The Canon EOS 40D Features and Specification Review

The EOS 40D canon is one of the digits 2 and have a good sensor. also known as a semi pro camera. The EOS 40D becomes the 6th Canon ‘prosumer’ electronic SLR, a range which began returning in 2000 with the EOS D30, and how far we’ve come. It’s been 18 several weeks since the EOS 30D and although on the outer lining the 40D looks like a relatively simple update there’s a lot which creates this an even better electronic camera. Of course we predict a boost in mega pixels, and so the 40D comes with a millions of pixel CMOS indicator with the same kind of dirt decrease as the EOS 400D, an ultrasound program which drinks the low successfully pass narrow.

Canon EOS 40D Body And Design

From the top part at least there are very few changes from the EOS 30D, a little chiseling of the viewfinder area and a new side put on the side hold but overall no actual excitement. The back however has gone through more of a re-design, mostly thanks to the now three inches LCD observe. Several control buttons which ran down the remaining part of the EOS 30D’s observe have now moved to below the EOS 40D’s observe also there’s now a devoted AF-ON key ‘under your thumb’. We should be grateful that Cannon has not eliminated the most ineffective key of all; Immediate Create.

The same components, develop and development as the EOS 30D, a two part mineral magnesium spend that comprises much of the front and rear part of the camera which is well put together with no rattles or creaks, as with past EOS x0D cameras the 40D seems just as strong and efficient.


The EOS 40D gets a new viewfinder which has a higher zoom than that of the EOS 20D/30D (up to 0.95x compared to 0.90x), although in specifications terms this is a simple increase the viewfinder perspective is clearly larger and lighter and still doesn’t experience any distortions or area smooth. As with past designs the eyepiece rubberized is detachable enabling for the eyepiece cover or different eyepieces / tilted locators to be fixed.

Battery Compartment

The battery energy section on the EOS 40D is in the end of the side hold, behind a simple clip- closed entrance. The doorway itself is detachable (to make way for the not compulsory battery energy grip). The EOS 40D is offered the BP-511A Lithium-Ion battery energy power which provides 1390 mAh at 7.4 V (10.3 Wh). There’s a compact entrance on the inside side of the side hold where the wire from the not compulsory AC adapter’s phony battery energy leaves.

Lens Mount

The EOS 40D has a standard steel EF / EF-S lens install meaning that it facilitates all Canon EF and EF-S contacts plus some older as guide focus and suitable 3rd celebration contacts. Because the indicator is smaller than a 35 mm structure all contacts are subject to a area of perspective plants (sometimes called central length multiplier) of 1.6x, thus a 17 mm lens provides the same area of perspective as a 27.2 mm lens on 35 mm movie.

External flash

The EOS 40D’s hot-shoe can be used with Canon and 3rd celebration display designs (sync only). As with the inner display the hot shoes facilitates E-TTL II metering which uses range details from the lens to determine display energy. This harmonizes with all Canon contacts (although range details are only provided by contacts with band type USM motors). You’ll note also the new weather closure encompass which performs together with the more recent 580EX II Speedlite.

Internal flash

The EOS 40D features an E-TTL II pop-up display (same as the EOS 30D and previously 20D), it has a guide number of 13 (approx. 3.3 m @ 17 mm / 2.3 m @ 85 mm; ISO 100) and a wide position coverage of 17 mm. Support for E-TTL II indicates that lens range details are now used to determine the required display energy. Flash synchronize speed is 1/250 sec.

Base / Tripod Mount

On the end of you you’ll find a steel tripod outlet which is arranged exactly with the center line of the lens. Also important to note is the new hold plug at the end right advantage. As I’ve asked for over the opinions it would have been nice to have had a rubberized ‘foot’ at the base of you, although I will think that this could cause you to be not appropriate for the not compulsory battery energy hold.
