Geeze Bill, now I'm confused.
I use the GF1 with the 14 & 20 and thought they were great lenses.
Now I'm unsure. To be honest, I have many Leica lenses in storage. Why? Glad ya asked.
I know that those lenses are simply the best of the best.
If I started to use them, I would once again want an M body.
So far for me, the M bodies are not there yet.
So, I let the lenses sleep.
Does this decision effect my working and images? No!
The GF1 is very responsive to my desires. The 20 & 14 give me the spread in FOV that makes sense to me.
I have absolutely no interference from the camera or lenses. I can't say the same for the M8's I had.
So image wise, no camera or lens ever failed it's mission.
If the shooter blames his gear for an unsatisfying experience, well, time do look in the mirror.
