Its all just speculation... those rumour sites are full of every possible permutation so at least in the end they will have been right... somewhere!
As a pro wedding/sports photographer, yes! Weather sealing and AF are absolutely vital, neither of which I don't think the 7D comes anywhere near close to the 1D series. (Haven't tried a 7D for AF, but it's nothing ground breaking from what I've read)
From Canon website on 7D
"The magnesium alloy body offers weather sealing equivalent to the acclaimed EOS-1N"
And the AF:
19-point cross-type AF system
A newly designed AF sensor with Zone and Spot AF modes gives the photographer new ways to select AF points. All points are cross type with the centre point offering both f/2.8 and f/5.6 sensors.
Here is a graphic showing the weather seals of the 7D. It is missing quite a few important seals that the 1D-series has.
Weather sealing is red and the green is reinforced body strength.

It's missing seals around the main click wheel and joystick on the back along with missing seals on the shutter button and main control wheel above the shutter button.

I looked here and it's listed as "good" not extensive. Honestly everyone seems to be getting sold on the weather sealing of the 7d thinking it is on par with the 1d series cameras because it has weather sealing on par with another of the 1 series (the N)...it's just not.
Apparently the 1n series wasn't even that well sealed in comparison to the 1v/d which places it somewhere around the xxd series in so far as sealing as best I can tell. Meaning it will survive a basic drizzle just fine, but it can not be soaked..period. Sorry but I remain unsold on it until someone gets one drenched.
Sorry dont wish to appear rude but imho this is getting out of hand!!
If you buy a car you do not compare a £15k Ford with a £30K Merc when making your buying decision so why do the exactly that with a camera?
The 7D is aimed at enthusiastic competent amateurs (eg me!!) the 1D at pro's (eg a lot of you guys)
Soorry but felt it had to be said
* Images ~16MP
* ISO 50-26500
* Liveview AF not up to fast sports use, but very usable otherwise
* Video as with 5D2
I am not saying that fact is true, but it would make sense - certain areas of "pro" photography could get really iffy if your equipment could shoot video, because you don't have the rights to shoot moving pictures, only stills.... premier football or F1 for example...




Edit: Actually thinking about it, if the sensor was sat further back in the camera body, could a larger sensor be used? Or does it not work like that?

I would like them to get rid of the video and concentrate on the camera.
Lens Equation: 1/u + 1/v = 1/f
u= object distance
v= image distance
f= focal length
You are thinking of changing v which would put the image out of focus with the current ef lens range as it would not be able to get the image in focus on the sensor, or am I wrong![]()
same here, i would hate to see video on a MKIV complete waste of time for a sports shooter. If you want video buy a videocamera
Video is here and here to stay so just get use to it.


hehehe i love this.....
All these tantalising specs, rumours, whisperings in the corridors of canon......
jeeez....you can have all the specs you want but if you cant see a decent picture you may as well be using a pinhole camera made from a bake bean can,LOL
Some of the best images i have ever seen are taken on Old olympus / nikon / canon etc cameras that pre date digital.
good camera doesnt mean good photographer (or largest p**is) LOL...
Still...that said.. if i had a few millions in the bank id be first in the queue.....![]()
Video is a complete waste of time on a DSLR and as other have mentioned having a PRO body aimed at Sports Togs (And the Canon Pro bodies are aimed at Sports togs) and others wouldn't go down well if it had video. It would cause a major headache with licencing etc. As they keep them separate from stills and video
I just can't see where a photographer is going to have any use for video, the grounds are already saturated with video cameras
I don't know but is the v= image distance not different on the 1.6 crop camera, and that why we have the EF-S lenses (Short Back Focus) yet the EF lenses still work on these. Maybe it works the other way too or would we need EF-L lenses (Long Back Focus)![]()

19 AF points? Lame.
19 AF points? Lame.
I agree.I find one to be more than enough at any give time![]()
Is it worth copying this into the other thread guys? I don't mind either way but there's no point in having two rumours threads![]()
