Hi, i am looking into getting a 5d mark ii for video feature but am not sure if i should get the midgrade camera the 7d. Would anyone share the differences with me as i cant seem to figure out which is better. The 5d has a full frame and the 7d is the cropped sensor. What does that all mean. Thanks in advanced for help!
 
Full frame means you get your full image and crop means its a bit less. So for example,
24mm becomes 38.4mm.

To get this you just take your lens zoom number, and multiply it by 1.6. That will give you the number that the crop will see.

If I am wrong, anybody feel free to correct me?

In terms of video, another important difference between the 5dmkii and the 7d is that the automatic gain control (AGC) for audio on the 5d can now be turned off.

You will be able to achieve a narrow depth of field easier with a full size sensor. You will also have increased low-light shooting ability.

The 7d sensor, on the other hand, is actually closer to a 35mm film imager than the 5d. And using an EF lens on a 1.6 crop body enables use of the lens's "sweet spot", while avoiding use of most lenses's areas of limitations and flaws.

If you are considering using the camera for stills as well, you will want to closely compare the two for strengths and weaknesses. AF, low light, speed, and protection are some of the considerations.
 
I shoot with the 5D and 7D all the time. Here is a quick rundown from my perspective.

5D:

Gets shallower and wider than the 7D on a given lens. A bit less prone to aliasing/moire and overheating.

7D:

Gets a fair bit longer than the 5D on a given lens (the 1.6 crop) - better for sports or longer lens stuff. Can shoot 720 - 60p, great for overcranking. Aliasing and moire are a bit worse at 720p. The biggest plus with the 7D is you can monitor HD out while recording, the 5D downconverts to 480 as soon as you hit record - a real bummer.

All things being equal the cameras are pretty hard to tell apart. Both are pretty popular rentals in our area if that's a consideration. The 5D is popular because of a bit of name recognition and the ability to get crazy shallow if desired. The 7D is popular because it still gets really shallow and is a bit easier to work with because of the monitoring.

I should also add that the 60D has pretty much the video performance of the 7D plus a swivel screen and manual audio. Worth a look if you don't need the 7D's sturdy build and weatherproofing.
 
It's symantics, but 7D is not a midgrade camera. All canon's with a single digit are their pro-line. 2 digits are mid-level and 3 digits are the entry level. Different digits within those categories denote things such as sensor size, etc.. as noted in this post.
 
Here is my opinion as I've shot with both on many occasions.

5Dmii
- Stills camera from the start
- Stills are much better in lowlight than 7D
- Video better in lowlight as well (not as much of a difference as stills however)
- FF sensor means wide lenses are actually wide
- No dedicated start/stop button
- Camera on/off switch in weird position
- Only shoots 24p (no 60p at this point)
- manual audio control
- down-converts HDMI signal to 480 as soon as you start recording, therefore theres a 2 second period where your external monitor will go blank after you hit record
- Rolling shutter seems to be more evident (im assuming because it takes longer to scan the larger sensor)
- Larger sensor means super shallow DOF...to the point where it can be very hard to control your focus
- obviously, a higher price

7D
- Designed from day one to also have video capability (had dedicated stop/start button and live view switch)
- Locking on off switch right by the scene selection dial
- Shoots in multiple framerates (24, 30, 60)
- No manual audio as of now
- Crop factor makes super wide shots somewhat impossible (without buying APS-C lenses which cannot be used on FF sensors)
- Stays 1080i throughout entire preview/recording process
- Autofocus much better than 5D for stills
- Shoots at up to 8fps for stills (much faster than 5D and great for sports photography)
- Not quite as good as 5d in lowlight situations
- Less rolling shutter artifacts
- Weather-proofing is excellent
- Has two of the Digic 4 processors (v.s. only 1 in the 5d)
- Cheaper than the 5D

What do you plan on using the camera for? That should be the first question you ask yourself. If its just video than are you shooting in lowlight situations a lot and can you sacrifice slow motion 60p?

Heres what I'd do...if your wanting to shoot stills along with video and have any intent of shooting sports go with the 7D. Your investing in a newer camera and one that will work just fine. Both are very similar in their abilities.

On the other hand, if you have the money the 5dmii is Canon's most popular camera. There is a reason that many professional photographers and filmmakers are using it for their trade.

Hope that helps,

Jon
