Canon EOS 40D Review conclusion

Canon EOS 40D digital SLR camera
The seven models, from EOS D30 to the 40D, have changed drastically. The image sensor and processor took huge steps forwards and also the DSLR camera itself improved a lot. Can you still imagine how happy a 1.8-inch monitor on the back of a camera made you? The difference with today's cameras is evident and the EOS 40D is a true example of where we stand now and how the technique has advanced. If there are still people who are not convinced of the fact that modern DSLR cameras exceed 35mm cameras, I suggest they work with the Canon EOS 40D for a while!

Canon EOS 40D - Good image quality
The image quality of the Canon EOS 40D leaves little or in fact nothing to wish for. High ISO pictures are still usable. You can shoot using ISO 800 or 1600 without a problem. There is some noise but not annoyingly visible, even less when you convert the pictures with Adobe. Using DPP, noise is visible which gives you a film-feeling from old-fashioned times.

Canon 40D - White balance & Sharpening
The colour rendition of the Canon 40D convinces and I'd be splitting hairs if I tried to find a negative thing. If I have to mention one it would be the auto white balance that is too red in incandescent light. But shooting in RAW or creating your own white balance solves this problem. You could moan about the soft sharpening but you can use Picture Styles to improve it or you can change it afterwards through the software. All in all these are only small details and I wonder: 'What more do we want on this field?'

Canon 40D - Joystick for focus points
If there is any criticism at all it would be the camera itself. For example; I cannot disconnect auto focus and exposure the way I would like to, but this is something very personal as you already might have thought. The joystick however is a more general example. I can hardly get used to it. Its response is not good enough. Maybe I would also like to have an auto focus working on the sensor (Live View). And the monitor could improve with better colours and more pixels. No, not on the sensor for the sensor is perfect. Besides that my personal wish-list has more on it: the metering rendered in the viewfinder would be nice and a GPS connection available without having to purchase an expensive WiFi module. These are all marginal issues though, that have not much to do with the excellent quality of the EOS 40D.

Canon 40D - Outstanding D-SLR camera!
Let's be honest; the Canon EOS 40D is a D-SLR camera that is about the most complete a camera can be. It is a solid camera, with excellent auto focus, a silent shutter and mirror, a beautiful viewfinder and fine operation. On top of that Live View works perfectly, you can walk in the rain with the camera and it is an excellent tool with high quality functions. The minus points are just there because I did my utmost to find them; it was like seeking for the famous needle in a haystack. It is always possible to improve a product although that might be difficult with the EOS 40D. After seven models you might want to admit that we have reached the ultimate consumer EOS DSLR. Outstanding!

Canon EOS 40D - CompactFlash memory card
The Canon 40D delivers considerably large files especially in RAW. This is not entirely because of the ten Megapixels but also because of the 14 bits. A RAW file generates a 12.4MB file size. That asks for large storage cards. Even more so if you want to shoot in JPEG and RAW at the same time. If you need the captured pictures only for the Web, you can decide to use sRAW. The file size will then be some 7.1MB. In practice it comes down to the fact that you need at least a 2GB card, when you work in RAW. If you are reporting and sent out on an assignment, you will have to get a 4 or 8GB memory card. And a holiday will require several cards unless you empty the one on your laptop or image tank. The table below shows how many pictures fit on a 1GB CF memory card.

Considering 1GB storage capacity:
RAW - 3888x2592 pixels - 76 pictures
sRAW - 1936x1288 pixels - 135 pictures
RAW + JPEG Large Fine - 3888x2592 pixels - 59 pictures
RAW + JPEG Large Normal - 3888x2592 pixels - 66 pictures
RAW + JPEG Medium Fine - 65 pictures
RAW + JPEG Medium Normal - 70 pictures
RAW + JPEG Small Fine - 69 pictures

sRAW + JPEG Large Fine - 90 pictures
sRAW + JPEG Large Normal - 107 pictures
sRAW + JPEG Medium Fine - 103 pictures
sRAW + JPEG Medium Normal - 116 pictures
sRAW + JPEG Small Fine - 1936x1288 pixels - 115 pictures
sRAW + JPEG Small Normal - 1936x1288 pixels - 124 pictures
JPEG Large Fine - 3888x2592 pixels - 274 pictures
JPEG Large Normal - 3888x2592 pixels - 523 pictures
