Base / Tripod Mount
The EOS 40D features an E-TTL II pop-up flash (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 angle coverage of 17 mm. Support for E-TTL II means that lens distance information is now used to calculate the required flash power. Flash sync speed is 1/250 sec.
As per previous x0D DSLRs the EOS 40D uses the internal flash for AF assist. Instead of having a separate lamp to provide assistance to the AF system in low light you have to raise the flash unit which will strobe to provide illumination for AF.
|The EOS 40D's hot-shoe can be used with Canon and third party flash units (sync only). As with the internal flash the hot shoe supports E-TTL II metering which uses distance information from the lens to calculate flash power. This works with all Canon lenses (although distance information is only provided by lenses with ring type USM motors). You'll note also the new weather seal surround which works in conjunction with the newer 580EX II Speedlite.|
The EOS 40D has a standard metal EF / EF-S lens mount which means that it supports all Canon EF and EF-S lenses plus some older as manual focus and compatible third party lenses. Because the sensor is smaller than a 35 mm frame all lenses are subject to a field of view crop (sometimes called focal length multiplier) of 1.6x, thus a 17 mm lens provides the same field of view as a 27.2 mm lens on 35 mm film.
Shutter Release Sound
In some of our digital SLR reviews we now provide a sound recording of a continuous burst of shots. Below you can see waveforms of a recording made of the EOS 40D shooting continuously JPEG Large/Fine for 30 seconds. The storage card used was a 2 GB SanDisk Extreme IV Compact Flash.
