thx for such informative answers gentlemen :)

rienz.. This is the charger I use

this brings up a question i've had for a while now

i use the eneloops for my flash (the white/blue ones - not the black XX 2500mah)

and a powerex mh-c9000 to recharge them - love it!

of its many features, it permits you to set the recharge rate

the documentation warns against giving the batteries too much juice during recharging (ie, re-charging too fast)

i always set it to 700 (out of 1000)

i'm curious... if you use a re-charger that allows you to set the recharge rate, what rate do you use??

just gonna throw this out there...

based on historical experience (1D3, 1D4.. do those release period experiences apply?) approx when can we expect the 1DX to become generally available?

i understand pre-orders must be fulfilled - but i only just late last month came up with the funds for this

anyway, i know that nobody "knows" -- just asking the general question..

The unexpected firmware that only makes this very good camera even better by adding new features beyond those you purchased it with is not good enough for you people? OMG

^this^

in answer to the "why" f8 is a limiting aperture, i think i found a satisfactory answer on canon's website

it gets into some basic concepts of how those AF sensors work - pretty interesting actually

basically, the wider the aperture, the more precise your focus - alternatively, the smaller the aperture, the less precision possible

basically, they had to make a design decision - do they tolerate softer images, or stick to their guns and ensure higher quality photos?

Where does the term "high precision" come into play? The farther apart the two rows of pixels are, the more finely the system can adjust the focus, and the more accuracy it can apply to determining whether focus is "close" or "dead-on". Slight deviations in where the twin beams are focused, if they are off-center, now can be measured in finer increments. Canon EOS SLRs with high-precision AF sensors simply move the pairs of sensors much farther apart, and accordingly, the AF information can be more finely broken-down and reacted to. So why not simply move all the line sensors farther apart? There's a limit, and that is the widest aperture of the lenses a shooter might use. To adequately cover the entire AF sensor array, every AF sensor requires lenses (or a lens + tele extender combination) that's a certain f/stop or wider in order to assure proper AF operation. Standard-precision AF sensors, positioned relatively closely, can get by with lenses f/5.6 or faster. This is an advantage in some ways, because nearly all AF lenses can be used without limitations.

But high-precision AF sensors have traditionally required lenses with f/2.8 or faster apertures, since each high-precision AF line pair is farther apart, and requires a physically larger "cone of light" coming into the AF system to fully cover the rows of pixels. When a lens slower than f/2.8 is used, those line pairs no longer function, and (usually) the camera reverts to another pair of standard-precision AF sensors. But high-precision AF sensors provide from 2x to 3x the AF accuracy at the sensor of more traditional designs, and that accuracy kicks-in when a wide-aperture lens is mounted. In other words, high-precision becomes available when it's needed most – when lenses with very narrow depth-of-field are mounted and being focused.

very interesting article - you should give it a read - they explain it quite well

before this thread though, i had no idea how AF worked

hahahaha! yep!

now that i've read around (this isn't the only thread on this topic) i've seen other ppl have also made that observation

i registered to this site just to post that!lol

i just got a 7D and i'm really liking it - and with the 5d3 release possibly around the corner.. its just kindof an exciting time :)

good looking camera, whatever this thing is - maybe "someday" i'll be able to afford it!!

jumping in wayyyy at the end of this thread

no, i haven't read all nine pages!lol

but... referring to the new pics out of africa (aperture academy - possible new 5d3) - seems to me there are TWO cameras in those pictures

this one (same basic layout as 5d2/7D) and this one (totally new arrangement)

has there been any speculation on what the second camera is??
