If canon 40D can show such impressive noise control at iso 3200.I dun know why they cant push it to 6400. Nikon D300 on the other hand had push the iso to 6400 , nikon really show great confidence & improvement with their new Expeed processor & CMOS senser.Let wait & see.
 

But sometimes Nikon may push their ISO a step too far for the sake of market purposes. I'd not be convinced until the samples come in.

In any case, why does dpreview use a crop factor of 1.5 in the preview pictures of the 40d? In any case, the image looks relatively clean at ISO3200 at the published resolution.
 

Canon SLR live view is simply impressive. wait till the they make 3inch flip out screen in future, den can take over head shots.=D
 

arghh... how much is 40D going to cost~!

You can connect to notebook to take over head shots. Wonder if can connect to my PDA running Windows OS?

It's be cool if it can link to PDA via the wifi function to provide remote viewing and remote control. ;p
 

Never be first in line....

Wait for Bug to resolve first, and price to drop......;)

Hi all,

What will be the foresee bug for 40D base on past experience? :think:

Assuming no stupid mistake from canon... The only drawback will be the x1.6 factor because using the older manual lenses ( leica or carl zeiss ) on this camera will suffer from a x1.6 factor.

Aren't all lenses, even EF-S lenses, subjected to a 1.6x crop?

yes, ofcourse all lens will suffer from x1.6 factor if you use them on this camera, no doubt about it. That is also the reason for the birth of the EF-S lens like 10-20mm, 17-55mm etc. so that the photographers get a wider coverage angle.

for a 10-20mm EF-S lens, it will make up to about 16-35mm ( round up ).

If you have a Carlzeiss manual 21mm lens ( very expansive lens ), when use on this camera, it will be equivalent to about 35mm ( normal angle coverage only ). Therefore, those people that has spend lots of money for the 21mm wide angle lens, will not choose this camera because they will not be able to fully utilise the angle coverage that they had paid for.

If the 40D camera is fullframe, then the 21mm carlzeiss lens will be able to cover a much wider angle instead. That is what I meant by the draw back. I hope I have answered Calebk correctly.

Ahh okay, now I see what you mean. (:

Is it? I through EF-S is for canon DSLR camera which was not FF and the focal length should be equal to those conventional lenses. That what I know for digital lenses.

Pls enlighten me if I was wrong. Any web site for ref.

Thanks

Even if it is EF-S lens, the focal length stated is a standardized value to be comparable with those full frame lens (EF Lens)...
Ever heard of the terms "xx-xxxmm equivalant on 35mm film format" ?

Reference web...can try this:

Listing of all EF & EF-S lens with effective focal length on different sensor size...

For canon bodies, there are 2 types:
EF mount and EF-S mount

if the lens is EF mount, then it can be mounted on both EF bodies and EF-S bodies.
if the lens is EF-S mount, then it can only be mounted onto EF-S bodies.
