Summary: After testing it out I realized I needed to upgrade the firmware by sending it it to Canon and have the focusing re-calibrated. It seems as though this got neglected by the past owner. Not a nice thing to have to do after spending that kind of money and then paying for shipping and insurance $$$! It was also missing the english "quick guide" so now I have to carry around the thick manual until I totally dial the settings.
Summary: Great camera for shooting action in low light. Low noise at higher ISO's. Easy to use menus and buttons are located in the right places. LCD could be a lot better. Not as sharp as i would like. Neck strap quite pathetic for a camera of this calibre and price. Overall it is a great piece of photo equipment.
Pros: Comfortable Controls, Easy To Use, Fast Shutter Speed, Great Image Quality, Strong Construction
Summary: I had the mirror problems and AF issues with my first Mark III, but that is resolved and it hangs from my other shoulder. My new Mark III, with my personalized menu settings for equine sports photography is perfect, absolutely perfect. There are exposure issues for me if I enable spot metering with AF and meter off a lighter surface, then track a darker object in that it still blows out the lights. Other than that, I only have only wonderful things to say.
Pros: Ability to customize menu, Bright LCD, Comfortable Controls, Fast Shutter Speed, Great Image Quality, Strong Construction
Summary: Aloha, We like the camera and are overall very please with the decision to purchase this unit. We picked up this unit to replace our 2+ year old 1ds Mark 2. Based on the current global economic situation we could not justify spending the extra gold for the 1ds mark 3 and opted for the 1d mark 3. The large monitor is nice however it could use a little tweeking. We have decided to stick with the 1ds Mark2 as our primary camera and use this new 1d mark3 as our back-up.
Summary: A solid workhorse of a camera - this one is built for speed and durability. The batteries last long, the dynamic range is more impressive, the color depth is beautiful - my only complaint is the auto-focus. In bright sunlight this camera just doesn't perform - a burst of 8 images produces 1 or 2 tack sharp images and the remainder are slightly off. Good enough for small prints but if you want a 20x30 it's going to be noticeable.
Pros: Bright LCD, Comfortable Controls, Sensor cleaning, Strong Construction
Summary: Overall I really like my MarkIIIs. Color seems almost as nice as my 5Ds. For the money, you'd think it would be a bit better, IMHO. Also, the little thumbstick doesn't work as a quick-set for the focus point. What's up with that, Canon? Overall not as efficient to use as my 5D, but I still use it more than the 5D. Has a great feel to it.
Pros: Bright LCD, Comfortable Controls, Quiet, Small Lag Time, Strong Construction
Cons: 5D has better color, Difficult to set Focus Pt
Summary: A good camera with great features. Colors are vivid and images are sharp. I have had some great images come out of this camera. BUTAI-servo focusing and be a huge problem if you are tracking fast moving subjects in almost any lighting conditions. Expertise: Semi-pro Problems Encountered: I love the camera, or I should say I want to love the camera, but it is safe to say it is a love hate relationship.
