remote operation is now possible with Canon’s small, affordable Wireless Remote Controllers

RC-1 or RC-5. The optional Wireless Remote Controller RC-1 can be used to start and stop

recording videos in addition to its normal still picture function. But to start and stop recording

videos, it must be set to the 2-sec. timer delay mode while the camera is in Live View mode.

Despite the increased number of megapixels on the EOS 50D compared to the 40D, the

maximum burst speed remains almost the same, at 6.3 fps, with bursts up to 90 shots

( JPEG, Large/Fine in high-speed continuous mode using a current UDMA CF card), up to

17 shots in RAW, and up to 10 shots in RAW+JPEG Large/Fine mode. With its outstanding

frames-per-second speed and extensive burst rate, the EOS 50D is a superb, affordable choice

for sports, action, event and wildlife shooters looking for a lightweight, affordable digital SLR.

Equally impressive, the 21.1-megapixel EOS 5D Mark II features an improved shooting speed

of up to 3.9 fps compared to the older 12.8-megapixel EOS 5D—despite its significantly

higher megapixel count. The burst depth of the EOS 5D Mark II for Large/Fine JPEG

images is only limited by the capacity of the memory card when using UDMA CF cards,

or up to 14 consecutive frames in RAW, or up to 13 consecutive frames in RAW+JPEG

Large/Fine. This exceptional performance is made possible by improvements in the CMOS

sensor with 4-channel, high-speed signal reading; DIGIC 4's excellent high-speed image

processing; and the camera’s DDR2 SDRAM high-speed memory buffer.

The duration of a continuous burst, not its maximum speed, can be affected by the speed of

the memory card used. That’s why Canon included support, in both cameras, for ultra-high

speed Ultra Direct Memory Access (UDMA) cards up to a Mode 6 rating (max. transfer

speed of up to 133MB/sec.). While Mode 6 UDMA cards aren’t available yet, these two

cameras will support them when they arrive. Existing UDMA cards currently run as fast

as 45MB/sec. and are the fastest available. When used, UDMA cards maximize the data

transfer rate in both directions between the cameras, enabling nearly twice the speed of

data transfer on the EOS 50D compared to the EOS 40D.

More and more photographers are becoming aware of the benefits of displaying their photos

on large HDTV screens or with high-resolution video projectors on bigger screens. But

there’s never a good laptop available when you need one, so Canon equipped both the EOS

50D and the EOS 5D Mark II with HDMI connection jacks in addition to regular A/V

jacks. With the addition of an optional HDMI cable, not only can HD videos with sound be

displayed on HDTV systems using a single cable connection, but also slide shows of still

photos can be displayed at nearly 2.0-megapixel resolution (1920 x 1080 pixels) on HDTVs

or on larger screens via HD capable video projectors. That means you can store your portfolio

images on a special card (with retouching as necessary), load them back into the camera,

and use it to run your large-screen presentations.
