Hi everyone, was just wondering if anyone can tell me which lens gives better image quality. Not worried about the versatilty of zoom and IS. Only Interested in knowing which one performs better...sharpness, color rendtion etc...especially at 400mm.

Thanks in advance

As in most cases the prime is slightly sharper and slightly faster to focus - thus making it a very common choice for birders.

Thanks John...always a good help. I wish there was a site that compared lenses against eachother andnot just reviewed them (although that obviously helps). Then you could just do a side by side comparison.

Anyway, Thanks again.

I haven't tried the canon 100-400, but the 400 f5.6 is a great lens with super IQ.
The photos at the below link were shot with the 400:

Edit to add that I did not change the color in these shots. Only a slight increase in contrast, cropping, resizing and a small amount of sharpening.

I don't know...
-> Is it just me but your older Sigma OS 80-400 seems to produce a much better picture (color + sharpness)?

Thanks for the help guys, they're great sites. IQ is vey impressive in the 400...especially given the price.

NHL, I thought I replied to your post the other day - must not have saved it.
You have picked one of my favorite gbh shots. I don't think I have done a better one - at least as far as the subject is concerned, (I was excited to get the lilies in the shot until I started doing post :angry. I think the light had a lot to do with the colors in that shot, and that was taken just before the 20D with the Sigma 80-400 went for a swim. It may have been an exceptional copy though. Anyway, I haven't used the replacement 80-400 much because I bought the 400 shortly after the ins. company replaced the Sigma.

May be you should try that Sigma again...

-> What is even more amazing was the original 400mm OS picture was shot @ 1/200s vs all higher shutter speeds for the EF-400 @ 1/400s, 1/800s or even higher on the 40D: The Sigma is clearly showing more details in the beak, eye and plumage... It might needs some white balance but again the color/saturation looks better to me on the Sigma than the Canon (this could be due to bad lighting... but then again the exposures are higher on the Canon's shots)

IMO you should do better on the 40D with that OS 80-400 especially with that higher resolution:
