All old EF mount lens can be used on new EOS bodies not compatiblity problem, unlike Nikon you will not need to be manual focus or without metering.

The only problem is the interal reflective of this lens may be larger than new lenses as they were designed for film not for digital but the different is small.

You better use you 40D to try those lens before you buy.

One more additional point, the new L lens has more coating for digital camera.

in short: a lens without or with just a little "chromatic aberration" & "色差"

1. 睇下有冇發霉。

2. 睇下價錢吸唔吸引。
