Canon videos showcase 70D's innovative AF system

But doesn't it make the actuel light collecting pixel smaller, causing less DR?

a grandma may beat an experienced video guy using facial recognition assisted dual-pixel cmos AF tracking.

just find your kid on iPad and touch.

Yes tons of people shoot this way using SLRs, but it has nothing to do with ergonomics. It's simply convenient and cost effective to have one camera to do both. It allows you to use high quality lenses and large sensors (=good image quality) for video. That advantage has nothing to do with the fact that it's not an ideal way to hold a camera in that way for a while.

Let me see how you hold an SLR with a 70-200/2.8 one foot in front of your face with one hand and, follow a kid running on the field, and try to use the other hand to tap the "freaking" screen. Or hold it like that for 30 min shooting a stage show.

Geez, is that the best you got? First of all, I assume we're still talking about DSLR video shooting, right? Ever hear of a monopod? LOL. Also, I think I'd tap the screen to acquire initial focus, then just let the focus tracking follow the "kid running on the field."

As you can hopefully see, you're simply offering a desperately absurd description that has no resemblance to how people actually do things in the real world! If I know I'm going to be using a 70-200/2.8 to shoot video, I'll mount it on a monopod, allowing me to comfortably shoot for as long as I want. I use a Bogen/Manfrotto 676B Digi Monopod travel monopod that is very light, compact when collapsed, you hardly know its there. Simple solution! Think, man!

I'm just a normal person, and I felt the movie was bit odd and uncomfortable to watch so I commented. If you feel differently, then that's totally fine.

The focus was on focus. So focus on that please. Besides, how do you know you are normal?

@ SRT3lkt - I think the issue is more with you than with the video. Seriously, you really think that "just everything is off" with the video? LOL. "Everything" is off? From the music, to the timing, to the lighting, to the composition, you claim? And you could "hardly focus"? LOL. Maybe "just everything is off" with you! Just a thought. Yes, maybe you're right...that you "might not be 'normal'." Time to take your meds?

What kind of medication you think I should be taking?
You might be making sensible point by writing so much though...

Exactly, with mirrorless becoming more popular this could really help the M series.

how does that work for you at f/11?

This is a big leap forward, not catch up. Sony and everyone else would love to be able to have something like this in their cameras, particularly the Nex models.

Sony SLT uses a separate phase detect AF sensor via a semi-silvered mirror. This is not much different from a standard DSLR except it allows for continuous focusing at the cost of some light. This technology eliminates the need for a mirror and a separate phase detect sensor allowing cameras to be smaller. Plus it can cover a much wider area.

To Princess Leia Ignorana, Canon has made a pellicle mirror SLR back in the 90s named EOS-1RT, so it's Sony that copied Canon in that regard.

"Like" my post if I have sufficiently 0wn3d the Princess above. TIA

@AlanG

Sony have a dual PDAF system on its A99 model; on-sensor PDAF as well as the PDAF SLT technology. Although I have to admit that this solution seems to be half baked when compared with Canon have managed to make with this.

Sony's translucent technology was an interesting innovation but it got some shortcomings. the most important is that it loses light, no the image sensor nor the AF sensor can ever get 100% of light from the lens.

now we can see clearly that SLT is fundamentally flawed, that the incoming light is always split between the AF unit and the image sensor.

sensor technology is totally another issue. Sony sensors used to be among the best ones, then lagged far behind Canon, then became the industry leader with Exmor parallel readout, but this is like tide and wave, has nothing to do with the basic design.

You already mentioned why Panasonic is streets behind. This AF method doesn't need to "rack" the lens back & forth precisely because it is an on-chip PDAF. Read up a little before you post again.

If you have access to every Canon lens currently in production, why not use them?

actually this is not junk food. fresh dough, fresh mozzarella cheese from cows without hormones, fresh simple veggies, put in wood burning oven for a minute or two and you're done. nothing junk about this type of pizza which is called Artisan Pizza in the US or Neapolitan style.

Dear Zoltan do not insult what you do not know, it is offensive and you make a fool of yourself.

Fallacy. Italian-Americans created what the world considers pizza. Italians were happy with crusts with a bit of sauce and a sprinkle of parmesan.

BTW, tomato sauce is a purely American creation. The tomato was domesticated by Pre-Colombian Mexicans. It did not reach Europe until about 1600.

Yeah excess salt, fat and carbs, are what Americans have been surviving on for years...and who ever sees obese 'merkins...;-)

@ John Koch, the "world" was long eating what they considered and still is considered pizza before American Italians existed. And not every pizza has a tomato sauce so I'm not sure what the Aztecs have to do with this or the US.

I respectfully disagree.
Moreover, if you look at the credits one of the names (& face) surely looks Italian.

-And-

There's no such thing as "too much" extra-virgin olive oil, even better if it's from Tuscany.

Ilarious, very, very ilarious, are you american, for sure.
Seems like the tradional "Pizza napoletana", the only Pizza in the world, and it's a "Margherita"; tomatoes, ONLY italian mozzarella, "fior di latte" or "Mozzarella di bufala campana", and not american "mozzarella", basilico, oil, and ONLY italian "extra vergine di oliva", and not american motor oli...And the border of neapolitan Pizza MUST BE BROAD, NOT SMALL.
Americans......Ahh...And very very very very important, ONLY wood cooker, not electric.
Or you think that the orrific, artificial american pizza is pizza??
Mó gli ammeriggani si mettono pure a pontificare sulla Pizza, pazzesco...Ma magnatevi i vostri squallidi hot dog e non mischiate il sacro col profano...Pizza vuol dire secoli, millenni, di storia!

Don't get too carried away... Pizza is junk processed food.

Zoltan is obviously clueless. FreedomLover, I could not agree more. Antimateria, snobby arrogants like you make Italians look bad, keep your mouth or better your keyboard under control.

Hey, give Antimateria a break. She's right about pizza napoletana. If you haven't eaten it in Italy, it's hard to explain how much better it is there. My first clue that it wasn't the real thing, is that in Italy, you get one pizza per person, and you eat it with a fork and knife.

You are right, photomy, thank you for kindly clarifying.

The increasingly important software is failing, open source firmware would help.

I hope Canon try their best to reduce the weakness before releasing the cameras. there is still time to improve the cameras

That's still a lot better than CDAF on other cameras. The only way to keep a moving model train in focus like that with another DSLR is to use the viewfinder and keep the focus point on the head of the train....but you can't really record through the finder.

FreedomLover is the quintessential nitpicking equipment measurebator. Pray tell what other DSLR or MILC can AF better using the whole image sensor??? Ah, I thought so. BTW, Canon never claimed that this AF method is 100% idiot-proof nor that it is faster than a 1DX tracking AF.
