lighting or if it just needed a bit of working in as the lens and body are brand new (makes no sense, I know).

What procedure did you use the determine the microadjustment amount? Did you use a tripod?

Some new updates from Bryan of TDP :

Clarification: The Canon EOS 5D Mark III is Delivering Very Sharp Images
I am getting a lot of email asking about the Canon EOS 5D Mark III and the image softness issue. Let me clarify what I'm seeing:
The Canon EOS 5D Mark III is Delivering Very Sharp Images
There is a softness issue, but it appears to be completely isolated to the Canon Digital Photo Pro software's "High quality" RAW conversion algorithm.
You can see the sharp 5D III images in DPP's quick viewer and in the Edit window with preferences set to High speed. The issue appears to be completely in DPP's High quality processing algorithm.
Canon has been in touch with me again this morning and appears very eager to resolve the problem. My personal expectation is that the problem resolution will be in the form of a DPP update. The 5D III appears to be fine from my perspective. I have no intentions of returning my camera - I'm having far too much fun with it.

Could be some kind of fungus growth on the sensor surface due to long storage? Return the camera for a sensor cleaning or exchange.

perhaps i am splitting hairs or maybe in this case eyelashes

first image is dpp preview crop screen shot
second image is acr6.7 crop screen shot

shot at f2.8 1/500 sec ISO 100 AWB
these are 100% crops
obviously 5D mk3 and lens is the 50mm f1.4 canon

ACR 6.7 is still in beta and hopefully the optimized version will be available soon.

What is the datecode on your 50L2?

UZ0909, why?

50L's with datecode ux and above have focus shift improvement. Just surprised you needed +6 microfocus adjustment.

Canon has no guts to post raw samples yet?   :D
