Since SLT uses only a third stop of light for AF, it would put it far behind in that area (conpared to SLRs) as well.--

A traditional dslr uses also a fraction of the light hitting the mirror. There is a secondary little mirror inside the main mirror which is used for phasedetect autofocus. And the rest of the light goes up to the viewfinder. So your statement is not correct.

And the autofocus on an slt works always, on a dslr the AF doesn't work when the picture is taken because the mirror goes up.

That is not my statement. I happen to have combined te rhetoric from anti-SLT brigade to show how they believe SLRs create their own light... they have to if the total sum is more than 100% of the light.

Whereas in reality, the SLR tech uses splitting into three optical paths: OVF, metering and AF.

It is amazing to me the numbers of SLR / OVF defenders who don't even know how it works..
