Canon EOS 40D

The EOS 40D succeeds the EOS 30D, which in turn succeeded Canon’s 20D model as the company’s mid-range offering. All of these models were intended to be sold at a higher price point than the basic entry-level 300D/350D/400D series since they included a metal construction, quicker continuous shooting, and more complicated controls.

On the other hand, the 30D had an uncommon occurrence. When compared to the lesser model in the line, the 400D, it was a semi-pro camera with an 8MP sensor. However, the 400D featured 10 million pixels. Canon has addressed this issue with the release of the EOS 40D, however, the enhancements made to this camera go much beyond only improving the sensor.

To begin, there is the glaringly obvious. Examining previously captured images and displaying them to others is made considerably simpler by the 40D’s enormous LCD screen, which measures 3 inches. Additionally, it features a Live View mode, in which the LCD screen may be used in place of the viewfinder to compose the image.

The current version of Canon’s DIGIC 3 processor is housed within, and it has a start-up time of 0.15 seconds, better power usage (according to Canon, the battery should last for 800 photos), and greater tone reproduction thanks to 14-bit data.

The rate of shooting in continuous mode also increases. It was already amazing enough with the previous model, but now the 40D can shoot at a rate of 6.5 frames per second. This is double the pace that most cameras in this price range are capable of, and the Canon can maintain this speed for up to 75 JPEGs or 17 RAW files during continuous shooting.

In addition to the “integrated cleaning system” that is now standard on all EOS SLR cameras, the 40D also has a Highlight Tone Priority setting that makes an effort to combat the most common issue with digital sensors, which is blown-out highlights.

The 40D doesn’t necessarily appear to accomplish much more than other 10-megapixel SLRs that cost a lot less money, save from the fact that it can shoot a lot faster than those other cameras. The magnesium alloy chassis is a step up from the plastic construction of lesser cameras, which is a large part of the reason for the camera’s appeal. Its design and build quality are also strong selling points.

It is also somewhat larger than the standard-issue single-lens reflex cameras that are currently on the market, which makes it more comfortable to carry. In addition, it has the same control layout as higher-end EOS cameras, which is based around a trio of dual-function buttons on the top plate and two control wheels: one at the front at the top of the grip and a large, spinning dial on the rear of the camera. In other words, it is very similar to the control layout of EOS cameras which are more expensive.

A monochrome status LCD may be found on the top of the camera. In cheaper cameras, this information is typically displayed on the main LCD, which some users may find to be an annoyance. On the other hand, in contrast to the 400D, the 40D is not necessarily superior in every way.

If you opt to display the information on the 40D’s main LCD, however, it is more difficult to view than the information displayed on the 400D’s information display. The excellent layout of the more affordable 400D model has, in some respects, brought to light some deficiencies in the design of the more costly model’s layout.

Additionally, the rear control dial does occupy the space that is typically allotted to the four-way controller. These four-way functions (mainly for menu navigation) are handled by a little thumbstick, and while it does feel more positive than most, it is still not as nice as a solid Navidad. These functions are primarily used for menu navigation.

A few critical notes, though, but this is simply in contrast to the little 400D, which possesses such an outstanding control structure and user interface that, the more you use it, the more you like it. The controls of the Canon 40D are, in general, quite well designed, particularly in terms of their “feel,” their arrangement, and their accessibility. It will be a substantial improvement over an “amateur” camera for those who are passionate about photography and have already moved beyond the fundamentals.

Canon EOS 40D 10.1MP Digital SLR Camera (Body Only) [International Version, No...

Design And Features

In comparison to the 20D and the 30D, the rear of the 40D has a new button that is labeled as the AF-ON button. This is in addition to the modified button arrangement.

There have also been some noticeable modifications made to the top of the camera. In order to view the ISO setting on the top LCD of the 20D and 30D, you must first push the ISO button. The ISO setting is not shown permanently in the top LCD of these cameras. On the Canon 40D, the ISO setting may now be shown at all times. Additionally, the arrangement of the buttons is a little bit different. The button on the right side of the camera now controls ISO. The ISO setting may be adjusted using the center button on both the 20D and the 30D.

The inclusion of three user settings for the camera is the most noticeable improvement made to the 40D’s shooting mode dial, which is located on the left side of the camera.

Instead of being black coated, the hot shoe that sits on top is now made of stainless steel. In both the 20D and the 30D, the black paint on the hotshoe would eventually wear off in patches. The new hot shoe, which is made of stainless steel, ought to be more wear-resistant.

The 40D has been upgraded to provide some degree of environmental sealing. It is possible to view the seal that encircles the CF chamber. Rather than being made of rubber, the substance is of the “felt” variety.

The little door that may be removed features a seal that encircles the battery chamber. Felt is used in the construction of the sealant as well.

You may show the settings (like you would on the top LCD) on the 3″ LCD on the back of the camera, much like on the EOS 400D, even though the EOS 400D does not have a top LCD on which to display settings.

Image Quality

In comparison to the 20D and the 30D, the playback of images is modified in a few different ways in the 40D.

Even in the most fundamental review mode, the shutter speed, aperture, and folder-file number are displayed. This is a function that was not available on either the 20D or the 30D. Probably because of the increase to 3 inches.

Once you have pressed the INFO button, you will get a display that includes the image recording quality.

If you press the INFO button once more, the screen will switch to display shooting information as well as the B&W histogram.

If you press the INFO button a second time, you will get a histogram for both the color and the brightness of the image. The 20D did not have a color histogram function available. On the 30D, the brightness histogram cannot be presented with the color histogram at the same time.

Autofocus

Autofocus with the 40D’s peripheral sensors is noticeably superior to that of the 20D and 30D, particularly in low-light or low-contrast situations, and this is likely owing to the fact that all 9 of the 40D’s autofocus sensors are of the cross-type sensor variety. In the past, while using the Canon 20D, it was quite challenging to get the focus to lock on with the camera’s periphery sensors in conditions with low light or poor contrast.

The focus would wander about for quite some time before it was able to locate a focus, and there were occasions when it was simply not possible to focus using the peripheral sensors at all. Even in low light or low contrast situations, all of the 40D’s periphery sensors were able to latch on to the correct focus fairly immediately.
