PanaLeica 25mm f1.4 autofocus performance
May 30, 2013

I've been playing with a Panaleica 25mm (the four thirds variant) and have been getting very poor performance with the autofocus on my E1, E-30 and E-5. At close range, around 1/3 of shots are well focused, the rest a mix or front and back focus. At longer range, (10 metres+) the success rate falls off even further.

I've been testing at f1.4, both to get a good shutter speed and to ensure that increased DOF doesn't mask focus errors. I've tried in good and bad light using objects with good contrast s focus targets.

I'm probably going to send the lens back, but the in-focus results are stunning so if anyone has any thoughts on whether the AF can be improved I'd like to hear them. Is this  the sort of issue that can be rectified by a service adjustment, or is there likely to be some fault with the lens?

Thanks

Mario
