200 lines of resolution per mm.
So 200 lignes X 24mm high X 200 lines X 36 mm witdh
gives you a resolution of 34 560 000 pixels or about 34 meg.
But it was with a black and white Panatomic-X of only 32 ASA from our friend at Kodak.

Looks to be a prosumer body; hence probably more a Canon 5D MkII competitor (or whatever they will call it) then a Canon 1Ds MkIII competitor. Most definitely not positioned against the 1D MKIII; since thats a sports/action camera and not full-frame(1.3 crop). So hopefully this camera will cost closer to ~$3k(near the 5D) then ~$8k(1Ds MkIII).]]>Feb 1st 2008 3:30PMhttp://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/http://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/>Does a camera such as this exceed 35MM film cameras in resolution? 25MP is a hell of a lot pixels. It looks awesome in size and style.

These ultra-high megapixel cameras are really for photographers that want to make high-quality large prints. An A4 print at 300dpi is only around 8.3 megapixels, even a bit of cropping factored in a lower megapixel camera is more then adequate (such as the ultra-fast full-frame Nikon D3), however if you move to A3-sized print at 300dpi is around 17.5 megapixels, and a A2 at 300dpi is closer to 34.7 megapixels. That's where high-megapixel cameras really show there strength, and Canon has the 1Ds MkIII currently in that market (at 21 megapixels), and there are medium format digital cameras that offer even more performance at a higher price. Sony may have a cheaper alternative to the 1Ds with this camera (we'll see when they announce the price). ]]>Feb 1st 2008 3:46PMhttp://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/http://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/More pixels have to do about size, not quality. And, currently a 35mm negative can be scanned at 4K or so which is 4000+ pixels by 3000+ pixels which is around 12 million+ pixels.

how many negatives can you get in that sentence?]]>Feb 1st 2008 4:59PMhttp://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/http://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/
first off- Its not hands on if you dont actually get to touch it, or even see it turned on.
2- They just havent released the model name. Its most likely a900, but its definately NOT "flagship model"
3- its not fully ready to ship yet, so thats why it doesnt have a model name or full specs yet.

Sony Alpha DSLRA350 --> $799.99
Sony Alpha DSLRA350K + 18-70mm f/3.5-5.6 --> 899.99$

If the Sony 25MP full-frame DSLR is 3.000$, there will be a huge price gap between this one and the a350. I think It will be cheaper than expected or that sony will release a a800 or even a a500.]]>Feb 1st 2008 5:05PMhttp://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/http://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/Feb 1st 2008 5:09PMhttp://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/http://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/> 6 Megapixels equals standard 35mm film in terms of resolution

a) I don't know what you mean by "standard 35mm film"

b) Even the grainiest 35mm film has higher resolution than that.

It is hard to equate film resolution with digital resolution because film consists of three color layers (like a Foveon sensor) that each contain a number of light-sensitive crystals, and that number can vary. The crystals also overlap, because it's an analog medium - they're not staggered exactly equally like in a camera sensor.

But on each layer of film, there are approximately 3000 crystals across and 2000 down in the coarsest of 35mm films. That's 6 million crystals *per layer*, or 18 million total. And each one of those crystals carries both color and picture detail, so you don't just throw the number from two of the layers out - you have to count them.

Higher grades of film can have as many as 6000 crystals across and 4000 down, and because we're working geometrically, that actually works out to 72 million crystals.

Now, 72 million crystals, as I said, doesn't automatically equate to 72 megapixels. Because some of the crystals overlap, are slightly different sizes and are spaced somewhat unevenly, you're not really getting 72 megapixels worth of picture detail. However, you are getting better color separation and detail than a 72mp Bayer sensor would give you. So it's probably a wash overall.

Also, this is the resolution of the *film*. There are other factors involved in picture detail, like the resolution capability of the lens, and especially your method of printing and the quality of media you're using. But that's just as true of digital cameras and printing. (If you take a 25mp image and print it at 4x6, you're gonna end up with about a 1mp photo.)

I'd say digital cameras still have a ways to go before they match the detail of film. Though that doesn't mean I favor film - I shoot entirely digital these days. It's much easier to get "good" results with digital than it is with film... but it is *possible* to get better results with film than it is with digital.

You forgot the A700 which has been out for awhile. Which is around $1300. Canon has a similar gap between the 40D and the 5D.]]>Feb 1st 2008 5:22PMhttp://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/http://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/

Weren't Sony's previous cameras equiped with APS size sensors?

Most traditional SLR lenses are designed to fit "full-frame" sensors, since "full-frame" refers to the size of 35mm film. However, more recently cheaper APS-C-specific lenses such as Nikon's "DX"-lens and Canon's EFS lens aren't designed for full-frame sensors. Sony's equivalent to the "DX"/"EFS", is the "DT" lenses will not work with a full-frame sensor. The professional "G" lenses will however work fine, as well as the majority of the large past category of Konica-Minolta lenses as well as the superb Carl Zeiss lenses.

In addition to that, Sony and Carl Zeiss plan on releasing eight new pro lenses along with this camera, ranging from wide-lenses to massive telephotos. ]]>Feb 1st 2008 6:14PMhttp://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/http://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/Feb 1st 2008 6:39PMhttp://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/http://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/Feb 1st 2008 7:20PMhttp://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/http://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/Feb 1st 2008 7:25PMhttp://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/http://www.engadget.com/2008/02/01/sony-25mp-full-frame-dslr-hands-on/
Companies like Intel and Sony tends to have a price advantage over companies like Kodak when it comes to producing CMOS sensors over CCD sensors because CMOS manufacturing is very similar to semi-conductor manufacturing. Therefore lowering the cost of manufacturing these sensors. CMOS also has the advantage of better speed when comparing the its CCD counterparts but suffers when compared to light sensitivities.

In a recent CNet New.com article published, they interviewed Kodak, Sony and one or two medium-format camera producers to obtain their opinion on the matter. Really interesting read too...
