This camera allows me to shoot in lower light at faster shutter speeds. This should come in very handy as the racing season is about to begin. So many races are now night.

This camera is meant to compliment my 5D Mk II. I'll use this for events that need speed (like sports and special events) while the 5D Mk II will handle the landscapes and portraits where the full frame will come into play. I have been shooting with the 1D MK IV for a week and love it. It is solid, can handle being in not so nice locations and can keep up with you. The magnification aspect of the sensor is welcome and extends the reach of my lenses. I would highly recommend purchasing an LCD protector (my choice was a Giottos Optical Screen Protector that is rigid glass and color balanced) as this will save you from future headaches and expenses. This camera is blazingly fast and helps me exceed my potential.

So far I am disappointed. The camera is in the Canon repair center as I write this. At first it seemed okay, but the pictures have gotten worse daily. Hopefully Canon will rectify this.

The camera is as advertised, with outstanding high-ISO resolution. It's an upgrade from my oft-used 1D Mark III, so there was no "period of uncertainty." Just pick it up and shoot.

Replaced a 1D Mark III. Really loved the Mark III but this is even better. My favorite is the fast shutter speed and ability to take up to seven bracketed images automatically. In a pinch I can take a three image bracket in less than a second using hand held. The only thing that would be better about this camera was if it was less expensive, but as usual you get what you pay for.

I've now shot 30,000+ images with the Mk IV. I'm still amazed. I'm able to shoot in extreme conditions. I've found a new ISO at 8000 I really enjoy when the lighting is poor. And, I just made a poster from a print shot at 12800iso, f2.8 @664 shutter speed. It's real easy to adjust the exposure compensation to take out shadows when shooting against the sun. Something I'd never do before.

It is really hard to assess everything this camera does. I find myself often basing my comparisons with perfection with this camera, where past cameras were given a lot of slack (they were just cameras).... So it is quite a machine. I've moved up from a Mark II, and I think the most noticeable difference is image quality. It feels exactly like the 6 year old mark II... which causes my wife to wonder why I spent 5k on the "same thing"?

This camera is a beast. 10fps will rock your world. I shoot a lot while on the move - in, on and hanging off all manner of transportation in developing countries. Not missing 'the shot' makes this investment very much worthwhile. The low light capability is incredible for both stills and video (which when shot with a 24-70 2.8 blew my mind in regards to quality). She's not cheap, but if you're in the market for pro level quality and pro level options, you won't be disappointed.

We moved up from the 5D MKII because of the fps, and very happy we did. Much better then we hoped for.

Ordered mid-October, received from Adorama last week with as much anticipation as anyone else who had one on order. Other "pro" bodies to compare this to is my 5D (original version), 5D Mark II and a 1D Mark III. I still own the Mark III and the 5D Mark II.
After a week of shooting, setting up my custom functions and scrutinizing over Canons 122 page "white paper", which goes over every single feature of this body (the "white paper" is downloadable on Canon's website) I will give you brief rundown as im sure reviews will soon be pouring in as these are shipped to consumers.
I see some substantional improvements over the Mark III, enough to justify the pricetag...
1) low light shooting up to ISO 12600 is simply amazing. ISO above that are really not something you want to use unless absolutely needed. Even with noise reduction, pictures at the high three custom ISO's arent really practical. I believe more of a marketing point than a useable feature a professional would use.
2) HD video at custom frame rates. I personally am not an HD video fan on pro bodies...I have a Canon full HD camcorder for that...but I would be somewhat disappointed if the Mark IV didnt have HD video.
3) Autofocus system retooled with 39 cross-type AF points. Customization of those AF points and their expansion is available as a custom function.
4) A new feature, which I can not belive how much I love is "Auto ISO". You set ISO to Auto, and set camera to manual. You choose shutter speed and f stop, camera figures ISO automatically for proper exposure. This is a godsend in changing light conditions and is amazingly acurate. The only downside, which maybe will be addressed in a future firmware version, is that you can not manually adjust exposure, using the quick control dial in 1/3 step increments.
4) AF point actually changes whether you have camera in landscape or portrait mode. No more changing AF point yourself when shooting portrait. There is a sensor in body which automatically changes AF point to match the cameras orientation. This point is of course programable by the user easily. (Too Cool !)
5) Improved JPEG workflow with such features as "Auto lighting optimizer" reducing over/underexposed shots, and even inbedable copyright infomation which can not be programed directly from the camera.
6) VASTLY improved 3" LDG with 900,000 dot viewing and glare reduction. The same LCD as the 5D Mark II which I love.
...now for my only minor gripe. There is already a firmware update version 1.06 to address AF issues with slow moving subject moving toward you. Canon calls this an "enhancement", hoping to steer clear of the Mark III AF fiasco. In their defense, my body came with the new version already installed so a firmware update was not needed on my part.
---OK....is it worth moving up from the Mark III or the 5D MII....in my humble opinion yes. The update sensor, (which is a technological wonder), amazing low light ability, reworked AF, HD video and a new LCD which is simply amazing make this a no brainer for me. Too bad my Mark III's resale value tanked thanks to the Mark IV. Guess it will make a nice back up body.
