My experience with the new 20/1.7 on my GX7 mirrors that of Anders - if it's focusing on something not near it's pretty quick. It takes about a second to rack all the way from MFD to infinity which can seem like forever if you are in a hurry. Small AF changes at far distances are pretty fast - fast enough at least.

Also, it seems to me that the size of the AF point box seems to affect it as well - i.e., the smaller the size of the AF box the slower it is and is somewhat less reliable, but it may just be me.

Thanks all. Now my question then is: do other fast primes work similarly or are newer ones better in that respect. Af speed is my main issue with non-dslrs, I want to corner that wrt m43 before I move into the system.

The 'newer' primes have an internal focusing thingy; the front element doesnt move. Therefore they focus blisteringly quickly.
