Combining a 100,000-pixel RGB metering sensor and DIGIC 4 processor, the Canon EOS-1D Xs new AE system, the EOS iSA (Intelligent Subject Analysis) System, is capable of determining not only brightness levels, but also a subjects face and target color, making possible high-precision exposure control. The newly developed AF system incorporates an AF sensor with a total of 61 autofocus points for improved high-precision subject capture. The sensor includes 21 f/5.6 cross-type sensors, 20 f/4.0 cross-type sensors, and 5 f/2.8 dual cross-type sensors. Equipped with 20 f/4.0 AF points, the new camera offers the same level of precision as the EOS-1D Mark IV at f/2.8. Additionally, working in tandem with the new AE system, the cameras EOS iTR AF (Intelligent Tracking and Recognition Auto Focus) function is capable of tracking a subjects face or target color to maintain focus on a moving subject.
Focal length is just how "zoomed" in it is. Correct, you can not adjust a prime lens.sfedai0 said:Guys, can someone explain focal lengths? Am I correct in that focal length can not be adjusted on prime lens, like my 50mm? What can adjusting focal lengths do on say, my 12-60mm?
Mistle said:Focal length is just how "zoomed" in it is. Correct, you can not adjust a prime lens.
For the 12-60mm, you can adjust it to be anywhere between those lengths. With 12 being zoomed out and 60 zoomed in.
Yeah, but without a decrease in qualitysfedai0 said:Awesome, thanks! So basically cropping your pics.

New 61-Point High Density Reticular AF
The EOS-1D X includes a brand new 61-Point High Density Reticular AF, the most sophisticated DSLR AF system Canon has ever released. The 21 focusing points in the central area are standard precision cross-type and effective with maximum apertures as small as f/5.6, depending on the lens in use. The center five points are also high-precision diagonal cross-type points for maximum apertures as small as f/2.8. All 61 points are sensitive to horizontal contrast with maximum apertures as small as f/5.6 and 20 of the outer focusing points function as cross-type points with maximum apertures as small as f/4.0. Other innovations of the new 61-point High Density Reticular AF include expanded AF coverage area, superior focusing precision and low light sensitivity, and greater low-contrast subject detection capability compared to earlier EOS AF systems. (See image below for AF point configuration)

XMonkey said:When you're at those apertures, those are the amount of cross-type AF points available to use. I think if you're above 5.6 it can use them all? Not sure...
Show me samples god damn it Canon!When asked to for the biggest improvement in the new camera, Westfall stresses that every aspect of the camera has been re-assessed but finally concludes: 'If you had to highlight just one thing, I'd say the sensor. It's a new level for us in terms of image quality.'
'There's a couple of things that we consider when we think about IQ: number one on this sensor is noise. It's clear the noise level is better than in the 1D Mk IV or the 1DS III. The pixel size is larger than in the 1DS III or 5D Mark II (6.95 microns, versus 6.4) and the difference is even more striking compared to the 5.7 micron pixels in the 1D Mark IV. That helps us in terms of light capturing ability and increases the signal to noise ratio. In turn, that does nothing but help the dynamic range of the camera.'
And its this improvement in image quality that Westfall believes will make the 1D X appeal to 1DS as well as 1D users. 'I think the factor that's going to make that a reality is the noise level is better than anything we've seen before. With cleaner images, people are going to feel much more comfortable up-rezing an image. Not many people need a 21MP file to begin with, so they're going to love the IQ of this camera and the quality's good enough that those people who do need those huge files will find the images clean enough to use them.'
It's kind of odd to think the next 5D is probably going to have more megapixels than the 1DX.VNZ said:I'm glad the megapixel race is officially over (in this part of the market at least). Now, bring on 5DmkIII.

Omiee said:well im finally going to buy a nikon 3100, im loving my sony nex but i just really want to be able to use more lenses.
any recommendations?
Damaged said:Not too sure what you mean by recommendations but I have a D3100 and its a great camera, as far as lenses for it go i'm told that the 35mm f1.8 G DX is a good cheap prime lens to start with. I'm still on the kit 18 to 55mm that came with it and a cheap second hand 55 to 200mm I picked up on holiday in Japan
Omiee said:im sorry i meant lens recommendations.
i was thinking about picking these two up.

But it would be amazing if they use the 1D-X's sensor in the 5D3
Even Nikon is moving away from it. D700 will be the last "affordable" high ISO low mp body.BlueTsunami said:This'll probably be the case

?
golem said:Cross type sensors also work at apertures bigger than them
So its:
21 cross at f/5.6
41 cross at f/4
36 cross at f/2.8 + 5 that now work as diagonal cross
I think

Studio use, sir. When the camera is permanently mounted, wired makes more sense.luoapp said:What's the Ethernet for? Doesn't WIFI make more sense?
I am thinking more along the line of tethered shooting. Isn't WIFI so much better? How about tethered to an iPad wirelessly? Like sarcastor said, they probly just want to sell you overpriced WIFI attachment.MultiCore said:Studio use, sir. When the camera is permanently mounted, wired makes more sense.
Didn't I describe a tethered setup? (scratches head, rereads post) *shrug*luoapp said:I am thinking more along the line of tethered shooting. Isn't WIFI so much better? How about tethered to an iPad wirelessly? Like sarcastor said, they probly just want to sell you overpriced WIFI attachment.

Zyzyxxz said:Ok I'll be in Hong Kong in a week or so, I want to buy a new lense while I'm there since I'm only carrying a D90 with a 35 f/1.8.
Need something wider and does anybody have a cheaper recommendation than the 24mm f/2.8? I don't want to go for the 18-55 VRII since it only goes to f/3.5 on the wide end as I will be in somewhat lowlight at some restaurants.
Wider and faster and cheaper than 24mm 2.8? I don't think so brother.Zyzyxxz said:Ok I'll be in Hong Kong in a week or so, I want to buy a new lense while I'm there since I'm only carrying a D90 with a 35 f/1.8.

MuseManMike said:My parents want to purchase a Nikon DS3100 DSLR for $599 this week. I have a small photography background myself (few semesters worth of photography classes), but it's been a long time since I've touched a camera that isn't a point-and-shoot. Your thoughts? Be as technical as you'd like.
I hope this is the appropriate thread for something like this. If not, feel free to link me accordingly.
I'm sure, but I'd like slightly more elaboration/options. What about in comparison to the T2i? I'd be willing to make up the price difference if the value was there for me. I'll be using it as much as they are in the coming months.golem said:Cant go wrong really with entry level DSLRs
Valkyr Junkie said:Didn't have a chance to shoot with it today since I got home late and the weather wasn't great, but the few test shots I snapped seem promising. Thankfully in the hand it feels a lot better balanced then it looks.

Next on my list is a legacy MF lens. From what I've read the 40mm Konica Hexanon isn't very sharp or contrasty until you step it down into ranges where you might as well just use the NEX kit lens. The quality of the 50mm shots look awesome, but I'm not crazy about that focal lens on a crop camera.
Its a phone camera with simulated depth of field. I doubt it can do difficult objects (fur/hair/tree branches) in the foreground correctly.Greyface said:Lytro plenoptic light-field camera pre-orders begin today at $399, devices ship in 2012 (video)
I'll be eagerly awaiting reviews of this.
