    I'm thinking this AF is going to be a watered downed version of the new 1D Mark IV imminent in the not so far future. Noticed 7D AF as no assist points. Thinking Mark IV 18MP this AF with Assist points.
    Think I'll just keep my 1D Mark III until the IV appears in early 2010

    Noticed no one has posted this link yet...I wonder why?ne_nau.gifscratch

    Straight from Canon's Website...:

    http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=139&modelid=19356#ModelTechSpecsAct

    Didn't see mention of processor in these specs? Did you?

    Dual Digic 4 processors--curiously not mentioned in the specs tab, but it's the first entry in the features tab.

    Goodoh, R! Yes, that's what was being said everywhere else. Curious it didn't show in the specs on Canon's site, yes.

    Man, that's a power of processing, eh?! Must be for the video, do you think?

    I will buy the next upgrade which doesn't have video. Why pay for that baggage I will never use, in $ and camera resources. I'd much rather get a better still image - higher sensitivity, lower noise, higher resolution, better dynamic range, better AF, AE, and so on. That's where I want to put my $

    Does Leica produce these +video monstrosities?

    Best.

    Dunno. If it's like the 1D series, the primary use would be for supporting high speed burst shooting with capture to two cards simultaneously if so desired.

    Does it support AF Micro Adjustment? One would think so, but I don't see it in the specs anywhere and the manual is not avialble for download yet.

    Interesting question. The 5D II does not have it in it's specs online either, a good sign?

    With the amount of processing power on board, the 7D should be able to figure this out for itself - or is micro adjustment more a question of user preference?

    Conceptually, the AF Microadjustment minimizes the difference in the lengths of the light path to the focusing aperatus and the sensor aperatus - remembering that the light takes a path seperate from that to the sensor during the focusing operation. It involves taking images at various AF MA points and reviewing the results to determine at what AF MA point is critical focus most closely attained.

    I can see, from a conceptual POV, that the camera should be able to do this given a standardized focusing target. This would probably be something that, in this case, Canon would release/sell - and for way toooo much $$$ :D. Conceptually, you point the camera/lens combination at the target, press the magic sequence of buttons and menu selections, press the shutter button and the camera takes two looks at the target. The first look would be during the focus operation and the second would be an analysis of the resulting RAW data. Then the processors would compare the two images, flip a couple switches, make some adjustments, and alert the user to do it again for confirmation of correct adjustment. The rub would be in the first look - with what would the camera look at the target during the first look to generate/save the data needed for the third step - the analysis. But, that would still be pretty cool.

    The hands-on preview at dpreview lists AF microadjustment under custom function III-5:

    Dunno, too. But the continuous-burst specs are not too different to the 40D to need dual processors, one might think???

    You need to look at the image size as well as the frame rate because it takes more power to process larger images. I believe the 7D and 50D use the same chip, but the 7D has two of them. 18Mpixel * 8 fps = 144Mpixels/second on the 7D, 15Mpixel * 6 fps on the 50D is 90Mpixels/second. They're getting 160% of the 50D's performance using two chips, which suggests the bottleneck is probably either in the memory bus or perhaps the mechanical mirror/shutter bits.

    The 40D is the same frame rate as the 50D, but has only 2/3 as many pixels, and uses an older generation chip I believe.

    but not the first specs on dpreview and canon site ... and thats what we curently have for the 7d as well

    40D with 10 megapixels X 6.5 fps = 65 megapixels/second
    7D with 18 megapixels X 8 fps = 144 megapixels/second

    So more than double the processing demand vs 40D, though the same isn't as true of the 50D: 15 X 6.5 = 97.5 megapixels/sec

    The 7D has actually quite a bit more throughput than either mark III, both of which do around 100 megapixels/s

    This camera sounds like every bird photographer's wildest dream come true, weather sealed, high frame rate, high pixel count APS-C camera with seemingly pro autofocus (with micro adjust).

    I really wonder if availability will be an issue this time. It seemed as if getting a 5DMII was difficult for over 6 months after introduction, driving many to make alternate choices.

    Has there been any indication of availability and production rates?

    Anything more than the 5DMII?

    Did the success of the 5D surprise them?

    My guess is you can count on serious availability problems for many months after shipping begins. It might not be as bad as the 5DMII whose availability problems I believe were exacerbated by problems with their battery vendor. But there is clearly going to be a huge demand for this camera.

    PS: Thank goodness it uses the same battery as the 5DMII. thumb.gif

    Alright, you two, just rub it in for those of us who have to figure out where the $ are coming from before we can start to justify it ... ::nono:):

    I'm imagining the conversation now..... "But honey, you don't REALLY want me having to carry that heavy, cumbersome STE2 around with me every time I shoot, now do you? I mean it's great when you can come on a shoot with me to act as bag man, but just think how much less HELP I'll need if I don't have to have all that HEAVY EXTRA LIGHTING EQUIPMENT since the 7D has it all built in. No question about it. I really NEED to add a 2nd body to cut down on transmitter weight."

    Oh yeah. I can seriously see THAT working rolleyes1.gif

    (note to those who may be wondering: yes, I am kidding. I have 100% spousal support in endeavours photographic and, in fact, it's me who keeps the books so I know exactly how much we can and can't justify spending! Which is why I have to wait on this one for a little while, but I am already saving.... :D)

    The rating is slightly faster, but, as I understand it, that's due to a change in the way they measured it. :)

    In any event, they both round to 6.
