I wonder if the number of posts here compared to the 5DII thread indicate anything about sales?

Thanks. That's very important for me.

I have the opposite experience on my 40D and have reverted to using the center point only and recomposing. Outer focus point proved too unreliable.

The 40D is the first EOS body I've owned that the outer AF points were both accurate and reliable in low light. Most of the others were excellent in good light but I had to switch to center for low light. If only the 40D had ECF instead of that awkward joystick thingie...

Me too. In low light for me (1600, 1/125, f1.4) the outer points are not nearly up to the mark of the center point.

Of course they aren't. DPR:

"The EOS 40D has the same nine focus points we first saw introduced on the EOS 20D however now all points are cross-type (meaning they are sensitive to both horizontal and vertical detail) with lenses of F5.6 or faster. Additionally the center point is now twice as sensitive as any other point with lenses of F2.8 or faster and has cross-type sensors set at forty-five degrees."

Focusing speed and accuracy also depend on lens used, user knowledge of AF, camera and lens callibrated to each other among other things. Fact is, my camera and lenses are all sent in to be callibrated together and I'm getting good results in low light even when using focusing points other than the center point. and I'm talking situations like (1600, 1/30, 1.8) so I know that the 40d focuses better than the 20d based on my user experience. Now, I don't doubt that there are others who are not getting good results. But, those inaccuracies can be attributed to a variety of factors as listed above.

Are you suggesting this is what it takes to get good performance out of D40/D50 autofocus?

If you're shooting something at 1/30, then that tells me it's not moving and that's probably not as demanding of an AF system as it is to shoot moving objects. I shoot live music and 1/125 is a minimum shutter I need because people are jumping around.

At the other end of the spectrum, I shoot horse polo. Anything other than the center AF point is not worth bothering with.

I understand how cross point AF works and what it utilizes, and I use decent lenses (35/1.4, 85/1.8, 135/2 for music and 70-200/2.8 IS, 300/2.8 and 4, 400/2.8). Unfortunately those last three primes are rentals and I can't send them in for calibration to the body but in tests, they are spot on.

I shoot live music and live dance too, so I know what you're talking about. And I'm not discounting your experience. What I am saying is that I have no problems on my end. What I'm also saying is there are a variety of factors that determine whether you're getting focused pictures consistently...with the other AF points.

And don't assume I'm not shooting inanimate non-moving objects because I listed 1/30th. That's kind of reductive, don't you think?

If I may ask, what are you shooting with that slow of a shutter speed?

Even when shooting live shows, when musicians move or make a dramatic move, there will be a peak to the move. You can catch those peaks with slower shutter speeds than you normally would need to freeze movement. And, I should add, not all live performance is movement. There is are some moments when you can get the pic with slower shutter speeds. Think of a singer who hits and sustains one note. They don't move much.

I am amazed sometimes that folks always want to freeze action. Sometimes the great shot is the dramatic motion shot. Other times (sports, for example) you want the moment, frozen in time. It depends a lot on the situation.

Artistic considerations aside, is that really an example of pushing an camera's autofocus ability? I don't mean to be argumentative.

Before I went out with my rental boat to photograph Gulls, I wanted to test the AF on dry land. In the one-shot mode, I put the focus on my 300 / 2.8 IS on infinity and i focused on the gravel three feet away and pressed down. I repeated the process with different motives closely adjacent and the AF sat there with surprising speed every time. Amazingly fast I must add.
I tested the camera with 70-200/2,8 and set the AI Servo while I quickly panned down from the beach 200 feet away on the other side of the water to the surface of the water a few metres in front of me. The focus tracked fine all the time.

When I took up my EOS 1 D Mark III and did the same thing the result was less convincing, I have experienced Mark III-s as fast, but EOS 50 D was clearly faster. I repeated the manoeuvre a dozen times with two cameras.

När det i alla fall gäller stillastående motiv är min bedömning att EOS 50D har världens troligen hittills snabbaste autofokus.
When the motive is still its my assessment that the EOS 50D has probably the world's fastest AF.

The next question was how the camera would work out in the field. To photograph flying birds belongs to the most difficult and most challenging you can expose a camera for in terms of AF.

The new EOS 50D with EF 300 / 2.8 IS and EF 70-200/2, 8 IS with and without 1.4 TC managed for the most part to follow the Gulls which flew after the boat or who flew at me when we anchored. If i aimed correct and gave the camera few tens of a seconds to react i always got sharp images. When it was not sharp, it was I who had missed having the bird in the centre. I used AI SERVO AF with only the central focus point active.

To further test the AI Servo i tried to shoot with all AF points activated. I also stopped down a bit to further increase the DOF. To my surprise, the new EOS 50D with 70-200/2,8 and 300/2.8 worked quite well following birds even with all the AF-points activated. I do not think it works always, but this was clearly better than in any previous camera, I tried.

Canon's new EOS 50D bridges the gap between the novice and the seasoned pro with a perfect combination of high-speed and quality. It features an APS-C sized 15.1-megapixel CMOS sensor for tremendous images, new DIGIC 4 Image Processor for fine detail and superior color reproduction, and improved ISO capabilities up to 12800 for uncompromised shooting even in the dimmest situations. It features a refined 3.0-inch Clear View LCD (920,000 dots) monitor, supercharged Live View Function with Face Detection Live mode, plus a number of new automatic Image Correction settings and HDMI output for viewing images on an HDTV. Pick up the EOS 50D and you'll experience true digital inspiration!

