boissez: what is sRAW?

update: found it .. small RAW .. very cool but it kind of makes the 1d3 the world's most expensive 2.5 mega pixel raw camera!

Makes sense though since alot of the pro shooters (Eg PJ's) only need small files. Now they have the option of shooting RAW and being able to keep file sizes down (Great for transfering photos over the internet back to the office).

With the Live View Mode you have sort of a MLU button

I dont know about you guys, but I am pretty sure I will upgrade once I do see sample shots of 1600 or even 3200. I have gotten into situations where even at 2.8, iso 800 I am still not getting fast enough shutter speeds. right now with the N I am very uncomfortable shooting at 1600. If a little sharpening is applies, boy do you see the noise.

So far I am very happy with what Canon is going to offer in the new III.

I wonder what this means:

APS-H is the largest sensor that can be imaged in one pass using cutting edge semiconductor manufacturing technology..

(Found on page 9).

They have...it's the "set" button that enables "live preview" which is in effect a MLU with the added bonus of seeing what's about to be shot.

Yes, but only MF and only evaluative metering can be used.

So if they are quoting 2200 shots on a full battery charge, and given people usually get more than the quoted amount, I expect the new line once these start to appear on B&S will be "battery only charged once."

You can use the set button and function just like a mirror lock up, with auto focus and normal metering before you push it. You do not need to look at the live preview at all and can just proceed with the shot when you judge the mirror slap has died out. But the live view adds lots more if you want to use it. The remote location live view type functions are valuable for some sports and photojournalism uses, which is a big reason it made it on to this camera. For me, when doing landscape type photography, direct live view on the large rear screen will add manual focus check and or adjustment any where in the frame of the image, just like a view camera. The 10x magnification, and the provided artificial sharpening of the image, should make for very accurate manual focus, when you have the time to do so. You will also have the ability to accuratly check focus both wide open and at shooting aperature, which for landscape is very important. Focusing an image from a tilted lens is a big application of this. Also, 100% view framing with optional digital "grid lines" for horzontal check are another thing that landscape and all other tripod photography will make big use of. Another whole area for live preview is astrophotography, where it will add a lot to that use. No more special 20dA model needed, because it is standard.

I happen to do both action photography and landscape photography, and also some astrophotography, so I will be buying this one. I also look forward to when the 1dsMK III comes out, where the live preview will have even more value to the typical user of a high resolution camera.

Semiconductor lithography tools for patterning (often called steppers or scanners) have a limited slit width and scan length. These dimensions define the maximum pattern in x and y that can be transferred onto a silicon wafer in one exposure, so they are saying that they CAN do it with this sensor.
The FF sensor has to broken down into sections that they step with different reticles. Kodak wrote a paper about it a long time ago when they made FF sensors, if I remember correctly they broke the die up into about 4 or 5 areas with different but repeating patterns. The scanner loads reticle #1 and exposes the correct places on the wafer for each sensor, then it loads reticle 2 and so on. If you underexpose an image badly and then push the exposure you can often see the seam in the sensor as the dimensions of transistors are not perfectly matched.

Given that any battery can fail at any point in time, one will still need a hot backup battery if not having a full backup body.

* Mark III Digital SLR, a photographer has several options in addition to conventional SLR through-the-lens viewing. If the camera is going to be close at hand, the new Live View shooting mode lets the user focus and compose on the extra-large 3.0-inch LCD screen and magnify the image 5x or 10x, to achieve the optimal focus

I am not a big fan of using an LCD to take pictures but the live view with zoom features sound like a tremendous aid in confirming sharp focus, if you have the time to use manual focus.

I better check that lottery ticket in my wallet.

I think they should have gotten one of the FMer's in N&W to take the eagle shot. Nice shot (I'd LOVE to claim it as my own) but I see better over in N&W almost daily.

Some of the other images look incredible though.

Sort of cheesy, but here's a wallpaper I took from one of the pdf files at Canon Japan. We are going back to Alaska in Aug., and so we have a bunch of Alaska wallpaper photos, and the image on the LCD caught my attention.

Q: Why do they continue to use that old 1980's-style digital readout in the viewfinder and the top LCD panel? I'm not complaining for the sake of complaining, but is there actually a reason for it? Why can't they make nice, smooth edge "Arial" type text in the viewfinder and top LCD? Is there a production reason that I am not aware of?

as far as I know, it's easier to build a low resolution "digital" display than a pixel-by-pixel LCD.

Yes... because the 1980's style LCDs are cheap and reliable. High-res displays such as the one used to view pictures/histograms on the back are comparatively expensive and less reliable.

That would make sense, I guess. I'm only thinking of it from a marketing perspective, and I would think that the polished look of smoother text would add to the overall feeling of quality in the end product. That, plus they should be able to fit more information in the viewfinder, and still have it be more easily readable. Like I said, nothing to complain about - just an observation.
