At Last after 3 years waiting..., I know I was right...

Just released Canon EOS 5D Mark II

and here is one of the feature related to my above quiries , taken from DP review:

Image processing features:

Highlight tone priority

Auto lighting optimizer (4 levels)

High ISO noise reduction (4 levels)

-->Lens peripheral illumination correction (vignetting correction)***

http://www.dpreview.com/previews/canoneos5dmarkii/

So for anyone who contribute an answer from many phisics theories, any excuse to accept devective lens vignetting

on old 5D, here are the truth.., even Canon Corp, add Lens peripheral illumination correction (vignetting correction),

and thats confirms my above matter, that vignetting on old 5D is something that need correction from manufacturer,

Well i was hoping to get this correction on old 5D, but, better late than never. :-)

Thank you all, lets close this case and its time to upgrade to 5D mark II.

Thank you for the response.

First thing first, I used Film Camera Minolta 500xi, with 20mm Tokina Lens since 1996. I never saw light fall off or Vignett.

In 2005 September, I bought Digital KonicaMinolta Dynax 5D (with crop factor, surely I never found such a thing (I used Tamron lens 11-18mm, with Hoya CPL lens filter attached))

In April 2006, I upgrade to EOS 5D, with 24-105 IS lens, and here I am in this forum.

Quote from Rafael:

"In consumer electronics, in general, the more money you spent the better equipment you get, and most important, better in almost every single respect. Better sound, better image, better reception, etc. "

I think this is a very common way of thinking most of customer, including Canon SLR EOS majority consumer.

quote continues..

In the photographic world more money doesn?t necessary means better pictures and I think that a lot of the new people taking photography come with this mentality and they just spend as much money they can without fully understanding the equipment they are buying and they end up feeling cheated by the manufacturer.

This is really new for me.

My friend is Nikonian, he upgrade from d70s to D200 then to D2X.

The more money he spent, the better the goods, the better image quality he gets.

I thought this also applied to Canon, but seems im wrong.

In Canon, more money spent, requires understanding (and accept)law of physics, and increase ability to work around the sophisticated equipment, also require PhotoShop as a compulsary Software.

Quote from mr Bishop.

I guess some people will never get it.

Thats correct sir, I just dont get it.

How come my 1997 full frame film Camera with 20mm lens did not vignet, and the combination of 2005 EOS 5D Digital full frame Camera with 24-105mm has light fall off and vignett.

Canon should put some kind of warning in the advertise or on the box said: Warning, Full frame sensor, Light fall off might occured with following lens kit: 1., 2., 3., etc.

Regards.

Thank you for the test, may I conclude, that all 3 canon full frame, combined with 3 lens 24,35, 24-105 lens are all vignetts.

This is a very very good proof and facts.

The only bad thing is, I found this fact AFTER I bought my Eos 5D and 24-105 IS expensive lens.

Now I understand the flaws is in the lens.

I deeply regret, I own 5D perfect body, but cannot paired with 24-105 lens, 24, and 35 because it vignett in large aperture.

No subtitute lens able to overcome this problem.

And my conclusion will be: Buying EOS 5D is my biggest mistake

(I didnt say 5D has a defect/problem)

Any one who wants to call me crying foul please wellcome, I am a foul, bought this camera, and i am crying because i spent US$ 3,500 and found these facts.

I dont care of 1DS Mark II or EOS 3 has same problem with these lens, because I have no more chance to own them, I spent all my saving to buy 5D and 24-105 IS, the best match from the best brand as the dealer advertise.

I thank you all for the valueable response. I can see all response has their own background, and point of view., and i need to try to accept.,

Its might be because my knowledge of photography is not that deep.

Since the first time i use film camera (konica minolta 500xi) for 8 Years, then upgrade to digital to Konica Minolta Dynax 5D, I never saw vignetting, (even using Tamron 11-18mm with CPL), so when i got assignment from an oil company to photograph their facility, i then look for the world best digital camera and my refference goes to Canon Eos 5D, with the best pair lens 24-105mm IS.

With this high class equipment my expectation is much better camera feature and far much better image, (it is indeed), but this vignetting issues suddenly appear.

And all refference suggest me the work around way to avoid this from shooting angle, to the usage of PS.

Intrested to what Bob mentioned, quote:

just bought a Ferrari and now I find you have to run it on premium gas and it only gets 12mpg, plus it's $600 for a tune up. My old Ford ran fine on regular, gave me 30mpg and a tune up was $49.95.

Why does Ferrari make defective cars?

The end result of the Car is: Ferrari can run lot faster and more convinient than Ford, so additional bucks will be allright for me.

The comparisson might should be:

My Cannon 5D run out of Battery in 400 Shots, and My old Minolta can last 800 shots. Canon battery is twice expensive than Minolta.

I will not consider this as a defect as long as the Image is 4 times better than Minolta.

What i feel was, My New Ferrari gets vibrate when reaching 100MPH and above, while my old Ford can run up to 120MPH with no vibration.

For 12mpg, plus it's $600 for a tune up, i would say this is a defect products.

And suggestions come to me not to drive more than 120MPH,

(thats for not to use below f8 and below 24mmFL)

Avoid take a Highway.

(avoid shooting pale blue sky as the top edges of the image)

Try to enjoy the vibration by turning the loud music, and use the vibration as the advantages of a music beat.

(to use vignetting as advantages of the image)

or If i want to look stylish, look for racing tyre not more than 4inch thick.(thats for thin Filter)

Or put a vibrator to compensate the actual speed vibration so it will not noticeable (for the use of PShop).

Apologize if any of my thought are unexceptable, it is really what i feel right now.

I guess i need to adjust my photography knowledge and try to understand that higher equipment required higher work around skill.

"Your camera doesn't have a problem, your lens has a "problem." If the problem were with the camera, stopping down or using a filter would have no effect."

Mike I tried to mount my 24-105mm L IS lens to my friend's EOS 20D, No vignetting at all, even using CPL Filter.

So its the Sensor of EOS5D is too large (aiming for full frame).

Canon should produce Lens larger than 77mm ring to overcome this i guess., what do you think.

Yes agreed Bob, so my conclusion is, when using Eos 5D:

1. Avoid shorter Focal length.

2. Avoid large Aperture

3. Avoid using regular filter, (look for thin one).

4. If still viggent occures, digitally correct the images.

For me, this is too much for a pro camera such EOS 5D.

My previous US$800 camera Konica Minolta Dynax 5D, using Super wide Tamron 11-18mm, f.4. With regular CPL hoya. No vignett at all.

But well, Full frame Camrea is my wrong choice i guess.<div></div>

Recently bought Cannon 5D with 24-105 IS lens, and found that vignetting are

noticeable in 24mm FL, this become more obvious when i attached CPL filter.

(See attached sample).

Back to Canon Reps. in my Country and Regional, and they all suggest me to use

Focal length higher than 24, or using Fstop higher than 8 to avoid vignet.

Anyone have any idea about my problem ? how come this Expensive Camera, has

this silly problem ?

I know this is the consequence of being Full frame, all the explanation and

reasoning i already receive from Canon Office, Asia Pacific region.

But Still, my simple question is remain un answered, how come Canon release

such "defect" product ?

No further response of my email regarding this from Canon.

Im a freelance Oil company facility photographer, and surely I need wide angle

photographs, but now my new Eos 5D are unuseable, vignetting from my point of

view are not acceptable.<div></div>