Exceptional Quality Images.
The EOS 50D features a newly-designed 15.1-megapixel APS-C sized CMOS sensor which is capable of recording up to 4752 x 3168 pixels with full 14-bit A/D conversion for extremely fine tonal gradation. Ready to capture images in an instant, the sensor is designed to work with Canon's EF and EF-S lenses with a conversion factor of 1.6x. It's capable of recording at sensitivities previously too noisy for shooting in low light or subjects in motion. With a maximum ISO rating of 12800 combined with a 4-level High ISO speed noise reduction function, images that would have been impossible without the use of a strobe or flash become simple to record.

State of the Art Image Processing.
The EOS 50D operates with such effortless speed that operation is nothing short of intuitive. With instant start-up times, speedy autofocus and minimal shutter lag, the EOS 50D is one of the fastest cameras available today. It can shoot up to 6.3 fps, in bursts of up to 90 JPEGs (using an UDMA CF card), 60 JPEGs (using a CF card) consecutively or 16 RAW files, so you'll never, ever miss a shot.
DIGIC 4 Image Processor
This next generation DIGIC 4 Image Processor offers finer details and even more natural color reproduction, compared with the previous DIGIC III Image Processor. Since Canon's DIGIC 4 chips use advanced signal processing technologies, they provide even faster operations, including write times to UDMA cards. It also enables Face Detection Live mode to detect and focus up to 35 face(s) to capture the best possible shot. Further, DIGIC 4 offers the improved Auto Lighting Optimizer that corrects brightness and contrast automatically, and Peripheral Illumination Correction for up to 40 EF lenses. DIGIC always maximizes performance between the capturing and recording stages of digital photography.

Huge, High Resolution Screen.
The EOS 50D features a bright, high resolution, 3.0-inch Clear View LCD monitor with 920,000 (dots/VGA) pixels and a broad viewing angle of 160° horizontally and vertically. It offers a brighter and more detailed display than the EOS 40D, includes a new smudge-resistant coating, and is perfect for accessing camera settings like ISO, Metering modes AF Point selection and flash options. Plus, it's superb for reviewing, editing and deleting photos or composing new images in Live View Function.

Live View Function Feature For Almost Any Application.
The EOS 50D features Canon's most advanced Live View shooting thanks to the number of focusing modes available including Quick mode, Live mode and Face Detection Live mode. You can zoom in and navigate the composition 5x or 10x normal size, enabling critical focus. There's even 2 overlay grid options, perfect for lining up vertical and horizontal lines. In the studio, the camera can be controlled remotely with Live View Function when the camera is connected to a computer through a USB cable, or wirelessly if the optional Wireless File Transmitter WFT-E3A is used.

Incredible AutoFocus.
The EOS 50D has a high-precision 9-point wide area AF that uses cross-type points at f-stops of f/5.6 or faster, enabling the camera to focus faster, more accurately, and in difficult lighting situations. AF sensitivity is a stunning EV-0.5 to EV18. Adding to this AF performance, the EOS 50D incorporates a diagonally mounted cross-type sensor that is sensitive to both vertical and horizontal lines at f/2.8, perfect for enhanced operation in dim light. The EOS 50D has a number of focus modes, including One-Shot AF, AI Focus AF and AI Servo AF.

Camera Adjusts Tricky Details.
Canon's exclusive Lens Peripheral Illumination setting takes into account any light falloff in the corners of the frame and corrects it, making for a perfectly exposed image. Correction data are detected automatically on a number of Canon EF lenses and can be entered manually through the included Canon EOS Utility software.

Better Dust Free Performance.
The EOS 50D's Self Cleaning Sensor Unit eliminates stray dust that enters the camera when changing a lens or when out in the field. The sensor's IR-cut/Low-pass filter cleans itself automatically with ultrasonic vibrations every time the camera is turned on or off and features a new flourine coating to minimize dust adhesion. Dust missed by the cleaning unit is captured by Canon's Dust Delete Data Detection software and can be erased from the image file.

Easy Creativity.
The EOS 50D has a new Creative Auto mode and a quick control screen that helps novice users narrow the gap between fully automatic and manual control. While the camera will remain by default in fully automatic mode, frequently changed settings like flash, exposure compensation, image quality and more are all accessible through one easy screen interface designed for intuitive, quick action. A provided shooting guide serves as a quick reference for on-the-fly operation.

Robust, High-Definition Output.
The EOS 50D includes a new HDMI (High Definition Multimedia Interface) output device that enables high definition display of your photographs on any HDTV with HDMI ports. It's remarkable to behold the details of your photographs in Full HD, and it's easy with the EOS 50D. Resolution is set automatically to match the TV to which you’ve connected, and images are displayed in a full-frame 3:2 ratio with blacked out bars to the left and right of the image.

Shooting and Editing Made Easy.
The EOS 50D is compatible with all Canon lenses in the EF and EF-S lineup, ranging from ultra-wide angle to super telephoto lenses. Canon lenses employ advanced optical expertise and micron-precision engineering to deliver unprecedented performance in all facets of the photographic process. Special optical technologies, such as Aspherical, ultra-low dispersion, or fluorite elements are featured in the universally acclaimed L-series lenses. And Canon's Optical Image Stabilizer technology is featured in select lenses to minimize the effect of camera shake. Through Canon lenses, photographers can truly maximize the quality and liberating performance of the EOS 50D.
