FYI - Bob Atkins preview of 40D (he will update soon)

Bob Atkins has a preview of the 40D on his web site here:

http://www.bobatkins.c​om …non_eos_40D_rev​iew_1.html

He covers several aspects of the camera's features and glosses over the performance, but he promises a more in-depth review by this weekend. Should be good!

Great, thanks for sharing!

Looks like a pretty good upgrade over the 30D. I will be curious to see how the AF compares.

That is the question as far as I'm concerned. All the other features are nice, but the AF is the one I'm most interested in.

I have just read the review and it seems that he has this to say about the 40D

Look at that, he seems to think that the camera is a more than a minor upgrade over the 30D. that's going to cause an issue with some people.

It's definitely more than a minor upgrade with regard to lots of features other than basic image quality, resolution and noise.

This is the problem for most people. We've got used to seeing continual improvements in resolution and/or noise.

The D60 had twice the pixel count of the D30 as well as slightly less noise; a very worthwhile upgrade.

The 10D offered no increase in resolution but at least a worthwhile improvement in noise at ISO 400 and above.

The 20D also offered even cleaner images at high ISO plus a marginal increase in resolution.

The 30D offered no increase in resolution or noise improvement.

The 40D also seems to offer very little improvement in noise or resolution as far as I can tell from the comparisons I've seen so far. The test charts should show the very marginal increase in lp/mm of 10mp as opposed to the 8mp of the 30D. I believe also there might be about 1/2 a stop of extra dynamic range at ISO 100, possibly due to the 14 bit Digic III processing. But that's about it.

Of course, features such as a faster frame rate, ISO bracketing and faster, more accurate focussing are worth something.

Not sure why it should, it is more than a minor upgrade

I don't know much about test charts, but owning both the 30 and 40D, I think there is a difference in IQ.

Resolution and Noise are not everything. If that is all that ever changed on cameras do you think we would keep buying? Surely not which is why you briefly mentioned a couple of the other features the 40D offers. Noise in cameras is so good now that it can't possibly get better by "leaps and bounds". Incremental increases are all you are likely to get now. And if they can still improve noise WHILE increasing resolution on the same size sensor that is nothing but a bonus.

nice review..

i like this point hahaha... never thought of that

"Finally, for pixel peepers and focus checkers, Live View will enable you to pretty quickly tell if a lens is front or back focusing without having to take a shot!"

And I would tend to agree.

there are a number of poeple out there in this forum that seem to think that the 40s isn't a major upgrade over the 30d. the only thread that I can think of right now is the one in the rumours section, called "The 40D - is it the ultimate shaft of an 18 month wait?"

It's like people expect something ground breaking each time a new camera is released.

cool, I will get one right now, hmm wait already got one

I only expect it when I buy a new camera. In the days of film, I didn't buy a new camera every time a manufacturer made a minor improvement to focussing speed, frame rate, whatever.

For me, the improvements are not sufficient, but that's probably because I already own a 20D and 5D. The 40D cannot replace my 5D. Despite another thread on this forum implying that it can, I don't believe it. My 20D is a secondary camera which I generally use when I want the longest telephoto reach. The 40D is 2 models ahead of the 20D, but comparisons I've seen on the net show very little difference in image quality between these two cameras.

Absolutely! I'd keep buying, but I'd add one more factor. Dynamic range.

Resolution, noise and dynamic range are everything. Keep increasing those factors and I shall not be able to resist buying.

If Canon had given us a 12mp 40D with an ISO 6400 as noise free as a 20D or 30D's ISO 3200, I'd have had no complaints and no hesitation in buying the camera.

Such a camera would be feasible with Kodak's new sensor which employs panchromatic pixels to increase sensitivity and new algorithms to interpolate accurate color from the fewer pixels that employ the light-blocking color filters of the bayer type CFA.

well I have upgraded from the 10D to the 40D, which is a big upgrade. I didn't see going from the 10D to the 20D as a big step, and the same as the 30D. instant turn on was nice and bigger buffer but that was about it.

there is enough updates to this model line to make me upgrade. Would I upgrade to the 50D when it comes out in 18 months, more than likely not. I had the 10D for 4 years. I might do the same with this camera.
