The 20 has a great reputation for sharpness, but is an older design, focuses slowly because the whole lens barrel moves in and out as opposed to internally focusing like newer lenses, and its motor is kind of slow. It also had a reputation for hunting, and on the Sony sensor of the EM5 vintage, including the Pens, there is the potential for banding, some sort of interference. That has since been fixed with newer sensors and newer bodies with low light capable CDAF abilities.

The 20 on my GX7, with its -4EV focus ability, is now quite acceptable in its speed, though it can still be noisy. It rarely hunts anymore. The newer Oly cams have similar fast focus ability, and so banding and hunting should no longer be an issue, but it is still physically slower.

Just to be clear... which newer Oly. cams are you referring to, Chas2? I've only read that there is no banding with the new PEN-F. All existing OM-Ds are still susceptible to banding because of that Sony sensor you mentioned. As for faster focusing, I don't know about that. Thanks.

As I understand from reading multiple threads on dpreview over the past few months, EM-10 forward for the OM-D range do not appear to have the banding issue for whatever reason.  The older PEN series, prior to the PEN-F seem to continue to use the sensor that bands...so that would mean up through and including the EPL7.
