The only ones who don't seem to know the 1.3 format is as good as
dead are Canon!
Why not? Take the 24─70/2.8 lens. On a 1.3x format (which is actually more like 1.25x), it becomes ca. 30─87.5 equiv. FOV. Still VERY nice for general photojournalism, and without the edge issues. Take the 17─40/4 or 16─35/2.8. They make for (note the word 'for') very nice 21─50/4 and 20─44/2.8 respectively. They are still wide angle without the edge issues. A note for Canon:
Put the 135 format sensor into a future EOS 1Dn. Make it 16 megapixel @8 fps, or a slightly cropped mode (akin to the Sony CMOS sensor in the Nikon D2x), to 10-12 mpix, and that @8 fps (or even more). You'll still have a winner. And put that future 12 megapixel (@5 fps) 1.3x crop sensor into a EOS 3 class of body. Great for PJ, wedding, product, sports, etc., without the premium.
They 'might' be able to get 12MP in a 1.6 sensor and still get very
good high ISO, but that is all difficult, expensive, cutting edge
technology.
Just as it was unthinkable to put over 10 megapixels in an APS-c sized sensor. Voila, enter the Nikon D2x. "Cutting edge," indeed. For year 2005. In year 2006 it will be on the shelves, and in 2007, it will be yesterday's news. Canon (with their 20D sensor) already prove that it is possible to make a sensor with photosites the size of the ones in Olympus E-1 sensor (and even smaller─interline vs. full frame transfers), and much smoother, with more dynamic range. Unthinkable just yesterday.
My guess is that their game plan is to gradually migrate the larger
sensor down the chain.
Forget it. Too expensive if 1.6x provides for enough image quality, and will always be much cheaper than 135 format. Look at it this way:
On a circular wafer, you can etch some 6─8 135 format sensors. In the same area, you can fit two times as much APS-c sized sensors, plus you get more use of the periphery, so imagine you can stack over 20 APS-c sensors on the same wafer. Now, let's say there are 6 flaws on the wafer. The yield of 135 format sensors will be anything between 25% (2 sensors) and 87% (7 sensors). Much nearer the first figure, anyway, since there are many wafers, and flaws are not usually concentrated. With those 20 APS-c sized sensors, you can get anything between 70% (14 sensors) and 95% (19 sensors). With 1.25x sensors, I believe they could fit some 12 sensors (50% yield, 6 sensors). So, assuming that:
─ we take the first figures;
─ the cost of making sensors is the same for small and large ones;
─ the cost of processing a wafer is fixed at $4,000.
We get:
─ 14 APS-c sized sensors, $286 each, or:
─ 6 1.25x crop sensors, $667 each,
─ 2 135 format sensors, $2,000 each.
Migrate down the chain indeed. And there's no point in making just slightly larger sensors. You'd get incompatibility for future bodies. Want wide angle? Much easier to make one lens fit all sensors (same size), than many sensors for backwards compatibility with older lenses.
Most photographers, anyway, have already bit the bullet, and purchased those EF-S lenses. There is no more legacy in keeping those older lenses in your pouch. You just have alternatives now.
Look for a camera with the same number of pixels as the D2x but
much better high ISO in around the fall or spring.
Very true.
What makes this relatively easy to do is the large sensor size.
Relatively easy, but absolutely MUCH more expensive. Especially to the end user, who has already invested in EF-S lenses, and now learns that his new Canon 25D, with 1.4x crop sensor, does not support the EF-S mount, and forcing it causes the mirror to shatter on impact with the rear element on the lens.
All the time they have this, they have a built-in advantage over
the Nikon 1.5, and Nikon have it all to do with all the difficult
engineering to just keep up.
Keep up? Their 12 megapixel D2x is ENOUGH for MOST uses. For those that it is not enough for, the 16 megapixel EOS 1Ds2 is probably ALSO NOT enough. Even the 25 megapixel MF backs might not be enough. We're talking 4x5" or 8x10" film here.
What do you need those 16 megapixels for anyway? What do you need that 15% greater resolution for? Is it worth the $3,000 (66%) more? I don't think so.
