|Canon EOS 40D - ISO sensitivity
The ISO sensitivity on the Canon EOS 40D ranges from ISO 100 up to and including ISO 1600 and can be enhanced to ISO 3200. Besides that the camera offers auto ISO which lets the camera select an ISO setting between 100 and 800 depending on the program. The camera tends to like ISO 400-800 a lot. It might seem high but the Canon 40D is perfectly capable of dealing with higher ISO sensitivities. Up to and including ISO 400 you have to go through a lot of trouble to be able to find noise. Higher ISO shows some noise but less than average compared with other cameras in the same class. Even ISO 3200 is still very useful although you will encounter some boundaries. Room to correct a picture is lost in this case. However; if the picture is well exposed you won't need to correct it anyway. I have frequently worked with the Canon EOS 40D in dimly lit circumstances and more often than I usually would, I have used ISO 1600. Just because the camera is perfectly capable of dealing with high ISO sensitivities. Worth a compliment!
Canon 40D SLR camera - Dynamic range
The dynamic range is something very special on the Canon EOS 40D. The 40D offers 14 bit files whereas the EOS 30D worked with 12 bit files. And these extra 2 bits get noticed straight away despite the fact the pixels became smaller. Although the development is not that advanced as Fujifilm's two separate pixels, it still is impressive. Of course everything has its limits, so you have to keep an eye on the contrast. If you want to get even more out of your file, you can set 'light tone priority' through custom setting II-3. It needs a bit of calculating and it will decrease the frame speed but it might be worth trying with high contrasts.
Canon 40D digital SLR - Picture Styles
The Picture Styles from Canon are very familiar by now. Canon added even a few more to the Canon EOS 40D. The Picture Styles let you adjust sharpness, contrast, saturation and colour tone. In neutral mode it already delivers fine pictures. The sharpening could be a bit stronger for my taste but Photoshop will do the job here. If you don't want to edit your pictures, just increase the sharpening. Saturation and colour tone are mainly personal preferences. Just try them out to find out what you like best. Unless of course you work in RAW that gives you the option of editing your pictures afterwards. DPP also lets you work with Picture Styles but Adobe software is not compatible. Personally I am very pleased with the neutral setting. Everything does look neutral and it is a perfect base for further finishing.
|Canon 40D - Automatic white balance
If at all I have to comment on the image quality it would be the auto white balance that is too warm in incandescent light. A small detail and only annoying when working with JPEG. But then, my opinion is that one, who purchases a camera like this, should work with RAW only to get the most out of the camera. Of course JPEG can come in handy at times or you can choose to store in both formats at the same time. In any case the white balance gets it right in all the other situations and you can easily create or correct it yourself. Don’t rely too much on what's rendered on the LCD monitor because the image here is too saturated in my opinion and it will give you the wrong idea.
Canon EOS 40D - Save settings
There are many settings available on the Canon EOS 40D. And before you know it, you forgot what it was you did to the settings. That's why you can dedicate the most frequent settings to the buttons C1, C2 and C3. Not only the exposure programs, the sensitivity and white balance can be stored here but also every setting from the menu, for example; aperture. It enables you to save different settings for various circumstances. You have to watch it though if you have temporarily altered something in one of the C-modes, because the camera will go back to the preset mode when it is in sleep mode. I for example set the shutter speed to 1/250. During photographing, with the button on C1, I changed the shutter speed to 1/125s with the intention of shooting with 1/125s for a while. When the camera got activated after having been in sleep mode (you can't keep the camera on your eye forever, can you?), the shutter speed had changed back to 1/250s. The settings in the C-modes can totally differ from other settings; they are not linked at all. If you switch from C1 with an ISO 100 sensitivity, in Tv the sensitivity can even be ISO 400. So keep a close eye on the settings!
Canon EF-S 17-85 IS USM lens
The Canon EOS 40D comes in a kit with a cheap 18-55 EF-S lens or a more expensive EF-S 17085 IS USM lens. I'd strongly recommend the latter. The lens decides the quality of the picture to a great extend so you don't want to economize on the lens. The EF-S 17-85mm lens we have used is a fine combination with the EOS 40D. It delivers hardly any visible purple fringing, not even in wide angle, only a tad of distortion and a pleasant contrast. Also the more expensive L-lenses are great to use with the EOS 40D and they form a perfect combination. Both quality and hand-fit are on a high level.
