Base / Tripod Mount

The tripod mount retains its position, though there's still not much in the way of grip to help secure it to a tripod plate. A rubber cover protects the connecter (for communicating with the optional WFT-E3A wireless grip).

Internal flash

The EOS 50D features an E-TTL II pop-up flash (same as the 40D, 30D and 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.

AF Assist

As per most previous Canon DSLRs, the 50D 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.

External flash

The EOS 50D'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.

Lens Mount

The EOS 50D has a standard metal EF / EF-S lens mount which means that it supports all Canon EF and EF-S lenses plus 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.
