Excerpt: As a 25 year professional photographer one one that has owned nearly 2 dozen Canon professional digital cameras, I can honestly say, this is the worst camera I have ever owned. If you rely on the focus points, don't count on them, as you won't be able to see them. They don't show up. They blend in with most backgrounds. There are numerous posts about the issue, however Canon will not admit there is a problem.
Excerpt: This is a great camera if you use it in day light in AI Servo mode. I am one of those few people who always have the camera in AI servo mode (and back button focus.. actually back button focus is not relevant to my reviw here)I shot a few Track/Field events and it is great since there are various options in AI servo mode to tweak the settings.
Pros: Fast / Accurate Auto-Focus, Good Image Quality
Excerpt: I'm having a bad experience with this camera. when I put the ISO on 12000 and above, I have this horizontal brown colour appears on the middle of the picture. I sent the camera to canon itself to fix the problem. however, after i got it from canon, they told me the problem was fixed but the problem still appears every time I raise the ISO to 12000 and above.
Excerpt: I can not see the difference in quality from the 30D and the 60D and this Mark III. The self timer seems to be on and there is a long 5sec delay between taking the photo and the click. And I cannot find out why this is happening.
Cons: Lag / Shutter Delay, Noisy At High ISO, No Viewfinder, Poor Image Quality, Poor Image Stabilization, Poor In Low Light, Short Battery Life, Small LCD Screen
Excerpt: I would like to think I could expect more from Canon. I've been a faithful Canon client for years, both my T3i and 5D Mark II have served me well. I recently took the leap and bought the 5D Mark III. The image quality is amazing, but I was a disappointed as the autofocus system doesn't work as accurate / fast as my Mark II (or T3i). However, that wasn't my only issue. After only two months of gentle use, the Sensor Cleaner broke down.
Pros: Good Image Quality
Cons: Bad Customer Service, Lack Of Features, Poor build quality
Conclusion: I am a hobbyist photographer; that said, I would have liked to have an on-board flash. I also own the 7D. I like the fact that with the 7D, I can use the on-board flash as a master flash (turned all the way off) for my 580 and 320 external flashes. With the 5D, I will need to purchase the speedlite transmitter to accomplish the same task. I would also have liked it if Canon would have made the LCD screen tilt, like the 60D.
Excerpt: As a press photographer I shoot then send, shoot then send....making quick edits throughout the day then a more thorough edit when the shooting is done. The camera wouldn't allow this, it would lock up with an error and the only way to continue shooting with the same card would be to reformat the card in a different camera. Not realistic for me, not acceptable for the price. I'm sure it will be fixed soon enough but for now..
Pros: Good Image Quality, High ISO Performance, Large Clear LCD
Conclusion: body cap on, eyepiece on, meter still reads something, it should be completely dark inside the body. with LCD top panel light on, the metering changing. in real shootings -- tend to under exposed in the varied light source conditions, like sunlite and shadow, window light and dark room etc. weather seal seems not that good, with laser beam tests, can see possible light leak from top to bottom.
Pros: many features that are for events/wedding shooters, low iso iq
