Canon 50D/5DII White Paper Published

http://www.usa.canon.c​om …205D%20Mark%20I​I%20WP.pdf

I guess we can now settle the question: "WTH was Canon Thinking...?"

Excellent... I'm downloaded it and reading it now

On page 21 Canon says the following

I know there was some speculation on if the 5D MKII sensor was the same one use in the 1DsMKIII. It looks like we now know that yes, it is, and it was improved upon. They are essentially calling the 1Ds MKIII 21MP sensor a 1st Generation design, and the 5D MKII sensor a 2nd Generation design with better high ISO output.

Another interesting comment on page 31

Up until now many people have stated that the AF function is offloaded on a dedicated AF processor (in discussion with the XXXD, XXD and 5D cameras). However Canon mentions that AF is improved due to the new Digic 4 chip. That would imply that the Digic chip has some level of involvement in the AF capabilities of the camera, which is contrary to the statement that AF processing is done by a dedicated chip. Therefore, even though the 50D and 5D MKII have the same AF system as their previous camera, the mere prescense of a faster Digic chip would logically give them faster AF capabilities over their predecessors, even though the systems are the same.

Another point, on page 35 Canon says 50D shutter is rated for 100,000 actuations and the 5D MKII is rated for 150,000 actuations. The 5D MKII shutter has been completely redesigned and uses a two motor system (one to cock the shutter, and one to move the mirror). I suspect that this new shutter will make it's way into the XXD lineup in the release of the 60D (just speculation on my part)

anyone else reading this?

I've been playing along and have referenced this in other threads...

Nice job of devining the pertinant points.

well I was beginning to think I was the only nerd that jumped on the white paper when it was released.

Someone else referred to it as "Marketing Speak" and I guess to some extent it is (I don't think I'm quite that jaundiced...) but it's interesting to get a little bit of info based in "Here's what we were thinking when we did this..."

Knowing every little detail about all the bells and whistles isn't the be all and end all for me. I guess in that regard, I'm only a Junior Assistant Gearhead.

"Marketing Speak"

:sneeze:

it's both their technical writing/spec mixed with marketing speak (having now read it). But yeah, it's a canon ad for sure....

Tell me about it - Page 57 " Essentially, we'll do and say anything to get you to buy our cameras"

....sad but true, so, so true.




I still can't wait to get my 5D!

but read the 24L II bit and tell me that's not advertising/marketing writing it... Made my 24L scared just reading it....

I'm in no way disagreeing with you... The production value of the pdf alone says "we want this to be as fishworthy a hook as possible."

I'm suprised they don't toss out something like this say one week before a new body is released instead of a week or two after.
