Okay, on a different board there is a photography discussion. An individual has stated the 5D and Canon full frame sensors are defective and stated so by Canon.


If this is related to anything other than the vignetting, I'd like to see references to the above.

For me, the full frame sensor on the 5D is superior to that of my 20D in more ways than just being bigger/more pixels.

I find that the 5D manages to capture a wider dynamic range. That if I take a picture with my 5D and the same picture with my 20D, I'll be able to pull details out of the highlights and shadows that the 20D just can't get.

I also find that the 5D manages to capture greater detail than my 20D. Little things like eyelashes and such are so much crisper on the 5D. This is also evidenced in the jpeg capture sizes. On the 20D (8.2mp sensor), my jpegs are about 2M in size. On the 5D (12.6mp sensor), the sensor itself is only 50% more pixels, but my jpegs are around 6-8M in size (3 to 4 times the output of the 20D) which I think is only further evidence of the detail within the image.

(disclaimer: these file sizes are based on converting from RAW to jpeg using RawShooter Premium - using the same settings whether converting from a 20D raw file or a 5D raw file. I have no idea what my native 5D jpeg file sizes are like as I only shoot raw with that camera.)

I understand the vignetting of the 5D will be greater than a 20D.

But is it dramatically worse than a full frame film camera?

i wouldn't use dramatic to describe it at all on most shots you can't see it at all.

In a word, no.
See my previous post. It may be *slightly* worse, but not noticeably.

According to some recent cameras put out by Leica (I think), there is a 'major issue' with the angle of incidence of light hitting the corners of the sensors which is aggravated by the reflectiveness inherent to digital sensors.

They have a form of built in 'anti-vignetting' technology on their sensors towards the edges and corners in one of their cams...

Blah blah blah...

Like Kirbic said, the proof is in the the images themselves. Too much splitting hairs on the net these days.

Vignetting is NO issue, only bad experiences I have had with the 5D and vignetting is I can no longer stack more than 2 filters on wide lenses as I could with the 20D but that is quite normal, as for vignetting in "normal" shot´s, I think that is just coming from people who like to take pictures of newspapers or brick walls just to measure how sharp their lenses are all over and not from people who just like to take pictures for the fun of it.

In short, no, vignetting is no issue on the 5D as far as I am concerned.

Yup but the response I got from SC was that it was because I used an tool designed to remove a "defect" to add an effect and that was why it was disqualified so I am pretty sure it´s legal to correct vignetting with the same tool in basic but don´t take my word for it, I am not 100% and would want a SC to answer this, especially after the new ruleset.

And here it is with, what, literally 4 seconds of manipulation...



Both are straight from RAW with only a resize.


Is removing vignetting permitted using the vignette filter in the RAW conversion tool in CS2 in Basic? We all know using it to add vignetting is not allowed.


Is it just me? Or does anyone else prefer the vignetted version of this image? Sometimes vignetting really works on some images to `frame` the subect.

Great shot Scarbrd

Not just you, I also like the vignetted version better :P

Me too - one of the things I love about the 5D is the ability to achieve a natural vignette. I can see how it might be frustrating for certain purposes (panoramics, product photography) but for everyday purposes can be very attractive.

I also agree that the sensor is incredibly good - it produces fantastic richness of tone and detail, and is extremely clean at high ISO.

The vignetting tends to occur most strongly at low f-stops and can be largely eliminated at smaller apertures.

With Panos, most blenders will eliminate the vignette. I found that AutoPano Pro (which can use smartblend) does this.

The key is to get about a 50% overlap between frames. That way, the darkest part (on the edge) will overlap the lightest part (at the center). Of course the top and bottom of the pano may be darker.

Would product photography use the vignette to highlight the object of interest?
