Canon EOS 40D Reviews

Great Balance and Feel of Quality

This camera just feels right!!! Its controls are in the right spots (with the exception of the on/off switch). The magnesium alloy body is rock solid leaving you with a reassuring feeling that this bad boy can take a licking. I found the menu quite easy to follow & intuitive. Despite its weight, the camera is well balanced… even with a lens attached. Picture quality is top notch. Even though it utilizes a 10.1 megapixel sensor, it does so with improvements in the microclines design on the sensor & a better processing engine for improved images & performance… not to mention 14 bit processing. The addition of dust removal is a welcome addition & should prove worthy. Although Canon claims weatherproofing, it is limited to specific areas of the camera & not throughout the camera body as the Nikon d300 has. But it's also $500 to $600 less than the Nikon!!! That's the price of an additional lens. Its shutter has also been upgraded to pro levels with a durability rating of 100,000 cycles… not bad. Additionally, the mirror mechanism has been improved with the elimination of the spring mechanism, replaced by a "servo" motor making it much quieter. Overall, the shutter sound has become much quieter & just sounds "professional". The pentaprism is gorgeous… very bright giving you the added capability to focus with very little, if any, difficulty. Some people have complained about the positioning of the DOP button. They keep insisting that it belongs on the right side of the lens. Personally, I like it just where it is. My left index finger falls right where the button is… for me it's "right on". I'm not into "Live View" & don't use it so I'll reserve judgment on this. But I can say that the new 3" LCD screen is extremely bright. Despite its lower resolution compared to the Nikon d300, I found it to be quite satisfactory in reviewing images & reading the menu. The increase in size, for me anyway, was more important than greater resolution. Bottom line: If you're looking for great value in a"prosumer" camera, this is it. It's a lot of "Bang" for your "Buck" & should give you years of service & awesome pictures.

Canon EOS 40D Digital SLR

I've used a wide spectrum of digital SLRs, from entry-level models up to pro models. Once you have a taste of the capabilities of a professional camera, you can't easily go back to a digital SLR that's less full-featured; likewise, if you want to step up from an entry-level digital SLR, you have to get something with extra oomph. The Canon EOS 40D ($1300 body only, or $1500 with a 28mm to 135mm lens, as of November 2, 2007) delivers outstanding image quality at a price that's in reach for photo enthusiasts and professionals alike.

The EOS 40D received a score of Superior in the PC World Test Center's image-quality tests. Images were well balanced, with good color saturation and accuracy, under both flash and natural light.

One of the EOS 40D's advantages is that it has enough high-powered features to appeal to enthusiasts as well as to professionals seeking a second camera. It has many of the same capabilities, in fact, as its higher-end cousin, Canon's $4500 1D Mark III, which the company introduced this past spring. The two models share a 3-inch, live-view, 230,000-pixel LCD; Canon's DIGIC III image processor; highlight tone priority for preserving the details in bright areas of an image; and similar menus and controls.

This camera has a 10.1-megapixel, 1.6-focal-length-factor CMOS imaging sensor (up from 8.2 megapixels on the EOS 30D), which is faster and provides better color accuracy than that of its predecessor. The EOS 40D can shoot at up to 6.5 frames per second, up to a maximum of 75 Large/Fine JPEGs or 17 RAW images. That speed will be particularly helpful for shooting in a variety of special circumstances—such as when you're trying to capture a gymnast's back handspring on the balance beam.

The EOS 40D has a nine-point autofocus sensor, as the 30D had. But this model's version has been completely redesigned so that all nine components are cross-type sensors—an approach that makes it more likely that the sensor will lock on to your subject, since the sensors are reading both the horizontal and vertical areas. The autofocus proved fast and accurate in my hands-on tests: I had no difficulties capturing sharp images of the U.S. Navy's elite flight team, the Blue Angels, as the jets zoomed overhead during an air show. Even more impressive is that I could capture them rapid-shot, and didn't feel at all at a disadvantage as compared with using an 8-frames-per-second 1D Mark II. Other features such as the ability to add a transmitter to wirelessly control the EOS 40D and send images from it will appeal to professionals seeking a backup or secondary-use camera.

The menus and controls on the EOS 40D are similar to those of other models in Canon's digital SLR line; if you're moving up from a Digital Rebel or migrating down from models such as the EOS 5D or the 1D Mark II or Mark III, you won't take long to master this model. I particularly liked how the jog dial worked with the four-way joystick to navigate through the clean menu system.

Another benefit the EOS 40D has over its predecessor: It integrates a multitiered dust-reduction system like the one Canon already has in place for its Digital Rebel XTi and 1D Mark III. As an avid photographer, I find this feature the most exciting: Dust is the bane of any active digital SLR photographer's existence, and is the primary enemy you need to worry about every time you swap lenses. (Read more in "The Dirt on Digital SLRs' Dust.") You can set the sensor to self-clean whenever you start the camera; in my experience, the process was so quick that it didn't cause any tangible delay in shooting. While I have not done a scientific study of how good Canon's dust-cleaning system is, I can report that during my tests I swapped out lenses several times in less-than-pristine, open-air conditions—and the images I've taken appear to be dust-free so far.

