wow but out of my range anyway. Just got my canon 5D so me happy.
Chris

Wow...looks very impressive....live view LCD, dust removal, 10fps, and 14bit data!!!!.
The only thing I don't understand is the move to a 1.3x FOV....will this necessitate a whole new series of lenses???

Not a move..the1D mkii also has a 1x3 pov...

All EOS bodies  still take the EF range in len's...apart from a few that accept the EFs range too.

Sounds an exciting release and at the right price point if the Dollar to Pound or Euro stands up... I think the 10 fps and improved focus points are the real selling points here... Yeah Jim is right the 1.3 FOV is the same as the previous 2 versions, and only the EFS lens would be incompatible

:drools: 

well my 30d is serving me well enough - when i win the lottery i might get one. Thing is i dont play - have to be in it to win it as they say :)

i wonder how they measure the 10fps... because obviously if you have say a 0.1 second exposure then it wont be 10fps, because there must be a time between closing and opening again.

1D mk ii  series etc have dual processors built in...and a huge buffer to help.

@nameless/danob....regarding the 1.3FOV...thanks, I didn't know that...thought they were 1.6X!

I guess my question is still valid though;
Canon DSLR's now have a 1.0FOV, a 1.3FOV and a 1.6FOV....so, how can one expect the same degree of performance out of a lens designed for the 1.0FOV (FF) vs the 1.6FOV (30D)?

Yeah it may seem odd but it is only the  Field of view so you get a crop of the full frame 1.3 being less than the 30D 20D AND 10D all at 1.6 it may well be the reverse of what you may expect in that the full frame sensor is more critical of the optics as it is the edge of the frame where sharpness is the key factor and will be less good there on lesser lens... the fact is that the 1.3 and 1.6 sensors are getting more of the central sweetspot...

 I think the Canon engineers whould have loved to have made a full frame sensor but as Jim has said they have add to add a further  processor and increase the buffer size to enable the 10fps it was not  possible at this stage to have been able to move say 13 megapix at that speed... But the technical specs with the dual processors seem to pave the way for 20 megapixels so I would expect the new 1DSMK111 to at least that with maybe 6fps as well!

@danob....yes, that was exactly my area of concern....both edge of frame sharpness and edge of frame light dispersion.  
That was what prompted my question, as many lens manufacturers have designed lenses specific to the sensor size....so, in essence a lens designed for a 1.6Xfov will not perform optimally at the frame edges if used on a 1.3Xfov or a 1.0Xfov (FF) sensor.

Regarding processors/data transfer.....yes, that's a whopping amount of data to be moved at 10fps....impressive!!!

just thinking out loud here - isnt the retina of the eye a convex "sensor"? why dont they create something similar - then all that lark about light not hitting the edge at the same angle as the centre would be nulled...

obviously you would need a new set of lenses to disperse the light like that .. it must be somewhat optically possible or do we actually see slightly out of focus on our periphery?

Gradient: the 1Dmk2 has 8  1/2 fps....only once did I manage 9 :)

John (Gradient) I think you may find that the lenses designed for 1.6 crop sensors do not fit on the cams that have larger sensors.  These lenses in the Canon range are the EFs lenses and will only fit on the 1.6 crop cams. 

Lenses designed for full frame sensors offer the advantage of using the 'sweet spot' at the centre of the lens when used on smaller sensors and are compatible with the whole range of cams whatever their sensor size.  

The exception to that in the 1.6 crop range is the Canon 10D which will not accept the EFS range

Thanks for the education guys!!!
So to summarize, if I now understand corrrectly;

MarkII, Mark III, 5D and 10D will only accomodate FF designed lenses;
Digital Rebels, 30D and 20D could handle the FF design or the specific 1.6X design.

Similarly, the 1.6X lenses can not be used on the Mark II, Mark III, 5D or 10D.

Right?

Interesting - I wonder why they went with 10.1MP? They've got a whopper of a camera that's 16MP, and another doozy that's the 11MP - wonder why they decided to go a little smaller?

Maybe it's for the faster shooting for sports, photojournalism, etc.? (yes, I'm typing out loud and even answering my own question in a mental freeflow with a keyboard... I'm weird like that...) Nikon did that when they came out with the 4MP one (when they'd already made 6.1MP cams) because their processors and buffers could keep up better.

