Hi Roy,

Thanks for the link. The rumoured specification list looks to have settled down now. I'd love to be a fly on the wall at Canon's press office just to know whether these leaks were deliberately done in order to create a feeding frenzy of speculation and rumour.

By the way, while the Bob Atkins site appears genuine enough users may want to think twice about signing up with them. The McAee SiteAdvisor report details why.

Another site which has detailed information/rumour is the Northlight Images EOS 40D page. It features two recent specification lists and a few enlargements of the photographs I linked to in an earlier post.

Bob.

I just got the link from the EOS forum site http://www.eos-forums.com/ and posted it here, but thanks for the warning.

Not a problem. Back on topic:

The suggested 12MB raw files below, also point to 14bit image processing

This is getting better and better. If only it's true! And if it is true then maybe the Nikon D300 will have 16 bit image processing. Oh dear, I'm going to have to go and have a sit down and a really strong cup of tea. :)

Bob.

When they (Canon or whoever) goto 14bit even 16bit capture they clearly need to increase their s/n-ration by a factor of 4 to 16 times!
Would be interesting to see how they manage...

Absolutely. At the risk of descending even further into fantasy land I have read that Canon have improved the efficiency of their sensors. I can't provide a link but from memory I think the improvement was largely down to better micro-lens fabrication. It would be lovely to think that thermal noise has reduced and efficiency has increased as well but maybe there is less room for improvement here. Are there any experts in this field who would like to comment?

Development of sensor technology clearly hasn't plateaued yet as the KODAK Image Sensor Technology Redefines Digital Image Capture press release shows. Interesting technique as it seems to use the same trick that broadcast television uses in taking advantage of the fact that the eye has more monochrome than colour sensors.

Even if the next crop of Canon and Sony/Nikon sensors and processors don't match Kodak's claims any improvements would argue for a move from 12 bit processing.

Bob.

P.S. Canon have an interesting presentation about image sensors here. I imagine similar information about the other manufacturers is also out there of you search for it.

Well, may I at least remark that 3CCD designs are another way to dramatically improve noise, as proven with camcorders?
But I'm absolutely no expert in this field :roll:

Returning to the subject of sensor efficiency, yep, it is possible to improve the efficiency with better microlenses and smaller gaps between the photosites. Canon did this when moving from 6 to 8 mpixels with the 300D to 350D, so despite the higher resolution, there was no compromise in sensivity.

I think they're running out of real estate now though, but that enormous R&D budget should still hopefully produce something nice!

Hi folks,

The specification list is still rumour but it looks like the 40D is imminent. The Northlight Images EOS 40D page has a photo (linked to below) of an invoice purportedly from a large US retailer for a 40D.

Now that could be a fake but if you check out the UPC code (near the top left) you get the following result:

Description...........Canon EOS 40D D-SLR W
Size/Weight..........3.74 LB
Manufacturer........CANON INC/TOKYO VIDEO DIVISION (0013803) more items
Issuer Country.......United States
Last Modified.........Tue, 07 Aug 2007 21:12:04 UTC
Pending Updates....2

You can see the original UPC database record at http://www.upcdatabase.com/item.asp?upc=013803086607.

These UPC records may be easy to create/fake as, from the host site, "this free service is run as a hobby". Decide for yourselves! :)

Bob.

Thanks Roy. The speculation is that this price included an EF 28-135mm f3.5-f/5.6 IS USM but I find that hard to believe because the price seems too low and 28-135mm is hardly an all purpose lens on an APS-C sensor. However it might be for the body plus the speculated new EF-S 18-55 f3,5-5,6 IS kit lens.

I wonder how many times I have used the words "speculate" or "rumour" in this thread? Far too many at a guess. Hopefully only a couple of weeks before we know where the truth lies (or so it's rumoured) :!:

Bob.

Some proposed specification lists for the 40D out on the net show the LCD as having a diagonal of 2.5" whilst others list a 3" diagonal.

If the leaked pictures are good then, working on the assumption that the 40D and 30D camera bodies have the same width, I can state, having done a bit of measuring and a couple of sums, that the LCD on the 40D has a 3" diagonal. Whether the camera incorporates "Live View" is anyone's guess!

Bob.

It would be nice for the 40D to come out on September 26, Here's what I mean

Thanks for the link. The picture, however, is a fake as is admitted in the text. Maybe they are right about the date - who knows?

It seems pretty certain Canon is announcing something around August 20th/21st but it doesn't have to be the 40D. Maybe they've commissioned themselves a バースデー・ケーキ(birthday cake). :lol:
