7D vs 5D?
on Jun 24, 2011 at 2:56:41 am

I can't make a decision between the two...

Don't know if I am right about this but 7D has more Depth of field and has a crop sensor unlike 5D who has more shallow DOF but has Full-frame sensor, also heard it makes it harder to focus with.
I have a hard time visualizing the difference between these two camera's..

I'm shooting in tight spaces but would like to capture more deep DOF. Would 7D be a better choice in that case? Yet I also like the full-frame look of 5D...

Between the two what are the recommendations or any comments?

Thank you kindly in advance!

I won't make a recommendation between the two cameras, just point one thing out... a larger sensor doesn't necessarily only give you a shallower depth of field. Rather, it gives you a more controllable depth of field. That is, you can have a DoF that's deep or shallow, it just depends on your lighting, lens choice, and f-stop. But the larger sensor lets you get a shallower depth of field when you want it. It doesn't always automatically saddle you with super-shallow DoFs. It's pretty much the same situation that 35mm SLR still shooters (back in the pre-DSLR days) and 35mm cinematographers have been used to for about 100 years now.

There are two issues to keep in mind in choosing between the 5D and the 7D: field of view, and depth of field.

Field of view: go to the excellent lens comparison page by Abel Cine Tech, http://abelcine.com/fov/. You can see that the 7D has a field of view close to that of a 35mm motion picture camera framed 16:9. (I suggest you set the lens choice to 25mm for a clear comparison.) The 5D has a substantially wider field of view at the same 25mm lens that the 35mm film camera or the 7D.

To match the field of view of a 35mm film camera shooting with a focal length of 25mm, on the 5D you would need a 36.2mm focal length lens.

Which leads us to the second issue: depth of field. If you are matching field of view, then on the 5D you will need to shoot with a longer lens than on the 7D. And the longer the lens, given the same distance from the subject and same f/stop, the more shallow the depth of field.

If you are shooting in tight spaces, then you may find you like the larger field of view of the 5D.

The depth of field of a 25mm lens is identical regardless of format. If you put a 25mm lens on an 8mm camera or on a 65mm camera, the depth of field at a given distance and at a give f/stop is identical. The field of view, however, is vastly different.

From your description of how you would be shooting, it sounds like the 5D will work better for you than the 7D. (Assuming the cost difference is no obstacle....)

I would have went with 7D or 5D a few months back, but they do not get upgrades like the prosumer right below 7D. Its generally about the glass anyway. The 60D articulating screen is very nice, but NOT for what many would consider the plus. I like it to protect my screen when I am not using it. Sure you can get screen guards, but as with Iphone I hate some plastic garbage covering up the beauty that is my screen. Plus internal updates hardware wise were latest and greatest. I do more video than I do stills is another reason.

When 7d/5d get their upgrades, I will probably step up to 5D, until then I am happier than a pig in mud with my 60D. I also love my Sigma 2.8 70-200.

"We'll fix it in post" I love to hear that.

I was linking this site in another thread about 60D vs 7D and it will get you thinking when you look at this comparison.

60D vs 5D

75 vs 72, 3 points worth 1800 bucks? You decide.

5D will give you more color detail and less video noise when cranking up your ISO. 7D has more control over video settings and allow you to shoot 720p at 60fps.

The 60D has the same guts as the 7D, with the plus of a flip out screen.


Personally, I would only purchase a DSLR for a B-camera. If you have the budget, I would recommend the Panasonic AF-100 or Sony NEX FS-100U.
These are Video Cameras with the advantage of using your DSLR lenses. Much better camera images with not issues of Rolling Shutters, banding,& jello effects you get with the DSLR.
