7D, "100% field of view" is NOT true

I have tested my 7D OVF frame coverage.
I concluded that 7D's field of view is under 98%, not 100%.
I'm very disappointed.
I think "100%" frame coverage means at least over 99% not under 98%.
I think "100% frame coverage" is an exaggerative advertisement.

I will wait for pop photo who actually have test equipment let us know the true coverage. Exactly how did you come to this conclusion. Eyeballed it?

Re: 7D, "100% field of view" is NOT true

isn't it only true for a certain lens, something like 50mm f/1.4 focused at the infinity?

Re: 7D, "100% field of view" is NOT true

I don't have enough equipment for testing frame coverage.
I am not professional photographer nor engineer.

I tested whith my eye, so I hope somebody test 7D's OVF frame coverage with precise method.

I think that is only true for the VF magnification not the field of view.

Re: Pixel-peepin... field of view, Great!

I hope I understand this. I want whatever I see on the OVF to be what on my photo. Well, the logic should be ?

Otherwise, the advertising is a little misleading ...

This is CIPA(Camera & Imaging Products Association, Japan) guide line.
See page 13, view finder-coverage/field of view.
I did my test under that condition.

Clearly yours is defective. Return it.

your 3rd post LOL

You are worried about a 2% difference? I doubt you can even measure it to within 2%. What method did you use?

Jeez, a new camera and everyone pops out of the woodwork.

Re: your 3rd post LOL

English is not my native language. So I have not posted here often. Just read posts.

As mentioned, I'm not expert. But, I think specifiaction and advertisement is a important promise between manufaturers and consumers. I think the Gap of the cost between 100% and 98%.

Maybe that problem is only applicable to my camera.

I took lots of pictures to find out the field coverage of my camera. But there are limits to my abilities.

If have time, I hope other people test it.

Re: your 3rd post LOL

Agreed. It is important to hold all manufacturers to task. If Canon is making claims that aren't true, that is simply not acceptable.

And for the record, I own a 7D.

Re: your 3rd post LOL

Well, to refute your claim, I have found that with a 1.4 50mm the viewfinder is truly 100%. In fact, I can literally place my right eye in the viewfinder, and open the other one and see almost normally with no difference in the images from either eye.

I didn't quite believe the 100% either at first, but that experience shocked me!

(And yes, I have also compared on computer screen to LCD to viewfinder)

what Canon said ->

The spec on the Canon web site says "approx. 100%" and the manual that comes with the 7D says "approx. 100%". Anyway when I look through it, the VF on the 7D is AWESOME compared to my old 30D, 350D and 300D.

Wake up..

Have you ever found any advertisement that was 100% true and not at least lets say a bit optimistic???
Well I haven't.

And here 100% are maybe optimistic (or measured on some special conditions which should be found maybe on the datasheet. Unless you don't the test with the exact same conditions/lenses etc. you mighht not get the same result.)

I did a quick test and it sure looked like 100% to me.

In your desperation to find fault.....

this is the most absurd thing to pick on. It shows you are ill suited to photography which is essentially a creative medium (unless you are a scientific photographer). I have successfully managed to compose photographs with cameras of leeser OVF coverage than the 7D as I have learnt the limitations and can overcome them without any trouble.

The problem with people today is they don't want to have to think for themselves. It will soon be the case that you will want a camera that you tell to go take a picture and it does without you needing to get out of your bed.

Pathetic.

Re: In your desperation to find fault.....

I don't know why you are so generous to 7D, I think "specification" must be precise. In Japan, lots of people are discussing about 7d's OVF field coverage issue.
