Bests & Worsts Reviews from Amazon

I have owned this camera for about a year now and just now getting around to writing my review, so I can say with 100% certainty how I feel. I have been a Canon shooter for a while and I am stepping up from a Canon 7D. The 5D is a little bit bigger than the 7D but both have similar build qualities. Some of the things that have changed from the 7D to the 5Dmkiii is the shooting function button, to change from Manual to Shutter Priority there is now a button on top that stops you from accidentally changing modes. Other than that, the ergonomics are pretty much the same (outside of the AF System). I had been shooting with the 7D for some time and I was really on the fence about making the move because I swear (and still do given I own both cameras) that there is not a significant difference between the images of the cameras when shooting at lower ISO's. When looking at both images side by side colors are slightly better, it seems like tonal gradients looked a little better but it was not huge. The problem I had with the 7D is that at ISO 3200 the images were so noisy they were about unusable, even with some cleanup things were pretty rough. I have shot many images with the 5D3 and I get great looking shots at ISO3200. The other huge difference is the AF System on the 5D3, head and shoulders better than anything I had ever used. The 7D was good and worked well and I had an old 1DMkii that had 45AF Points and was blazing fast but the new 5D was amazing and how many different configurations of the AF system you could set took me months to get used to but I love it. Sure the Nikon D800 has 36megapixels but I have always said, I will take a lower resolution shot that is spot on and crisp over a high resolution image that is blurry. Both in studio and out in nature this camera performs well and is very refined. I have shot with the Canon 7D, Sony NEX 5, NEX 3 and the new Fuji X-E2 and will take this camera every time. It has an AF System I can count on to be spot on every time, the ergonomics of it allow me to pull the camera out of my bag and change shutter, aperture and ISO without ever moving my eye out of the viewfinder and the LCD screen looks great in back. If I were going to knock anything it might be the slower burst mode but that would be about it. I don't shoot enough video with it to really talk about it's performance but I know a lot of people love it for that. ************UPDATE****************** 04-09-2014 After my last studio shoot I decided to send my camera into canon for cleaning (I normally have my camera sent out in January when I am shooting less to make sure everything is working right) and I get the estimate back that the there is dust between the low pass filter and the sensor and because of that the sensor needs to be replaced. Keep in mind at this point the camera had been used mainly in studio and never seen a drop of rain and is never kept without a lens or body cap on the camera AND the camera is only 15 months old. Given the light use and delicate care I take with my equipment and that I had a 7D for over two years working in the exact same environments with no problems, I feel this is 100% a manufacturers defect. After writing Canon several times they refused to address the problem and I was stuck with a 940 dollar bill. After the new sensor had been placed in the camera everything works good. To me it is crazy to think that needing to replace the sensor every year is a normal thing and considering Canon refuses to answer my questions regarding this repair I am to assume this is somewhat common. At this point I am never buying another Canon product ever again. There are too many great camera manufacturers out there to hold allegiance to a company that does not value me as a customer. I have owned the 20D, 7D and 5Dmkii. I own the 16-35 L, 24-70L, 35mm L, 50mm macro, 85 1.8, 100mm Macro L, 135 L and 70-200 L. Goodbye Canon.
