Does anyone else have a full sensor full of dual-pixel phase-detection capable pixels?

EF mount and the Rebel line are the only innovations you can think of?

How about image stabilization, ultrasonic motors, a relatively inexpensive full-frame digital body, and high-def video in SLRs?

How about eye-controlled focus, and diffractive optics?

How about DPAF?  Etc.

I think AvTvM's definition of innovation means making the exact specific camera he wants...

Which, apparently, is a 300D.

Image stabilization ... no Canon invention.

"The Canon EF 75-300mm f/4-5.6 IS USM (Japan)[255] of 1995 was the first interchangeable lens with built-in image stabilization"

Ultrasonic AF drive .. no Canon invention.

"Canon was the first camera maker to successfully commercialise the USM technology."

Hi-def video in DSLRs .. hardly much of an innovation.

It practically created a whole industry over night.

Those who need it shall buy proper video cams. Should not be forced on regular DSLR buyers.

Show me a full-frame video camera at the cost of the 5DII when it was released.  Forcing it on regular DSLR buyers reduces the cost of the bodies substantially.

And, diffractive optics.

IMHO as canon has declined and ceded a lot of market back from the glory days where they 80%+ dominated every segment, they need to go this way or really start challenging mirrorless. The problem for canon is that they have the same problem Nikon had before they turned around: protecting a market. Canon and to a lesser extent Nikon are making decisions to stop the mirrorless take over instead of embracing it. In many ways, they are the blackberries of the world facing the Android take over. evolve or die.

That's assuming mirrorless is better for everything.  It isn't.  It's better for video, and in some cases for manual focus situations, and that's about it.  It's worse at just about everything else.

For doing actual imagery, the 600+2x or 800+1.4x is probably a superior system - better optics, better coatings, IS.  If you really need a lot of resolving power, telescopes are where it's at.  Mine cost $2,400 used and is 2,800mm and f/10 or 2,000mm and f/7.

Perhaps, although the 1200 is a stop faster than the 600+2x.

True, but as mentioned in the review, it's not all that great optically until f/8.

As for telescopes - I've no doubt you're right (and in this context they'd be the cheaper option), but I've used my 500L for planetary imaging because I don't have the spare money (or inclination) to buy a whole extra piece of kit for that. The results will be nowhere near as good as a dedicated system, but they made me happy :)

I looked at it backwards.  I wanted some serious resolving power, and even the smallest Canon supertele was just way too expensive.  So I bought a much cheaper but far superior telescope instead, and gave up IS, bokeh, and AF for shear optical power.  Saved over $5,000 too.

Firstly let me say that I have no interest in whether or not man landed on the moon. However, the whole did we didn't we debate is rather complex.

No it's not!

A very small group of nutters have the totally insane idea that maybe it was faked, despite an absolutely overwhelming amount of evidence that it wasn't.

Nothing complex about it.

0:22:40 thru 0:26:40  -  shadows that don't line up for infinity isotropic light source (sun).  I'd like to hear a good reason how this photos like this were taken on the moon and not under artificial light.  I've never seen a lens create this kind of anamorphic distortion and the surface does not appear to have any topographical features that would create an apparent shift in shadow directions. see screen shot below.


I'll answer just this one.  The lander is up on legs and next to a slight hill on camera right.  This makes it's shadow appear like it's going a different direction when it's not.  Look carefully at the lander and its legs and you'll see that its shadows are consistent with those in the rest of the image.

By the way, this one and many more were debunked by the Mythbusters.  Go watch the episode.

Sneaker Zoom is quite a bit cheaper

Not if you want to shoot extraterrestrial objects (the moon, other planets, etc.).

Do you get out much?

Got out last night.

Who in the world, ESPECIALLY pros, want to pull the camera away from their face so they can fiddle with a clunky touch screen?

Well, how about pros (or amateurs) who shoot with the 600 EX RT? Or Pros or amateurs who want to change tracking sensitivity or accelerate/decelerate tracking? There are dozens of functions that cannot be adjusted with a camera glued to your face that would be much easier and quicker to accomplish with the swipe of a finger rather than having to work through buttons and joysticks.

People need to open their minds a bit and quit being such Luddites about technology (especially ironic on a forum filled with gearheads). No one has ever suggested that a touch screen would replace the buttons and joysticks, but it is proven technology that would add significant functionality and convenience to enthusiast and pro-level cameras.

A touch screen is great when you aren't shooting stills.  When you are, being able to change numerous things on the fly without removing the camera from your face is crucial to getting the shots.

I wouldn't mind a touch screen as long as tactile controls still exist and are well thought out and implemented

No wifi or touch screen? Bummer. All future canon prosumer cameras should have BOTH wifi and touch screens IMHO.

I never liked Canon's wifi implementation.  I have had great success using an Eye-Fi card when I need that capability.  I dont think that built in wifi would be a deal breaker since it can be added later.

Can you control the camera and use live view over an eyefi card?  I have no interest whatsoever in downloading pictures over WiFi.

Just the 20D and 5D.  The Rebel is for work, which is not fast action.
Hmm I couldn't wait to be rid of those for action work. I mean sure you can get great shots, but it was frustrating that misses were a lot more than when using 1D2n.

I get hit rates of high 90s for moderate action and mid 90s for very fast action.

And, no, that's not good enough.

I am still wishing for a hybrid viewfinder. What I mean is a viewfinder that can be used for video... I guess only few people care.

I do.
