LA-EA2: what lenses to get?

Ok, yes I tried that.  There is indeed no noticeable delay with the E mount lens when I press the shutter.  But with the LA-EA2 and SAL35 there is a very noticeable delay.  I'd say it's around a quarter of a second - plenty of time for the subject to move.

Is this normal?  Is the SAL35 particularly slow, or do I have a faulty copy of the lens / adapter?