Like most cameras, though, the 40D has a few frustrating quirks. My biggest gripe: The image I saw through the viewfinder didn't quite match up to what the sensor captured. Using the 28mm to 135mm lens that came with the 40D, I repeatedly found that I would get just a bit more around the edges of my image than what I saw through the viewfinder. That meant retaking some shots so that I could frame the image correctly without resorting to an image-editing program. I also disliked that in Program mode, you can't change the ISO setting; in this mode, the camera automatically controls the ISO.

The strengths of the Canon EOS 40D overshadow those minor drawbacks, however. On the whole, it is a powerful, scalable camera. If you're graduating from a Rebel-series digital SLR, this is a great step-up model whose versatility will grow along with you. And if you're a more advanced shooter or a pro looking for something smaller and less costly than Canon's top-tier cameras (the 1D and 5D series), this camera is perfect for you.

Upgrading from the Canon Rebel XTi to the Canon 40D

These are my personal thoughts and feelings from the first days with my new Canon 40D after having had a Canon Rebel XTi for about a year and a half after having taken about 30,000 photos with the Rebel and now about 2,000 with the 40D. These are only my personal feelings your mileage may vary.


Favorites menu!
Auto ISO in all modes
1/8000th shutter speed and 3200 ISO at last!
Flash using Canon Speedlite 430EX is right on the money!
Super fast in all aspects: turn on, operation, auto focus, shooting
Great feel in the hands, fits like a glove, I could shoot all day long!
Rear LCD screen, OH MAN this thing rocks: super bright big and accurate
Raw files you gotta love, very good noise control, responsive and colors to lust after
High speed 6.5 fps shooting! I have yet to hit the limiter when shooting high speed


Power Switch location
Rear LCD shooting info has to be turned on each time and no auto-off when brought up to face
Camera user settings C1, C2, C3 lose on-the-fly updates when camera goes to sleep
Neutered auto ISO range only goes up to 800 ISO.

It fits my hand like a glove; I especially love the rubberized coating around the right grip.

Where did everything go? My power switch and screen display. You better have your owner's manual handy because this is a different camera from the Rebel XTi.

WOW this camera shoots fast! It has a precision to it and speed both in focus and number of shots my Rebel just does not have. Got to buy more CF cards though as they fill fast shooting in Raw at 6.5 FPS and they are bigger then the old Rebel Raw files.

I continue to be impressed with the ability of the Canon 40D Raw images. Not only are they a leap beyond the XTi Rebel in appearance they respond much better to changes in Adobe Raw. I especially like how responsive the 3200 ISO shots are to the noise filters. ISO 3200 once I process it through CS3 Raw noise reduction actually looks like my Rebel looked at 400 ISO!. And the colors man oh man they are breath taking.

Speaking of breath taking! The rear LCD is amazing. I haven't had to touch the brightness at all which is good because I have a really good idea if the image came out or not. Not so on Rebel where I had to run the brightness all the way up on the rear LCD and so could not judge if the exposure was correct not to mention it was hard to see the photo itself. This 40D screen is huge bright and breathtaking.

And I love the favorites menu. Set your own deeply buried and needed settings right there. Like mirror lockup! Or live view!

Love the grip that rubber really helps me get a grip!!

Now for the now so good. Who the hell decided to put the on off switch down on the bottom middle? I swear I have reached over with my right thumb by habit a dozen times to turn the camera on and off.

What the heck? On the C1, C2, C3 settings if you make any adjustments on the fly and then the camera goes to sleep the settings go away. Will have to make a short cut under favs to adjust the settings on the fly.

All in all though I continue to love this camera and after shooting it for a little over a day I picked up the Rebel XTi and it felt like a small unresponsive plastic toy!!!

I will continue to update this review as I have more time, right now I'm at about 2,000 photos.

3-11-2008 Update

Went out with the Canon 70-200 F/2.8 L lens on servo mode high speed 6.5 fps setting and had a blast. I tracked cars, planes, birds in flight, this baby just locks on and keeps tracking. My Rebel would maybe get one or two in focus frames of a bird in flight that was it. This 40D I can get 10 to 20 all in razor sharp focus before the bird is out of view. I'm practicing on pigeons around the house so they aren't in view for long. Can hardly wait to try it out on some bigger birds as it would be a cakewalk.

3-13-2008 Update

Flash using Canon Speedlite 430EX is right on the money! Let's face it, there are times you just have to use flash. And with my old Canon Rebel XTi it was a chore. The Rebel's flash metering was almost always off and inconsistent. What a pleasure to find the flash exposures with the Speedlite 430EX mounted on my Canon 40D to be nailed right on the money every time.

The 40D continues to delight!