As for the lenses - I thought you could use ALL Canon lenses with ALL Canon cameras - they'll just have more or less variants of crop depending on image size and rear projection diameter. But I was under the impression they all WORK with any Canon DSLR you've got?

@T1;
Yeah, I think you nailed it....speeeeeeed!
Don't think they were able to get 16MP data processed and moved into that buffer at 10fps ( the Mark II can only do 4fps).  
So the best they could move at 10fps was 10MP of data....either way it's still a very impressive transfer rate!

**MarkII, Mark III, 5D and 10D will only accomodate FF designed lenses;

ALL** EOS bodies will fit  ALL EF len's...regarding the POV

The EF's lens range will only fit 300D, 350D, 20D, 30D, 400D..these bodies will accept EF range also.

  We all ought to be awarded a diploma in Canon Product knowledge now

Our eye has a fixed focal length for all intents and purposes. The curvature of your eye corresponds to this focal length. For a camera that would mean that for every focal length you'd need a different sensor, or a sensor that can be adjusted to match the focal length.

@Richard....

"We all ought to be awarded a diploma in Canon Product knowledge now "

Do you think they might send us a Mark III along with the diploma?

I have the 1DMKIIN and at 8.5 FPS it's a machine gun but that 10 FPS would be like a modern day gatling gun LOL

Only lenses that do not fit the D series are non L's anyhow I think.  Not sure if they make a L EF-S lens.

If you want to shoot landscape then get the 5D, if you want to shoot action then either look for a used N or buy the III when it comes out.  I am looking forward to the dust removal and some other things on that body and I'm not sure if I want to get it as soon as it comes out or in June sometime.  I'm a hobbyist but love my toys :)  I shoot mostly grade school sports but will be doing some H.S. this spring and maybe it will be time to make some money on the H.S. sports :)

For what these bodies cost you really should look for ways to get a return on the investment - ouch!

"Only lenses that do not fit the D series are non L's anyhow I think.  Not sure if they make a L EF-S lens."

Hi armalite

No maybe I am reading you wrong here the only lens that will not fit the D series are the EFS range... To clarify this to avoid confusion: 

The "S" in EF-S stands for "short back focus", which means that the rear element of the lens is closer to the image sensor than on regular 35 m Cameras The proximity of the rear element to the image sensor greatly enhances the possibilities for wide angle and very wide angle lens, enabling them to be made smaller, lighter (containing less glass), faster (larger aperture) and less expensive. Most current Canon EF-S lenses are wide angle. The EFS Macro is poor quality, and recent tests seem to prove this.. However if you own one of the cameras that will fitan EFS lens they offer great value for money and the faster and lighter design are the main selling points, if you cant go to L glass, but bear in mind at a future date if you upgrade to a D series or the 5D you will not be able to use them.. Jim has given an accurate list of the cameras that are able to use this mount.

EF-S lenses, however, can not be used on EF mount cameras and Canon designers have taken steps to ensure it is physically impossible to mount EF-S lenses in this way. This is because the increased proximity of the lens to the sensor means that on full-frame sensor or 35mm film EF cameras the lens itself would obstruct the mirror's movement and cause damage to the lens and/or camera. An additional reason is that the lenses produce a smaller image circle of even illumination (circle of no vignetting).

The 10D and Earlier cameras D30 D60  share the EF-only mount with the full frame EOS camera bodies, despite having a smaller sensor and therefore a smaller mirror.  The mirrors on these cameras are larger then those models outlined by Jim.. And indeed the mirrors on the 2OD etc had to be redesigned in order to accomodate this, moving back in a different way with some increased noise, and less bright viewfinder.. Several people have successfully mounted the 18-55 EF-S kit lens on 10D cameras by modifying the mount on the lens, with successful results. However, attempting this on full frame Canon EF mount cameras would cause the mirror to collide with the rear lens element and potentially destroy the lens and/or camera. So be warned!!  I know that the use of an extension tube may also work, but this would limit the infinity focus.. I would not recommend you attempt the above modification unless you fully understand what to do..

Danny I should have explained what I meant just a  little bit better then I did LOL sounded confusing to me after reading it again LOL.

Okey dokey I thought that must have been the case ... Just wanted to ensure nobody tried to use an EFS lens on the wrong camera..

For whats it worth,  EOS stands for Electro Optical System...but yer all knew that :)

tempting :)

Dont get me wrong, more than happy with the 1DMk ii :)
