I was checking the features of both of these and found out that the 20Da 'focus feature' on the LCD screen does not work with any Canon all electronic lens, such as my 300mm.See

I am now seriously considering a modded 5D from Hutech as it is about $5K Aus + $500 GST + $49 handling fee as opposed to a 20Da about $3K+ Aus. The other advantage of the 5D it has less than half the noise and a sensor with 2.5 times the area.
The only advantage the 20Da had was that focus feature.
Can anyone shed some light on this (no pun intended). I know Striker has one, so please let me know.
