Since it doesn’t have on-sensor PDAF, I wouldn’t expect it to be as good as the E-M1 at driving Four Thirds lenses, which are primarily designed for PDAF. I’ve not had a chance to check yet, though.
The E-M1 is one of the best-handling small cameras I’ve ever used, so I wouldn’t quite rate the E-M5 II as highly. The M5 II is smaller, cheaper and prettier, though.

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
