I've had mine since July and I have taken macro shots at ISO 6400 and some wildlife shots at ISO 5000, without any noise reduction. The noise is visible if you look hard enough in the darker areas, but certainly not what I would call distracting. At ISO 100, I can't see any noise. Bear in mind, if I don't expose correctly, then I retake where possible, often even if it's only half a stop out, then do as little post processing as possible.The only real 'problem' I have with my 5DMkIII is that the RAW files seem very noisy even at base ISO (whatever the base ISO actually is - 100, 160 - I have read somewhere that 160 is supposed to be less noisy than 100). I always have to move the luminance slider in LR4 to around 50 to eliminate noise and that inevitably results in loss of some detail.
I'd be very interested to hear from other 5DMkIII users as to how much noise reduction they routinely apply to RAW images shot at base ISO and how the 5DMkIII compares with previous bodies that they have used in that respect.
I'm just wondering if the level of noise I'm seeing in my RAW files at base ISO is just a characteristic of the sensor or whether I have a dud and should return it to Canon whilst it's still within the guarantee period.
That doesn't sound right at all. I just sent back a 6D for other reasons, but ISO was very good and 400 required no noise reduction at all. My 5D3 arrives Friday and it had better be similar if it doesn't want to go back where it came from. I'll post when it gets here.
Thanks - I'll be very interested as to what level of noise reduction you need to apply to the RAW files from your new 5DMkIII. Mine was one of the first available in the UK, so I'm wondering whether that might have anything to do with it i.e. whether later serial numbers have better sensor performance.

Topic: Am I the only one without 5D3 Problems? (Read 3897 times)
Canon 5D MkIII, 7D, 300mm L IS f/2.8 and a few other L's
Here is what I love about the 5D3 ....You've summed it up very well. I don't have problems with the 5D3 either, other than the black AF points. It is the best wedding camera I've ever used. DxO doesn't shoot weddings, so their ratings don't reflect important camera features that matter to me. I have lots of D800 files from a 2nd shooter and they are wonderfully detailed (if you make giant-sized prints), but the color is not as pleasing as from the 5D3. And Nikon doesn't have the medium raw file size option or the new flashes with built in radio.
Am I just oblivious to problems or a lot of people just suffering from "the grass is always greener" syndrome because of the rave reviews the D800 gets on websites like DXO?
