Hi, I have owned and have extensively used the EOS 5/A2E and EOS 50/Elan IIE bodies and BOTH of these bodies are noticeably faster at locking on and tracking a moving subject when ECF is manually turned off. I only used the EOS 3 for a few days before deciding that it was not for me. The EOS 3 is just not as fast at releasing the shutter as the even the EOS 5QD bodies that I needed to replace so I bought EOS 1n bodies to gain this more responsive feel in AF and shutter release. The EOS 3 is faster focusing and will AF track better than the EOS 1n or EOS 5, no doubt, but it's slower to release the shutter than either of these older pro EOS bodies for some reason and this messed me up in terms of timing to capturing the right moment. I thought it strange that this would be so but even turning off ECF did not make the shutter release any faster on the EOS 3. As to the EOS 3 behaving the same as the EOS 5 and EOS 50 I cannot say definitely but given that the other EOS bodies with ECF benefit from turning ECF off my guess is that the EOS 3 will benefit too but that due to the long delay in shutter release (for whatever reason), there is some software limitation that prevents this from happening.
